Indoor mobile phone signal boosters for the O2 network

and all O2 hosted Networks

The Cel-Fi PRO wireless signal booster eliminates dropped calls by creating a bubble of 3G and 4G / LTE signal coverage indoors, amplifying the signal by up to four times (100dB gain) in a 20 metres radius area (13,000 sq.ft.). Ideal for offices and small-to-medium businesses, this plug-‘n’-play technology is the fast and effective solution for improved signal.
