ABSTRACT:
Disclosed is a proximity aware personal alert system including a first mobile transceiver unit and a second mobile transceiver unit in communication with the first mobile transceiver unit via an RF link where the second mobile transceiver provides an alarm indication when the first mobile transceiver has moved a predetermined distance from the second mobile transceiver unit. When the RF link is configured as a Bluetooth link, the first and second mobile transceiver units form a monitoring piconet where the second mobile transceiver unit provides the alarm indication when the first mobile transceiver unit moves beyond a distance of approximately ten meters from the second mobile transceiver unit. The first transceiver unit is worn by a monitored person such as a child and the second transceiver unit is worn by a monitoring person such as a parent of the child.
