Cellular signal amplifiers are devices that capture mobile phone signal traces, amplifying them and distributing them in an environment to several devices.

These devices are indispensable for remote areas or even in places in large centers where the telephone signal is low. As we saw above, there are several types of models, differing in size, range and frequency. So it can be a challenge to choose the model that best suits your mobile device and that is compatible with your operator.

We know that not everyone in a family or group of friends uses the same carriers and cell phone models. Therefore, it is also important to take into account the frequencies at which cell phones work.

They can work in dual-band, tri-band or quad-band, the latter being the most complete technology. With this in mind, it is necessary to choose a cellular signal amplifier that aligns with your device and your operator.

The following are the advantages and disadvantages of a cellular signal amplifier:

Purchasing Criteria: How to Compare Cellular Signal Amplifier Models

When comparing products, it is very important to understand the main aspects of the models. Therefore, we cannot be carried away by advertisements. It is much more prudent to research and pay attention to the details that matter.

To assist you in this, we would like to conclude by pointing out to you the main aspects to observe when making your choice:

• Frequency
• Reach
• antenna dBi
• Size and weight

Next, we’ll talk in detail about each of these four factors.

Frequency

Mobile operators have different frequencies, and the same operator may even operate in different bands in certain cities and states. It is also possible that different operators use the same frequency.

We currently have 3 types of technologies:

• 2G : In since the 90’s, GSM (Global System for Mobile Communications) has been used, which is mainly used for telephone calls. With regard to the internet, this technology leaves much to be desired. Their frequencies are 900 and 1800mhz.
• 3G : Uses WCDMA or CDMA technologies, it is the most popular. It has speeds starting at 200kbps and is at frequencies 850 and 2100mhz.
• 4G : It is becoming more and more popular, using the LTE (LongTerm Evolution) standard. It delivers speed and performance superior to 2G and 3G technologies, with availability on frequencies 700, 1800 and 2500mhz.

Unfortunately the amplifiers are not compatible with all frequencies, so it is very important to check the compatibility of your operator, the technology of your telephone plan and the frequency delivered by the amplifier of your choice.

Reach

Range is the ability to distribute signal across amplifiers. In this case “the more the better”.

However, it is also important to analyze the environment where you will install the cellular signal amplifier, as barriers such as walls and plumbing negatively influence the signal distribution.

Information on the scope of the product can be found in the description on the sales websites, or on the packaging. Manufacturers generally specify how many square meters the device can cover.

This measurement will depend on the space you need the device to cover. Calculate the environment in square meters and always opt for a device that has a range greater than your space.

If you have an area of ​​1,000m2, for example, choose an amplifier that reaches above that. This way you won’t find any problems, especially if the location has walls that can disrupt the signal.

antenna dBi

Decibel is a measure to quantify the sound and its waves. It is also used to measure power loss in antennas.

The measure that matters most in the case of antennas is the dBi, isotropic decibel, which is important for measuring the antenna gain, which is what evaluates the signal strength.

Therefore, we should look for amplifiers with antennas that have a higher dBi index to have a better experience.

When you add the right frequency with high range and dBi, you should have no problems with your cellular signal amplifier.

Size and weight

This aspect has little influence on the performance of the device, except for the detail that the smaller and more portable ones generally have less range and power.

It is important to mention the practicality for installing, uninstalling and moving the device if you want to use it in more than one place. In this case, the smaller and lighter the cell signal amplifier, the better.
