This table is too complicated for me, help me choose the best booster for me.

How It Works

  • The antenna installed on the roof receives mobile signal from all networks. It sends this signal down co-axial cable to the StellaOffice repeater.
  • The repeater boosts the signal to each of its 4 ports. 4 antennas can be installed within the buildinig and connected to these ports.
  • All devices (mobile phones , tablets , laptops, IOT’s)  can now communicate with this enhanced signal.


  • Boosts mobile signal in large buildings
  • Coverage: ~10 rooms
  • Boosts all mobile operators
  • Boosts voice and data (GSM, 3G, 4G and 5G*)
  • Unlimited users
  • Simple and intuitive LED signal indicator
  • No broadband connection required
  • Repeater output power: 5 mWatts  (50 times less then mobile phone)
  • Complete Network operator protection

*5G is now present on 700MHz and 2100MHz in many EU countries.


The StellaOffice repeater comes with different frequency options.

For rural locations we suggest 1,2 or 3 bands. For cities, we recommend 5 or 6 bands.

All services are covered: GSM, 3G, 4G and 5G

Your choice depends on your needs. If you only need to boost voice, we recommend the StellaOffice-G. However, if you want to boost data also, we suggest the 3 band or 5/6 band options.


The StellaOffice repeater kit contains 4 antennas. Each antenna provides 30 X 30 M2 of coverage in open space. Because it has 4 ports , you will have 4 separate areas with this coverage.

However, this is only in open space. In practice,  it  equates to about 10 sized rooms in a typical building layout. The coverage depends on the type of walls inside your building.

Concrete or metal insulated walls will reduce the coverage, whereas plaster board walls and  wide open internal spaces allow an increase in coverage.

See the example  coverage diagram above.

A:  This section of the building  we can get away with using one antenna as the signal will pass through the doors to the three offices.

B:  This section of the building  has a corridor separating the rooms. Here we will need at least three antennas to ensure coverage to all rooms and the corridor.

  2. 4 diagnostic lights: tells you if the repeater has:
    • power.
    • proximity control.
    • feedback.
    • communication with your phone.
  3. 6 light signal strength indicator: tells you the strength of your mobile signal outside.
  4. Connectors in: attach the 4 indoor antenna here.
  5. Connector out: attach the cable here and feed it up to the outdoor antenna.
