If every BT beacon has to tuned manually by taping, the deployment becomes a difficult task. I suggest we retain only A, B, and C, three levels of EM wave blockage, which represent short-range, mid-range, and long range beacons respectively. For task prompting at large areas, we use C. For tasks that have to be measured in very short range, we use A. For those in between, we use B. Too many levels will result in intensive labors and fine tuning, which are probably not a good idea.
