BLUETOOTH LOW ENERGY (BLE)
BLE is one of many ‘Active’ RFID technologies, meaning that it has a battery and can repeatedly broadcast its identity and perhaps additional ‘payload’ information. This can be picked up by any receiving device within 10 or 20 metres, even a few hundred metres with more specialist devices...
What makes BLE stand out amongst other ‘Internet of Things’ technologies is the global adoption of its standards, and the fact it is built in to almost all smart phones as standard. They can therefore be used as both a ‘beacon’ and a ‘receiver’. The cost of a BLE based reader infrastructure can therefore be relatively low, but since BLE tags contain a battery they have a finite lifetime before they must be re-charged or replaced. Battery management must therefore be built into any business case considering this technology.
Codegate’s Lime Asset Inventory software can be used to inventory assets tagged with BLE beacons.
BLE beacons are becoming smarter, and are beginning to incorporate sensors – movement and temperature for example. Codegate is a Quuppa partner for development of solutions around their real time location technology, accurate to sub-1 metre.
