If you live in a location that receives poor cellular signals and face troubles with the clarity of voice calls as well as internet browsing speeds, the best possible solution is a cell phone booster. It is a simple device that helps you handle the issues in cellular network by boosting the signals available at your location. A cell phone booster functions as a repeater that takes in weak signals, amplifies them and rebroadcasts them to desired locations.

In an attempt to understand the working of the device better, we make a brief discussion about the components of a cellular signal booster. The working of a cell phone booster is relatively simple and the system has 3 main components which are:

External Antenna

The boosting function begins at the external antenna end of the cell phone booster. The external antenna is usually mounted high on rooftops of buildings and vehicles to pull in the available cellular signals effectively, whatever be their strengths. The antenna has connections to the next component, the amplifier via cables and it sends in the captured signals to the amplifying unit.

External antenna is of two types, which are:

  • Omni-directional antenna– This type of antenna pulls in signals from a 360 degree angle, and being an all round performer, the antenna type suits locations that receive decent signals or when people want to boost multiple carriers.
  • Unidirectional antenna– This type of antenna takes in signals from a 45-degree angle and is used in locations that receive signals from a single carrier signal tower.

Amplifier

The amplifier is the major component of the cell booster, and the unit performs the crucial task of boosting cellular signals. The coverage range required for an amplifier varies according to the strength of the external signal and most of the amplifiers have a coverage range between 500 to 7000 sq feet.

All signal strengths in cell phone boosters are measured in decibels with the output of the amplifiers too measured in decibels. Amplifier power is measured in decibel-milliwatts. The decibel values of cellular signals range from -50dB to -120 dB, with signals getting weaker while strengths get closer to -120dB. The minimum required decibel gain of an amplifier is +60dB.

Inside Antenna

The inside antenna receives the boosted cellular signals from the amplifier and rebroadcasts it to the required points. Two types of inside antenna are:

  • Panel antenna- It is usually mounted on walls and rebroadcasts signals to areas closest to the wall.
  • Dome antenna-It is usually mounted on ceilings and distributes signals equally across the coverage area.

In instances when signal strength at a location is weak for all carriers, which is especially common in remote places, switching carriers cannot help improve the signal. In situations like that, installing a cell phone booster is the most feasible solution.
