Using Rebroadcast Sites for Coverage Enhancement
Creating a wide area RF “Distributed Antenna System”
RFI’s new DSP (Digital Signal Processor) repeaters are used in applications where existing
network coverage is unavailable. These units are also useful to as rapid deployment equipment or where the existing coverage boundary of the network requires extending.
These new channelised repeaters are ideal for network extension in-building, in-tunnel or coverage blackspots applications.
Their "RF-transparent" operation allows these repeaters to operate independent of network protocol as they support a seamless path for spectrum or technology migration being compatible with analogue and digital and proprietary modulations.
They may also be used to deploy cost-effective expansion to a network's coverage boundary or to provide multi-site coverage footprints from single-site infrastructure without the need for large scale site developments or dedicated backhaul.
The ability to change channel bandwidth, operating frequency (including cross-banding) and other performance parameters via local or remote programming allows this product to be deployed into a diverse range of analogue, digital, voice and data applications.
FEATURES:
- Analogue and Digital compatible (transparent)
- Channel selective with programmable per-channel profiles
- Multiple-band capability in a single chassis
- Programmable 1-35W RF outputper channel
- Can be configured as up to 16 individual full duplex transceivers
- TCPIP, USB and RS232 local control interface
- Easily expandable for additional channels &/or bands
- Up to 8 full duplex bi-directional
- Frequency translating and/or non-translating
- External Alarm I/O
- Temporary locations outside the normal network coverage area that may require coverage for specific activities such as natural disasters or other rapid deployments.
- Areas within the main coverage area that suffer from limited coverage due to localised topology, such as the base of steep mountains, rail/roads and narrow valleys.
- Mountaintop and remote sites that can provide full
coverage footprints from cost-effective site developments.
The space and power efficiency of such installations make them ideal for solar and generator powered locations. - Buildings which experience limited coverage from outdoor networks.
Rebroadcast repeaters are used for in-fill coverage
applications. Their “frequency translating” capability allows maximum power without regard to isolation. - Bored and cut-and-cover tunnels, underground car-parks and mines experience reduce coverage.
Rebroadcast repeaters provide frequency translation and higher per-channel output power assisting larger signal distribution networks (i.e. longer cable runs).
