NS-2500GDW is your ultimate answer for boosting GSM and 3G signals in areas with poor connectivity. The cellular phone signal booster for home is distinguished by the tech design and the latest software that enables it to cover areas of up to 2000m2 (21500 ft2). It is suitable for providing unsurpassed GSM and 3G coverage in spacious villas, offices, supermarkets, conference halls, and underground areas, etc.

The booster amplifies signals at three frequencies at the same time: GSM 900 MHz & 1800 MHz and 3G 2100 MHz, all of which are compatible with network providers in Ireland and the United Kingdom.

Alongside, the booster is also able to amplify 4G/LTE signals at 1800MHz on condition that your provider supports 4G at this frequency.

Here are some of the most unique features of this device:

  • Automatic Level Control that serves the purpose of avoiding signal interference.
  • Automatic Gain Control for creating favourable signal conditions.
  • Manual Gain Control for advanced users looking to control the gains manually.
  • Shut-off function for protecting the booster from malfunctioning due to incorrect installation or self-oscillation.
  • CE and RoHS certificates for ensuring 100% safety in usage.

Having to stabilize GSM, 3G and 4G connectivity all the time is quite frustrating in areas with poor network reception. Therefore, buy this model now and forget about all the nuisances caused by poor quality calls and slow Internet speed!

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

We highly recommend to follow the principles of its installment. An external antenna is usually mounted on the roof of the building or via a window on the top story. Please pay attention to its direction in order to achieve the highest reception. The indoor antenna should be mounted on the ceiling in order to ensure better distribution of the amplified signal. Both antennas should be connected with a coaxial cable to the base unit. If you want to cover several floors simultaneously (especially for multi-storey buildings), we recommend to purchase additional indoor antennas and splitters that will help to distribute the boosted signal across the remote area.

Helped us with our terrible signal

I’ve had absolutely terrible signal at my new office after our company moved in. As you can tell, this isn’t good for the working process at all, so I had to find the solution, and I found it1 the delivery was really quick, and it was a vital necessity for us. The repeater installation is very easy, no help is required from any other specialists, I actually mounted it onto the ceiling myself. The signal is smooth and stable now!

Hi, Kaiya! It’s good to know that your office can now work having stable signal. Contact us if you have any more questions, we’ll be happy to help! Best regards, Support team.

Useful device

If you want to buy this model, pay attention to the frequencies first, and make sure that you know the exact frequencies that your operator works on. This device is really great and it amplifies the signal very significantly, I now have signal where I previously couldn’t catch it at all. The support team is very friendly and they answered all of my questions. I loved buying from this store and recommend it to anyone who’s reading this.

Hello Aleena! We’re happy that you liked our store and the work of our tech support team. Thank you for writing a review! Best regards, Support team.

Increases the internet signal significantly

Purchasing this signal repeater was a very short and easy way from having to endure constant buffering while trying to watch videos in 360p (and everyone knows that this definition is too low even for the phone screen nowadays) to being able to watch HD videos and use online streaming services. The repeater increases the GSM signal as well, but it wasn’t too critical for us (me and my wife), since we don’t have too many phone calls in our lives. Yet we thought it would be useful to have a booster that can amplify all three signal types at once – just to be sure that everything will be ok. But the internet was the most important thing. Signal troubles were driving us absolutely mad before, because we love to spend our evenings watching stuff online, and we’re really happy to finally have fast enough internet speed in our rural area.

Hello Tyler! We’re very glad that our product helped you and your wife so much. Rural areas can be a lot of trouble for the signal! Best regards, Support team.

Case Studies

Lionel Hansen, Liverpool

There were constant signal problems in our office.

It’s not a secret that practically all business conversations in the modern world take place on the phone. Therefore, good quality of mobile connection plays an important role in any business. When my company changed the location, we noticed that O2 mobile coverage is imperfect there. The only way to refine O2 poor signal in the office was to install a booster.

Warrick Aplin, Bradford

The booster conforms to all our requirements.

When I was choosing an amplifier to improve poor signal in the museum, I paid attention to numerous factors. First of all, that was the coverage area. Secondly, the working frequencies. And finally, the way the device looked like. The model I have ordered covers the whole area of the museum. It is compatible with all operators. Moreover, it is very nice and stylish.

They provide manuals and warranties for all their products which is undoubtedly a great advantage. I received answers to my questions, as well as tips regarding the choice and the installation of the booster.
