Reliable Mobile Signal – Anywhere You Need It

If you’re working in a large office, a remote industrial site, a busy city or rural location a poor mobile signal can disrupt your work, communications, prevent you from making that call and just getting on with the things that matter.

Avoira Radio offers CEL-FI mobile signal booster solutions to help you stay connected no matter where you are. CEL-FI mobile signal booster delivers stronger voice clarity and faster data speeds indoors, where mobile signal is often weakest.

What is CEL-FI?

CEL-FI is an advanced mobile signal boosting solution that enhances your existing mobile network coverage. It uses award-winning technology to amplify and rebroadcast mobile signal inside buildings, providing reliable voice and data where it’s needed most.

CEL-FI is the only signal booster system approved for use in nearly 100 countries and by almost 200 mobile network operators. It is fully network-safe and does not interfere with other signals.

How it works

Mobile phones connect to mobile network towers through signal. That signal can be weakened by obstacles like thick walls, metal construction, remote terrain, trees, or even poor weather conditions. This results in dropped calls, poor voice quality, no signal and slow data.

CEL-FI fixes this by using three core components:

A donor antenna placed in an area where signal is strongest
A booster unit that amplifies the signal
A server antenna that distributes the enhanced signal throughout the interior space

This system captures the existing signal, strengthens it, and rebroadcasts it indoors allowing for clear calls and faster data connections inside your building. For larger buildings or complex layouts, multiple antennas or systems can be installed to increase the coverage area.
