ABSTRACT:
A wireless response system and method of receiving user responses from a plurality of users at a base unit includes providing a base unit having a base transceiver that is adapted to wireless signal transmitting and wireless signal receiving and providing a plurality of response units. Each of the response units includes a response unit transceiver and a user input device. The response unit transceiver is adapted to wireless signal transmitting and wireless signal receiving. User input selections are received with the user input device. A response user transmission is transmitted with the response unit transceiver in response to the user input device receiving a user input selection. A base transmission is transmitted with the base unit transceiver. The user response transmissions are asynchronously transmitted after receipt of a base transmission.
