When a bird flies through the laser beam, the puter at the other end says, 'hey, send that bit again, a bird flew through the beam'. If it's foggy one day and even on full-power it's just gloomy, the signal goes via ADSL, GEO [when it's foggy it's often not too soupy overhead since fog is low-lying], Bluetooth, HDR or some other lower wavelength method. When bandwidth is limited, the Cat's Eyes show $8 $8 and people will stop sending Rats through the drain, so no interruption of service occurs. Having fibre to and around a city, with lasers for the last few hundred metres, mobile devices using HDR would be able to operate in tiny cellsites, fed by the fibre and lasers. There won't be a spectrum shortage [well, it'll always have a cost, but the cost will be really low and people will happily hog spectrum]. Civil engineering works and big town planning disputes, bribery and rents will go away as tiny Babe basestations get the bitstream from one of the surrounding fibre and laser supply points and distribute it to the HDR or cdma2000 devices in the area. Seems okay to me. I've asked at the 'Last Mile' thread too, as they are the aces on this stuff. airfiberinc.com I don't think this will be a niche product. I think it will dominate city and urban area transmission. Why bother with holes in the ground to lay fibre when you can make a cheap redundant network. If a tree grows up and blocks one path, another will be available and the blockage can be cleared. A bit like the Web doesn't stop working because a cable is dug up [unless there's no way around that cable]. Fibre will be for oceans and city to city, but lasers seem better for local stuff. Lasers and HDR. Why would anyone want to use slow, expensive VOFDM? It would be like going back to a 14kbps modem after ADSL. Mqurice
