The RPT-9000 can easily address underground parking, tunnels, and mines with bad reception or dead spots.

In this example, the cell tower is sitting above ground and unable to penetrate the underlying structure which may be a parking lot, tunnel, or mine.

The RPT-9000 above ground donor antenna will receive a signal from the cell tower, pass underground through a cable, regenerate to full power and transmit with a fill antenna to the underground users.
