When considering new uses, there is a very strong case to be made that BLE is the appropriate technology to use in order to achieve success. The reason being that the Bluetooth Special Interest Group (SIG) is intentionally building its technology to allow for effective, yet inexpensive, tracking of nearly any item.
Bluetooth provides a robust level of support for sensors of all types, allows for bi-directional communications – which allows over-the-air sensor configuration and firmware updates – and offers an excellent security model. BLE also allows for long range communication. The fact is the infrastructure is not only cheaper, but because of the range, fewer devices are needed than most would expect.
