  4. 4. • You might have noticed, that RSSI readings from Beacons are less accurate and fluctuate more on Android than on iOS. That’s because the Bluetooth stack on Android is still in a fairly early stage of development compared to its iOS counterpart. • RSSI stands for received signal strength indicator. It’s a value used for estimating proximity. You need to remember though, that Beacon’s signal is simply a radio wave and therefore is susceptible to factors like diffraction, multipath propagation, interference and, what’s probably most important, absorption - especially by human bodies, mostly consisting of water particles. So, proximity measurements based on radio waves, should take all those factors into account. Apple has implemented basic noise reduction algorithms into its Core Location framework, on top of which iBeacon standard is built. This allows for much more accurate RSSI readings.
  5. 5. • Android, on the other hand, has a much simpler Bluetooth stack at the moment, with no noise cancelling methods. We’re working hard to keep improving responsivity of our Beacons, but be wary that currently RSSI readings will be less reliable on Android than on iOS.
