Indoor distribution system is a successful scheme for indoor users, for mobile communication environment to improve the building; it is a distribution system using the indoor antenna signal will be uniformly distributed mobile base station in every corner of the room, so as to ensure the indoor area has a good coverage.

Indoor distribution system is mainly to solve the following issues:

1.In the low layer, underground shopping malls, underground parking lot and other large construction environment, the base station receives the signal is very weak, leading mobile phone does not work properly, forming a signal coverage area.

2. In the middle of the floor a large building, because the mobile phone can receive the signal around a number of different base stations, the base station signal overlap, producing the ping-pong effect, seriously affected the normal use of mobile phone

3. In the upper part of a large building, the wireless signal into the room is very messy, both signals near several base stations, also not far from the base station signal into the room through the reflection, refraction, reflection and diffraction, resulting in strong and weak signal reception indoors and extremely unstable, with the same frequency, the adjacent frequency interference is serious. 

Mobile phone use in this environment, in the idle state when the cell reselection is frequent, frequent switch during the call, the voice quality is greatly affected, prone to drop phenomenon

4. In addition, in some buildings, although the phone is able to call, but the user density is too large, the channel is very crowded, mobile phone online difficulties.

The principle of improving the communication environment of the building of indoor distribution system

The signal of the base station through the cable directly into the interior of each region, and then through the small base station antennas to send out the signal so as to eliminate indoor coverage blind spots, restrain the interference, to provide stable and reliable indoor signal for the building of mobile communication users, users can enjoy indoors mobile communication service high quality.
