Zusammenfassung:	A participant response system (50) comprises at least one host computer (52) and a plurality of remote units (62) communicating wirelessly with the host computer using a radio packet protocol. During communications between the host computer (52) and the remote units (62), data messages from the host computer (52) to be processed by substantially all of the remote units (62) are transmitted to the remote units in general broadcast frames (BF) destined for all of the remote units and data messages from the host computer (52) to be processed by selected ones of the remote units (62) are transmitted to the selected ones of the remote units in message frames destined for those selected ones of the remote units (62) outside of the period of each general broadcast frame. Data messages from remote units (62) destined for the host computer (52) are also transmitted in message frames beyond the period of each general broadcast frame.
