Microwave Packet Radio
(North American Markets)
Streamlined, cost-effective
microwave IP transformation
Alcatel-Lucent 9500 Microwave Packet Radio North American Markets2
The Alcatel-Lucent 9500 Microwave Packet Radio (MPR)
enables smooth transformation of backhaul networks from
TDM to IP, providing efficient transport of multimedia traffic
while supporting legacy TDM. It improves packet aggregation,
increases bandwidth, optimizes Ethernet connectivity, and
delivers the quality of service needed to satisfy end users.
The Alcatel-Lucent 9500 MPR allows mobility, utility and
public service providers to efficiently accommodate rapid
growth in data and multimedia traffic because packets are
handled natively and transmission is adapted to the propagation
conditions and quality required by different types of services.
