Tsunami MP.11 Antenna Installation

ABOUT THE TSUNAMI MP.11 PRODUCT FAMILY

The Tsunami MP.11 models let you set up a wireless system based upon two basic topologies:

• A point-to-point link, which lets you set up a connection between two locations as an alternative to:

Leased lines in building-to-building connections

Wired Ethernet backbones between wireless access points in difficult-to-wire environments

•

A single point-to-multipoint network, which lets you connect more than two buildings. You can set up a single

point-to-multipoint network with a single Base Station Unit and multiple Subscriber Units.

A link between two locations always consists of a Base Station Unit (BSU) and a Subscriber Unit (SU). A BSU

can, depending upon its configuration, connect to one or more SUs; an SU, however, can connect to only one

BSU.

Note: Depending upon local radio regulations and legislation, the outdoor antenna solutions described in this

document may not be available in all parts of the world.

Tsunami MP.11 Antenna Installation

SAFETY PRECAUTIONS

Read this section carefully before beginning the installation. All of the following requirements should be satisfied

prior to starting installation of your outdoor antennas.

DANGER!

The outdoor antennas to be used with this product are intended for mounting on a roof or on the side of a

building. Any person not trained or experienced in this type of work should not attempt this installation. A suitably

trained professional installation technician must install the antenna. The site prerequisites must be checked by a

person familiar with the National Electrical Code, and with other regulations governing this type of installation.

Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic discharges that may

occur at the antenna (such as a lightning strike during thunderstorms) may damage your electronic equipment

and cause personal injury or death to persons touching the exposed metal connectors of the antenna cable.

When installing, disconnecting or replacing one of the cabling components, you must ensure at all times that each

exposed metal connectors of the antenna cabling system are grounded locally during the work.

Do not install this antenna where there is any possibility of contact with high-voltage arc-over from power cables

or service drops to buildings. The antenna, supporting mast, or tower must not be close to any power lines during

installation or removal, or in the event part of the system should accidentally fail. Apply a Danger label to a plainly

visible area of the antenna support structure.

Do not climb rooftops in wet or windy conditions, during a thunderstorm, or when the area at which the equipment

is to be installed is covered with ice or snow.

Do not touch antennas, surge arrestors, or antenna cables during a thunderstorm.

The antenna installation location must be at a safe distance from power lines or telephone lines. The safe

distance should be at least twice the height of the antenna mast plus the height of the antenna.

Antennas shall be mounted in such a manner as to minimize the potential for human contact during normal

operation. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the

antenna shall not be less than 20 cm (8 inches) during normal operation.

The low-loss antenna cable that is to connect the antenna with the surge arrestor, or with the Ethernet cable that

is to connect to the surge arrestor, must be at least 1 m (3 ft) away from any high voltage or high current cable.

Check whether the antenna mast and its guy wires or wall bracket are positioned correctly and secured properly

to the roof or walls.

Check whether the grounding system for the antenna mast, the MP.11a and 5054-R hardware, and the surge

arrestor have been installed. The grounding system must comply with the requirements as described in

“Grounding the Antenna.”

Always consult a qualified electrician if you are in doubt as to whether the antenna mast, the surge arrestor, and

the hardware are properly grounded.

The antenna cable between the antenna and the surge arrestor must be grounded at all times. If the cable is

disconnected at one end for some reason (for example, to replace the surge arrestor), you must ensure that the

exposed metal connector of the cable is grounded locally during the work.

Tsunami MP.11 Antenna Installation

Chapter 1. Preparing for Installation

Plan the day for your outdoor antenna installation carefully. Do not install the antenna in wet or windy conditions,

during a thunderstorm, or when the area in which the equipment is to be installed is covered with ice or snow.

The grounding system for the antenna mast, radio hardware, and surge arrestor should be installed before the

cable from the antenna is connected to the surge arrestor. This protects your system against lightning strikes

during installation.

Familiarize yourself with the antenna and the antenna-specific mounting instructions prior to climbing any roof or

ladder. By installing and testing all equipment before beginning the actual rooftop installation, you can determine

whether all required equipment and items are available and functioning properly.

To verify the equipment prior to installation, you may first need to follow the guidelines as described in the

documentation that comes with the radio unit.

INSTALLATION PROCESS OVERVIEW

The installation process can be summarized in the following steps:

1. Verify that the support structure for the antenna has been connected to the grounding system. If this is not the

case, you should do so now.

2. Connect the exposed metal connectors of the low-loss antenna cable to the grounding system.

3. Mount the antenna to the support structure, following the guidelines as described for your antenna.

When mounting multiple antennas on a single mast, use the following methods to minimize the influence of

cross-talk interference between the antennas:

– Place your antennas as far apart as possible.

– Alternate the mounting of directional antennas for vertical and horizontal polarization.

Consult the mounting instructions for your antenna as described in Tsunami MP.11 Recommended Antennas

for options and instructions for mounting the antennas for different polarization.

