network topology  
A wireless Local Area Network (LAN) uses a wireless adapter to connect each  
computer to the network. Computers in a wireless network must be configured to  
share the same radio channel.  
The Wireless USB Network Adapter provides wireless computers access to a wired  
network. This integrated wireless and wired network is called an “infrastructure”  
configuration. A group of wireless-network-adapter-equipped computers plus a  
wireless access point, such as the HP Wireless Network Access Point, is called a  
Basic Service Set (BSS). The wireless access point connects the wireless network to  
the conventional wired network. Each wireless-network-adapter-equipped computer  
can communicate with any computer in a wired network infrastructure via the  
wireless access point.  
An infrastructure configuration doubles the effective wireless transmission range of  
two wireless-network-adapter-equipped PCs since the wireless access point  
forwards data within the network. It is essential to use a unique ID, a BSSID or,  
more generically, an SSID within a wireless network. All PCs within an independent  
wireless network that are configured without roaming options (see Roaming below)  
must be configured with the same wireless network ID.  
The wireless network infrastructure configuration is appropriate for enterprise-scale  
wireless access to a central database and for mobile users.  
roaming  
Infrastructure mode also supports roaming capabilities for mobile users. A multiple  
wireless network can be configured as an “extended” wireless network, known as  
an Extended Service Set (ESS), allowing users to roam freely within it. All wireless-  
network-adapter-equipped PCs within one extended network must be configured  
with the same extended network ID an ESSID or taken generically with a BSSID as  
discussed above, called an SSID, and must use the same radio channel.  
Before enabling an extended wireless network with roaming capability, select a  
feasible radio channel and an optimal location for the wireless access point. Proper  
wireless access point positioning and a clear radio signal will enhance  
performance.

wireless FAQs  
Can I run an application from a remote computer over the wireless network?  
This depends on whether the application is designed to be used over a network.  
Consult the application’s documentation to determine if it supports operation  
over a network  
Can I play computer games with other members of the wireless network?  
Yes, as long as the game supports multiple players over a local area network  
(LAN). Refer to the game’s documentation for more information.  
What is the IEEE 802.11 standard?  
The IEEE 802.11 Wireless LAN Standards Subcommittee of the Institute of  
Electrical and Electronics Engineers (IEEE) is formulating a standard for the  
industry to enable wireless LAN hardware from different manufacturers to  
communicate with one another.  
What IEEE 802.11 features are supported?  
HP wireless products support the following IEEE 802.11 functions:  
CMSA/CA plus the Acknowledge protocol  
Multi-channel roaming  
Automatic rate selection  
RTS/CTS  
Fragmentation  
Power management  
Would information be intercepted while transmitting on air?  
Wireless LAN features two-fold security protection. On the hardware side, as  
with DSSS technology, it has the devices have the inherent scrambling security  
feature. On the software side, wireless LAN offers Wired Equivalent Privacy  
(WEP) encryption to enhance security and access control.

each device senses whether the line is idle and then sends data. If another  
device sends data at the same time, a collision occurs, the data is discarded,  
and the devices try again.  
default gateway  
The router used to forward all traffic not addressed to a station within the local  
subnet.  
DHCP (Dynamic Host Configuration Protocol)  
A utility for assigning TCP/IP addresses to workstations automatically (a unique  
IP address must be assigned to each computer in the network). When computers  
are moved within the network, DHCP allows automated IP addresses to be  
assigned automatically. DHCP “leases” an IP address to a device for a specific  
amount of time, which is useful in education and other environments where  
users change frequently. DHCP also supports static IP addresses for computers  
needing a permanent IP address, such as those containing Web servers. See  
DCHP Client  
A device configured to receive a DHCP address.  
DHCP Server  
A device configured to assign IP addresses to DHCP clients.  
DMZ (Demilitarized Zone)

glossary  
DNS (Domain Name System)  
Method for matching Internet domain names with IP addresses. When a  
Uniform Resource Locator (URL) is entered into a Web browser, a domain name  
server retrieves the corresponding IP address for the domain name specified  
(“name resolution”) and sends the request to the appropriate server. Domain  
names are convenient “handles” for IP addresses.  
DSL (Digital Subscriber Line)  
Transmits data bi-directionally at high speeds.  
DSSS (Direct Sequence Spread Spectrum )  
Generates a redundant bit pattern for each bit to be transmitted. This bit pattern  
is called a chip (or chipping code). The longer the chip, the greater the  
probability that the original data can be recovered. Even if one or more bits in  
the chip are damaged during transmission, statistical techniques embedded in  
the radio can recover the original data without the need for retransmission. To  
an unintended receiver, DSSS appears as low-power wideband noise and is  
rejected (ignored) by most narrowband receivers.  
dynamic IP address  
An IP address that is automatically assigned (typically by a DHCP server) in a  
ESS (Extended Service Set)  
More than one wireless network.  
ESSID (Extended Service Set Identification)  
A unique name (or ID) used by users roaming among the multiple wireless  
networks. An infrastructure configuration can support roaming capability for  
mobile workers. More than one BSS can be configured as an ESS. Users within  
an ESS can roam freely between BSSs while served as a continuous connection  
to the network. Wireless stations and wireless access points within an ESS must  
be configured with the same ESSID and radio channel.

single logical channel. To an unintended receiver, FHSS appears to be short-  
duration impulse noise.  
firewall  
A set of related programs, located at a network gateway server, that protects  
the resources of a network from users in other networks. It also controls access  
of internal users to outside resources. A firewall, working closely with the
