A cellular phone amplifier, also known as a signal booster, signal extender, or cell phone repeater, is a device that increases the signal strength of cellular phone signals. It does this by picking up the existing signal from a cell tower, amplifying it, and then rebroadcasting it into a desired area.

Sometimes, our mobile phone has poor signal reception in our house, the reasons are as below: Distance from the nearest cell tower. The farther away you are from a cell tower, the weaker the signal will be. If you live in a rural area or in a valley, you may be further away from cell towers, which can cause poor reception. Building materials. Some building materials, such as concrete, brick, and metal, can block cell signals. If your home is made of these materials, it can make it difficult to get a good signal.

The type of cell phone signal you need: There are signal boosters for 3G, 4G, and 5G cell phone signals. Make sure to choose a booster that supports the type of signal you need.