4. Connect the antenna cable to the antenna.

5. Route the antenna cable to the surge arrestor that has been installed near the ingress point.

6. Connect the antenna / Ethernet cable to the surge arrestor.

7. Attach the surge arrestor to the N-type female bulkhead connector.

8. Run the Link Test diagnostics of the management tools that come with the radio unit to aim the antenna and

verify optimal placement.

Note: You can use the unit’s Antenna Alignment Display utility. See “Aligning the Antenna.” on page 19

9. Once the antenna is correctly positioned, and you have verified the installation works properly, secure all

cables and use weatherproofing tape to seal all outdoor connectors.

Note: When you must remove or relocate the antenna, follow the Safety Precautions at the beginning of this

chapter and follow the steps listed above in exactly the reverse order.

Tsunami MP.11 Antenna Installation

The electronics (power supply and radio) are designed for indoor mounting and operation. The ideal location

must satisfy the following requirements:

•

The location provides a connection to a grounding type AC wall outlet (100-240 VAC), using the standard

power cord supplied with the unit. (Alternative power can be provided through Power over Ethernet.)

•

The ground of the AC wall outlet must be connected to the same grounding system as the surge arrestor and

antenna mast (see “Grounding System” on page 19).

•

The location must allow for easy disconnection of the radio hardware from the AC wall outlet.

The location provides a connection to the network backbone (an Ethernet LAN cable that is connected to a

hub, bridge, or directly into a patch panel)

•

The location is as close as possible to the point at which the antenna cable is to enter the building (see

“Placement of the Surge Arrestor” on page 13).

The ideal location has a temperature of 0–55º C and a maximum relative humidity (non-condensing) of 95%.

CAUTION! The radio hardware, the surge arrestor, and the antenna mast must be connected to the

same grounding system.

Outdoor Hardware Placement

The 2454-R and the 5054-R are designed for outdoor mounting and operation.

To make optimal use of the units, you must find a suitable location for the hardware. The radio range largely

depends upon the position of the antenna. Proxim recommends you do a site survey, observing the following

requirements, before mounting the hardware.

•

The location must allow easy disconnection of the unit from the power outlet if necessary.

The radio units must not be covered, and air must be able to flow freely around it.

The radio units must be kept away from vibration and excessive heat, and must be kept free from dust

buildup.

•

The installation must conform to local regulations at all times.

The location provides a connection to the network backbone (an Ethernet LAN cable that is connected to a

hub, bridge, or directly into a patch panel).

•

The location is as close as possible to the point at which the antenna cable or Ethernet cable is to enter the

building (see “Placement of the Surge Arrestor(s)” on page 13).

CAUTION! The radio hardware, the surge arrestors, and the antenna mast must be connected to the

same grounding system.

Tsunami MP.11 Antenna Installation

Cable System

Prior to mounting the radio unit, you are advised to carefully calculate:

•

The distance between the intended location of your unit and the location of the antenna mast

The height of the antenna on the mast

If the low-loss antenna cable for the unit is not long enough to cover this distance, you either can select another

cable length from the Proxim Systems low-loss cable offering, or select another location that satisfies the

requirements previously listed to mount your unit. The radio unit can be placed anywhere, as long as Ethernet

cable length allows.

Because the length of the antenna cable can affect the actual range of your outdoor antenna installation, Proxim

recommends selecting another location or using the 5054-R model.

WARNING! You must not change the length of the low-loss antenna cable used with the 5054 to a length

shorter than allowed by the radio’s certifications. Shortening the cable voids the Proxim

Wireless Corporation warranty and can conflict with radio certifications or approvals.

Installing the radio unit is described in the Installation and Management manual as well as the Quick Install Guide,

which come on the product CD.

Surge Arrestor Placement

The surge arrestor is an indispensable part of your outdoor antenna installation. It protects your sensitive

electronic equipment from transients or electro-static discharges at the antenna.

For optimal protection, the surge arrestor must be installed at a location that satisfies the following requirements.

A location:

•

As close to the location at which the Ethernet cable will enter the building

That allows for easy disconnection of the surge arrestor from the cable connected to the unit.

Antenna Cable Route

The antenna cable must be connected from the antenna through the surge arrestor to the antenna connector of

the unit.

To plan the route of the antenna cable for an indoor unit (5054), consider the following :

•

Does the cable route require drilling through a wall or ceiling?

Do you have a building plan of the desired location showing other cabling routes such as electricity, telephone

or networking?

•

Does the type of building materials require special drilling tools?

The cable should not be installed into tight positions, as bending or applying excessive force to the connectors

can damage the antenna cable. Always allow the cable to bend naturally around corners. The recommended

bend radius is at least 100 mm (4 in) or more for the low-loss cable of 10 mm (0.4 in) and 15 mm (0.6 in)

diameter.

Tsunami MP.11 Antenna Installation

CAUTION!

•

The cable must be secured along the complete distance between attachment points. No part of the

antenna cable should be allowed to hang free. This is particularly important for outdoor cable parts.

•

The antenna cable and cable connectors are not designed to withstand excessive force:

Do not use the connectors as ‘cable grips’ to pull cable through raceways or conduits.

Do not use the cable connector to support the weight of the cable during or after installation.

