FAQ

How does a mobile phone repeater work?

A mobile phone repeater is a bi-directional device that catches mobile signals from nearby tower, boosting it multiple times, and broadcasts them within the coverage area. This has 2 added benefits. First, it works by improving your signal reception and second, by amplifying the signal sent from your smartphone. The primary purpose of using a signal booster is to improve network coverage for faster 3G, 4G/LTE, internet streaming, social media and browsing, and GSM voice calls. For more details, please visit the How Mobile Amplifiers Work page.

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

Starting from as low as 5, there is really no limit to the amount of smartphones and 3G, 4/G LTE network connections that can be amplified at the same time, but with our recent tests with an NS300GW, you can support over 100 smartphones simultaneously. It doesn’t matter whether you are using an iPhone, Samsung Galaxy S7, S8, Huawei, LG or a Motorola smartphone, you will always receive the best coverage using our signal boosters. The only way to make boosters work is by not moving out of the network coverage.

We understand that our customers are very concerned about their health and safety by using these signal boosters. We also understand that consumers think that these devices emit harmful radiation.

Choosing a Booster

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

Smartphone signal repeater models vary depending on coverage, capacity, dBs, and frequency types. Hence, it is recommended to read our Buyer's Guide page on choosing the right type of booster. You can also read more technical info in the manuals, which can be found on the relevant product pages. And, sure, do not hesitate to get in touch with us while choosing a booster.

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

To help you in finding the most appropriate model based on network compatibility in your area, use our search engine. We have designed it to minimise your time and effort in searching for the ultimate booster. To find out which mobile phone repeaters are compatible with your country and operator, just select your country and you will see the most suitable options. Thereafter, you can easily buy only from a list of boosters that work within your country and mobile operator. 

Installing and Using

Can I install a repeater system without a technician?

Every mobile phone booster is easy to install without requiring any sort of technical knowhow. It is suggested that you spend some time familiarising yourself with the booster by reading the manual. After going through the manual, you can easily install it without any technical help. Browse our How to Install page that we have specially designed for non-techies. However, feel free to Contact our technical support for professional help if you are unsure. 

Can I use a 3G mobile phone repeater for improving voice calls?

It depends whether your network supports voice calls and 3G on the same frequency. If yes, then the repeater will boost voice and 3G signals. Nevertheless, 3G signal booster sets are generally designed only for improving mobile internet, not voice calls.

Most modern boosters at Mobile Signal Boosters are either dualband or triband, meaning that they support amplifying GSM and 3G/4G LTE signals at the same time. To buy from one of these models, you are invited to visit our GSM mobile signal booster page or use our Search engine

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

Absolutely, we provide certified amplifiers that amplify signals regardless of the number of obstacles in your home or office. However, it is important that you choose a reliable repeater that provides adequate network coverage across multiple rooms and floors. Choosing the best model may become more complicated if a building has concrete walls or metal partitions. In such situations, we suggest you to contact our managers to choose the best repeater for your individual situation and needs.

What should be the maximum length of the cable between an internal antenna and a mobile phone repeater?

The length differs depending on the model. For powerful repeaters such as NS5000, the cable length is approximately 15-20 metres; whereas for boosters such as the MA300, it is around 5-10 metres. It is better to use the cable provided with your installation kit to avoid any type of signal loss.

What should be the maximum length of the cable between an outside antenna and a mobile phone repeater?

It also differs for most of the repeaters. For powerful repeaters like NS5000 or NS2500 the maximum length can be 25-30 metres; whereas for smaller models like MA300 or NS250, it is 15-20 metres. However, we strongly recommend to use the standard cable provided with the kit to avoid any type of signal loss.

How to check precise signal level in dB?

To interpret signal level with maximum precision, you’ll need to switch your smartphone into Field test mode (FTM). It’s a free application available in the App Store and Google Play Store requiring no extra setups for iOS and Android operating systems respectively. For each OS, the following steps need to be performed:

  1. iOS. Type * 3001 # 12345 # * and touch Call
  2. Android. Type * # * # 197328640 # * # * to activate
  3. Windows. Type # # 3282 # and start.
  4. Blackberry. Press TOOLS, SETTINGS, STATUS or OPTIONS, STATUS.

It is important to turn off WiFi for getting the right parameters of 2G, 3G and 4G LTE. If you are unable to search for the Field Test Mode on your smartphone, contact us to help you out in this situation.

How to aim an outdoor directional antenna correctly?

It is vital that you install the external antenna correctly in the following order to get the best network reception:

  1. Unbox the booster kit
  2. Setup, and turn on the system.
  3. Have at least 2 persons for the installation process, one for aiming the antenna at roof, and the other for installing the device and measuring results.
  4. One person should be on the roof to aim antenna in a certain direction. The other should wait every minute to check signal level.
  5. The person on the rooftop should then rotate the antenna 1/8th of the way around, equalling 45 degrees. The person inside does the same procedure with signal testing.
  6. Repeat the entire process 8 times until you try all 8 directions, every 45 degrees.
  7. Compare the results– the position that shows dB numerical value close to zero, is the result that you want.
  8. Fix the antenna in the direction that shows the lowest dB value.

Please, note, that the external antenna should be aimed away from buildings, transmission cables and any obstacles that could impede the results. 

What do the dB signal testing results mean?

As discussed earlier, a Field Test Mode is important to determine your antenna’s position. Here is a guide to help you out:

You should aim ideally for -79dB for the best indoor signal amplification.

Troubleshooting

Does Nikrans 3G repeater support all network operators?

Every Nikrans 3G repeater is compatible with the most common 3G 2100MHz network frequencies, such as:

1. WCDMA
2. UMTS
3. HSPA
4. H+

For most of the network carriers in Africa and Europe, 2100 MHz is the most commonly used frequency supporting 3G.

It is to be noted that some network operators perform routine upgrades in Europe. As a result, it is important to confirm from your wireless carrier on the 3G frequency that it supports.

In addition to this, 3G repeaters can only be used for amplifying 3G signal. For improving voice call clarity, feel free to browse through our wide range of GSM phone repeaters.

How would I know that my 3G repeater is working in the right way?

Every 3G mobile phone repeater comes with LED lights and here is each one of them described:

It is important to note that every repeater differs in terms of LED lights and notifications. For more accurate information, please refer to the operating manual.

When I attach the cable to my AT4000 3G, the red light switches off. How to resolve this issue?

The primary reason for this to happen is due to poor or incorrect installation. To fix it, make sure that all components are installed in the following order:

1. Mount repeater.
2. Connect antennas to the repeater.
3. Plugin and turn on the power adapter.
As precautionary measures, we would also suggest you to go through our manual for the AT4000 3G.
