Detailed Frequency shifting repeater (Tetra wireless repeater) Description:
Frequency shifting repeater (Tetra wireless repeater/mobile signal amplifier/800MHz/450MHz/150MHz)
1. Monitor software can be upgraded locally or remotely;
2. conquer problem of interfere from equal-frequency;
3. omnidirectional antenna，enlarge the coverage range;
4. extend the base station signal;
5. large Dynamic range，low power consumption，small figure noise;
6. voltage and over current over output protection, superheat protection and backup batteries function
7. high isolation between uplink and downlink，high stability and reliability.
Main function:
1. Auto Shut-Down;
2. over output protection;
3. ALC;
4. Software setting on gain, power and PA function;
5. power output display;
6. excess temperature, over power output, SW and door banning alarm.
Main application:
1. enlarge service range, eliminate coverage of blind area, such as alp，building，wood;
2. increase field intensity and enlarge the coverage of suburb site.
3. span along the highway, increase coverage efficiency.
4. Solve indoor coverage, such as in big building signal attenuation blind area, underground marketplace, underground, tunnel and so on attenuation signal blind areas.
5. leisure base station signal induce to busy base station coverage area, optimize the signal amplification
