NS-1100GD is a dualband model that amplifies GSM mobile signal at two different frequencies simultaneously, 900MHz and 1800 MHz. Both of these frequencies are used by network operators in the UK and in the rest of Europe. The booster is effective for large areas of up to 1000 m2 (11000 ft2), providing unsurpassed coverage in villas, parking lots, restaurants, and supermarkets, etc.

The NS-1100GD repeater is an ideal solution for improving GSM voice signals. In case your mobile services provider operates at 900 MHz for 3G and 1800 MHz for LTE networks, the NS-1100GD repeater will also effectively boost the respective signals at these frequencies.

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

  • Automatic Level Control, or ALC, controls repeater output levels for better signal reception and amplification.
  • Automatic Gain Control, or AGC, intelligently regulates repeater gains based on incoming signal strength.
  • Manual Gain Control, or MGC, allows you to manually adjust repeater gain, and is an ideal option, if you are a technical user and want to adjust the device according to your needs.
  • Shut-off function helps to protect the repeater from self-oscillation, improper setup or excessive incoming signal, whereby the device turns off to prevent any damage.
  • CE and RoHS certificates proving that the booster meets international safety and quality standards.

It is time to end your network woes. Buy the Nikrans NS-1100GD now and say goodbye to dropped calls and slow Internet forever!

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

How it works

This extremely powerful 4G Mobile Repeater Nikrans NS-1100GD that is able to amplify mobile signal within the indoor area of about 1000 m22) can be a good solution for those who are looking for a device that will be appropriate for large office buildings, private houses, hotels, hypermarkets, etc.

Thanks to functions of level and gain control, the device can demonstrate the highest effectiveness in various conditions resulting from the peculiarities of the location.

While installing this device it is important to remember, that for covering several floors simultaneously (especially if we are speaking about more than two floors), it is recommended to use additional indoor antennas and splitters that will help to distribute the amplified signal across all the area that you wish.

Good Service

I was really impressed by the way the manager accepted my order. He provided detailed consultation regarding the installation and the functioning of the model. Keep on doing like that and you will have even much more thankful clients.

Dear Emily, thank you very much for the feedback and nice words. We were glad to be useful! Best regards, Support team.

Not Bad

In general, the device isn’t bad. It’s rather unsophisticated but effective at the same time. The only point was that the cable for indoor antenna was a little bit short for my area, but this problem was easily solved.

Dear Michael, thank you for the review. We would be glad to help you again. Best regards, support team.

Looks Reliable

With the help of this device I managed to get decent connection in my restaurant. The model is very compact and stylish. Fortunately, it doesn’t stand out in my interior. The visitors only have noticed that the quality of calls and Internet became much better.

Dear Jacob, thank you very much for the review. We are glad that your visitors are satisfied. Best regards, Support team.

Satisfied with the purchase so far

We desperately needed to do something with mobile signal in our warehouse. It was just unbearable to talk inside - calls interrupted or went straight to mail box, had to come out to call. That I think because of a metal roof. We purposefully chose a more powerful model than the surface required - just to make sure to pull at least any signal inside. Now we have 4 bars inside, calls don't drop and we can even use our mobile Internet.

Dear Steven, thank you for the feedback. Hope to see you at our store again. Best regards, Support team.

Good for Improving GSM and 3G

I bought it to improve weak signal inside my café - my customers constantly complained that it was impossible to talk over the phone and to do anything while using data. The device perfectly fulfils its tasks. But be attentive - have to find a place for outdoor antenna with really good signal.

Dear Ross, thank you for the review. Feel free to contact us in case you need our help. Best regards, support team.

Case Studies

Ralph Riordan, Clydebank

Thanks for the help with a signal booster!

Mobile-signal-boosters.co.uk’ technical support were the ones who ensured us that our signal problems could be solved easily even despite the fact that the reason of our issues was a large hill blocking the signal away from us. And they were absolutely right about that. Thanks to Mobile-signal-boosters.co.uk, there are two more happier people in the world who are able to use their internet despite their landscape circumstances.

Samuel Truter, Middlesbrough

Assembling was rather quick and trouble free.

The assembling process was really very easy and fast. I placed the outer antenna really high onto the roof and made it face the direction of the nearest BT Mobile cell tower to maximize the chances of catching good BT Mobile signal. Then I connected it to the booster box, that I mounted on the wall near the window and plugged in the inner antenna. After that I simply had to plug the booster box into the power socket to see if it all works.

Mary Shoreman, East Kilbride

The calls do not interrupt, browsing is fast!
