How it works:

The StellaOffice-GDW tri band repeater ensures that all operators are amplified for Voice(GSM) and 3G data.

If your operator transmits 4G at 1800Mhz, 4G will be amplified too.

Used for large buildings where the indoor coverage is weak or non existent. It amplifies 900Mhz, 1800Mhz(4G) and 2100Mhz ( 3G).

The StellaOffice-GDW is very useful in offices where there are many people on different mobile operators. Some people will be making calls and others will be using 3G data and 4G data. All options are covered with this repeater, so  you don’t need to think about which frequency to use.

The frequencies.

  • 900Mhz: Great for voice calls. And for all phones, including older model phones.
  • 2100Mhz: great for voice calls, and fast 3G data.
  • 1800Mhz: great for 4G.


This repeater has 4 indoor antennas. Each antenna will amplify 1000Mt2 (~3 rooms), so in total, this kit provides up to 15 rooms coverage.

Quick install guide

EN_what you get_office_800 StellaOffice_diagram1

We recommend doing a "loose" install first, so that you can test where best to place your cables and antennas.

  1. Install the outdoor panel antenna in a location where there is good mobile signal. (usually this is the roof).
  2. Attach the 15m cable to this antenna and run it down inside the building to the Stellaoffice repeater.
  3. Attach this cable to the repeater. Then attach 1-4 cables to each of the  ports the the repeater.
  4. Cable from these ports to 4 locations that require coverage.
  5. Plug in the power supply.
