Alvarion believes that compliance with standard-driven open architecture protects
the infrastructure investment, and opens the system to a variety of fully
interoperable end-user devices. As such, 4Motion is designed with open
architecture and interfaces according to the WiMAX Forum networking working
group (NWG) profile C, which supports openness and enables flat as well as
hierarchical topologies. In addition, by keeping the radio resource management
functionality in the Base Transceiver Station only, Profile C delivers a faster,
optimized handover mechanism.
