Therefore, the selection of the access source of the indoor coverage signal has attracted more and more attention.

Under the existing technical conditions, the current solution to indoor signal coverage is mainly to use wireless signal relay amplification equipment to introduce the signal of the outdoor donor base station into the room after amplification and forwarding, thereby enhancing the indoor signal coverage. However, the existing indoor signal introduction method generally uses a directional antenna to introduce the signal of the outdoor donor base station when selecting a signal source. Once the directional antenna is installed, it points to a fixed direction. If the antennas of the surrounding donor base stations are adjusted, the directional antenna The signal of the original donor base station may not be received; or, when a new base station appears, and the signal of the new base station is better than the signal of the original donor base station, the directional antenna can only receive the signal of the original donor base station, these problems will be greatly The quality of the access signal is affected, which in turn affects the indoor coverage.

Therefore, how to propose a method for improving the quality of the access signal is an important issue to be solved urgently in the industry at present.
