How do Mobile Phone Signal Boosters Work?

If you’re considering a mobile phone signal booster, or are only just learning about them, no doubt you’re wondering how they work. It’s a fair question to ask given how many fake devices are launched that claim to boost phone signal.

The good news is that there are many legitimate signal boosters on the market that are verified by cellular carriers and government institutions like the FCC. They are considered to be completely safe and a great solution for improving mobile signal in the home, office, or car.

About Mobile Phone Signal Boosters

These boosters are systems made from an outside antenna – known as the donor antenna – and an internal antenna, a mobile phone signal amplifier, and a cable that connects everything together. The exterior antenna receives cellular signals from nearby phone towers and passes it through the cable to the signal amplifier. The signal amplifier will then boost the strength of the signal and pass it through another cable to the internal antenna, which then broadcasts it out to the area around the amplifier.

Signal boosters also work in reverse. When a nearby phone makes a call or accesses the internet, the signal passes through the booster, is amplified, and then broadcast to the nearby mobile phone towers.

These mobile phone signal boosters are designed to tackle the three main causes of bad phone signal in the following ways;

  • Being Too Far From the Mobile Phone Tower

Signal boosters amplify a weak outside signal to and from mobile phone towers to compensate for any distance.

  • Obstacles Blocking the Signal

An omni-outside antenna is able to receive and broadcast a powerful phone signal in every direction to boost the chances that a signal will get past any obstacles that might be blocking it.

  • Construction Materials

Signal boosters use high quality cables to route signals around construction materials that could be blocking the signal. They distribute signal to the areas where a better reception is required.

As long as there is some kind of phone signal available outside, your phone signal booster should be able to solve any signal problems you have and improve the service in your home, office, or vehicle.

Types of Signal Boosters

There are two main types of mobile phone signal boosters;

  • Vehicle signal boosters that are designed for on-the-go use
  • Building signal boosters are designed to be used in a single stationary location and as such as are more powerful than vehicle signal boosters

Let’s take a closer look at each one;

Vehicle Signal Boosters

Vehicle signal boosters are designed for use in cars, trucks, RVs, and boats. They must therefore be able to adapt to a constantly changing signal environment.

They generally have a smaller outside antenna than indoor boosters. The antenna is made from magnetic materials for cars and trucks, and are more permanent for boats and RVs. This antenna is connected to the amplifier with a cable, with another cable running through to a small internal antenna, which sends out the boosted signal to nearby devices.

These boosters are built with automatic gain control – the ability to adjust the amplifier’s boosting power – to adjust to the constantly changing outside signal strength. It helps to maximise the potential coverage of the booster.

Mult-carrier vehicle boosters are limited by the FCC to a maximum 50 decibel boosting power. This means that you can expect to get a smaller coverage area than you would with a booster designed for a building. Each and every carrier is boosted simultaneously though, so there’s no need to worry about different carriers getting more or less coverage.

Single-carrier vehicle signal boosters are built with a higher limit, reaching 65 decibels of boosting power. They give you a wider coverage area inside, but they only work with a specific carrier. If you know you only want to boost one carrier, this would be the better choice.

There’s a whole class of vehicle signal boosters for boosting the signal for individual mobile devices. These are going to be less powerful and come with a lower price attached to compensate. They are great for situations where you only want to boost your own phone and you deal with the occasional dead zone. They won’t be much good for rural areas though, and they are practically useless if you have to boost several devices at once.

Vehicle signal boosters can make a big difference in staying connected when travelling and going through areas with poor mobile phone signal. If you spend a lot of time in a car, truck, RV, or boat then consider getting a signal booster if you require a constant connection.

Building Signal Boosters

Building signal boosters for the home and office are designed to be installed in one location and provide coverage to the area of the building they are placed.

They work by using a powerful antenna installed outside of the building on the roof to capture an existing phone signal. This signal is then passed through a low loss cable to the amplifier inside of the building. The amplifier boosts the mobile signal and passes it through a cable to one – or several – internal antennas. The antenna will broadcast the enhanced signal to the area that needs the extra coverage like a miniature mobile phone signal tower.

These boosters also work in reverse. That is to say that they take signals from phones, amplify it, and send it out to nearby phone towers through the outer antenna.

There are different levels of building boosters available, from entry level boosters that only cover a few feet of space, to enterprise-class systems designed to provide a huge area with boosted phone signal. The higher the quality of the booster, the more powerful the amplifier and the better the quality of the components such as cables and antennas.

The boosting power of these devices varies from between 55 decibels for entry level units up to the maximum 72 decibels for high-end boosters. If the amplifier is designed for boosting signal from a single carrier, then they have a higher maximum boosting power of 100 decibels.

If you feel that one kit isn’t enough to cover the space you need, then you can invest in several amplifiers and connect them together. This lets you cover up to 50,000 square feet, if not more, with a boosted mobile phone signal.

Conclusion

Now that you know how signal boosters work you can buy one with confidence. Whether you need a better signal in your home, office, or vehicle, mobile phone signal boosters are the answer.
