***Cisco, Wi-Lan, CDMA WLL*** Cisco and Wi-Lan are getting excited about their OFDM be it V or W or just VW [as in vapourwear like the good old W-CDMA invented in a school of hagfish back in 1889].

BUT! There is definitely going to be mobile WWeb all over the world in 5 years and a LOT sooner than that in Japan [7 January in 64 kbps cdmaOne IS-95B networks] and Korea with Freetel [with Microsoft and Qualcomm backing] doing HDR late 2001 and certainly during 2002 and maybe in a lot more places too. Then cdma2000 and the VW40 clone [W-CDMA] will come out not long after that [though NTT with wishful thinking is still talking about VW40 in 2001 hahahahaha - good luck, they'll need it].

So, if there is CDMA all over the place for mobile services and it will mainly be used for voice during the day, then it will have a lot of space at night, which is one reason there is a lot of discounting for off-peak use. That evening space could be used for WLL WWeb data, meaning Web surfing in the home. The capital will be already installed.

That will make it a lot cheaper than building out OFDM networks which are only good for fixed applications.

Lasers and other directed spectrum is likely the best solution for fixed WWeb in houses. Huge bandwidth and low costs and no spectrum shortage. Too bad about a spot of rain. With those house to house links, maybe rain won't be much impedance anyway.

OFDM seems interesting, but uneconomic since everyone will want mobile anyway.

WWeb is going to be huge and it is going to happen soon. The present dithering over whether there is a market for data is nonsense based on useless data services over cellphones during the 1990s when promises were great, costs high and delivery rotten. Of course not many wanted data under those circumstances.

But now there is the Web. We all want it. We all want voice. We all want speed. Seriously fast speed. The idea that people don't need the speed of 3G or faster is silly too. All that HDR can supply and more will be gobbled up. Speed, speed, speed. Cheap, cheap, cheap.

The service providers who dither over data are going to lose lots of customers in a short time. NTT will be one of the first to take a pasting. Europe will be left behind as they sit proudly with their anachronistic GSM universal monopolistic standard and no CDMA. A spot of GPRS maybe. That won't be much use. EDGE will never see the light of day.

The USA will roar ahead. As analog phones are ditched by the 10s of millions in the USA, CDMA and data will take off. 2000 is going to be a LOT of fun in CDMA. Especially as carriers ditch the 'called party pays' weird idea which saw USA subscribers keeping their mobile numbers private! Or not even buy a phone. Crazy!
