Definition

Location-aware technologies are devices that can report their precise geographic location at high temporal resolutions.

Main Text

Location-aware technologies (LATs) are devices that can report their geographic location in near-real time using methods such as radiolocation that exploit wireless communication systems, the global positioning system (GPS) that utilize time differences of signals from satellites in Earth orbit and dead-reckoning that use distances and directions along a route from a known location to determine the current location.

An emerging LAT is radiofrequency identification(RFID) tags. Mobile RFID tags transmit data to fixed readers using either passive (powerless) or active (powered) methods. Active tags are heavier and more expensive, but have a longer range and cheaper readers than can track multiple tags simultaneously. Unlike GPS, RFID tags must...
