Tracking tags is usually associated with Asset Location Technology
and typically involves Radio-frequency identification
or Bluetooth Low Energy
Two different types of radio systems used, among other things, for asset location services.
- 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.
iBeacons are a type of active RFID
that use BLE
