How does a cell phone repeater work?

A cell phone repeater is a bi-directional device that catches a mobile signal from the nearest cellular tower and amplifies it to improve the quality of your mobile environment. This has the dual effect of improving your reception and of increasing the signal sent from your phone. The major purpose of using a cell phone repeater is to add extra 2-3 bars to your usual mobile reception. For detailed information, please visit the How Cellular Amplifiers Work page.

How many mobile and 3G connections can support a cell phone repeater at the same time?

The number of simultaneous subscribers is not limited. For example, according to our tests, an NS300GW can support over 100 people using their mobiles at the same time, within an area of 300m2, without any problems. The key factor is not to move out of the area of coverage.

Is it safe to use a cell phone repeater?

Everybody knows that mobile phones emit radiation that harms our health. The good news is that by using a cell phone repeater you can significantly reduce the level of radiation emitted by your phone. Additionally, every cell phone repeater from our store meets the international standards of CE and RoHS.

Choosing a Booster

How do I know which cell phone repeater is the best for my house?

Cell phone repeater models differ in coverage and capacity. Please, read our recommendations in booster choosing on the Buyer´s Guide page. You can also read more technical info in the manuals, which can be found on their product pages.

How do I know what cell phone repeater suits for my country and mobile operator?

For your convenience, we have developed a special Search form. To find which cell phone repeaters are suitable for your country and operator just select your country and we will provide you with all possible options.

Installing and Using

What maximum length of the cable can you recommend between an inside antenna and a cell phone repeater?

The length of the cable differs depending on the model of a cell phone repeater. For powerful repeaters such as NS5000 it is 15-20 meters; whilst for smaller ones such as MA300 it is 5-10 meters. However, we strongly advise you to use the standard length of an inside cable in order to avoid signal loss.

What maximum length of the cable can you recommend between an outside antenna and a cell phone repeater?

The maximum length differs for each cell phone repeater. For powerful repeaters like NS5000 or NS2500 the maximum length can be 25-30 meters; whilst for smaller models like MA300 o NS250 it is 15-20 meters. However, we strongly recommend our customers using the standard cable length (included into the package) for their particular unit for better signal quality.

How to check signal level of my network in dB?

To find out the precise signal level, switch your cell phone into Field test mode (FTM). It’s a phone mode requiring no extra setups and available on most popular mobile OS (operating systems). Depending on your OS, the test mode can be started as follows:

  1. iOS. Type * 3001 # 12345 # * and hit Call
  2. Android. Type * # * # 197328640 # * # * to activate
  3. Windows. Type # # 3282 # and start.

To correctly enable Field Test Mode and read the results, read our detailed guide.

How to aim an outdoor directional antenna correctly?

If you don't know exactly where your operator's base station is located, go through the antenna aiming process for getting the best result. To aim the antenna correctly, follow the steps below:

  1. Setup the entire booster system, including antennas and cables, and power it on.
  2. A person on the roof aims the antenna in a certain direction. The other person inside waits for 1 minute and checks signal level on the phone.
  3. Then rotate the antenna its 1/8th of the way around, which equals 45 degrees. The person inside does the same procedure with signal testing.
  4. Repeat the process 8 times until you try all 8 directions, in every 45 degrees sector.
  5. Compare the results of signal testing – the closer dB parameter to 0, the better booster performance you get.
  6. Fix the antenna in the direction with better signal result.

Note! We recommend mounting the antenna on the side of the building aiming away from the building, which will reduce amount of possible obstacles. For your convenience and acceleration of the process perform the testing in pair.

How to interpret the results of signal testing in dB?

For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The closer dB signal level to 0, the better cell phone reception you’ll get.

  • -105 to -100 = Bad/drop call
  • -99 to -90 = Getting bad/signal may break up
  • -89 to -80 = OK/shouldn't have problems, but maybe
  • -79 to -65 = Good
  • Over -65 = Excellent

Your task is to get at least -79dB signal to ensure reliable communication and strong signal inside the building.

Can I install a repeater system without a technician?

Every cell phone repeater system is quite quick and easy to install. The only thing you need to do beforehand is read the manual. Having read it, you will be able to mount the set without a technician even if you do not have a technical qualification or previous experience. The detailed information about the installation process is complied on How to Install page. However, should some difficulty be encountered, feel free to Contact our technical support for professional help.

Can I use a 3G cell phone repeater for improving mobile communication?

Most modern mobile phones can support different frequency bands simultaneously - 3G for Internet and GSM for cellular communication. 3G signal booster sets are used only for data exchange and are able to improve only the quality of 3G mobile Internet and applications. Even if you can see a 3G icon on your cell phone, as a rule, it is not used for cellular connection. So if you need a cell phone repeater that will improve mobile communication, choose any of our GSM mobile signal booster models (900 MHz) for most European and Asian countries. For other countries use our Search form.

How to find out the frequency of my GSM, 3G or 4G LTE network?

It’s essential to know the frequency of your mobile network to choose the correct mobile repeater. There are 2 ways to find out these data: either using special mobile applications or switching your phone to the Field Test Mode. 

Both methods as well as apps recommendations are described in our step-by-step guide here.

Can I cover several rooms and floors with a cell phone repeater?

Yes, our devices are able to improve the signal in separate rooms and floors. For such a requirement, please choose one of the most powerful models of cell phone repeaters. The process may get more complicated if a building has concrete walls or metal partitions. In such circumstances we recommend that you contact our managers to choose the best repeater for your individual situation and needs.

How do I know that my 3G repeater works?

Every 3G cell phone repeater has LED indicators. The green LED indicates the device status. When it is on, the cell phone repeater is powered on and is working properly. The red LED indicates the 3G signal reception. When it glows or blinks, the device is receiving a 3G signal. Beware of Alarm LED indicating problems in repeater functioning. When Alarm is ON (red), the repeater will not work correctly.

Please, also note that the quantity of LEDs and their indications may differ depending on a repeater model. For more information read a manual to your cell phone repeater model.
