GSM Repeaters

GSM Repeaters are amplifiers for mobile radio systems at various frequency bands (900, 1800, 2100 MHz, GSM and/or UMTS/3G). They are used at locations where the indoor reception of GSM/3G signals is impossible or insufficient. This is the case with many modern (or renovated) buildings which are perfectly shielded for better energy efficiency, but also against radio waves. Other scenarios are underground buildings like parking garages, cellars, storage rooms etc.

What is a GSM repeater?
A GSM repeater is a device that improves mobile phone coverage in buildings or other shielded areas. It amplifies the radio signal from cell towers, providing a better connection for mobile phones, tablets and other mobile devices.
How does a GSM repeater work?
A GSM repeater consists of three components: the outdoor antenna, the repeater and the indoor antenna. The outdoor antenna receives the radio signal from mobile phone masts and forwards it to the repeater. The amplifier amplifies the signal and passes it on to the indoor antenna, which radiates the signal into the interior. This can improve mobile phone coverage in shielded areas.
How do you install a GSM repeater?
The installation of a GSM repeater usually does not require any prior technical knowledge, as most devices come with simple instructions. The outdoor antenna should be mounted in a location with good reception, while the indoor antenna should be placed in a central location in the building. The amplifier should be installed between the two antennas. It is important to follow the manufacturer's instructions carefully to ensure optimal performance of the repeater.
