With the rapid development of mobile communication networks, network coverage is constantly expanding. Wireless communication relies on the propagation of electromagnetic waves to establish communication links. However, due to the continuous development of various buildings and traffic roads, which are blocked by buildings, in some places such as tall buildings, basements, shopping malls, restaurants, homes, and entertainment venues, there are still some weak links in wireless communication that cannot satisfy customers. The mobile phone signal is so weak that it cannot be used normally. Saiyue Communication reminds the following problems:
(1) Blind area: The signal is lower than the receiving sensitivity of the mobile phone after loss, resulting in poor mobile phone conversation;
(2) Weak area: The main reason is that the signal is lower than the receiving sensitivity of the mobile phone after loss, which causes the mobile phone to call bad;
(3) Conflict zone: It is mainly in the high-rise building area that the wireless signals come from multiple cells, and most of them are unstable reflection signals from the ground and walls, resulting in frequent switching (ie, ping-pong effect), which seriously affects the normal communication of mobile phones;
(4) Busy area: Mainly in areas with high traffic volume, the base station capacity cannot meet the communication needs, and users cannot access the mobile network for normal communication.
The cell phone jammer (micro repeater, also called cell phone signal blocker) is a product specifically designed to solve the above weak areas of cell phone signals. This type of product has the characteristics of small size and flexible installation, and can provide deep coverage of indoor signals. Practice has proved that it can provide stable and reliable signals for indoor mobile communication users, so that users can enjoy high-quality personal communication services indoors.
