2.1 Purpose and Function

The 9500 Microwave Packet Radio (MPR) is a microwave digital radio that supports PDH, SDH and
packet data (Ethernet) for migrating to IP. The 9500 MPR-E provides a generic, modular IP platform for
multiple network applications (including 2G/3G/HSDPA/WiMAX backhauling to Metro Ethernet areas) to
accommodate broadband services. The 9500 MPR-E radio family supports low, medium, and high
capacity applications using European data rates, frequencies, channel plans, and tributary interfaces.
– TDM/PDH Data Rates: E1
– SDH Data Rates: STM-1
– ATM Data Rates: E1
– Ethernet Data Speed: 10, 100, 1000 Mb/s
– RF Frequency Range: 6 to 38 GHz

2.1.1 Innovative solutions

The 9500 MPR-E innovative solutions mainly are:
[1] Multiservice aggregation layer: the capacity to use Ethernet as a common transmission layer to
transport any kind of traffic, independently by the type of interface. Ethernet becomes the conver-
gence layer.
[2] Service awareness: traffic handling and quality management, queuing traffic according to the type
of service assigned, independently by the type of interface
[3] Packet node: no service aggregation limits with all traffic aggregated in packets, in term of: capacity,
type of service requirements and type of interface
[4] Service-driven adaptive modulation: fully exploit the air bandwidth in its entirety by changing mod-
ulation scheme according to the propagation availability and allocate transport capacity, discrimi-
nating traffic by different services, only possible in a packet-based environment.
