Problems solved by technology

However, once the service of the base station in the new cell is busy or there is a temporary failure, resulting in no extra channel allocated to the new user, the switching of the base station will fail, which will also cause the user's call to be interrupted.
This situation can only be improved by operators adding base stations, and users themselves cannot improve

Embodiment Construction

[0019] see figure 1 , a mobile phone signal booster, comprising an outdoor antenna, a coaxial cable, a power divider, a coupler, an indoor antenna and a power supply, wherein the outdoor antenna is wired with the power divider through a coaxial cable, and the power divider, the coupler and the indoor The antennas are connected in sequence, and the power supplies are respectively connected to the power splitter and the coupler. The wire impedance of the outdoor antenna is 50 ohms. Coaxial cables are 50-7 or 50-12(1 / 2) or 50-22(3 / 4) wires. The power divider is a microstrip power divider wired in parallel. The couplers are wired in series; the N outdoor antennas need N-1 couplers.

[0020] The outdoor antenna connects the outdoor signal by cable, amplifies the downlink through the power divider and coupler, and then transfers it to the room to make up for the blind spot of the mobile phone base station; then passes the mobile phone signal through the uplink of the coupler and ...

Abstract

The invention discloses a mobile phone signal booster which comprises an outdoor antenna, a coaxial cable, a power divider, a coupler, an indoor antenna and a power supply, wherein the outdoor antenna is in wired connection with the power divider by the coaxial cable; the power divider, the coupler and the indoor antenna are sequentially connected; and the power supply is connected with the power divider and the coupler respectively. The booster can effectively improve various technical problems of poor mobile phone signal introduced in the background technology. An outdoor signal is connected into by the outdoor antenna of the booster in a wired manner, amplified by downlinks of the power divider and the coupler, then switched into a room, and used for making up a blind spot of a mobile phone base station, and a mobile phone signal is amplified by uplinks of the coupler and the power divider and then transmitted to the base station, so that communication is realized, and the booster is very convenient to use.

Description

technical field [0001] The invention relates to a mobile phone communication electronic device, in particular to a mobile phone signal booster. Background technique [0002] Mobile phone has become a kind of indispensable communication tool for people at present. When using a mobile phone, the signal is poor, and the problem of being unable to call or be called often occurs. These problems are mainly reflected in: [0003] The outdoor street has a good signal, and the indoor signal is poor. This is the most common situation, mainly caused by the surrounding buildings blocking the signal of the base station. [0004] There is a weak signal outdoors, but there is basically no signal indoors. The poor signal is due to the lack of dense base stations in rural and suburban areas, and some places are far away from the base stations, resulting in weak signals. [0005] The outdoor street has a good signal, and there is basically no signal indoors. The poor signal is because t...