Do not use any tool to tighten the connectors.

•

Always seal the connectors using weatherproofing tape.

Avoid any water or moisture entering the cable as that impacts the performance of the wireless link.

Prior to sealing the outdoor connectors and permanently securing the cable to the wall with cable ties

and wall hooks, verify whether the installation and all components functions properly.

OUTDOOR LINK INSTALLATION

The outdoor installation of the link (point-to-point or point-to-multipoint) requires the following:

•

An antenna or unit with an integrated antenna

A low-loss antenna cable (available in four lengths)(not for unit with integrated antenna)

Antenna mast or wall bracket for the antenna / unit

A grounding system that meets the requirements described in “Grounding the Antenna” on page 19

Waterproofing of all connections

Note: All outdoor cable connectors must be sealed with weatherproofing stretch tape to make the connectors

permanently waterproof. See “Sealing the Cable Connectors” on page 18.

DANGER! For your own safety, the antenna mast and the grounding system should be installed only by

experienced installation professionals who are familiar with local building and safety codes

and with the National Electrical Codes (NEC). Read carefully the instructions described in

“Grounding the Antenna” and verify that your installation complies with the appropriate

regulations and codes before installing the antenna.

Placing the Antenna

To achieve maximum performance of your wireless outdoor link, the outdoor antenna must have clear line-of-sight

to the antenna of the other unit. Although the radio signal can work well without line-of-sight in urban

environments in which the signal is transported by reflection rather than being direct, the best results are achieved

in line-of-sight conditions.

Line-of-sight can be defined as:

•

No obstacles in the direct path between the antennas (antenna beam)

No obstacles within a defined zone around the antenna beam

You should be aware that the shape of an antenna beam is not straight and narrow like a laser beam. The

antenna beam, also known as Fresnel²Zone, is rather bulged in the middle, such as, for example, a rugby ball.

²Pronounced as ‘Fray-Nell’

Download from Www.Somanuals.com. All Manuals Search And Download.

Tsunami MP.11 Antenna Installation

The definition of the 1^stFresnel zone is an imaginary boundary line offset along the direct signal path. This

boundary is defined as the point where if a signal were reflected between the two antennas, it would travel a

distance exactly one-half wavelength longer than the direct-path signal. Each succeeding Fresnel zone boundary

adds an additional half-wavelength to the reflected path distance between the antennas.

Signals reflected from any even-numbered Fresnel zone result in signal cancellation; those from odd-numbered

Fresnel zones add to the direct path signal.

The exact shape and width of the Fresnel Zone is determined by the path length and frequency of the radio

signal. The width as distance from the direct antenna beam is approximately 6 m (21 ft) in the middle of the

wireless link for a distance of 6.5 Km (4 mi) and a frequency of 5.8 GHz. This width also is the required clearance

of the antenna beam from obstacles in its path, to avoid loss of radio signal.

When any significant part of this zone is obstructed, a portion of the radio energy is lost, resulting in reduced

performance. Reduced performance also can occur when obstacles close to the antenna beam cause signal

reflections or noise that interfere with the radio signal.

The following figure shows some typical examples of obstacles you must avoid for the directional antenna to

operate effectively:

a. Neighboring buildings

b. Trees or other obstructions

c. Power lines

For optimal performance, you must ensure that the type and placement of the antennas leave sufficient clearance

of the Fresnel Zone at the maximum width of the bulge, which is typically at the mid-point between the antennas.

Tsunami MP.11 Antenna Installation

To minimize the influence of obstacles, signal interference, or reflections, note the following guidelines:

•

Mount the antenna as high as possible above the ground to allow maximum clearance:

In open areas, ground is the actual surface of the earth.

In dense urban areas, ground is to be interpreted as the height of the highest obstacle in the signal path

between the two antenna sites.

•

Avoid trees in the signal path to avoid signal absorption due to seasonal changes (leaves or ice).

Install the antenna at least 2 m (6 ft) away from all other antennas.

Other situations, in which reflections of the radio signal may cause interference, are environments in which large

reflecting surfaces exist in parallel or partly perpendicular to the antenna beam.

Environments with large reflective surfaces include:

•

Mirror-glass buildings

Crowded parking lots

Water surface or moist earth and moist vegetation

Above ground power and telephone lines

Note: The use of reflective surfaces can be used to improve a link, especially if the direct line-of-sight is impaired

or absent.

Weather conditions such as rain or snow usually do not have much impact on the performance of your Proxim

product, provided you have sealed all cable connectors with weatherproofing tape.

Seasonal influence on signal propagation can occur in the following situations:

•

A marginal communications quality in late fall (with no leaves on the trees in the signal path) might fail in the

summer

•

In winter, a wireless link can fail when the antenna is exposed to ice buildup or when the antenna elements

are covered with snow

Radio paths over water or extremely flat ground may require optimization of antenna height at one end. This is

due to in-phase or out-of-phase reflections. Adjustment of antenna height by 1 to 3 meters may move the signal

from a null to a peak.

