163:'Passive' RFID tags broadcast their location but have limited transmission range (typically a few meters). Longer-range "smart tags" use 'active' RFID -where a radio transmitter is powered by a battery and can transmit up to 2000 meters (6,600 feet) in optimum conditions. RFID-based Asset Tracking requires an infrastructure to be put in place before the whereabouts of tags may be ascertained. An asset tracking system can record the location and usage of the assets and generate various reports. Unlike traditional barcode labels, RFID tags can be read faster and have higher durability. RFID is integrated in smart warehousing to track inventory and other assets. Realtime information of the tagged objects are obtained including the location, activity and other characteristics.

in that they rely on an internal battery for power rather than being hard-wired to a vehicle's battery. The frequency with which the position of the device must be known or available dictates the quality, size or type of GPS asset tracker required. It is common for asset tracking devices to fail due

is used to calculate a distance to the signaling transmitter from the signal strength. The principles for position determination are trilateration, triangulation and fingerprinting. LoRa can be used for both indoor and outdoor tracking as LoRa signals can travel longer distances (kilometers).

technology simplifies tracking of assets by tapping the assets and getting the details. This is an advantage for tracking critical assets where user needs to see the condition of the asset to be tracked.
