Asset tracking in industrial settings - A review of wireless technologies part 2: RFID-, GPS-, and Chirped frequency-based systems

The industry is looking forward to adopt wireless technologies for asset tracking to improve profitability and productivity. RFID, GPS-based, chirped frequency-based, received signal strength indicator (RSSI)-based, RuBee (IEEE 1902), and ultra-wide band (UWB)-based are some significant wireless technologies that are being used by the industry. The RFID system include a database application, asset tag readers, and the tags. The RFID system require a reader and and interrogator to obtain data. The RFID system can be customized to meet the specific need by using a license-free (ISM) frequencies. The GPS-based asset tracking and automotive navigation systems need a receiver on the asset to pick up signals from satellites. Chirped frequency-based asset tracking can obtain location and sensing information from a wireless field transmitter.
