Project Address 

Hongshijia, Nanzhuang Town, Chancheng District, Foshan City, Guangdong Province

 

Spot Details

The distance between the two electric houses is 50 meters,and the area of each electric room is about 30 square meters.The signal source has to go to the first floor through a wire walkway at the entrance of the electric house,and then take the signal through the lobby on the first floor.The one difficulty is the electric room line is no gap to connect lines,and there is a signal at the outdoor antenna.The installation requirements for outdoor antenna receiving signals are very high because it is in the middle of the community,surrounded by 16-story high-rise buildings.

The three network 2G signal, the signal of the electric room is covered, can make a stable call

 

Detailed process of solving problems
