The PROPSIM MANET Channel Emulation Solution secures end-to-end performance and interoperability of Mobile Ad-Hoc Networks (MANET) and mesh radio systems (a self-forming and self-healing reliable network that eliminates single points of failure) for tactical mission critical wireless communications. Ensuring the robust inter-operation of avionics, surveillance, radar, or satellite systems for mission critical wireless communications, manufacturers and military forces require the ability to test mixed networks that combine tactical and avionics radios with satellite links. Increased complexity and technological advancements, such as MIMO and beamforming in wireless military communication systems, have accelerated the need to test large mesh-network topologies with dynamically changing radio channel and interference conditions. This new solution enables users to easily replicate field-testing conditions in a repeatable way. The PROPSIM MANET Channel Emulation Solution is a highly scalable and flexible solution that supports full mesh configurations of up to 64 radios using 4032 independent fading channels in a single unit for testing large SISO and MIMO mesh-network topologies; up to 1.2 GHz of instantaneous bandwidth for ultra-wideband support for testing gigabit links; and easy-to-use interface for dynamic scenario creation and for accessing all key radio channel parameters.
