Cel-Fi is a device, similar to a cellular repeater
, designed to eliminate in-building dead zones and improve indoor mobile phone
reception.
Created by Nextivity, Inc., the Cel-Fi systems are designed with smart antenna technology to seek out the best available signal to maximize signal gain to phone user. The Cel-Fi consists of two wireless devices, a Window Unit and Coverage Unit that work jointly to increase 3G
and 4G
mobile broadband
connectivity throughout the building. The window unit receives the signal and relays it to the receiver, which converts it and amplifies it.
Trialed for a period of time in both the US and UK by T-Mobile
. Approved in UK by T-Mobile
and Orange in 2011. Cel-Fi systems are comparable to mobile phone repeaters and femtocell
technology.
