The Stella Office Tri band booster ensures that all operators are amplified for Voice(GSM) and 3G data.
If your operator transmits 4G at 1800Mhz, you get this too.
Used for large buildings where the indoor coverage is weak or non existent. It amplifies 900Mhz, 1800Mhz(4G) and 2100Mhz ( 3G).
The Tri band booster is very useful for offices where many people will be with many different operators and will be using voice, email and 3G internet. All options are covered so you don’t need to think about which frequency to use.
This booster has 4 indoor antennas. Each antenna will amplify 1000Mt2 (~3 rooms), so in total, this kit provides ~15 rooms coverage.
This booster kit includes
1 StellaOffice 900/1800/2100 Amplifier
4 indoor antennas
1 External high gain antenna
Individual lengths of coaxial cable(3 x 15m) to connect the antennas.
1 power supply
Quick install guide
We recommend doing a "loose" install first, so that you can test where best to place your cables and antennas.
Install the outdoor panel antenna in a location where there is good mobile signal. (usually this is the roof).
Attach the 15m cable to this antenna and run it down inside the building to the Stellaoffice repeater.
Attach this cable to the repeater. Then attach 1-4 cables to each of the ports the the repeater.
Cable from these ports to 4 locations that require coverage.
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!
1800Mhz is a mid range frequency. Most operators transmit GSM and EDGE data at 1800Mhz in cities. EDGE data is low bandwidth and is only suitable for emails. Many mobile operators use 1800Mhz for 4G also.
2100Mhz is used by all mobile operators for the 3G network. This is available in all cities and offers very fast data speeds. It is also available in many parts of the countryside but you should always check outside your property to see if you can receive this frequency on your phone. Generally, if you can browse the internet on your phone outside your property, it is likely you are on 2100Mhz, 3G.
