How the GSM 4G repeater works:
- The antenna on your roof receives mobile signal at 900Mhz and 1800Mhz.
- Both these frequency carry GSM voice signals, so this repeater is really the ultimate voice repeater.
- This signal is sent via coaxial cable to your StellaHome GSM+4G repeater in your house.
- Many networks now transmit 4G at 1800Mhz.*
- The repeater then amplifies the signal.
- The internal antenna sends this amplified signal around your house.
- Your mobile devices then communicate with this signal.
*use this tool to check that your operator uses 1800Mhz for 4G.
This booster kit includes
- 1 StellaHome900+1800 booster
- 1 internal and external antenna
- 1 power supply
- 12m coaxial cable(SD240)
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 your roof).
- Using the supplied 12m cable, run it down inside your house to the Stellahome repeater.
- Attach this cable to the repeater. Then attach the indoor panel antenna to the repeater.
- Plug in the power supply.
A closer look
- 4 mounting holes: if you want to secure your repeater to the wall.
- 4 diagnostic lights: tells you if the repeater has:
- proximity control.
- communication with your phone.
- 6 light signal strength indicator: tells you the strength of your mobile signal outside.
- Connector in: attach the indoor antenna here.
- Connector out: attach the 12m cable here and feed it up to the outdoor antenna.
- 12V Power in
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.
