Frequency
The StellaOffice 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 StellaOffice-G. However, if you want to boost data also, we suggest the 3 band or 5 band options.
Coverage
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.
