In certain indoor environments where GPS signals are unavailable or low quality, we will deploy Bluetooth transmitters (known as beacons) to assist in positioning devices.
These beacons are standard battery powered iBeacons (a protocol developed Apple). They are Bluetooth Low Energy, advertising on all 3 advertising channels every 900ms. They transmit at the maximum permissible BLE signal strength +10dBm.
The quantity and positioning of beacons required will vary, dependent on environmental factors and required location accuracy. We will determine this in the planning phase ahead of any deployment.
