Abstract
Methods of processing wireless communication include providing at least one interrogator configured for transmitting and receiving wireless communication data. A plurality of identification devices are provided and are configured for receiving wireless communication data transmitted by the interrogator. Responsive to receiving such communication data, the devices are capable of generating and transmitting a reply back to the interrogator. Preferably, transmitted replies are delayed for different determinable amounts of time which enables the interrogator to detect multiple replies. In a preferred implementation, the wireless communication is radio frequency communication. In another preferred implementation, each device is capable of calculating its own delay utilizing a random value generator. Related system circuitry is described.
