One of the major problems with beacons is fragmentation and inability to scale apps across a real-world network. So my startup developed a beacon infrastructure API/SDK for app developers to hook into existing beacons that are already deployed. We aggregate beacon networks around the world and list them on a marketplace online so devs can use them for their contextual/hyperlocal use cases as scale.
A beacon can never be considered "occupied" like a rented apartment or a car. Instead, the number of rentals and subsequent income per beacon at any given time is unlimited.
