1. An apparatus comprising:
- a receiver to receive a security query transmitted according to a wireless communication standard through a first wireless channel, the first channel being a dedicated security channel, the security query comprising a data item identifying a wireless communication system and a first power level for a low-power security response, and the wireless communication standard used for transmitting data through a second wireless channel at a second power level higher than the first power level, wherein the first power level corresponds to a geographical distance within which the low-power security response can be received; and
a transmitter to transmit according to the wireless communication standard, in response to said security query, the low-power security response at the first power level through said first channel if the apparatus belongs to the wireless communication system.
