Method to Improve Wireless System Communication Coverage in a Bended Tunnel Environment

The conventional methods of improving wireless system coverage performance are to increase the transmitter power and/or antenna gain. The high transmit power could lead to more power consumption and RF exposure issues. The use of a high-gain antenna could lead to a larger antenna size and increased weight and volume. An alternative approach would be to capture the available signal power more efficiently without increasing the transmitter power and/or increasing antenna size.
