Использование одновременной передачи радиоволн в одном диапазоне, но с разным орбитальным угловым моментом позволило группе американских учёных добиться беспроводной отправки данных на рекордных 2,5 Тбит/с.

Recent work suggests that the trick could vastly boost the data-carrying capacity in wi-fi and optical fibres.

Alan Willner and his team at the University of Southern California, along with colleagues at Nasa's Jet Propulsion Laboratory and Tel Aviv University, have now demonstrated one way to do that.

Initial experiments were only carried out over a distance of about a metre, and Prof Willner said that challenges remained for adapting the approach to fibres or for longer-distance transfer.

«For situations that require high capacity… over relatively short distances of less than 1km, this approach could be appealing. Of course, there are also opportunities for long-distance satellite-to-satellite communications in space, where turbulence is not an issue.»