Long distance links may be obstructed by earth curvature, so the antenna height requirements must not only take

the height of obstructions and Fresnel Zone into account, but also earth bulge. The earth bulge is approximately

5 m (16.4 ft) at a link distance of 16 Km (10 mi).

In these cases, consult your supplier to take appropriate steps to maintain or optimize wireless link performance.

Tsunami MP.11 Antenna Installation

Mounting the Antenna

As the mounting procedures for the various antennas differ from one another, consult the documentation

you received from the manufacturer for mounting procedures.

Proxim Wireless Corporation offers multiple antennas to set up a wireless link (as well as a unit with an integrated

antenna).

When mounting multiple antennas on a single mast, use the following methods to minimize the influence of cross-

talk interference between the antennas:

•

Place your antennas as far apart as possible

Alternate the mounting of directional antennas for vertical and horizontal polarization

There are two frequently used methods to erect an antenna mast:

Tripod Mount

The tripod mount is used primarily on peaked and flat roofs. The antenna mast must be secured to the roof

using three or four guy wires equally spaced around the mast. When the height of the antenna mast is more

than 3 meters (10 ft), you should use at least three guy wires for each 3-meter (10-foot) section of the mast.

Wall (Side) Mount

A wall (side) mount allows for mounting an antenna (mast) on the side of a building or on the side of an

elevator penthouse. This provides a convenient mounting location when the roof overhang is not excessive or

when the location is high enough to provide a clear line-of-sight.

In most situations mounting an antenna directly to the wall does not let you align the antenna properly with the

corresponding antenna at the opposite end of your wireless link. As poor alignment typically results in poor

performance, Proxim recommends always mounting the antennas to a mast.

Antenna Mast Requirements

To accommodate the antennas, the antenna mast must satisfy the following requirements:

•

The construction of the mast must consist of sturdy, weatherproof, and non-corrosive material (for example,

galvanized or stainless steel construction pipe).

Typical diameter of the mast should be between 35 mm (1.4 in) and 41 mm (1.6 in) (up to 4 in for 5054-R)

Depending upon the type of antenna you intend to install, other diameters also may be possible.

The height of the antenna mast must be sufficient to allow the antenna to be installed at least 1.5 m (5 ft)

above the peak of the roof. If the roof is of metal, the height of the antenna should be at least 3 m (10 ft)

above the roof.

•

The mast or wall bracket must be free from any substance that may prevent a good electrical connection with

the antenna (for example, paint).

Tsunami MP.11 Antenna Installation

Connecting the Antenna Cable

Once the antenna is properly installed, you can connect the antenna to the unit by way of the surge arrestor:

1. Connect the antenna cable to the antenna.

2. Secure the antenna cable to the mast so that the cable connectors do not support the full weight of the cable.

3. Connect the opposite end of the antenna cable to the surge arrestor (see “Surge Arrestor Installation” Error!

Bookmark not defined.).

CAUTION! To avoid damage to the antenna cable and connectors, refrain from using tools to

tighten the cable connectors.

4. Prior to securing the cable along its complete length, run the Link Test diagnostics of the management tools

that come with the unit to analyze wireless performance and optimal placement of the outdoor antenna. Use

of this tool is described in the documentation that comes with the radio unit and also can be downloaded from

the Proxim support website at http://support.proxim.com .

5. If required, adjust the direction of the antenna.

6. Once the installation has been fully tested, tighten the nuts of the antenna to lock the antenna into its position.

CAUTION! Avoid over-tightening of the connector, and nuts and screws used to mount the antenna,

to prevent damage to your antenna and radio hardware.

7. Secure the cable along its complete length with cable ties or electrical tape to relieve strain on the antenna

connector properly. No part of any cable should be allowed to hang free. This is especially important for

those parts that are routed outside the building.

8. Proceed as described in the next section to weatherproof all outdoor connectors.

Sealing the Cable Connectors

Most problems associated with wireless outdoor installations are related to degrading performance due to

corrosion of the antenna cable and cable connectors. To avoid this type of problem, you must always seal the

cable connectors that are located outdoors using weatherproofing tape.

You are advised to seal the connectors only after you have verified optimal alignment of the antennas using the

Link Test as described in the documentation that comes with the radio unit. Doing so lets you adjust antenna

placement and cable routing without removing the tape.

To weatherproof the connectors:

1. Prepare the cable and connectors so that they are dry and free from dust, dirt and grease.

2. Attach the tip of the weatherproofing tape to the cable just above the connector. Holding the tape in its

position, now stretch the tape and wind it half-overlapped around the cable and connectors to form a void-free

joint. The degree of stretch may vary in different sections of the joint, as long as the overlaps accomplish a

void-free application.

3. To protect the weatherproofing stretch tape from the effects of Ultra-Violet (UV) radiation (for example, from

direct sunlight), you should protect the joint with two half-overlapped layers of any vinyl plastic electrical tape.

Alternatively, you can apply silicone sealer to protect the weatherproofing tape from sunlight, rain and other

weather conditions.

Grounding the Antenna

Direct grounding of the antenna mast, radio hardware and surge arrestor is extremely important.

