[. . . ] Alcatel-Lucent 9500 Microwave Packet Radio (ETSI Markets) The Alcatel-Lucent 9500 Microwave Packet Radio (MPR) provides cost-effective IP transformation for seamless microwave transport of TDM, ATM, IP and Ethernet traffic over a Carrier Ethernet infrastructure. The steady increase of data services in backhaul networks results in high capacity and costs if addressed with traditional TDM or hybrid microwave systems. [. . . ] Asmobile-networkinfrastructureevolves, IP-nativebase stationswillhaveEthernetinterfacesinsteadofE1orT1 interfaces.

This allows sharing of a common packet-transmission infrastructure, regardless of the nature of the traffic carried. Mapping of different access technologies over Ethernet is achieved with standardized protocols. A single transmission pipe is used for all services and access technologies on cell sites. In contrast, TDM radio stacks multiple data streams (E1, Ethernet) over the radio channel and underutilizes a large portion of the bandwidth.
