Overview of the Cisco MWR 1900 Router
The MWR 1900 Mobile Wireless Edge Router is a networking platform optimized for use in mobile
wireless networks. It extends IP connectivity to the cell site and Base Transceiver Station (BTS), and
through a Fast Ethernet interface to the BTS, provides bandwidth-efficient IP transport of voice and data
bearer traffic, as well as maintenance, control, and signalling traffic, over the leased line backhaul
network between the BTS and leased line termination and aggregation node via compression
(cRTP/cUDP) and packet multiplexing (PPPmux and MLPPP). It supports a limited set of interfaces and
protocols, but offers high performance at a low cost while meeting the critical requirements for
deployment in cell sites, including small size, extended operating temperature range, high availability,
and DC input power flexibility.
