Abstract: The Remote Radio Head (RRH ) over Fiber system is a new distributed network coverage mode. It processes the baseband parts concentratively by separating the baseband and Radio Frequency (RF ). It moves the RF modules using fibers from the Base Stations (BSs ) to the remote RF units. These RF modules are placed on the stations to be covered. This solution saves many equipment rooms required by conventional solutions. Meanwhile, it supports RRH over a large number of fibers through high-capacity macro BSs to realize the conversion between capacity and coverage. In addition, the RRH system also supports the coverage in other situations, such as high-speed railways and ultra-long distance. It is one of the most widely used technologies in the 3G network.
