The Cel-Fi QUATRA solution consists of a donor antenna which is installed on the roof or outdoors where mobile signal is strongest, a network unit (NU) which amplifies and digitises the mobile signal from as little as 1 bar to up to 5 bars and a network of coverage units (CU’s) which are placed around the building to rebroadcast the boosted signal.

The system needs to detect a minimum 3G signal inside of the building to operate.
