Cel-Fi Mobile Phone Repeaters Boost your Coverage & Data Speed

The Cel-Fi mobile repeater was designed to amplify and disburse a mobile signal within a building without causing any interference to the mobile network. The Cel-Fi is locked to the carrier and will only amplify a signal in that carriers set frequency range. The System compromises of two boxes, a Network Unit (NU) and a Coverage Unit (CU):

Network Unit
Communicates with the mobile base station, amplifies the signal and passes it to the Coverage Unit via a wireless link.

Coverage Unit
Is responsible for disbursing the mobile signal within the building to multiple mobile phone devices.


Cel-Fi Set-Up

A typical setup involves placing the Network unit in an area within the building that gets the best possible mobile signal from the cellular network. This would usually be an upstairs window or a window at one end of the building.

The mobile Coverage Unit is then placed within the main area of the building, or in an area that provides the best indoor mobile coverage.


The Cel-Fi repeater system is very unique in the way it maximizes the indoor mobile coverage. The NU and CU units can be up to approximately 30m apart, the further apart they viagra sans ordonnance are the better indoor coverage area will generally be. ARC can use a specialized enclosure to house the NU simulating the 30m separation and optimizing the indoor mobile coverage.


The network Unit has a mobile signal strength indicator, the greater the signal strength it gets from outside the better the indoor coverage is going to be. The NU has a port for an external antenna to assist if you have poor cellular signal.

The Coverage Unit has a signal strength indicator representing the output power.

If the CU is close to the NU it will display too close, as you move it further away the signal should increase up to 6 bars. At the same time the indoor coverage also increases.

Cel-Fi Enhanced Enclosures

The Cel-Fi Enhanced enclosures ensure no interference from Wireless access point and ensure maximum power out of the coverage units giving the best possible coverage into the apartments.

External antennas mounted up high on the roof of the building when connected to the Cel-Fi enhanced enclosures ensures the best possible signal input and resulting in the fastest data speeds.
