An Overview of Mobile Phone Signal Booster

A mobile phone signal booster, also known as a repeater or amplifier, mainly consists of three elements: indoor antenna, amplifier, and external antenna. These components collectively form a wireless system that increases cellular reception. This article particularly talks about how these mobile phone signal boosters work and what types of boosters are available on the market.

A General View

A mobile phone signal booster is generally a signal amplifier system where the booster adds or gains power to the reception in various directions. The maximum gain, even in cheap signal boosters, differs depending on the application. The outdoor antenna works as a receiver and a transmitter to transmit the signal to a cell tower with higher sensitivity and power. Typically, the power gain is not below 9 dB and can exceed 10 dB. The electrical conduit of the system consists of a coaxial cable that minimizes transmission loss.

The ultimate goal of a mobile phone signal booster is to take the current phone call signal around your home, workplace, or car and amplify it. The signal is amplified and retransmitted to the area with a weak signal or no reception. In addition to an amplifier and external antenna, there are systems that come with an amplifier and internal antenna as a single unit making them great for signal boosting indoors. But in most cases, the three components are separate and also come with other optional devices like Attenuator to reduce the unwanted frequency, a Splitter, and a power surge protector.

How does a Mobile Phone Signal Booster Work?

Cell phone signal boosters for other carriers are used if signal reception in a particular area is weak. Mobile phone signals become weak due to various reasons, such as distance from the tower, trees or buildings in between, hills, etc. In such cases, signal boosters come into play. You should keep in mind that a mobile signal is nothing but the strength of the signal that is sent to a mobile phone.

First of all, the outdoor antenna captures the reception of the mobile phone. The booster then amplifies and retransmits throughout the house or building via the indoor or indoor antenna. This process results in an increased mobile signal in remote locations and weak signal zones. You can enjoy better call quality and faster internet browsing after boosting the signal. This process can be applied to all mobile networks like GSM, LTE, CDMA, EVDO, UMTS, HSPA+, etc. In simple terms, you can boost your 2G, 3G & 4G signals for your mobile network.

Another benefit of the improved connection is a significant increase in battery life, extending from 150 to 180 minutes of additional talk time. You can choose a cell phone signal booster at our website that works with all kinds of cellular devices.

There are several types of mobile signal boosters available in the market. But, not all signal boosters are the same and they have different capacities and functions.

1. Analog Signal Amplifiers / Bidirectional Amplifiers

Most signal boosters are essentially analog signal boosters. Analog signal boosters use traditional technology to amplify all cell phone carrier frequencies. Analog signal boosters also work as broadband (broadband) boosters and are usually sold together with an outdoor antenna kit and cable. However, installation is required for such devices. Sometimes analog signal amplifiers are also called bidirectional amplifiers or BDAs. BDAs are required for many localities under the law to allow their first responders to maintain contact in different areas for emergency situations. Two-way amplifiers are used for two-way radio use.

2. Smart Signal Boosters

Smart signal boosters are a relatively new form of mobile phone signal boosters. The smart signal boosters use powerful baseband digital processors that first remove coverage and then continue retransmission. Smart signal boosters come with gains of over 100 dB, while analog amplifiers in the same league have gains of 63 dB to 70 dB. Smart signal boosters come with many additional features like an internal antenna inside the box, no need for outdoor antennas, and plug and play option. Due to modern technology and additional features, smart signal boosters are more expensive than analog boosters.

But, these smart signal boosters are good for vehicles, as they cover a very small area. Whereas the analog signal boosters cover larger areas of up to 5000 square meters or even more.

Reasons for Weak Signal

A weak signal can be the result of a few different factors. Some of them are discussed below.

Distance Between Your Vehicle/Home and the Cell Tower

One of the main reasons for a weak mobile signal is the distance of your home or office from the nearest mobile tower. The closer you are to the cell tower, the better signal you will receive. Likewise, the further you get from the tower, the worse the signal will be.

Interference from External Sources

External interference can also affect your mobile coverage. Cellular signals are generally radio waves that travel a long distance to reach your phone. For the waves to be transmitted effectively, a clear line to the operator’s tower is required. Aside from that, other external disturbances like skyscrapers, mountains, trees, and elements like snow, rain, and thunderstorms weaken the signal reception.

Interference from Within

Internal interference also weakens the reception of cellular signals. Thick building materials such as thick concrete, layers of brick, glass, and metal, radiant barriers, magnetic and electronic clutter, and conductive materials that block or weaken signal reception are also responsible for poor signal reception. There are chances that the signal strength is very strong and the tower is close to your location, but you will receive a poor mobile signal due to internal interference.

What to Consider While Buying a Mobile Signal Booster

There are a few important things that you should know before you buy a mobile signal booster. If you know these you will certainly be able to make informed decisions and buy yourself the right type of mobile signal booster.


All the mobile signal boosters available in the market are not of the same quality. The best quality signal boosters are CE-certified, RoHS compliant, and also comply with the guidelines of the Telecom Regulatory Authority of the country in question.


Since the mobile signal boosters work on specific frequencies then it is important to make sure that the mobile signal booster you are buying won’t interfere with other radio signals in the area. Or you may land yourself in trouble. So choose the signal booster that works on the exact same frequency band that your cellular service provider uses to provide their services.


Durability is another thing that you need to make sure of. The low-quality signal boosters are not durable and may start to malfunction in a few weeks or months. So, choose only the signal boosters that are durable and come with a manufacturer’s guarantee for any type of malfunction.


The good quality signal boosters don’t require any kind of maintenance as they don’t have any moveable parts in them. So, choose the ones that don’t require any maintenance.

Frequency Bands

Cellular service providers in different countries use different frequencies to provide their cellular services. Before you buy a mobile signal booster make sure the signal booster you are buying works on the same frequency band that your cellular service provider uses to provide their services.

Working Conditions

Bad weather can significantly affect the signal reception. So, does the signal boosters. But, there are mobile signal boosters that work in all weather conditions and in all terrains.
