Hi Joe,

I don't get the NY Times, but I can respond as I am designing similar products at present. GSM originally operated at 900 MHz, everywhere but in N/S America. With PCS it uses 1800 MHz in Europe and 1900 MHz here. The chips to handle these multiple frequencies are available, and it is only a matter of time before the handsets get designed and manufactured. Now all this is at the RF end, where companies like Triquint excel, as well as the full line cos. as Mot., Harris, Phillips, and now TI with their new RF offerings. The BASEBAND portion is basically the same, so this only affects VLSI in that the more GSM handsets produced the better. Actually the ultimate phones are triple mode(AMPS/TDMA/GSM)/triple frequency and that does impact the processor, but the market their is limited. FYI the newest CDMA phones are dual mode(AMPS/CDMA)/dual band(800 MHz/1900 MHz). Jim
