Abstract : The gap of radio frequency technology in cell is a reinforced technology of base station coverage ,
which is an emerging technology and can provide the scalability of system capacity and system match and so
on. This paper makes a detailed analysis of the drop of the accessed power of donor base station as a result of
the reverse interference caused by wireless repeater , greatly reduced the reverse capacity of donor base station ,
also briefly discusses the access problems for mobile users in far repeater as a result of increased users of donor
base stations in the munication repeaters client. The gap technology of RF is deeply analyzed ,the
maintenance of the technology experience in the early stage is summed up , finally it points out the prospects of
the work construction.
