In this section we will drill down a little further in to the technology and terms associated with iBeacons.
We will update this section fairly often so it’s worth keeping an eye out.
Here are some common phrases that you will come across when working with iBeacons:
RSSI (Received Signal Strength Indicator)
This is a measurement of the power present in a particular radio signal. The strength is predominantly an indication of the TXPower level (Trasmission Power). If the TXPower is set to the maximum level then the potential range of the iBeacon will be from a few centimetres to 100 meters.
iBeacons transmit in all directions. The iBeacon is at the centre of a sphere with the signal direction heading out at all angles.
Notwithstanding the fact that interference will play a bit part in the range of an iBeacon (walls, people etc), the range can be set from a few centimetres to nearly 100 metres.
Of course, the battery will become depleted more quickly with large ranges.
Battery Strength and Signal Degradation
Battery strength does not have a direct impact on the signal strength unless the battery has reached critical level in an iBeacon.
