Is a Mobile Signal Booster helpful?

Answer: Yes useful, but it need to meet some conditions.

Mobile Signal Booster useful conditions:

1, Place the position of the outdoor antenna must have a perfectly normal phone signal. Cell phone signal booster is relaying equipment, is the outdoor good signal through cable access, and then amplified and then forwarded to the indoor signal coverage is achieved. If placed outside antenna position signal is not ideal, forwarded to the indoor signal is not ideal.

2, The frequency to choose right. General Mobile Unicom is the same kind of frequency GSM900, telecom 2G and 3G frequency is CDMA800, China Unicom's WCDMA 3G signal is frequency, usually no 3G mobile amplifier, and now basically abandoned 3G mobile main push 4G.

3, The power to be able to meet environmental. Mobile phone signal booster power from 5mW to 200mW or so, the home environment is generally a good solution. If the power is used to host small or large with several floors of the area, there will be no effect. Too small to host, multi-cable antenna connection, the signal on the wire in exhaustion.

4, The installation method to be right. Installing the wrong way, it may cause the host to operate normally, but let the signal even worse. Installation Notes: a, install an outdoor antenna, outdoor antenna location must be able to receive a good signal, best call quality indoor and outdoor antenna can only reach the same position. b, internal antenna retransmitted signal received by the antenna can not let the outside, inside the antenna and the host should be more than one meter distance. c, the installation process, the wire material as possible, the loss of a large multi-wire. d, the distance between internal and external antennas, multi-wall separated by at least more than 5 meters apart, intermediate stop at least 10 meters less. e, the city installed outdoors as much as possible not to use Yagi antenna, the city has a strong outdoor signals, use flat or ceiling replaced because good directivity index flat ceiling is not particularly strong, Yagi also eyesores. As long as the host 100% lights on OK. Countryside or the base station are far away from the installation site, select the Yagi antenna. f, close to the amplifier from the base station, the base station antenna, the antenna can not be on the radio, outdoor best to use small antennas mounted on the ceiling or to see the location of the base station.

5, There may be installed after the call is not a normal situation, these situations are very small. Between buildings reflected signal, surrounded by too many base stations, indoor installation with frequency wireless devices may interfere with each other after.
