A method for communicating to a recipient transceiver from a plurality of transceivers located within the broadcast range of the recipient transceiver includes: transmitting a communication at a first power level such that only a first group of transceivers receive the broadcast, the communication including a command causing each of the first group of transceivers not to respond to a subsequent broadcast; and subsequent thereto, transmitting a communication at a second power level greater than the first power level such that a second group of transceivers greater than and including the first group of transceivers receive the broadcast, but such that only a limited number of transceivers of the second group respond to the broadcast, the limited number of transceivers excluding the first group of transceivers. Each of the plurality of transceivers is associated with a respective sensor for acquiring data and transmitting the data to the recipient transceiver.
