Cell Phone Signal Boosters Buying Guide

Can You Hear Me Now?


A cell phone signal booster is also called a cellular repeater. This is a fairly new addition to cell phone technology. Before you buy a cell phone signal booster, you should account for a couple of things such as the mobile carrier supported by the booster, the area that requires coverage and the hardware that comes with this booster.

Cellular repeaters are an incredible invention. However, you should have a clear understanding of how these boosters work to avoid getting frustrated. For instance, you shouldn’t go to the Amazon forest, and expect to get your emails handled just because you’ve invested in a state-of-the-art cell phone signal booster. If there weren’t any cell phone signals in that area before you got there, the booster isn’t going to create one. In a nutshell, a cell phone signal booster can only amplify an existing, weak signal, not create one!

This cell phone signal booster constitutes three main components: an external antenna, an internal antenna and an amplifier. There is also a cable, which connects all these parts. The external antenna is one of the most crucial components as it helps to draw a signal from the closest cell phone tower that supports your mobile network.

The repeater amplifier then takes this signal and makes it stronger. Amplification is usually measured in decibels (dB). A 3 dB amplification doubles the strength of the signal, which means that 6 dB provides twice the signal strength of the 3 dB one.

An internal antenna, which is the last element, also plays a role in this process. It helps in re-broadcasting the newly amplified signal. By this time, your mobile phone will be able to identify this stronger signal, meaning that you’ll be able to load pages faster and experience fewer dropped calls. As for the cable, it’s advisable to choose a short, high-quality cable.

Good! Why Do I Need a Cell Phone Signal Booster?

If you don’t have strong enough signal, your calls will drop occasionally. But why does this happen? The most likely reason is that you’re making your calls when you are too far away from a cell phone tower. Another reason could be that there are too many obstacles in the path of the signal. Common barriers that impede signal strength include trees, hills, mountains and buildings.

Is there an alternative to using cell phone signal boosters? I’m afraid not. The best chance you have of improving your cell phone reception is to invest in a signal booster if you don’t want to relocate. The only exception is if you’re in transit, that is, if you’re driving a car or sailing a boat. When you’re on the move, the external antenna won’t be accurate because of the fast locomotion of these transportation means.

Before rushing to buy a cell phone signal booster, first establish the size of coverage. Some boosters can only cover a small space while others cover larger areas. The trick here is to go for a booster that covers at least 10% more than the estimated coverage. This way, you have guarantee that the booster will work perfectly for your space.

Some manufacturers design boosters specifically for home use. Such boosters have the capacity to cover big properties. Some can even cover commercial properties like work buildings, forested areas and more.

When it comes to the external antenna, there are two main variations- the omni and yagi. The omni is a good example of a multi-directional antenna, meaning that it can pick up strength in all directions. Conversely, the yagi points in one direction. So if your cell phone tower is located north, you should ensure the yagi antenna is pointing north to receive a more powerful signal.

We also have two main types of internal antenna- dome and panel. A panel antenna is one designed to amplify signal across numerous floors. This antenna points in one direction. In contrast, a dome antenna is often perched on a ceiling and it gives equal strength to all the floors below. Dome antennas are not the best option for operating on multiple floors.

The benefits of a cell phone signal booster

  • You will experience fewer dropped calls and a better reception. With a signal booster, you will be able to hear the person on the other end of your call clearly, and vice versa.
  • A reduction in the frequency or size of dead zones. This will come in handy if you drive frequently on such areas.
  • Reliability in data uploads and downloads- with this device, users are able to download and upload media content much faster. You can also stream music and videos seamlessly.
  • Faster texting- you won’t encounter any more lags when sending and posting messages.
  • Long battery life- when you invest in a cell phone signal booster, it means that your phone won’t be forced to work as hard as it won’t be reconnecting to weak signals anymore.

A simple system for home or car

When choosing a cell phone signal booster, you will have to choose from two main types. We have a signal booster designed for car, and another for home or office use.

The first type is usually attached to the car or truck magnetically. The internal antenna of this booster improves reception throughout your automobile’s cabin.

A booster designed for home or office use, will be mounted outdoors. The antenna, in this case, boosts coverage throughout one or more rooms.

Understanding Bars: They Aren’t Just Signal Strength

If you ask anyone what the bars in their cell phone represent, they’re likely to say signal strength. However, this is not the only thing that these bars indicate. Essentially, the signal bars show two features:

  • Signal strength- this shows just how strong the cellular signal is when it reaches your cell phone. It’s usually measured in dBm.
  • Signal quality- measured in dB, this is a ratio of the real source of the signal to the sounds and interferences that are also reaching your phone.

Signal quality will cause the number of bars on your cell phone to decrease in the same way that signal strength would. Familiarizing yourself with this concept is crucial before you can embark on installing a signal booster.

