<I can't begin to estimate or measure how much the overlapping CDMA channels will improve Internet speeds or voice capacity as these 8 different 3G channels overlap in existing markets. In the product description for the CSM 5200, Qualcomm begins to discuss the cascading effect of several base stations. Doesn't the presence of many CDMA1X or CDMA1XEV DO channels in a 10 MHZ range of current spectrum give CDMA providers greater capacity and speed than providers using 5 MHZ of paired spectrum for WCDMA?> qualcomm.com Eric pointed me to the Goldman Sachs presentation. This slide shows data throughput comparisons in per sector in 5 & 10 MHZ. The following 2 slides show the cost per MB and the voice capacity benefits of 1XEV DO vs. WCDMA. The slide is different than comparison in Qualcomm's White Paper - The Economics of Mobile Wireless Data. That study compares data throughput for a 1.25 MHZ carrier bandwidth for CDMA2000 1XEV vs. a 3.84 MHz carrier bandwidth for WCDMA.
