HDR sounds great, but is the bandwidth required for widespread use of HDR going to available (as qdog asked)? Will operators have to give up some voice capacity to implement HDR? How will that be possible given the growth requirements of voice alone? You should listen the the HRD demo. Irwin explained how this works. Let's see if I can remember correctly. IS-95 works in 1.25Mhz channels. So if a carrier has 5Mhz of spectrum and one 1.25Mhz voice currently, then by putting a new card in place of the old one, upgrading the software and selling handsets to new subscribers that are 1XRTT compatible the maximum voice capacity is doubled. The old (current) handsets work with 1XRTT but I think they do not take advantage of the doubling of capacity so actual voice cap. gains may be proportional to the proportion of 1XRTT compatible handsets. This could really benefit Q since carriers with voice capacity constraints may, at some point, offer strong incentives for old subscribers to upgrade to a new model handset. Back to the example. So the carrier would still have two 1.25Mhz channels for data, each one serviced by a T-1 line. My impression is there would be plenty of spectrum for immediate needs. I would appreciate someone who has experience or knowledge about the carriers current state of affairs to either support or refute the Nortel exec. claim that "lots of operators have their spectrums completely full." Personally, I doubt if he is referring to CDMA networks. With all forms of mobile CDMA, network capacity for voice and data can be increased within the same amount of spectrum by adding additional cell sites. This is not possible with the archaic technologies of the GSM family. Bux
