Choosing the right RFID and tracking technology is solution-oriented and not technology-driven

Directional antennas or array antennas offer the possibility of locating zone tagged objects. Once located, the associated passive transponder in the reception area (zone) of the antennas or array, the known position may be associated with the vehicle, the goods carrier or a person. In the truck tracking using ground transponder the principle works exactly the opposite: As soon as the truck passes over a ground transponder with certain item ID with its underbody antenna, its position is known (chessboard principle).

The BLE or WLAN positioning is based on the field strength measurement (RSSI) between the active mobile transponders (may be Device in Mobile) and stationary, distributed in buildings, halls or shopping malls WLAN access points or BLE beacon. The location accuracy of about 5m is dependent primarily on the density of the arrangement of APs and beacons. One speaks therefore in these location technologies also more of a zone detection, as from an exact positioning.
