Guide to Smart Repeaters - International Carriers
Interference-free mobile coverage
Cel-Fi is a smart signal booster. It relies on intelligent, self-organising algorithms so you can benefit from the largest area of coverage without compromising or interfering with your mobile operator’s networks, or impeding other subscribers’ signals.
Plug and play
Cel-Fi does not require any new equipment, configuring, or changes to existing network infrastructure or mobile devices.
It's a plug and play device, which means there's no need for professional installation - no drilling and no cables.
Country & operator specific solutions
Cel-Fi Smart Repeater units are controlled and operated as an extension of an operator’s network. This is what allows Cel-Fi (by regulatory authority), to boost signals about 1000x more than other solutions, and therefore cover very large areas even if the original network signal is weak.
Licensed and authorised
Broad-spectrum repeaters can cause interference and damage to networks, so operators have adopted a strict policy against the use of legacy signal boosters on their own networks. However, Cel-Fi (the only smart signal booster of its kind), is authorised for use by each carrier, and allowed to transmit on their licensed spectrum, without impacting other users.
