Abstract
A wireless response system and method of retrieving user selections includes providing a plurality of response units, each having a wireless response transceiver and an input device and a plurality of base units, each having a wireless base transceiver. The wireless response transceiver is adapted to transmitting a response transmission in response to receipt of a base transmission. The base transceiver is adapted to transmitting base transmissions and receiving response transmissions from the response units. Each of the base units and each of the response units are assigned communication identification. Base transmissions include a unique base address of the base unit transmitting that base transmission. Response transmission includes the base address of the base transmission to which that response transmission is responding. Each of the base units processes response transmissions having its base address and does not process response transmissions not having its base address.
