I’m seeking a BLE receiver that has a limited azimuth so it could essentially serve as a limited directional receiver. For example, a receiver with an azimuth of 90+/- degrees could discriminate between beacons on the left vs beacons on the right of an outdoor area.
Indoors the reflections off surfaces would likely complicate issues. My purpose is not to limit the omnidirectional character of a beacon transmission, only that of the receiver.
Perhaps this an idea? Is this even possible?
