Mobile data telephone.

摘要

A mobile data telephone (100) capable of transmitting and/or receiving voice and/or data signals over cellular communication channels or other air interfaces comprises a radio (101) transceiver and a data modem (102) in the same physical package. The transceiver and the modem have their respective controllers (111, 117 resp.) coupled so that they are effectively linked to achieve control of data transfer therebetween. In response to communication channel conditions in the air interface, the data flow between the modem and an audio processor (108) of the transceiver can be selectively altered yielding high performance and high quality data transfer rates in the presence of severe channel impairments. <IMAGE>
