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.
