Paul, <As far as something "better, cheaper, faster" than CDMA, not easy. OFDM seems like a nice idea, works great on phone lines, but that is a different problem, stable, narrow channel and a lot of processing power available.>
There was a new chip announced [Si GaAs combo]. <<Motorola unveils 'revolutionary' superfast microchip technology
news.independent.co.uk
"These new chips could run at more than 70Ghz, compared with the 2Ghz speed of the best current chips. It has not been possible, until now, to combine silicon with III-V materials – such as gallium arsenide and indium phosphide – as their crystalline structures did not match up and they could not be successfully bonded." > >
70GHz is presumably fast enough to handle some OFDM orthogonality. If not, then there seem to be continual improvements in processing power which will make OFDM easy enough [sometime].
My guess is that OFDM will be brought into the Q! realm and integrated into Q! ASICs and radioOne multimode, multiband gadgets.
What do you think? Any chance of OFDM going mobile by 2010?
