Abstract: A geofencing system (310) that does not rely on a GNSS or other like system. The geofencing system comprises a group of two or more fence-pole devices, FPDs, that define a geofenced area (399). Each FPD in the group is capable of making its own determination as to whether or not a certain communication device (377, 378) appears to be within the geofenced area. In one embodiment, if all of the FPDs have determined that the communication device appears to be within the geofenced area, then it is decided that the communication device is within the geofenced area. In another embodiment, if the group of FPDs consists of N FPDs and at least N?1 of the FPDs have determined that the communication device appears to be within the geofenced area, then it is decided that the communication device is within the geofenced area.

Abstract: The light communication solution presented herein uses waveguides with multiple entrances to efficiently collect light used for light communications and propagate that collected light to a sensor. To that end each waveguide entrance, or at least all but the initial waveguide entrance, is configured to not only collect and input the light into the TIR waveguide, but also to maintain TIR of light already propagating within the TIR waveguide.

Further, because each waveguide may channel light from multiple collection points to a single sensor, the solution presented herein reduces the number of sensors needed for the light communications. The solution presented herein facilitates the implementation of light communications for a wide variety of devices (e.g., cellular telephones, tablets, smartphones, smart watches, smart glasses, etc.) and/or in a wide variety of scenarios.
