CDMA and GSM signal solution covering fixed locations:
GSM and CDMA signal enhancer (mini-repeater) dedicated to small regional indoor antenna distribution system (also known as fixed-point coverage), base station signals through the wireless access directly into the indoor coverage area, and then through the small antenna will be Base stations to send out signals at the same time to receive mobile phone signals, through the distribution system up to the base station can effectively eliminate the blind spot of indoor coverage, interference suppression, for indoor users of mobile communications to provide a stable, reliable signal, so that users can enjoy high-Indoor The quality of personal communications services. Signal enhancer used in the main room at the small-area coverage, indoor coverage of mobile communications blackout, the effect of the coverage to reach the edge of field strength than-75dBm.
1, CDMA and GSM signal enhancer (mini-repeater) the scope of application:
A, the region's small signal blind spots or weak signal areas, such as underground or semi-business premises on the ground floor, small basement, underground parking and so on;
B, small signal complaints regional hot spots, such as conference rooms, a small supermarket, small shopping centers, officetel small and medium-sized public areas, and so on;
C, traffic and social impact of large areas such as bars, cafes, dance halls, cafes, health club, leisure entertainment and so on;
D, elevators, in particular, the lift wells do not respect the elevator cable laid;
E, home, office, luxury yachts, private car, public security and road safety management systems and so on.
2, CDMA and GSM signal enhancer (mini-repeater) features
A, high-gain linear power amplifier;
B, ultra-low-noise amplifier receiver;
C, there is no interference on the base station, without opening the original system and adjust the parameters of the base station;
D, stable and reliable design of electromagnetic compatibility;
E, base stations would not cause an increase in background noise, nor will it lead to a decline in the quality of communication base stations;
F, with the full-duplex communications;
G, reasonable and effective cooling, beautiful structure, the appropriate size.


Note: Donor antenna usually available Yagi antenna, can also be used parabolic antenna, the antenna plate and the ceiling antenna (access to the direction of the donor base station can not directly visible or unknown direction, but the effect of communication may be less); re-issued Indoor antenna in the general use of ceiling antenna, depending on the scope of the coverage area can also use the plate-shaped vertical whip antennas and antenna, depending on regional coverage and to determine the shape
