Cablefree connects to Satellite Uplinks

The Scenario:

Satellite uplinks and downlinks are frequently used for telecommunications and broadcast television applications where temporary connection has to be made – such as television news reporting and coverage of live sporting events.

In such applications the uplink may be a suitably equipped vehicle with line-of-sight coverage of the satellite orbit, or a permanently installed antenna which cannot be moved. The terrestrial problem is then connecting the source to the uplink terminal, and the downlink terminal to the recipient – this is traditionally performed with leased-line, fibre-optic, copper cable or microwave links – all of which have associated penalties.

Cablefree offers a new, high-performance alternative for the terrestrial links:

Cablefree offers 622Mbps, compared with Microwave links typically 34Mbps
Copper 270Mbps SDI connections limited to 300m, Cablefree offers 2,000m
No site or frequency licenses required
No leased-line rental or connection charges
Long runs of fragile fibre-optic and expensive Tri-axial video cable are not needed
Deployment time is reduced compared to running long fibre or copper cables
Wide range of data interfaces allows ‘plug-in-and-go’ for any format
No risk of interference, signal reflections or airport radar systems
No ignition hazard in flammable environments
Mains or +12V battery power options
Low manpower costs and rapid response capability
Suited for permanent or temporary use, leasing options available
Cost-effective solution

CableFree links to Satellite Television feeds

A classic television newsgathering operation requires live or near-real-time relay of events from around the world to a news desk often the opposite side of the planet. Whether from a disaster area, terrorist siege or war zone, time is of the essence. High-quality television signals need to be relayed from a camera to the satellite up-link, often when high-bandwidth network connections are unavailable locally or will take too long to organise.

Cablefree offers an ideal solution which carries high-quality analogue or uncompressed digital pictures with a system that can be rapidly deployed on tripods and powered from 12-volt batteries. With no need for frequency allocation or licensing, Cablefree can be deployed anywhere in the world and even used in war zones with no risk of interference with military communication systems.
