A cell phone booster is used to improve the cell reception in areas where the cell reception is weak. This device is designed to capture the existing outside cell signal, increase its strength, and then rebroadcast it to all the nearby devices. A cell phone booster can be used inside your house, your office, or even in your car.
With a signal booster at your house, you do not have to worry about call drops or slow data speed anymore. The signal booster will provide you with better cell signals that will help to make calls and use high-speed data. It also helps to improve voice clarity by decreasing noise and distortion.
Major Signal Booster Components
The external antenna, amplifier, unit, internal antenna, and the coaxial cables are the 4 major components of a cell phone booster. Let’s take a look at each one of them.
The main purpose of the external antenna of a signal booster system is to capture the cell signals coming from the nearest cell tower. It works as an anterior limb of the cell phone booster system. You need to choose the right external antenna for ensuring the better functioning of the signal booster. Based on the location of your house, you need to choose between an omnidirectional antenna and a unidirectional antenna.
The omnidirectional antenna can receive cell signals from all directions. This type of external antenna can capture cell signals from multiple cell towers at once. It is the ideal choice for houses located in an urban area and surrounded by multiple cell towers. It is also the best choice for the external antenna in an in-vehicle cell phone booster.
If you are surrounded by cell towers but still not getting a proper cell reception inside the house, that might be because of the obstacles that block the cell signals like large buildings and tall trees. In such a situation, an omnidirectional antenna would be ideal because you don’t need to adjust the direction of the antenna to find the best outside cell signal.
The unidirectional antennas are designed specifically to capture cell signals from a single direction. They can receive cell signals from long distances because they are powerful than the omnidirectional antennas. Yagi antenna and the log-periodic antenna are the two types of unidirectional antennas available in the market. These types of antennas are mainly used in houses located in remote areas.
If you are living in rural areas and not getting a proper cell reception due to the long distance from the cell tower, use a yagi antenna for the signal booster instead of an omnidirectional antenna. It is 10 times more powerful than an omnidirectional antenna and can boost any type of cell signals.
Another type of unidirectional antenna used in the cell phone booster system is the log-periodic antenna. It is about 30 times more powerful than the yagi antenna. A log-periodic antenna could easily capture cell signals from more than ten miles. This type of external antenna is ideal for those who are living in remote locations.
The amplifier unit is the most important part of a cell phone booster system and is often considered as the heart of the system. It is the duty of the amplifier unit to increase the strength of the cell signals provided by the external antenna.
The amplifier unit effectively copies the cell signal it receives by simply adding the gain factor to the received cell signal. Mathematically, the gain is the ratio of output to the input signal and since the output signal strength is always greater than input signal strength, the gain of the amplifier unit is always positive.
The internal antenna of the cell phone booster is for redistributing the cell signals amplified by the amplifier unit. The internal antenna is always installed inside the building and its position is chosen carefully to ensure better cell reception. Panel antenna, dome antenna, and whip antenna are the three main internal antennas available today.
The panel antenna is used for redistributing amplified cell signals in hallways and long narrow rooms. This type of internal antenna is also used in multi-story buildings. The panel antenna sends the boosted cell signal in a bean pattern and has a 45-degree coverage.
The dome antenna is the best choice for single-story buildings and square-shaped rooms. The dome antenna is mounted on the ceiling and could redistribute amplified cell signals equally to all parts of the room. The third type of internal antenna is the whip antenna, which is mainly used to redistribute boosted cell signals in small spaces, like a car.
The coaxial cable connects the external and internal antennas of the signal booster to the amplifier unit. Just like the other three components, the coaxial cable is also important because it functions as the nerves of the cell phone booster system.
