  • Small Cells:
    The cutting edge of in-building wireless

    Small cells connect to a service provider’s network through typical broadband, such as DSL or cable. They use this connection to then broadcast cellular service inside your building.

    Small cells don't require strong outdoor signal to boost your signal. You get a guaranteed coverage area, even if outdoor signal is weak.

  • Passive DAS:
    Lowest costs, fastest turn-around times 

    Passive Distributed Antenna Systems typically use passive components like coaxial cable, splitters, and diplexers to distribute signal. Unlike Active DAS, they use bi-directional amplifiers to rebroadcast signal from the macro cellular network using a donor signal on the roof. If the amplifier systems are classified as “consumer” boosters by the FCC they can be installed without any pre-approval or coordination with carriers.

    Passive DAS is generally much cheaper than Active DAS and because there is usually less need for carrier approval and coordination, deployment times can be as quick as a few weeks.

  • Active DAS:
    Coverage solutions for large venues

    A state of the art Active Distributed Antenna System can cover virtually any size of building and up to any capacity. Active DAS uses fiber optic cable to distribute signal between a centralized signal source and “remote nodes” placed around a building. The signal source is typically a “head-end” that combines signals from multiple carriers, which each need to provide their own signal source to the system, typically via their own fiber backhaul.

    According to FCC regulation, Active DAS must be approved by the cell phone carriers affected. Once approval is granted, carriers need to provide a signal source for the DAS.

How We Work

At RSRF, we pride ourselves on speed. Our Passive DAS solutions can be designed and implemented in just a couple of weeks.

Site Survey

We visit your site to measure existing signal inside and outside the building. We discuss installation practicalities and determine the coverage you require.


Our signal experts design your custom signal solution. The blueprint is tailored specifically to your building plan and signal requirements.


Our experienced professionals install your design. If you prefer, we can also assist in-house installation teams.


We test every component after installation to ensure we’ve delivered the signal solution you needed. Everybody can see the jump in bars - but our signal readings can put an exact decibel reading on the improvement delivered by the system.