Note: A safety grounding system is necessary to protect your radio hardware from lightning strikes and the

build-up of static electricity.

WARNING!

The antenna mast, radio hardware, and surge arrestor must be connected to the same ground, using an

equi-potential bonding conductor.

A good electrical connection should be made to one or more ground rods, using at least a 10AWG

ground wire and non-corrosive hardware.

The grounding system must comply with the National Electrical Code and safety standards that apply in

your country. Always check with a qualified electrician if you are in doubt whether your radio hardware

installation is properly grounded.

Aligning the Antenna

For optimal performance of your wireless link, make sure the antennas are properly aligned (facing one another

eye-to-eye). Antenna alignment is a process to physically align the antennas of both units to have the best

possible radio link established between them. The antenna alignment process usually is performed during

installation and after major repairs.

To align the antennas:

•

Use a pair of binoculars or a map of the area and a compass to point the antennas to one another.

Use the Antenna Alignment Display feature (AAD) to display a measurement of signal quality at the CLI and

serial ports.

•

You also can use the Link Test option of the management tools that come with the MP.11a and the 5054-R

to analyze the radio link quality.

Tsunami MP.11 Antenna Installation

Antenna Alignment Display Feature

Antenna alignment is a process to physically align the antennas of both units to have the best possible radio link

established between them. The antenna alignment process usually is performed during installation and after

major repairs.

The 2454-R and 5054-R have an audible antenna alignment tool that can be activated by plugging in the supplied

serial dongle (supplied with every Base Station) or by issuing the CLI command for antenna alignment. The CLI

command causes both audible and numerical feedback as the CLI shows the running SNR values twice a

second. The model 5054 has the SNR value output on the CLI but not the audible output (see “Antenna

Alignment Commands” on page 21).

The output from the beeper for antenna alignment consists of short beeps with a variable interval. The interval

changes with the SNR level to assist in correctly aligning the antenna. An increase in signal level is indicated by

a shorter interval between beeps; a reduction in signal level results in beeps further apart.

To allow for precise antenna alignment, small changes in SNR result in large changes in the beep period. The

alignment process averages the SNR, which is represented by an average length beep. When a higher SNR is

received, the beep period is made shorter, dependent upon the difference to the average. A lower SNR results in

a longer period between beeps.

The first five steps are represented by a large change and all following steps are a small change. This acts as if a

magnifying glass is centered around the average SNR and the values next to the average are significantly

different.

When the antenna is aimed, the beep can easily be heard if the SNR is rising (shorter period, higher frequency) or

falling (longer period). When the position of the antenna has been changed, the SNR averaging settles at the

new value and the beeping returns to the average length so the antenna can again be aimed towards rising SNR.

Aiming is complete if moving in any direction results in a falling SNR value, which can be heard as longer periods

between beeps.

Notes:

•

Antenna alignment for the Base Station is useful only for a point-to-point link.

The range of the average SNR is limited to values from 0 to 48. Anything over 48 is capped at 48.

AAD is automatically disabled 30 minutes after it is enabled to remove the load of extra messages on the

wireless interface. The default telnet timeout is 900 seconds (15 minutes). If AAD must run for the entire 30

minutes, change the default telnet timeout value greater than 30 minutes (greater than 1800 seconds). This

restriction is for telnet connections only and not for the serial interface. The serial interface never times out.

Link Test

You also can use the Link Test option of the management tools that come with the radio unit to analyze the radio

link quality. The Link Test option lets you display the radio signal strength in relation to the noise in the signal

path. If required, you can interactively optimize the antenna alignment with the Link Test, by making small

modifications in the antenna orientation.

The Link Test provides SNR, Signal, and Noise information.

Link Test stops when you close the Link Test page.

Alternatively, consult a professional Antenna Installation Service to optimize the antenna alignment.

Antenna Polarization

Outdoor antennas are standard-mounted for vertical polarization.

In some cases, you might consider mounting the antenna for horizontal polarization; for example, to minimize the

influence of cross-talk between antennas when:

•

You plan to mount multiple directional antennas to the same mast.

Your wireless link receives interference from a vertically polarized neighboring installation.

Note: For optimal wireless link performance, you must always verify that the antenna polarization on both ends

of the wireless link is the same.

Tsunami MP.11 Antenna Installation

Antenna Cable Routing

The antenna cable must be routed and fixed in such a way that installation technicians have a clear passage

area.

All connectors that are located outdoors must have a weatherproof seal. You are advised to seal connectors only

after you have completed the final radio test.

BEFORE CLIMBING THE ROOF...

Before you start the installation, check whether you have all the required components to set up an outdoor

wireless link.

For each side of a wireless outdoor wireless link you need:

•

One or two low-loss antenna cables or a unit with an integrated antenna

A female-female converter N-connector in case you want to use two antenna cables

Tools and material to mount the antenna

Tape or wraps to attach the antenna cable, for example to the mast

Ethernet cable with waterproof cap for 5054-R

Grounding material such as cable and Faston connector for 5054 or ground-lug plus screw, for 5054-R

If an item is missing or damaged during shipment, inform your supplier.

