The space for high-speed wireless networking is getting mighty crowded. Techworld reports that a new company, Sibeam, has entered the fray, hinting at a 60GHz technology to compete with Wimax.
The radio data world is crowded with grizzled prospectors, all shouting: “There’s gold in them thar waves!”
Some are panning for nuggets in the frontier land of ultrawideband, while others are digging frenziedly in the badlands of 802.11n. One lone prospector is gibbering about an undiscovered lode called Xmax, while the rest all shake their heads.
Earlier this month, another 49er mosied into town, from another territory. Sibeam isn’t giving away too much about where it’s hopes for gold are located, but the rumours are that it’s to do with 60GHz signals.
60GHz isn’t undiscovered territory – quite the reverse. In 1895, some 30 years after Maxwell’s equations outlined the possibility of electromagnetic waves, the Indian physicist J C Bose, who studied under Lord Rayleigh at Cambridge, was channelling 60 GHz signals in his Calcutta laboratory and at the Royal Institution in London. He signalled with them, ringing a bell remotely, and his equipment – much of which still exists – included a wonderfully Victorian polariser constructed from a copy of Bradshaw’s railway timetable interleaved with tinfoil.
