Abstract:
In a data communication system employing a wireless-capable modem transceiving data at a determined data transfer rate via a wireless transceiver, a method for revising and minimizing renegotiations of said data transfer rate when variations to the mobility of said wireless-capable modem are detected, said method comprising the steps of:a) executing a mobility detection process to determine variations to a signal-to-noise ratio (SNR) of said data received by said wireless-capable modem;b) when said variations to said SNR exceed a mobility threshold, revising said data transfer rate from a stationary maximum data transfer rate to a mobile default data transfer rate to provide a sustained SNR during mobility of said wireless-capable modem; andc) when variations to said SNR do not exceed said mobility threshold, revising said data transfer rate to said stationary maximum data transfer rate capable by said wireless-capable modem.
