Mobile Phone Signal Booster System

Metro Solutions are experts in designing and implementing full Mobile Phone Signal Booster Systems in Large office block buildings, small to medium commercial buildings, Large residential multi dwelling units and also large new house builds where insulation is causing issues with phone signal. Our GSM, 3G & 4G Phone Signal Booster Systems are also ideal for Ships, Boats, Yachts, Barges and Ferries.

The simple but effective Phone Signal Booster Systems locates the strongest local GSM, 3G & 4G mast and and draws the signal throughout the house over specialised cabling to repeaters discreetly located within the building and spreads the signal throughout the structure efficiently. This means the it’s as if you are using your mobile phone at the highest point of the building.

With such strong insulation in new buildings, particularly in new one off house builds, Mobile Phone Signal Booster Systems are an essential part of the build and best if planned for in the early stages so that allowance can be made for the specific cable structure to be in place before the walls are closed up.

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 Mobile Phone Booster System repeater.
  • The repeater boosts the signal to each of its 4 ports. 4 antennas can be installed within the building 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 and 4G)
  • 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


The Mobile Phone Booster System repeater comes with different frequency options.

You can choose a repeater kit that boosts GSM only, or a more expensive kit that boosts GSM, 3G and 4G.

Your choice depends on your needs. If you only need to boost voice, we recommend the StellaOfficeG Mobile Phone Signal Booster. However, if you want to boost data also, we suggest the 3 band or 5 band options.


The Mobile Phone Signal Booster 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.
