Antennas
Antennas are the BLE signal receivers installed in the site's zones. Each antenna captures the BLE advertisements emitted by the beacons and sends them to the server via MQTT for location calculation — the antenna itself acts as a gateway (BLE → MQTT), with no need for an intermediary device.
Beacons
Beacons are the tracked devices on the ION Guard platform. Each beacon emits BLE signals that are captured by the antennas installed in the site's zones and sent to the server via MQTT to determine its location by zone.