Chapter 2. Determining Range and Clearance

When you read about wireless outdoor products, you often encounter the terms output power of the radio and

gain of the antenna equipment as measures for the strength of the transmitted signal.

•

Output power of radio equipment often depends on maximum limits as defined by local radio regulations;

consequently, output power is, by definition, not the way to enhance wireless performance.

•

High gain antennas are larger in size than low gain antennas and are characterized by a narrow focus of the

antenna beam. These two characteristics make it more difficult to aim the antennas and adjust antenna

alignment to optimize the performance of the wireless point-to-point link.

The 5054, 2454-R, and 5054-R outdoor solution is based upon the following principles:

•

Output power and antenna gain that comply with the maximum limits as defined by local governing bodies

concerning radio transmissions.

•

Enhanced radio sensitivity for optimal receive quality of radio signals transmitted by remote antennas.

DETERMINING THE OUTDOOR RANGE

The range of your outdoor antenna installation is closely related to a number of different factors. To let you

determine the range of the antenna system in your situation, we have defined the following formula:

Range = Maximum Range x Clearance Factor

where:

Maximum Range

Clearance Factor

Identifies the theoretical maximum that could be achieved under optimal

circumstances using the available Tsunami MP.11 products according to their

specifications and in compliance with local radio regulations.

Identifies a correction value (in percentage) that should be used in case the signal

path of your wireless link does not provide the minimum clearance as listed in the

Maximum Range table. (See “Clearance Factor” on page 24.)

Note: You also can use a calculation sheet provided by Proxim to generate an estimate of link distance and

reliability.

Download from Www.Somanuals.com. All Manuals Search And Download.

Tsunami MP.11 Antenna Installation

Maximum Range

The maximum range of your system is based upon:

•

The type of outdoor antenna equipment

The data speed of the wireless link

The clearance of the signal path (see “Clearance Factor” below).

The values in this section are based upon calculations that assume optimal radio conditions. They do not

represent a guarantee that the same maximum distance can be achieved at your location. Differences in

performance figures can result from:

•

Incorrect alignment of antennas (see “Aligning the Antenna” on page 19)

Polarization mismatch of the antennas

Sources of interference or unexpected reflections in the signal path that affect the communications quality

(see “Antenna Placement” on page 14)

•

Severe weather conditions such as heavy rain or snow fall, or strong winds

Unexpected obstacles in the link path

Seasonal influences such as leaves on trees, or icing on the antennas

Clearance Factor

For optimal performance of your outdoor wireless link, the signal path between the Base Station Unit and

Subscriber Unit must provide sufficient clearance.

Note: An outdoor wireless link that lacks sufficient clearance will suffer from poor performance, which is typically

perceived as slow network response times. Although your radio equipment automatically retransmits

every lost data frame due to an out-of-range situation or frame collision, the larger the number of

retransmissions, the lower the throughput efficiency of your wireless link.

This section explains how to determine the clearance that applies in your environment and (if applicable) the

effect of insufficient clearance on the range of your outdoor wireless link.

In “Chapter 1. Preparing for Installation” on page 7, we described the shape of the antenna beam as being bulged

in the middle.

Figure 3. Fresnel Zone

Download from Www.Somanuals.com. All Manuals Search And Download.

Tsunami MP.11 Antenna Installation

If any significant part of this bulged zone is obstructed, a portion of the radio energy is lost, which can affect the

performance of your wireless link in terms of maximum range and transmit rate.

In Figure 3, you see two variables that determine the shape of the antenna beam, also referred to as Fresnel

Zone:

•

The distance between the antennas (a)

The clearance required for optimal performance (b), where clearance should be interpreted as:

Vertical clearance above the ground and the highest buildings or objects in the signal path

Horizontal clearance from neighboring buildings and objects in the signal path

For optimal range and throughput performance, you must ensure that your antenna installation provides

maximum clearance in both horizontal and vertical direction.

Clearance should be interpreted as follows:

•

In open areas without obstacles in the signal path, clearance is measured as height above the surface of the

earth. For example, if the antenna is mounted on the roof, this height includes the height of the building plus

the height of the mast above the rooftop.

•

In areas with obstacles in the signal path between the two antennas, clearance should be measured as height

above the highest obstacle in the signal path.

In dense urban areas, the clearance should be measured as height above the highest rooftop or any other

obstacles in the signal path between the two antennas.

For situations in which local authorities, the proprietor of the premises, or other factors do not let you set up an

antenna mast that lets you meet the listed clearance requirements, you may be unable to achieve a full line-of-

sight clearance. At the same time, however, when the distance that your wireless outdoor installation must cover

is less than the listed maximum range, you may not even need full clearance.

To determine the effect of insufficient signal path clearance, you must determine the Clearance Factor as

described below, and calculate its effect on the range for your antenna installation using the formula described in

“Determining the Outdoor Range” on page 23.

•

If the clearance for your antenna installation is equal to or better than the minimum clearance requirement,

the Clearance Factor for your installation is 100%.

•

If your actual clearance is less than the minimum clearance, use the diagram depicted in the following figure

to determine the actual range that applies in your situation.

