You're apple and Beta corrolaries flounder here. Sony didn't have any basis to mount an IPR battle with JVC over VHS. Apple corollaries fail on many levels. They have defended IPR against Microsoft with varying levels of success. Apple refused to license their OS to other hardware manufacturers until it was too late. Qualcomm has licensed their IPR to more than 60 companies to date. Microsoft was able to eventually bypass Apple's software patents and take their market share away from them. Microsoft found the way. Companies around the world have been trying for a decade to do the same thing to Qualcomm. Have they succeeded? Apparently, ETSI is the only one issuing a statement I can believe. We know about the CDMA patent search word counts. But, as a self-proclaimed Patent dude, do you understand the drawbacks of specifiying CDMA as the only air-interface a patent applies to? You claimed "W-CDMA allows companies which system TDMA/GSM equipment to upgrade their existing equipment to W-CDMA. Next, with many manufacturers of W-CDMA equipment drives the prices down of that infrastructure. That is simple supply and demand." Upgrading GSM to WCDMA involves replacing the spectrum license, base station transceiver, antennas, base station controllers, along with coverage changes forcing an increase in base station density. While coverage is being expanded, TDMA compatibility has to be added to WCDMA handsets to roam on existing GSM systems. Cadillacs and Jaguar's have supply and demand but are still very expensive. Is there a corollary here? Will GSM providers struggling in the US be in a position to invest in the upgrade? Or, am I asking the working-class providers to buy me a Jaguar so my European stock doesn't collapse? According to the CDMA2000 spec on the CDG website, IS95B will continue to be used for voice traffic. Before CDMA2000 and CDMAOne/HDR are deployed, IS95B offers 110Kbps data with little more than a new handset and base station software upgrade. Qualcomm has the ASIC for 55Kbps and it is an economical replacement for their older MSM chips. Bringing current digital standards to the masses required consumers to replace handsets plus better price plans (in many cases, free roaming and no service contracts.) Big reasons to switch from AMPS included call security, eliminating fraud, lower costs, and improvements in call reliability. How is WCDMA expected to churn existing customers if current digital standards (and their handsets) meet our needs? What if WCDMA is not as reliable as GSM/TDMA or CDMAOne? What if the 110kbps feature of IS95B is useable for 90% of wireless consumers and involves zero hardware changes on existing infastructure? Expecting us to jump onto the 3G bandwagon for wireless multimedia? Whatever you do, don't discount the latest PCS survey found that fewer than 10% of wireless users have an interest in HDR service. Knowing all this, your enthusiasm for WCDMA appears to be horribly misplaced.
