Cell phone signal booster amplifiers

There are a lot of cell phone signal booster options out there and sometimes it's difficult to determine what is the best of the best. In this guide, we'll cover the best signal booster option for every type of situation that you'll encounter.

What is a Cell Phone Signal Booster?

Many people have been burned by "signal boosting stickers" and "signal boosting phone apps" that promise to improve your cell signal, but in reality never do.

Cell phone signal boosters are much different than the free solutions that have disappointed people in the past. They use powerful signal amplifiers, high gain antennas, and low signal loss cable to amplify the existing outside signal and broadcast it inside a building or vehicle.

All cell phone signal boosters on the market today have also been certified and approved by both the FCC and the major carriers, including Verizon, AT&T, T-Mobile and Sprint, as well as the other major carriers in North America.

In fact, there are millions of cell phone signal boosters currently operating in the United States as we speak, even though most people have not even heard of the term.

Do Cell Phone Signal Boosters Really Work?

How to install a cell phone signal booster

Unlike the signal booster apps and stickers from the past, cell phone signal boosters (also known as cell phone repeaters or cell phone amplifiers) have been tested and proven to work by the Federal Communications Commission (FCC).

There is no magic in how a cell phone booster works. A high powered antenna outside of the building or vehicle receives the existing cell signal and passes it over a low loss cable to a signal amplifier. The signal amplifier is specially designed to amplify only the cellular frequencies that the 2G, 3G and 4G LTE networks run on, and then pass that signal to an inside antenna, which broadcasts the strong cell signal to the inside of the building or vehicle.

The signal booster also works in the other direction. If someone is making a phone call or browsing the Internet on their phone, the signal is received by the inside antenna, boosted through the signal amplifier, and then broadcast to the nearby cell towers.

There are times when a cell phone signal booster will not work though, such as when there is no existing outside cell signal, since the booster will not have anything to boost. A cell phone booster can't create cell signal, it can only make existing signal stronger.

Most of the time though, a cell phone signal booster is going to be the best solution for weak signal, poor reception and slow data speeds.

What is the Best Cell Phone Signal Booster for a Small to Medium Home?

A cell phone signal booster for a small to medium size home needs to balance power with affordability and ease of installation. You don't want a booster with 100+ feet of cable for a small home, nor do you want an overpriced & overpowered booster either.

weBoost Connect 4G cell phone signal booster | 470103

weBoost Connect 4G Signal Booster

The weBoost Connect 4G (470103) cell phone signal booster, our best selling signal booster, is an ideal solution for homes that have a medium to strong outside signal and need to cover up to 2,500 sq ft inside of the house, or for homes that have a weak outside signal, and only need to cover up to 1,000 sq ft inside of the house. The boost kit includes everything you need to install the signal booster, except for a pole that need to mount the outside antenna to on the roof.

What is the Best Cell Phone Signal Booster for a Large Home?

Large homes typically require the maximum amount of boosting power to provide coverage throughout most or all of the space. Depending on the size or shape of the home, it may be necessary to add extra inside antennas or complete systems to achieve the desired coverage.

Wilson Pro 70 Signal Booster

The best option for large homes is the Wilson Pro 70 (465134) cell phone signal booster, which is our other best selling booster. It is more powerful than the weBoost Connect 4G, and should provide about twice the coverage that the Connect 4G is able to provide. In fact, it is the strongest that the FCC allows a signal booster to be, so it's your best bet if you need the most inside coverage possible. It also includes a lightning protector, 3 year hardware warranty, and an LCD display on the amplifier for easy installation and troubleshooting.

The Wilson Pro 70 is going to be the best option if you have a 5k sq ft home and a medium to strong outside signal, or a 2,000 sq ft home and a weak outside signal.

What is the Best Cell Phone Booster for Cars?

Signal boosters for cars are different than those used for buildings in two specific ways: they have to be able to more quickly adapt to an ever changing outside signal environment as the car is driving, and their boosting power has to be limited so that the boosted signal does not interfere with phones in nearby cars.

weBoost Drive 4G-X cell phone signal booster | 470510

weBoost Drive 4G-X Signal Booster

The best cell phone signal booster for your car is the weBoost Drive 4G-X (470510) signal booster that will allow you to be as far from the nearby cell towers as possible, and still be able to make and receive phone calls, as well as have fast data speeds.

The weBoost Drive 4G-X is incredibly easy to install, with a magnet mount antenna that you stick to the roof of the vehicle, and then flexible cable that you run through the edging of the door to the amplifier, which you can locate under a seat. The amp is powered through the cigarette lighter and the inside antenna is a small rectangle that you can velcro near the area where you typically use your phone (typically on the dashboard).

Once it's setup and plugged in, the booster just works. You can use your phone like normal and will automatically have good cell signal.

If you ever drive through dead zones or in very rural areas, this is the solution for you.

What is the Best RV Cell Phone Booster?

Cell phone signal boosters for RVs have conflicting goals, in that they're used part of the time while you RV is in motion, which means that the boosting power must be restricted per FCC regulations, but RV owners want the maximum possible coverage inside while the vehicle is stopped.

The best RV cell phone booster is going to be one that maximizes the coverage area while still being able to be used while in motion, which is the Wilson Signal Booster 4G Extreme RV Kit.

It uses our most powerful type of mobile outside antenna, for maximum coverage inside, and the most powerful mobile amplifier on the market, so the booster will work as far from the cell towers as possible.

If you're looking for a solution that can be used both while moving and stopped, and provide the largest possible coverage area inside of the RV, then the WSB 4G Extreme Signal Booster is the one for you.

What is the Best Marine Cell Phone Booster?

Marine cell phone signal boosters face the same challenges as signal boosters for RVs, in that boat owners want to cover as large of an area inside the cabin of the boat as possible, but still be able to handle the constantly changing outside signal.

What is the Best Cell Phone Signal Booster for Offices?

Office spaces and other large areas that require better cell phone signal typically require a professional system design in order to provide the necessary coverage throughout the area.

A professional design involves performing an initial analysis of the building and outside signal environment, and then using enterprise level signal amplifiers, higher grade cables and components, and high gain antennas to distribute the boosted signal throughout the space for uninterrupted coverage throughout.

It's widely considered to be the Cadillac of cell phone signal amplifiers.

What is the Best Cell Phone Signal Booster for Verizon, AT&T, T-Mobile or Sprint?

When deciding on a cell phone signal booster, you obviously want to make sure you're getting the best one for your carrier. In the past, only certain signal boosters would work with AT&T, while others would only work for Verizon, so you had to be sure you picked the right one, otherwise it wouldn't help you.

Today, the new signal boosters are all designed to work on all of the carriers, both in the United States and Canada, simultaneously, so any five-band booster that you purchase will boost the 2G, 3G and 4G LTE networks from Verizon, AT&T, T-Mobile, Sprint, Bell, Telus, Rogers, and more.

Our recommendation would be to figure out if you need to boost signal in your home, office, or vehicle, and then go with one of the suggestions covered above.


We use our cell phones in a lot of different places, and many of those places may not have the best cell service. With a cell phone signal booster, you can take signal from one area, make it stronger, and then broadcast it to the area where it's needed, in either a home, business or vehicle.
