How Does A Cell Phone Signal Booster Work?

Cell Phone Repeater Reception Boosters:

Analog Signal Repeaters

The majority of different amplifiers designed nowadays are analogue. These repeaters are intended to provide amplification to all cell phone carrier frequencies. Like broadband amplifiers, they are typically sold in a package with an extension cable. With these, you will be required to install them. You will find some of them being marketed as bi-directional repeaters. This is a booster that many localities will have regulations for. For these, they will need to cater to emergency services. However, they do boost the signal for traditional cellular phone signals and two-way radios.

Smart Boosters

This is a newer technology. This is a new form of the signal booster and it leverages the use of digital baseband processors. These processors can clean up the signal before it rebroadcasts it. This means that the gains are not only higher, but better in quality. It can deliver as much as 100 dB gains. Whereas, if you opt for an analog counterpart, it will cap out at around 70 dB gains. While they can be somewhat expensive, they come with a lot of good features and they are incredibly easy to install. They don’t require any outdoor antennas and they come with an internal antenna inside of the kit. As a side point, it may be worth you taking a look at mobile signal solutions.

Why Is Your Signal Weak?

Knowing why your signal is weak is one of the best ways to improve your reception. There was one time when a test was carried out in an area surrounded by 100 feet of woods in New York and found that a signal booster was capable of overcoming the obstacles blocking it. This made for reliable and quality cell phone service for anyone in the home. Both the data and the voice reception were enhanced from it.

The Distance Between You and The Tower

The main thing you need to be concerned with when you are suffering from reception issues would be the distance between you and the tower. You need to look to see how far away the nearest tower is located. You’ll find that the closer you are, the better your signal will be. If you are located extremely far away from the tower, it’s very likely going to be weakened because of it.

You Have Obstacles Blocking It

Cellular signals are typically radio waves and they can get blocked by many things. If the radio signal has to travel a long way to get to your device, it’s likely going to be weaker. Effective transmission of waves will require little to no obstacles. It needs a clear line of sight between your device and the towers. Various external factors can block the signal including billboards, mountains, terrain and more. You will even find that weather conditions can block it too.

Inside Interference

Not only do you have to worry about external factors that can block your signal, but also internal factors. There are plenty of things that can block the signal internally. These things can include but aren’t limited to brick, concrete, and more. You want to ensure that your home isn’t blocking the reception because of its materials or that you have something else causing poor signal. If you notice that you have a crystal clear signal outdoors, you are likely dealing with something internally.


Every amplifier or booster needs to be certified whether sold in the United States or Canada. The Federal Government of each country will need to certify the signal booster for use in the country. This certification is meant to give consumers confidence that the booster does what it is intended to do. It’s meant to showcase the efficacy of the product. The Federal Communication Commission is responsible for certifying them in the USA and Industry Canada is responsible in Canada.
