Abstract
A wireless response system includes at least one base unit and a plurality of response units. The at least one base unit has a wireless receiver for receiving wireless signals over a plurality of wireless communication channels. Each of the communication channels differs from the other of the communication channels. Response units have a wireless transmitter for asynchronously transmitting the wireless signal to the at least one base unit over one of the plurality of communication channels. The at least one base unit may include a plurality of base units and a computer system including a communication system for retrieving user selections from the base units. The user selections may be retrieved from the response units by base units that are capable of receiving the wireless signals.
