Abstract
A narrowband communication system provides wideband data services in a secondary service band. This limits the impact on primary services in peak traffic regions in that the primary service band is not required to download wideband data from a communication node (e.g., a satellite) to a mobile terminal. The narrowband communication system implements a handoff protocol ( ) that rate negotiates a channel bandwidth of an active connection ( ) to the amount of channels that are available in a new cell. The narrowband communication system preempts ( ) lower priority subscribers when a higher priority ( ) high-speed data terminal requires access to the system and a requested channel assignment is not available ( ). The complexity of a high-speed data terminal communication chipset is reduced by a receiver design that minimizes the range of frequencies that are required to be demodulated.
