I have an engenius working in a Power plant ambiant noise level 90db to 120db. The device has a vibrate mode and works fantastic even without the external antenna kit.
The building is large and industrial as you can imagine and has worked in every area so far.

The base is located on the second floor and reaches all three levels and both ends which is about 65 meters or 190 feet.

The users love it. So we just bought the demo off the vendor saved us ordering again.
