Streamlined, cost-effective
microwave IP transformation
Meeting a key backhaul challenge –
the rapid growth of multimedia traffic
To remain competitive in the rapidly
changing mobile marketplace, operators
need to deliver profitable new services
while reducing backhaul costs. Users
are expanding their demands beyond
basic voice and data services like instant
messaging and email; they want more
delay-sensitive applications, such as
media streaming and real-time multi-
media. To support these services,
broadband wireless technologies,
including High-Speed Download
Packet Access (HSDPA) and EVDO,
are providing higher transmission
speeds and packet interfaces.
However, backhaul networks must
also evolve to meet these new band-
width demands at acceptable cost
points. IP transport offers a valuable
solution to help operators transform
networks and better manage growing
broadband traffic.
the connectivity of Ethernet and
legacy T1 base stations. As a result,
the network can easily and efficiently
accommodate rapid growth in
multimedia traffic, with smooth
migration from TDM to IP.
Native transport of packet traffic
produces a clear gain in scarce radio
resources; while packet solutions can
absorb TDM traffic efficiently, TDM
solutions cannot handle packet
traffic cost-effectively.
The Alcatel-Lucent 9500 MPR offers
a revolutionary way of transporting
packets natively. Using an innovative
approach to deliver the quality of
service required for each traffic type
dramatically reduces operating
expenditures (OPEX) and improves

The need for IP transformation
The growing demand for new
The evolution of microwave radio from TDM to packet
broadband services requires more
connectivity and additional ports
at cell sites. Packet traffic growth
drives bandwidth requirements
higher (20 Mb/s to 30 Mb/s per cell
site); it also has different capacity and
quality constraints than voice traffic
technologies enables data-aware transport, which can
support new high-bandwidth services while leveraging
existing technologies. IP transformation typically seeks
to achieve four major goals:
• Gradual transformation of the network, focusing on areas
where compelling events force investment in a solution
• Return on investment in less than two years (as a result
of OPEX savings)
As mobile network infrastructure
evolves, IP-native base stations will
have Ethernet interfaces rather than
T1. This change in physical interface
brings new challenges to backhaul
networks. Because the transition
will not happen overnight, backhaul
networks must migrate gracefully while
supporting a mixed payload of legacy
TDM and growing packet traffic.
• Minimized OPEX despite capacity increases; requires
optimizing the use of scarce resources and aggregating
all services over a single pipe, with no overlays
• Use of a multi-vendor model with standard protocols
and no proprietary equipment
Data traffic is growing fast, but revenues are not increas-
ing at the same pace; this creates a need to find more
efficient ways to transport the additional packet traffic

An innovative, truly packet product
The Alcatel-Lucent 9500 MPR helps
ensure optimal performance for all
types of backhauling technologies and
enables smooth evolution of existing
TDM-based networks to an all-IP
network. It aggregates any kind of
incoming traffic, including Second
Generation (2G), Third Generation
(3G) and WiMAX. Performance
and low latency are improved for
each service, and synchronization
can be achieved along the entire
backhauling network.
traffic, such as video and voice, are
assigned to the most available packets
across the radio link, while less time-
dependent applications, such as
Internet browsing and e-mail, are
given access based on availability;
this is shown in Figure 3.
simplified growth
Because the Alcatel-Lucent 9500 MPR
offers service-aware transport, operators
can increase the number of active
users without the inefficiencies of
transport constraints. This system
enables a dramatic increase in broad-
band users on the network; up to one
hundred times that of T1-based TDM
solutions. Operators also gain enhanced
support for high-bandwidth applica-
tions, such as music downloading
and streaming video.
service-aware transport
The Alcatel-Lucent 9500 MPR supports
adaptive packet transport for excep-
tional use of the radio frequency (RF)
spectrum and a dramatic improvement
in broadband traffic transmission.
This service-aware feature directly
maps all traffic, both guaranteed and
broadband, over the radio frame. It
recognizes the traffic types in each
incoming packet and automatically
adapts to varying microwave link
conditions. For instance, priority
As shown in Figure 4, packet solutions
support more active voice and multi-
media users than TDM solutions.

outdoor Unit
extending IP/MPLs from the core to the cell site
This same Outdoor Unit (ODU) is available for the whole
product family (both traditional TDM and IP microwave
solutions), allowing smooth migration from TDM to packet
networks and protecting your initial investment.
The Alcatel-Lucent 9500 MPR platform is part of an
integrated end-to-end remote access network and core
solution for complete IP transformation. Comprehensive
monitoring of the entire IP remote access network helps
ensure effective IP/Multi-Protocol Label Switching
(MPLS) management and reduces complexity.
The Alcatel-Lucent 9500 MPR is transparent to all
microwave solutions, so it can be deployed in any existing
network. This offers seamless, cost-effective evolution
from TDM to packet transport — on the schedule that
best meets your needs.
Key components
To integrate TDM, IP and microwave technologies, the
Alcatel-Lucent 9500 MPR platform includes three main
components.
The Microwave service switch
The Microwave Service Switch (MSS) can aggregate
any kind of TDM traffic with any kind of packet traffic
over a single Ethernet connection. Different services
can be dynamically managed, depending on the existing
radio performance levels, particularly in the case of
fading conditions.

Microwave Packet Transport Unit –
High Capacity, Long Haul
The Microwave Packet Transport Unit — High Capacity,
Long Haul (MPT-HL) simplifies the critical part of a
microwave system, using the latest RF and modem tech-
nology. It provides two RF slots in 2.5 rack units of space
in 1+0, 1+1 Space Diversity/Frequency Diversity (SD/FD),
and 2+0 installations. Connection to the MPT-HL from
the MSS is simplified to a standard Gigabit Ethernet connec-
tion. The MPT-HL is the first all-packet, all-indoor nodal
microwave transmission system.
