Hi,
Here Proximity beacons require power control coz, we will push notifications based on the proximity so there is a possibility of deploying proximity beacons at each row with in the hall and it should not overlap with other proximity beacon coverage.
We need one location beacon to cover a hall , one location beacon will cover approx 2500 SFT ( or one location beacon can handle approx 70 clients) hence we don't deploy location beacon on every row with in the hall but we need atleast 3 beacons to triangulate and estimate the location.
Hope you got some more clarity on this.
Please feel free for any further queries on this.
