Indoor antenna system

Radio Frequency Systems has developed ClearFill - a suite of end-to-end wireless indoor solutions that helps coverage in buildings and tunnels.

The suite comprises a mix of passive and active RF technologies, providing a scaleable and flexible approach and consisting of four main elements in the range.

ClearFill Air is for basic indoor coverage for small buildings using an off-air repeater and single antenna assembly; ClearFill Line is a purely passive distribution solution founded on a radiating cable or distributed antenna network, suitable for small buildings and short tunnels; ClearFill Boost - inline bidirectional amplifiers boost the signal along a length of radiating cable or feeder cable to achieve coverage in longer tunnels and larger buildings; ClearFill Space is a hybrid solution for midsize to large indoor complexes, or the longest tunnels, comprising fibre-fed repeaters with RF converters to drive the signal through the otherwise passive RF distribution network of radiating cable and/or distributed antennas.
