Secure Communications 1. The network employs the IMBE (Improved Multi-Band Excitation),voice codec approved by The Association of Public Safety Communications. 2. Digital coding and scrambling prevents casual eavesdropping or monitoring of calls.
Features and Benefits 1. Seamless coverage 2. Satellites act as one big radio tower for all of North America. 3. Users don't have to worry about service interruptions associated with roaming because it is all one network .
