Mika, just one note to your post, and it does not address the thrust of your comments. But on the subject of 100% retirement of AMPS, in Australia Telstra's stated objective is to shut down its analog network by year-end 2000 (it is in the process of being replaced by a CDMA IS-95 system, which is functional). While Optus and AAPT may maintain AMPS in areas of their wireless systems (and they may not, as their predominant networks are GSM), on the whole they are insignificant. Steve

Mika: On the use of "old" GSM spectrum after the "switch" has been made to some flavor of CDMA (your choice is WCDMA of course) in the new separate spectrum just auctioned in the UK for example, are you suggesting that one possible use for the residual (old) spectrum would be HDR? If so, wouldn't the inclusion of HDR in current GSM spectrum make sense with a gradual progression toward its "taking over" the spectrum in a half dozen or so years? Or to put this more directly, do you see any opportunity for HDR alongside GSM? Or is GPRS the only - and exclusive - option for use of current GSM spectrum for rapid data? Look forward to your thoughts on this. Perhaps I misunderstood your bringing HDR into this. Best. Chaz