Note: The Clearance Factor Diagram should be used as a rule-of-thumb for estimating the probable range in

case the clearance requirements are not fully met. In real life, using FCC approved products, you will also

find it almost impossible to achieve the level of clearance for maximum range, due to interference from

other radio products.

Tsunami MP.11 Antenna Installation

CALCULATIONS

Availability of the microwave path is a prediction of the percent of time that the link operates without producing an

excessive bit error rate (BER) due to multipath fading. In the absence of direct interference, availability is affected

by the following:

•

Path length

Fade margin

Frequency

Terrain (smooth, average, mountainous)

•

Climate (dry, temperate, humid)

Depending upon the type of information carried over the link and the overall network design redundancy, you may

want to design for a specific availability rate. For example, if the data or voice traffic carried by the radio is critical,

the link can be designed for a very high availability rate (for example, 99.999% or 5.3 minutes of predicted outage

per year).

Availability can be improved by increasing the fade margin either by making the path shorter or by using the

higher gain antennas in conjunction with lower loss antenna cable (using a higher quality antenna cable,

shortening the length, or both).

If the system is intended to operate with “roaming” of Subscriber Units between BSUs, the SU must maintain a

high enough signal level while switching from one BSU to the next. Due to the time necessary to switch, the

coverage (and therefore the distance between the BSUs) is impacted by the speed of movement of the SU or

RSU. The Link Budget of both links between an SU or RSU and either BSU must be high enough to allow good

quality communication and a smooth handover.

Note: In previous 1.x versions of the software in which the SU had a long timeout upon registration, the switch to

a new BSU is made only when the link with the current BSU is lost for at least 30 seconds).

Calculating Received Signal Level and Link Budget

Use the following formula to estimate the received signal level (RSL):

RSL (dBm) = P_out- L₁+ G₁+ G₂- L₂- L_p

where:

P_out

L₁

is the transmitter output power (in dBm)

is the total loss of all transmission elements between the antenna and the RF Unit on one side of

the link (in dB)

G₁

G₂

L₂

is the gain of the antenna on one side of the link (in dB)

is the gain of the antenna on the opposite side of the link (in dB)

is the total loss of all transmission elements between the antenna and the RF Unit on the

opposite side of the link (in dB)

L_p

is the Path loss, defined by:Lp (dB) = 96.6 + 20 log₁₀F + 20 log₁₀D

where:

F is the Frequency of the radio system in GHz (5.8 or 2.4 GHz)

D is the Distance of the path in miles

Note: This formula is available on a calculation sheet provided by Proxim to generate an estimate of link distance

and reliability.

See the following figure for a visual representation of the elements of this equation.

Download from Www.Somanuals.com. All Manuals Search And Download.

Tsunami MP.11 Antenna Installation

Procedure

1. Start with the transmit power and the number of the channel to be used. From the output power tables on

page 30 find the dBm associated with this output power and channel.

2. Subtract the total loss of all transmission elements between the antenna and the radio on one side of the link

(dB).

3. Add the dBi of the antenna you will be using. The total is the EIRP (equivalent isotropically radiated power).

4. Determine your link budget from the Distance and Path Loss table, For example, if the distance between the

two radios is approximately 5 km, the link budget would be 121. (Note that this is the value for 4.8 km, which

is closest to the actual value.)

5. Add the gain of the antenna on the second side of the link.

6. Subtract the total loss of all transmission elements between the antenna and the radio on the second side of

the link. The result is the Received Signal Level (RSL).

7. From the Receiver Sensitivity tables in the Tsunami MP.11 Installation and Management manual Technical

Specifications, find the dBm value for the data rate used for the link.

8. Subtract this value from the Received Signal Level; this is the Fade Margin.

Download from Www.Somanuals.com. All Manuals Search And Download.

Tsunami MP.11 Antenna Installation

Notes:

•

The RSL must be higher than the Receiver Sensitivity plus the fade margin for a good link. See Table 1 to

have a working link with no excessive errors. The amount of Fade Margin indicates the reliability of the link;

the more Fade Margin, the more reliable the link.

•

The path loss must be smaller than the link budget minus the minimum required fade margin. The maximum

ranges cause the path loss plus the fade margin to be the same as the link budget.

The results of this link budget calculation are very important for determining any potential problems during

installation. If you have calculated the expected RSL, you can verify that it has been achieved during installation

and troubleshooting, if necessary.

In the USA and Canada, this model radio can be installed with any gain directional antennas, as there is no

Effective Isotropic Radiated Power (EIRP) limit for the application of these systems for fixed point-to-point

applications in the 5.8 GHz frequency band. In other bands and in other countries, EIRP limits may apply.

In the case of EIRP limits, use the lesser of either (P_out- L₁+ G₁) or the EIRP limit within the previous equation.

You should check this equation in both directions to assure legal application. An EIRP limit is the maximum RF

energy that can be transmitted, as measured at the transmitting antenna, and is usually determined by

government regulations.

