What is a signal? Actually, signal refers to radio waves. When there are related obstacles or there are Internet And Cell Phone Blocker places, it will not be able to spread and receive smoothly. In daily life, the more common scenarios are, for example, walking into the basement, walking into the elevator, or walking into the area with signal jammers and cell phone jammer near the examination room. Well, if that's the case, you just need to get out of the area and get your phone's signal back. "Base station coverage area" means that each base station corresponds to a coverage area determined by "transmit power and antenna height". Multiple coverage areas constitute the service area of the entire system. Therefore, if you have just stepped out of the coverage area of the signal, you may suddenly lose the signal. In real life, many times due to fast-moving calls, such as on high-speed trains, subways, etc., there may be a sudden signal interruption, and then quickly recover. This is a "handover".
Because the mobile phone will continue to maintain basic contact with the base station during the mobile call, but the coverage of the base station is limited. Therefore, due to this distance and other reasons, the current base station cannot provide normal calls. During the normal call, the mobile phone signal can be switched to the surrounding base station with relatively good call quality , called handover.
