Abstract
A system includes a first transceiver and a controller circuit. The first transceiver is configured to transmit first radio frequency (RF) signals. The first transceiver is further configured to output the first RF signals at a first transmission level corresponding to a first transmission range. The controller circuit is communicatively coupled with the first transceiver. The controller circuit is configured to attenuate the first RF signals to transfer the first RF signals at a second transmission level lower than the first transmission level. The second transmission level corresponds to a shorter transmission range than the first transmission range. The controller circuit detects a presence of at least one second transceiver within the shorter transmission range using the first RF signals transmitted at the second transmission level.
