A solution to solve all the problems
Walkie talkie Two-way Repeater Box
Multi-storey and wide-body buildings, the floor no signal dead end program
C points in the total station or lobby, D point in the building of a high angle. Passage mode signal is weak, can not listen to clear speech.
A and B two walkie-talkie as a transit signal source, for the C and D of the transit from the bridging role.
A and B are located in the middle of the building and are distributed on different floors. So that the entire building in A, B under the coverage of two signal sources.
Antenna is upgraded to high gain outdoor antenna. Antenna gain up to 6.0 dB. The radio signal is further enhanced.
Antenna and walkie-talkie are connected via feeder. The location of the antenna can be more flexible.
If necessary, between the antenna and the walkie-talkie, increase the power amplifier and other equipment, and further expand the signal strength and not the area.