The vast majority of cell networks use LTE networks both for calls and data transmissions. In any LTE network, the signal strength and quality are known as “RSRP” and “SINR”.

Reference Signal Received Power (RSRP) -the strength of the LTE’s signal is measured using RSRP. A strong signal ranges at about 70 dBm RSRP while for a weak one, the signal strength is about 100 dBm RSRP.

Signal to Interference plus Noise Ratio (SINR) -The quality of the LTE’s signal is determined using SINR. A good signal will have SINR of more than 10 dB while that of a poor-quality signal will be less than 5 dB.

Understanding Bars: Causes of Weak and Noisy Signal

Inter-cell Interference

One thing you’ll notice about recent cellular technologies is that they all utilize identical frequency bands when transmitting signal from their towers. As a result, if your cell phone is in close proximity to two or more towers that have almost the same signal strength, one will end up acting as a barrier or interferer to the tower you’re trying to link to. This will in turn cause low signal quality. Inter-tower interferences are one of the main culprits for weak signals, particularly in metropolitan areas.

Distance from the nearest cell phone tower

Another factor that weakens cell signals is when they travel through space. Anytime that you’re not close to a cell phone tower, your cell phone signal weakens. The further away you get from the cell tower, the harder it is for your phone’s internal radio to “hear” the tower’s signal.

Building materials/vehicle construction

Some kinds of materials, especially those used for construction, can weaken your cell phone’s signal. These include items like concrete, metal, drywall and low-e glass. This explains why some boosters are recommended for basement and others for using within an office.

Geography and nearby buildings

As mentioned earlier, your location has a significant impact on the strength of your cell phone’s signal. So that if you are near a tower, the signal will be strong. But if you’re exploring the nearby mountains and valleys, the signal is going to be weak.

How a Cell Phone Signal Booster Works

The way a signal booster works is by amplifying the signal reaching your cell phone from the closest tower. This cell signal booster consists of three main parts:

Donor antenna

The purpose of this component is to transmit signals between your mobile phone and the tower. It’s usually installed on the roof. However, you may come across some buildings that have directional antenna, which is even more efficient. With this antenna, you can aim at a specific tower; this strengthening the signal by minimizing interferences.


This is sometimes referred to as a “bi-directional amplifier” or BDA. As its name suggests, this component helps in amplifying the signal reaching your cell phone and the one going back to the tower. A coaxial cable is used to connect this amplifier to the indoor antenna and donor antenna.

Indoor antenna

This component serves to distribute signal to as well as receive a signal from your mobile phone. There are two common types of indoor antennas namely: dome antennas and panel antennas.

Why You Have Bad Cell Signal

If you’re experiencing bad cell phone signals, they could be caused by one of these factors:

Distance from the Cell Tower

The signal in your cell phone is usually broadcasted from a tower set up by your carrier. If you’re close to the tower, your cell signal will be strong but if you’re very far away, the signal weakens. If the strength of the signal is too low, you won’t be able to make any calls ot even transfer data.

Obstacles in the Way

Another factor that weakens cell signal is the presence of obstacles. Cell phone signal cannot penetrate through massive bodies such as mountains or buildings. So the only way the tower’s signal will reach you is if it bounces off on the obstacles and reaches you via reflection. By the time it reaches your cell, it will be too weak, and is likely to fluctuate up and down.

Combinations of Causes

Your poor cell signal could be caused by multiple factors and not just one. It’s likely that your cell signal is weak not only because your rural home is situated miles away from a cell tower but also because your house consists of sheet metal walls that are preventing any signal from penetrating into the building. So when looking for a feasible solution, find out whether your weak cell signal is being caused by one or more factors.

How to choose

Even though most cell phone signal boosters look identical, there are a few things you should keep in mind.

What type of wireless connection do you need?

Some signal boosters are designed to transmit 3G broadband internet only, others 4G and a few can transmit both. The main difference between the two is the speed of transferring data. So if you’re depending on your cell phone exclusively for internet access and own a 4G-compartible phone, then you should go for a 4G booster.

For a home/office system, how many rooms do you need coverage for?

Cell phone signal boosters have varying strengths. Some provide coverage for just one room while others are powerful enough to provide coverage for a whole floor. Remember to check the estimated coverage of the booster before purchasing.

How many users are there?

If you have multiple devices, which you intend to use with the system simultaneously, then you need to ensure that the booster can handle such traffic.

Consider a multi-bandwidth device

Whether you’re buying a booster for your home or office, chances are that you already have gadgets that operate through wifi or wirelessly.By investing in a multi-bandwidth boost, you can switch between frequencies so as to minimize the disruption from the other devices.

Wrap Up

It is no secret that your cellular device signal depends on your proximity to the cell tower. If you go too far away, this signal weakens. To improve your reception, you should invest in a cell phone signal booster. This handy device helps in reducing the number of dropped calls and increasing the data transmission speed.
