    Abstract: A wireless communication system and method includes providing at least one master unit and a plurality of slave units communicating with the at least one master unit over at least one wireless communication link. The at least one master unit sends polling signals to the slave units over the at least one wireless communication link. The slave units send data to the at least one master unit over the at least one communication link in response to one of the polling signals. The communication link is made up of at least one master transceiver at the at least one master unit and a plurality of slave transceivers each at one of the slave units. The at least one master transceiver and the slave transceivers communicate with a spread-spectrum hopping protocol.

    Abstract: A response system and method of retrieving user responses from a plurality of users includes providing a plurality of base units and a plurality of response units, each of the response units adapted to receive a user input selection and to communicate that user input selection with at least one base unit utilizing wireless communication. Personality data is provided for the response units. The personality data facilitates communication with a particular base unit. The personality data of a particular one of the response units is changed in order to change which of the base units that response unit communicates. This allows a response unit to become grouped with a particular base unit at a particular time and become grouped with another base unit at another particular time. The personality data may be obtained from a database.
