The Nikrans LCD-300GDW is the latest triband repeater model that amplifies the mobile signal for GSM voice calls and 3G high speed Internet. One of the most useful features of this model is the LCD screen providing several options such as setup tutorial, error notes and solutions, and system information.

As for GSM voice calls, it supports two frequencies, 900 and 1800 MHz respectively. As far as 3G signal amplification is concerned, the LCD-300GDW is programmed to 2100 MHz. Moreover, if your operator's 4G network is deployed at 1800 MHz, you will automatically get your 4G signal amplified. Nikrans LCD-300GDW is capable of covering an area with a range of approximately 300 m2 (3300 ft2), making it the ultimate choice for villas, offices, schools, shopping centres, large apartments, and underground pubs.

Here are some of the most prominent features of this booster model:

  • A smart LCD display. From setup instructions to error solutions and signal levels, you get all types of important system notifications regarding the repeater.
  • Sleep mode. The device goes to sleep mode when no activity over the network is detected and turns back on as soon as you start making calls and browsing internet.
  • Auto signal control function. The system has a built-in feature of automatically adjusting the gains level as per the incoming network signal. As a result, you will not have to face the inconvenience of adjusting gains manually.
  • Certified by CE and RoHS. LCD-300GDW is a high-quality device certified for its quality and safety standards. Hence, it is 100% safe to use for humans and has no known impact on health and environment.

How it works

Given the fact that Nikrans LCD-300GDW has an LCD screen, you won’t have any difficulties with its installment and setting up. On the screen you will see useful tips and system data including errors and performance indicators.

The telephone signal booster set includes a repeater and two antennas with coaxial cables. The external antenna is intended to be fixed outdoors and the second antenna is to be placed inside the building and has a ceiling mount. Each antenna has a cable to be used for its connection to the booster box. With your order you will receive cables of a standard length (20 m cable for your outdoor antenna, and 5 m cable for your indoor antenna). Nevertheless, you can always order an extra cable of another length if needed.

Case Studies

David Robertson, Blythe Bridge

O2 signal problems were so frustrating for me!

After I moved to my new house I was dreaming about for a while, I found out that no one warned me about O2 signal problems we have in this region. The satiation with the signal was actually pretty understandable, since there were a lot of hills around my house, and the nearest cell tower was still too far for me to get a decent signal, so was my only hope to get rid of these troubles.

Installation is fairly simple

Even though I expected that I would have to hire a technician and pay extra money, I was able to put the delivered signal repeater together all by myself out of mere curiosity. Just as it was promised – few easy steps, a detailed user guide, nothing difficult. The only difficult thing was to mount the booster box onto the ceiling, but it was my personal choice. And still, I succeeded! And I enjoyed the process.
