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.
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
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.
As shown in Figure 4, packet solutions
support more active voice and multi-
media users than TDM solutions.
