A method for providing service levels in a Radio Frequency (RF) network is disclosed. The method including: associating one or more service levels with each supported symbol rate, modulation and error correction encoded scheme (ModCod); assigning a subscriber service level for a RF transmitter; receiving a signal quality of a transmission by the RF transmitter; selecting a transmit ModCod from the supported ModCods, wherein the signal quality exceeds a threshold signal quality for the transmit ModCod; and authorizing the RF transmitter to transmit to the receiver when the subscriber service level is included in the one or more service levels associated with the transmit ModCod, wherein signal quality adapts to a signal fade.

Method and system for offering subscriber service plans by adaptive coding and modulation used

A computer for a communications terminal includes a memory and a processor. The computer is programmed to identify a spectrum analysis test triggering event. The computer specifies a set of test parameters that include a test frequency range. The computer further sets a receiver to receive sequentially a plurality of signals. Each signal is received in one of a plurality of frequency bands within the frequency range. The computer measures, via the receiver, at least one characteristic of the signal received in each frequency band.

A mobile terminal for satellite communications receives communication, e.g., from a gateway via a satellite link. A frequency lock loop unit locks to the carrier frequency of the received communication. The mobile terminal includes a global positioning system for receiving global positioning data. The mobile terminal determines the Doppler frequency shift of the received communications based on the global positioning data. The mobile terminal generates a reference clock for return transmissions based on the frequency of the frequency lock loop, corrected for the Doppler shift. A correction factor of two times the determined Doppler frequency shift is used, to compensate for both a forward and return transmission link.
