RKF Engineering is the system engineering team for the Terrestar networks developing requirements and providing technical oversight for their terrestrial and satellite network.  Terrestar is planning a nationwide 4G network with cellular sized terminals that switch seamlessly between satellite and  terrestrial networks. The satellite has been launched and can generate with the ground based beamformer up to 550 beams over Canada and the US. RKF responsibilities in relation to the TerreStar network include:

Space & Terrestrial Radio Network        (Requirements and designs) Link, Coverage and QOS Analyses Air Interface Definition, tradeoffs and roadmap Satellite Beamforming Terminal design/requirements Spectrum Regulatory support Satellite monitoring and testing

For the TerreStar handset RKF performed technical oversight, chipset definition, requirements definition, smart antenna design and modeling & simulation of antenna link performance combined with satellite protocols.

RKF performed trade studies, designed simulations, developed requirements and provided technical oversight of the Terrestar network.  RKF designed simulation models to predict the performance of both satellite and terrestrial Access and Non-Access stratums.  These models included terrestrial cell deployment along with satellite beam laydowns.  The modeling and simulations took many factors into account including:

As a separate contract, RKF developed the GRM, a resource optimization tool operating in the Terrestar NCC.
