Nikrans NS-250GDW Overview

Triband mobile repeater Nikrans NS250GDW amplifies mobile signal at three different frequency bands simultaneously - DCS 1800MHz, GSM 900MHz and 3G 2100MHz. This repeater is valid for all mobile networks across the European Union, Asia and Africa.

This mobile broadband booster is designed for middle-sized indoor locations up to 250m2 (2700 ft2), so it will be ideal for private houses, offices, shops and cafes located in underground or rural areas.

Nikrans NS250GDW has some specific features that make its work more effective:

  • Automatic Level Control, ALC, automatically fixes repeater output level depending on the input signal strength.
  • Automatic Gain Control, AGC, intelligently adjusts gain level according to signal fluctuation.
  • Manual Gain Control, MGC, permits users to regulate gain manually basing on individual signal reception conditions.
  • Shut-Off function helps the booster avoid self-oscillation caused by excessive incoming signal strength or improper installation.

The major feature of the Triband model is its multifunctional capability. The tri band repeater ns250gdw improves phone calls on 900 and 1800MHz; boosts 3G Internet on 2100 and 900MHz, and optionally supports LTE connection on 1800MHz. So thanks to NS250GDW you will get reliable phone calls, 3G and 4G connection.

This mobile broadband booster is CE and RoHS certified, consequently it meets the European quality and safety legislations.

NS-1100GD for Velcom signal problems

The signal in our office used to be rather unstable. And our carrier could not help us. So we decided not to waste time and to resolve the problem on our own by getting a mobile repeater. The obtained results exceeded our expectations. I send you a few images for your reference.

(Portugal)  ·  Purchased Nikrans NS-250GDW  ·  April 4, 2016

Just installed this booster. Lost some time to find the best location for the antennas and to run the cabling inside the house, but once installed the booster did not keep me waiting for the result – 5 bars instead of 2. Plus, 3G Internet without interruption. Highly recommend this!

All features function as advertised. Covers the whole house and a bit of terrace – nice for the summer bbq’s))

Delivery took a week, but that is no big thing providing what I got.