Proxim’s recommendation is to keep at least 60-70% of the first Fresnel zone free. If the clearance is lower than

this percentage, the link budget and achieved fade margin are affected. Clearances more than 100% of the

Fresnel zone can cause reflections that are 180 degrees out of phase and can cancel out the signal. The Fresnel

zone works in both the horizontal and vertical paths.

The first Fresnel zone size is a list; Proxim’s recommendation is to keep at least 60-70% of this zone free. If the

clearance is lower than this percentage, the link budget and achieved fade margin are affected. Clearances more

than 100% of the Fresnel zone can cause reflections that are 180 degrees out of phase and can cancel out the

signal. The Fresnel zone works in both the horizontal and vertical paths.

Tables for output levels can be found in the Technical Specifications in the Tsunami MP.11 Installation and

Management manual.

Chapter 3. Antenna Cabling System

INTRODUCTION

As radio regulations differ between the various countries worldwide, not all of the outdoor solutions described in

this manual may be allowed in the country where you plan to install this equipment.

Local radio regulations or legislation may impose restrictions on the use of specific combinations of:

•

Low-loss antenna cables and outdoor antennas

Radio channels selected at the units that are connected to specific outdoor antennas

Note: A basic rule for selecting a combination of cables and antennas is that no combination is allowed unless

explicitly approved in this manual. Therefore, always use this chapter in combination with “Chapter 2.

Determining Range and Clearance” on page 19 of this document to select the right type of antenna

equipment and to inform your antenna installer and LAN administrator about the impact of regulatory

constraints on their job or activities.

CABLE COMPONENTS

To comply with local radio regulations, the BSUs and SUs have a selectable radio power output level. It can be

selected through the TPC (Transmit Power Control) parameter in the user Interface. See the product’s

Installation and Management manual for more information.

The low-loss antenna cable recommended is an LMR-600 (2 meters / 6 feet). You can order this accessory from

Proxim Wireless Corporation.

When you order the antenna equipment, make sure that you order cables that comply with the regulations that

apply in your country. In case of doubt, consult the Proxim Wireless Corporation Sales office for more information

To connect your radio hardware to an outdoor antenna installation, you will need the following cabling

components:

•

Surge arrestor

Low-loss antenna cables

One of the outdoor antennas described in Tsunami MP.11 Recommended 5 Gz and 2.4 GHz Antennas.

When purchasing new MP.11 products, each of these components will be equipped with standard N-type

connectors.

When ordering separate components, for example as a spare part or replacement to previously purchased

outdoor antenna equipment, carefully read the note on the following page to ensure that you order components

with an N-type connector that matches the other parts of your outdoor antenna cabling system.

SELECTING THE CORRECT CONNECTOR TYPE

The following are differences between the Tsunami MP.11 Model 5054 and Model 5054-R:

•

Male versus Female N-type connector

Indoor install and long coax versus Outdoor install and short coax

Low-loss antenna coax versus outdoor-rated Ethernet cable and surge arrestor

All cabling components of the outdoor antenna system come with standard-N type connectors as depicted in the

following table.

C Low-loss cable

D Outdoor antenna

Note that the gender of the connector is not determined by the connector’s thread, but by its center pin; a solid

center pin = male, a hollow pin = female.

DANGER!

Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic discharges

that may occur at the antenna (for example a lightning strike during thunderstorms) may damage your

electronic equipment and cause personal injury or death to persons touching the exposed metal

connectors of the antenna cable.

To avoid damage and personal injury, the entire antenna cabling system must be grounded at all times.

When installing, disconnecting or replacing one of the cabling components, you must ensure at all times

that each exposed metal connectors of the antenna cabling system will be grounded locally during the

work.

When mounting or replacing the surge arrestor:

1. First connect each of the connectors of the low-loss antenna cables to the grounding system.

2. Next connect the cable connector to the grounding system.

3. Finally connect the surge arrestor to the grounding system.

Before you proceed, verify that each of the items is properly grounded and that the ground will not be interrupted

when disconnecting one of the antenna system components.

Check with a qualified electrician if you are in doubt as to whether the surge arrestor and cable connectors are

properly grounded. Only after you have verified that each of the items is properly grounded, replace the surge

arrestor and disconnect the cables from the grounding system in exactly the reverse order of the previous steps.

USING A SURGE ARRESTOR

Lightning protection is used to maximize the reliability of communications equipment by safely re-directing current

from a lightning strike or a power surge traveling along the Cat 5 Ethernet cabling to ground using the shortest

path possible. Designing a proper grounding system prior to installing any communications equipment is critical

to minimize the possibility of equipment damage, void warranties, and cause serious injury.

The surge arrestor (sometimes referred to as a lightning protector) can protect your sensitive electronic

equipment from high-voltage surges caused by discharges and transients at the antenna.

Proxim Wireless offers provides superior lightning and surge protection for Tsunami MP.11 and Tsunami

QuickBridge.11 products. See the following sections for more information.

CAUTION!

To avoid damage to electronic equipment and your radio equipment, always apply the surge

arrestor between the outdoor antenna installation and the radio hardware or other

computing device that is connected to the outdoor antennas.
