Technical Implementation: How BLE RTLS Works? 

A typical BLE RTLS deployment is built around a small number of core components.

1. • BLE Beacons and Tags: These small devices attach to assets and transmit signals at regular intervals. There are a variety of third-party Bluetooth tags in various shapes and sizes that typically offer multi-year battery life with configurable update rates. 

1. • Receivers or Gateways: Positioned strategically, these capture BLE signals from beacons and tags, relaying the data to a central system. 

1. • Data Processing: Location is calculated using received signal data and made available through APIs or asset management platforms. Most systems support standard formats such as iBeacon and Eddystone, alongside proprietary frames. The Bluetooth low energy data transfer rate is optimized for small, frequent data packets rather than high-bandwidth communication.
