Cell signal boosters increase the range of your cell phone service. If your calls are frequently dropping or you find yourself with the dreaded "No Service" notification more often than you'd like, a cell signal booster is just what you need.

What Is a Cell Signal Booster?

A cell signal booster, also called a cell repeater, is a device that increases the signal that your phone sends to a cell phone tower and the signal that the cell phone tower sends to your phone. By amplifying the signal, you'll be able to get services in places you otherwise wouldn't. These are not wifi boosters and will not increase WiFi signal (Wi Fi signal) since they operate solely on your cell service.

How Does a Cell Signal Booster Work?

A cell signal booster captures the LTE signal sent from the tower, boosts it, and then rebroadcasts it where you need it. It uses three components to amplify your available cell signal, including:

Outside Antenna

These are usually installed on the roof of your building or the window of your car. They send and receive signals from the nearest cell tower.


An amplifier increases the signal coming from the tower and the signal going to the tower. It's sometimes referred to as a bidirectional amplifier (BDA) booster or a repeater. It's connected to both the outside antenna and the inside antenna.

Inside Antenna

The inside antenna rebroadcasts the amplified LTE signal to your cell phone. It also picks up the signal from your phone so that it can be sent back to the amplifier and then rebroadcast with the outdoor antenna.

What Is Signal Booster Gain?

Signal booster gain tells you how much the signal from the outside antenna is amplified. The bigger the number, measured in decibels (dB), the more the signal is amplified. 

Another aspect of amplifier power you should be aware of is downlink output power. It is measured in decibels per milliwatt (dBm) and tells you the maximum signal that the amplifier can retransmit through the inside antenna.

To figure out which specification is more important for your situation, you need to understand these terms. If you have a weak outdoor signal, for instance, or if you're far away from a tower or there's an obstruction blocking your reception, the most important factor will be the signal gain. You want a booster that will maximize the signal you do receive from the tower.

If you have a strong signal from the tower reaching your outside antenna, then your main concern will be downlink output power. You already have a strong signal to amplify, so you want it rebroadcasted as widely as possible.

Can I Get a Better Cell Signal in a Car or Other Vehicle?

Bad cell service reception when you're in a vehicle is usually caused by one of several factors, including:

  • Distance from cell tower
  • Interference from other devices
  • Materials used in vehicle construction blocking signals

You can improve your cell reception when you're in a car, RV, or even a boat. Signal cell boosters work the same way in a vehicle that they do in a building. The components will include:

  1. an outside antenna attached to an exterior window
  2. an amplifier in your car
  3. an inside antenna in your vehicle


The outside antenna captures the signal, while the amplifier boosts it and the inside antenna retransmits the amplified signal.

Since the best cell signal booster will depend on your circumstances, we've compiled a list of the best-performing boosters by category.
