What is a cell phone amplifier? A: The phone is designed to solve the blind signal designed for mobile products. Since the cell phone signal is transmitted by electromagnetic waves to communication links, the building of the barrier, to establish in some tall buildings in the cellar, shopping centers, restaurants, homes and other home entertainment and many other places, is mobile signal is very weak is not functioning telephone. Phone amplifier can be a good solution to these problems. Phone amplifier radiation of significance? A: Actually, the radiation cell phone signal amplifier is very small, it amplifies the signal exactly as in the outdoor signal is the same as under normal circumstances, so we should not be about what radiation is very strong on the human body concern is not well , this radiation is in the range of human health. When the phone signal is weak, the mobile transmit power when searching for repeating 1000 times more than normal, and very power. In this case, a long conversation, it is easy to cause injury. On the contrary, a good cell phone signal transmission signal is weak, thus the damage to human body. It is strongly recommended to improve the network signal to reduce the mobile transmit power, the quality of the connection. GSM900 frequency band: China Mobile :890-935-954MHz 915MHz-909MHZ China Unicom :909 954-960MHz Gain> 60 dB, what we often say is, Unicom mobile 2G card. Full coverage area? A: The complete coverage in open areas can be more than 300 square meters, the house in place of 1-200, depending on the actual installation Umgebung.Einfache: What you need to install: a repeater, an outdoor high-gain Yagi antenna, an indoor antenna, cable and an AC power adapter, and on and on repeater has three ports: 1 A DC connector for a 9V DC input. Second An N-type RF connector for connecting to an indoor antenna. Third an N-type connector for connection to a Au?enantenne.Die Installation is simple and no configuration or tuning is required. Install Yagi antenna, and outdoor and indoor antennas or connect the cables and power, and go! We would like to introduce different types of cell phone amplifiers to you on ESPOW. Buy a good phone booster kit from here to your cell. Designed for use in large office buildings, warehouses and manufacturing plants with shady signal environments, provides 65dB Cellular (890th 0-915. 0 MHz) band and coverage area of ??2000 square meters and works with all cellular carriers, which on the 900 MHz frequency . work With it, you will experience fewer dropped calls, higher data rates, and clear reception.
Recommended to improve the network signal strength, the mobile transmit power, improve the quality of the connection to reduce cell phone radiation-in-one network optimization new cell phone booster
