How the GSM Office signal booster works:

  • The outdoor antenna installed on the roof, receives the operators GSM signal.
  • This signal is sent via coaxial cable to the StellaOffice GSM booster installed inside the building.
  • Here the signal is amplified equally to each of the 4 ports of the repeater.
  • Each of the 4 ports leads to 4 antennas placed within the building.
  • Each of these antennas can provide coverage in about 3-4 rooms. That’s up to 15 rooms in total, depending on the type of rooms.

This booster kit includes

  1. 1 StellaOffice900 Amplifier
  2. 4 indoor antennas
  3. 1 External high gain antenna
  4. Individual lengths of coaxial cable(3 x 15m) to connect the antennas.
  5. 1 power supply

Quick install guide

  1. We recommend doing a "loose" install first, so that you can test where best to place your cables and antennas.
  2. Install the outdoor panel antenna in a location where there is good mobile signal. (usually this is the roof).
  3. Attach the 15m cable to this antenna and run it down inside the building to the Stellaoffice repeater.
  4. Attach this cable to the repeater. Then attach 1-4 cables to each of the  ports the the repeater.
  5. Cable from these ports to 4 locations that require coverage.
  6. Plug in the power supply.

The frequencies explained:


900Mhz is used for the GSM network. GSM is a robust standard used by your phone and the operator’s base station to transmit voice signals. It has been about for a long time which is a testament to how successful it is. All phones, including the older “non-smart” phones can use this standard. 900Mhz is a relatively low frequency that is excellent at propagating through the countryside. It is most likely that this frequency is available outside your house (Can you make calls outside your house?). It also uses much less power then 3G or 4G. ie, your phone battery lasts longer!
