If, and only if, the goal is to ensure compatibility and constructive, free and open competition. This is why the operators have organized in ITU, earlier CCITT (europe), to avoid becoming the playground for manufacturers fights to win market share from each other. The US history is slightly different due to the monopolistic position of AT&T and "Bell Labs", but the "Bell standards" and CCITT standards were resolved somewhere between the 300 Bps FSK modem, Bell-103 and V21, leading up to V22,V32, V32bis and V90,etc (late 80s forward) At that time modems were the most mobile thing there was, demanding global standards (cmpr fax). Similar for the 64-56kbps problems, ISDN,etc,etc,etc. That is, the history of standards are littered with submarine patents and submarine upgrades, discriminating features, countered by submarine nets and mutually agreed testing and verification procedures and resulting in some isolated villages. There was even a guardtone (not -band, like for Q) added to one modem just to ensure functionality on one old Ericsson switch only used in Lapland, when the standard finally become commonly used. On the other hand one has all the reasons why Microsoft has a tough time in US courts, using their position to fend off competition. As well as the pain of having only IBM supplied paper for IBM printers hooked up with IBM cables to IBM mainframes (and then MS did what they did with the open AT standard). That is, what is the task of CDG and QCOM?? Ilmarinen. P.S. does it include ensuring the capability to ensure compatibility for a standard announced to be compatible?? (an open standard) P.P.S. Ensuring some kind of protection for their domestic economy is, obviously, a main target for all in terms of China, until they can compete on more equal terms in 10-15 years. However, few are as understanding in the case of part of US longing for a protected, isolated and guaranteed existence. (if you didn't get it, QCOM and CDG messed up really badly, not "testing" the "compatible standard" with existing equipment, the nightmare for any operator who think it can compete on a free, open market, but the last wet dream for anyone who cannot. One of the worst signals to send to any prospective operator)
