Abstract
A method and apparatus for revising and minimizing renegotiations of a data transfer rate for wireless-capable modems transceiving data over a wireless communication channel via a wireless transceiver. When a wireless-capable modem presents a favorable signal-to-noise ratio resulting from a stationary or near stationary position, higher data transfer rates are employed for data exchange. When varying signal-to-noise ratios are detected designating mobility of the wireless-capable modem, then a reduced mobility data transfer rate is employed to provide a sustained data transfer rate for the duration of the mobility without oscillating between differing data transfer rates thereby incurring the significant renegotiation down-time due to fluctuating signal quality. The mobility detection and reduction in the data transfer rate to a more reliable level during mobility is performed automatically without user intervention.
