 In the wireless infrastructure market, mobile operators are facing an explosion of
demand for mobile broadband.
 At the same time, they are under heavy pressure to restrain operating expenditures
(OPEX) and comply with new regulations on spectrum usage and power levels.
 These challenges — particularly the surge in data traffic — have profound implications
for the network.
 Mobile operators have to introduce new frequencies and implement re-banding, thus
increasing spectrum complexity.
 They also must implement new technologies, such as Long-Term Evolution (LTE), MultipleInput and Multiple-Output (MIMO), Remote Radio Head (RRH) and others.
 Furthermore, mobile operators need to increase cell densification and ensure ubiquitous
digital coverage, while implementing site sharing and improving power efficiency to
keep a rein on costs.

needed to support the coming surge in data traffic. Handling the surge in data traffic.
RFS Products and Solutions:
Wireless cell site solutions
RFS provides a complete portfolio of outdoor cellular site solutions covering the entire RF
chain, from base station antennas to diplexers and triplexers, from feeders and jumpers to
tower solutions. These solutions are suitable for 2G, 3G and LTE, whatever the frequency
band.
Radio Frequency Systems High quality, portable and fixed wireless transmission of speech or
music over FM radio frequency. Delivering superb intelligibility and crystal-clear amplified
sounds.
Radio frequency systems provide clear sound for assistive listening in small or large public
venues, and in tour guide applications.
 ContactRF assistive listening system ideal for when sound sources need to be wirelessly
transmitted across large areas, sending signals through walls, ceilings or other
obstacles regardless of building characteristics.
 Transmitters are connected to an audio source such as a microphone or PA system
and send signals to compatible RF receivers.
 Our system can utilise up to 42 channels simultaneously with a range of up to 100
metres in buildings.
 Receivers can be used with Inductive Neck Loops, allowing users to receive the sound
directly in their T Coil enabled hearing instrument.
