Project description：2 km power working in the tunnel and shaft mobile phone signal repeater solution. In tianjin, China electric power tunnel coverage system, length of about 2 km, tunnel with 3 shaft,
Need to tunnel and shaft section tunnel three netcom signal booster cover, installed after the completion of the tunnel can achieve normal call + Internet access inside the hole.
Cell phone signal solution design
1, the first is the tunnel, adopting the proximal yituo two optical fiber repeater station + distal fiber optic repeater station to cover of tunnel, each remote connect two planar antenna, covering distance is about 900 meters, so the two distal covering distance of 1800 meters. Because the tail part of bending Angle, at the end add a 2 w power wireless repeater stations, used to cover the tail curved tunnel segment.
2, areas covered: well within the area is not large, can be used 3 w power repeater station 2 for each shaft indoor signal enhancing channel mobile phone signal coverage.
