The "whole carrier" referred to speaks not of a carrier as a wireless operator or their entire spectrum but 1.25Mhz of bandwidth which is a fraction of an operators total spectrum. 2. Yes. HDR does not work with existing handsets but new ASICS from Qualcomm will work with HDR, IS-95 and 1XRTT. 3. Another CDMA air interface. Kind of a mute point since the new chipsets will support the different modes.

"HDR requires operators to dedicate a whole carrier to data, rather than sharing data and voice over the same spectrum. " As I recall from the video of the HDR presentation, with the present ASIC, HDR must be on a dedicated channel (1.25MHz wide) and can not be mixed with voice. This was covered by Don Schrock, head of the ASIC group. I was glad to find this link qualcomm.com which gives a MSM roadmap. Confirms my recollection, need a MSM4500, due in Q2 2001, to mix voice and HDR on one channel. These are the view graphs from the HDR presentation and are well worth the time (loads slow, Acrobat file).
