Packet Radio TDM
The evolution of microwave radio from TDM to packet
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 these investments in less than two years,
as a result of OPEX savings
• Minimized OPEX, despite capacity increases —
which 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
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
many kinds of incoming traffic,
including 2G, 3G and WiMAX. High
perfor mance and low latency for each
service and synchro nization of these
services is achieved along the entire
backhauling network.
Service-Aware Transport
The Alcatel-Lucent 9500 MPR
supports adaptive packet transport
for exceptional use of radio fre quency
spectrum and a dramatic improve-
ment in broadband traffic transmis-
sion. Our service-aware feature
directly maps all traffic, both
guaranteed and broadband, over the
radio frame. It recognizes the traffic
types in the incoming packets and
automatically adapts to varying
microwave link conditions. For
instance, priority 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.
Simplified Growth
Because the Alcatel-Lucent 9500
MPR offers service-aware transport,
you can increase the number of
active users without the hassle of
transport constraints. This system
allows a dramatic increase in the
number of broadband users — up
to one hundred times that of E1-
or T1-based TDM solutions. You also
gain enhanced support for high-
bandwidth applications, such as music
downloading and streaming video.
