A drive module that includes a housing, first and second axle shafts, a differential assembly, a propulsion motor, a brake element fixed to the housing, a torque-vectoring transmission and a mode gear. An ad-hoc master is selected from the virtual power-line network-controllers. Thus, by allowing the base station to change the data rate more frequently than the individual wireless units reports the rate information, the rate adaptation system can provide improved flexibility and more efficient use of wireless resources while reducing the processing and transmission overhead required to report the rate information. Under broadcast control, local computers, combine user information selectively into prior art communications to exhibit personalized mass media programming at video monitors, speakers, printers, etc.
