1. An audience response system comprising:
- a plurality of response units, each response unit including;
a transceiver,an address, andlogic configured to receive a user selection and, without receiving a wireless signal to initiate transmission, instruct the transceiver to wirelessly transmit a plurality of selection signals, each of the plurality of selection signals encoding the address and the user selection; and
a base unit including a transceiver configured to wirelessly receive at least one of the plurality of selection signals and wirelessly transmit an acknowledgment signal in response to the receipt.

Abstract
A wireless communication system is disclosed herein. The wireless communication system may include transmitter units and a receiver. In one embodiment, each transmitter has an address and logic programmed to perform the steps of receiving a user selection and, responsive to the receiving, repeatedly transmitting a wireless selection signal until a wireless acknowledgment signal is received. The wireless selection signal may include the address and the user selection. The receiver may include means to receive a wireless selection signal and logic programmed to transmit a wireless acknowledgment signal in response to the receipt of each wireless selection signal.

15. A method for wirelessly receiving data representing audience responses in an audience response system having a plurality of response units and at least one base unit, the method comprising:
-
initiating a start up sequence; entering a non-transmission mode upon completion of the start up sequence; remaining in the non-transmission mode until a wireless signal having data representing a user response and data representing an address is wirelessly received; decoding the wireless signal into data representing the user response and data representing the address; generating an acknowledgment signal encoding the data representing the address; and wirelessly transmitting the acknowledgment signal. - View Dependent Claims (16, 17, 18, 19)
