When coverage extension becomes difficult due to hills and mountains preventing line-of-sight with the BTS location, using a RF or fiber optical repeater to enhance signal coverage provides an ideal solution. Deployment of repeaters can minimize the rollout time and site acquisition is much easier approved.
Above diagram provides a typical installation layout of an outdoor project. The repeater is connected via coaxial cables to donor and service antennas. Ideally to maximize the output power of the repeater, donor and service antennas should be installed on opposite sides of the mountain to take advantage of mountain as an isolation barrier.
