As beacons transmit using a short range radio signal, position your beacons in locations where you minimize the levels of interference:
- Avoid placing them near other electronic equipment that uses the same 2.4GHz band (e.g. wireless WiFi routers, microwave ovens, wireless speakers, video transmitters/receivers, etc).
- Materials that create the highest interference are metal and water. Metal can amplify and shift the signal in different directions depending on the surface and orientation of the beacon. And as humans are mostly made up of water, position beacons ideally high enough to avoid their interference and to increase line of sight with your consumers mobile devices. Plaster, concrete, and bulletproof glass also has high interference potential.
Typically, multiple beacon deployments at a venue will share the same UUID, and use the major and minor pairs to segment and distinguish subspaces within the venue. For example, the Major values of all the beacons in a specific store can be set to the same value and the Minor value can be set individually and used to identify a specific beacon within the store.
NOTE: If you plan to use a large number of beacons, there is a unique technical constraint to consider for your app running on Apple iOS devices. Every region, be it a beacon region or a geofence is identified using a 32 character long value called unique Identifier (UUID). Apple only allows 20 such regions with unique UUID’s to be monitored at a given time - that region can be a beacon region or a geofence. Therefore to accommodate this Plexure recommends that you organise your beacons in the beacon regions carefully to keep the number of regions to a minimum.
