Abstract
A transceiver is configured to: pair with a mobile device; and transmit a predetermined signal from an antenna to the mobile device. A zone module is configured to: receive a signal from the mobile device in response to the predetermined signal; and based on the signal, select a zone within which the mobile device is present from a group consisting of: a first zone that is defined by a first radius from the antenna; a second zone that excludes the first zone and that is defined by a second radius from the antenna, where the second radius is greater than the first radius; and a third zone that is radially outward of the second zone and that excludes the first and second zones.
