Tracking tags

Overview#

Tracking tags is usually associated with Asset Location Technology and typically involves Radio-frequency identification or Bluetooth Low Energy (BLE)

Bluetooth Low Energy (BLE) vs. RFID #

Two different types of radio systems used, among other things, for asset location services.

Active RFID vs. passive RFID#

  • Active RFID systems (otherwise known as active RTLS) are battery-powered sensors that connect to various access points throughout an area (like a building) and transfer data to the cloud.
  • Passive RFID, on the other hand, is what you most often think of as RFID. This technology uses a high-power, low-frequency actuator to radiate toward a tag. The tag absorbs the energy and radiates back at a higher frequency and lower power.

RFID vs. iBeacon#

iBeacons are a type of active RFID that use BLE.
