Sorry, but I fail to pick up what you are trying to say.

About Ericsson - yes, I think they have dropped all GSM modules. Royalties? Yes, if you have the patents, you should of course want to reap the benefit. Why else spend the research time inventing new technology? Just so your competitors can use it for free without the initial research cost? That way, the company who did the research may get a product out the door a bit earlier, but would not be able to sell it at a competitive price because of the very much higher development costs.

Nothing wrong with the Wavecom hardware, but the bad thing about them has for many years been the firmware. They have released a large number of quite bad firmware. Tech support has vividly explained that problem x is not in their module but in an embedded application. Then suddenly, the problem goes away in the next release, but something else breaks. Same thing - not firmware but the application. Suddenly works again in the next release... And the firmware updates have often broken the compatibility with embedded applications run in the modules, requiring updates. Funniest of all is when firmware version x can only use application version x, and firmware version y can only use application version y, and the factory gets modules with both firmware x and y and if they misses checking the version or upgrading the firmware in a module, they must then unlock the module... In the end, the produced units can work quite well with the Wavecom modules, but the maintainance costs have a tendancy to be way too high.
