Abstract:
1. A wireless data transmission method comprising: providing a plurality of radio frequency transmitters; providing a plurality of receivers to receive transmissions from the transmitters; configuring each of the receivers to receive the transmissions on a respective one of a plurality of frequency channels; defining a data format including a plurality of transmission time slots; causing each of the transmitters to independently select one of the time slots and one of the frequency channels; and using the transmitters to transmit the transmissions to the receiver in the independently selected time slots and the independently selected frequency channels, wherein, if at least two of the transmitters conflict by transmitting the transmission in a same one of the independently selected time slots and in a same one of the independently selected frequency channels, the method comprises the further step of using the conflicting transmitters to re-transmit the transmissions to the receiver, and wherein the method comprises the further step of transmitting acknowledgement codes from the receiver to non-conflicting ones of the transmitters.
