Abstract
A system for detecting proximity between a first transceiver and a second transceiver. Each of the first and the second transceivers includes at least one primary and secondary radio module. The primary radio module of the first transceiver is able to communicate with the primary radio module of the second transceiver, and the secondary radio module of the first transceiver is able to communicate with the secondary radio module of the second transceiver. The first and the second transceivers are configured to estimate a primary communication distance between the primary radio module of the first transceiver and the primary radio module of the second transceiver, and estimate a secondary communication distance between the secondary radio module of the first transceiver and the secondary radio module of the second transceiver.
