Link Research Tests Wireless Camera ENG in London

"Cellular Diversity" tests demo live TV news from city buildings without OB trucks (April 15, 2005)

Tests by Link Research show that wireless cameras can operate in city centres, using a fixed receive point instead of an SNG vehicle with a full technical crew. This concept could revolutionise news-gathering in built-up areas.

Link Research calls its new technique "cellular diversity" because the cameramen can move between receive stations just as people with mobile phones move between the base stations that carry cellular signals.

Link Research carried out its tests in Central London, using the BT Telecom Tower as a receive point. Test results showed that at a standard LinkXP 100 mW output, a wireless camera system would operate reliably at least 1km from BT Tower.

With an additional power unit, it was possible to cover all of Central London's key news-gathering areas: the Bank of England, Buckingham Palace, Whitehall, Leicester Square and the Oxford Street area.

The tests demonstrated that it was no problem to get reliable coverage for the financial district, the City of London. This is an area where slow traffic and parking restrictions make access difficult for live broadcasts and the tall buildings often block satellite signals.

The wireless camera equipment used in the tests can easily be carried by a journalist or a cameraman on a motorbike or even on public transport or taxis. All that is required is to clip on a battery, plug in the aerial and switch on.

Link's "Cellular Diversity" was used for its first major live UK event on Easter Sunday: for ITV's Oxford and Cambridge Boat Race. The race, filmed on the Thames between Putney and Barnes requires the cameras to cover a 4-mile stretch of river. ITV chose to use wireless equipment attached to the boats and along the riverbanks.

"Fixed receive networks like this could save our news broadcasters a great deal of time and money and get the cameras into places where vehicles can't go," says Len Mann of Link Research. "There is no need to rig and re-rig receive stations for each event. The broadcasters that do this will reap the real benefits of wireless camera technology."
