Proximity sensing[edit]
"Electronic leash" applications are well suited to the long battery life possible for 'always-on' devices.[18] Manufacturers of iBeacon devices implement the appropriate specifications for their device to make use of proximity sensing capabilities supported by Apple Inc. compatible iDevices.[19]
Relevant application profiles include:
FMP — the "find me" profile — allows one device to issue an alert on a second misplaced device.[20]
PXP — the proximity profile — allows a proximity monitor to detect whether a proximity reporter is within a close range. Physical proximity can be estimated using the radio receiver's RSSI value, although this does not have absolute calibration of distances. Typically, an alarm may be sounded when the distance between the devices exceeds a set threshold.
