How many decibels does the mobile signal attenuate through the metal?

Adjustment and optimization of weak field strength value region

Mainly the adjustment and optimization of indoor area, because the attenuation value of radio waves entering the room through various walls is about 15 dB-20dB, so it is necessary to strengthen the field strength value of indoor area.

For high-rise buildings and hotels that have been built and put into use (generally above level 3), if indoor distribution system can be used technically, indoor coverage points should be given priority; If the indoor distribution system cannot be used technically (some property management departments do not agree to the construction), micro-cellular sites should be considered; For buildings under construction or proposed (especially high-grade buildings), we should actively contact the owners and strive to lay out the indoor distribution system in the construction stage.

Indoor coverage stations can independently add frequency points to build stations according to the actual situation, or they can use the original frequency points of outdoor stations to build stations (outdoor and indoor carrier frequencies can be enjoyed through antenna splitters * * *); Directional wireless distributed indoor coverage can be constructed, and omnidirectional antenna distributed indoor coverage can also be constructed.

The above is an effective method to improve the weak field strength in prosperous areas. On the one hand, it can solve the interference problem of high-rise buildings, on the other hand, it can improve the connection rate and absorb the traffic.

At present, the new provincial government building, provincial post and telecommunications administration, provincial mobile company building, Fuzhou telecom hub building, Dali Jiacheng building, Gemini building and other base stations in Fuzhou have achieved indoor coverage, and micro-cellular stations have been built in post and telecommunications apartments and other base stations.
