I work in hospitals ,, every hospital has dozens of transmitters that operate on the 800/850/900/1800/1900 cell freq’s to block calls ... doesn’t make sense to me they “jam” calls on the pretense that they may interfere with equipment and then they themselves flood the building with the very same freq’s with their jammers??? All this does is force cell phones that were left on to operate at higher output levels attempting to communicate with the tower... makes the situation worse it would seem.
But my point is the hospitals aren’t getting sued and they are using the same freq’s/spectrum.. AND they are obviously costing the cell companies revenue.
Our hospital issues cell phones for mobile workers who must stay in touch. We also use Vocera for workers who must keep in touch, which I understand uses windows mobile 6.1 smartphone technology. Very snazzy gadget the Vocera is. Think of Star Trek communicators, truly hands free communication.
