NS-2500GD is a dualband repeater that amplifies a mobile signal at two frequencies, GSM 900 MHz and 1800 MHz at the same time, and is apt to drastically ameliorate the GSM signal reception of all the operators in the UK. It is effective for amplifying low signals in spacious areas that otherwise are not easily covered, such as giant shopping malls, offices, supermarkets, underground parking, and conference halls, etc. The maximum coverage area is up to 21,600 ft2 (2000 m2).

Moreover, if your provider uses these frequencies to deploy its 3G/4G Internet network in your neighbourhood, you will get an added advantage of getting these signals of high strength.

Here are some of the most important features of this booster:

  • Shut-off function is necessary for preventing repeater from getting damaged due to strong external signals or incorrect installation.
  • Automatic Level Control (ALC) is used to control repeater output signal for preventing network interference.
  • Automatic Gain Control (AGC) is useful to automatically control incoming signal strength.
  • Manual Gain Control (MGC) is meant for advanced users who prefer to regulate gains manually.

The compliance with the internationally recognised CE and RoHS standards ensure that the deivce is 100% safe to use and doesn't affect your health and environment. On top of it, you will benefit from a 3-year warranty.

Click on the "Buy Now" button andforget completely about dropped calls and slow Internet for good!

Some UK's providers also use 900 MHz frequency for 3G Internet connection. So if your mobile operator supports 3G at 900 MHz, this booster will improve both your phone calls and Internet connection.

How it works

4G Mobile Signal Booster Nikrans NS-2500GD is not just another powerful device, it is also a really smart one. While its task is to receive, boost and spread the signal, it can automatically control the strength of the signal that is caught as well as the level of the signal that is spread. These important features ensure the safest functioning of the device and its highest effectiveness. If a user has deep understanding of the working principle of the device and wants to regulate these settings manually, such an option is also available.

Shut-off function that NS-2500GD has helps to minimize risks of damages and errors that can be caused by mistakes in installation or too intensive incoming signal.

Case Studies

Kieran Chun, Norwich

We were advised a suitable model.

Frankly speaking, it wasn’t an easy task to choose the best model among all the devices available at Mobile-signal-boosters.co.uk. They offer a huge variety of boosters depending on the indoor coverage and operator’s frequencies. Fortunately, Mobile-signal-boosters.co.uk’s manager explained us everything we needed to pay attention to and helped us choose the most suitable variant.

Timothy Hassette, Ringwood

The whole set up is not at all complicated!

I would like to thank Mobile-signal-boosters.co.uk for fast shipping and high quality product they have sold me. The company provides a full set for immediate installation with all necessary details and mountings. They also have sent me a user’s manual with detailed information regarding the set up process and the main features of the device.

Kenneth Nailor, Folkestone

Much needed device if signal problems persist.

I decided that it was time to change the situation with bad signal coverage for better and a signal repeater would be the best decision for our customers to enjoy their 3G internet and GSM connection. It would for sure pay back in a couple of months and, overall, be a convenient thing no matter what.
