Assuming engineer is remote access constrained (<g>), gdichaz: HDR can be used in tandem with IS95 or with CDMA 2000 or, I believe, also with W-CDMA. It is a separate data only channel that carriers can use if they choose to make available high data rate services to their customers, along side a complementary CDMA voice RF or (less likely because of the politics and Holy War residue) alongside a GSM voice RF--but that would be more complicated and certainly more costly, as you would duplicate infrastructure if you weren't going with the CDMA overlay (engineer, correct me if I'm wrong here). HDR involves an easy chip/software upgrade route from IS95 and CDMA 2000 BS and mobile ASICs (MSMs, for Q). Thus, Sprint, for example, could choose to employ one 1.25 MHz channel for HDR and continue along whatever upgrade path it chooses for combined voice and data channels in its preferred IS95/IS95C/CDMA 2000 migration. So could other carriers. Thus, HDR should be viewed as complementary and/or alternate, depending how the carrier elects to deploy a higher data/voice rate strategy.
