What is a Smart Repeater?

The Cel-Fi Mobile Smart Repeater is a convenient solution to poor indoor phone coverage. Installing this device in your home can improve the reliability of phone calls, text messages, and increase 3G mobile broadband signal. For areas with poor outdoor coverage this model has an external antenna connector to allow the connection of an external antenna. To achieve this the smart antenna system comprises of two units:

The Window Unit

This is the primary receiver and transmitter - it simply receives and transmits at the power of a normal mobile phone, no amplification whatsoever. Yes, this means those of us in low signal areas will still need to connect it to an external antenna via the small gold SMA Female connector underneath. It then communicates this signal wirelessly to the second 'Coverage' unit.

The Coverage Unit

When placed deep within the house or office where signal is weakest, this unit will receive the mobile phone signal (over the 5GHz band) from the Window Unit and rebroadcast it at full strength throughout the house. This special two-hop system allows the mobile phones to pick up and transmit the signal at full strength, without the system actually broadcasting any louder to the outside world - ie. without jamming your neighbours or overloading the cell tower.

Why do I need to connect an external antenna?

Smart Repeaters transmit and receive at the same strength as a normal mobile phone. As the old adage goes 'garbage in, garbage out' - if the repeater is receiving a poor quality signal all it will do is transmit that poor quality signal louder throughout the building. Connecting an external aerial is a quick way to dramatically improve signal levels, allowing the repeater to boost call quality, mobile broadband speed, and reduce 3G drop-outs.
