Marvelmind indoor positioning system supports today (Jan.2022) up to 250 beacons (stationary + mobile combined) and up to 250 submaps per map.
Each submap can be up to 1,000m2. Actually, it is a bit overstretch, because the recommended maximum distance from beacons is 30m. Nevertheless, 1,000m2 or up to 30m in absolute distance is an easy to remember rule.
Thus, it is possible to build very large maps. For example, if you have an empty warehouse, like a stadium under a roof, it is possible to cover up to 250×1000=250,000 m2. But it is a rather theoretical upper limit, because the real coverage is limited by the line of sight, first of all. Therefore, the maximum size of a map mostly depends on the complexity the area rather than on its sheer area in square meters.
See more examples how to build maps for different applications in the Placement Manual.
Remember the main requirement for the system:
The main required defines nearly everything in the system: the number of beacons required, update rate, complexity, etc.
First of all, check the video about maps submaps, service zones, handover zones.
Maximum size of a submap is defined by the main requirement for the system: to have tracking the mobile beacon must have a direct line of sight (hearing) to two or more stationary beacons within 30 meters for 2D or three or more for 3D.
Therefore, to be very precise, the maximum recommended area of a 2D submap is smaller than 1,000m2, because the maximum distance for 1,000m2, if the area is square-shaped is sqrt(1000) and that is more than 30m.
But the 30m limit is not a hard limit either. The system is pretty comfortably supports 33.33m maximum distance as well. Thus, an approximation of up to 1,000m2 per submap holds.
The size of a submap depends on many parameters:
