Thanks for the insightful comments. Dan, I agree. Some of my customers have done their homework and quantified the relationship between proper testing and profits. Obviously, their conclusions are proprietary and I can’t share them, but the numbers would astound you. Consider all the areas impacted by a bug in a released device: customer support, subscriber revenue (renewals and new customers), and even the operational network-side costs of supporting marginally-performing devices. Multiply that number by hundreds of thousands and you realize that you are talking about significant amounts of money. Iqbal, you raise an interesting point, but I’m afraid I’m not very closely involved with LTE/WiFi mobility. It does raise some interesting questions, though… for instance, will an LTE operators be willing to hand a viable call over to a home network, with little insight or control of its success? Should they, knowing that failures will cost them in customer support resources? Thanks for the idea.

I have never found short cuts in testing to make economic sense. Correcting problems in the field is terribly expensive! The wireless industry should never be without a serious trial deployment, for each technology.

In addition to UMTS, CDMA and LTE, users will also expect seemless operation with WiFi hot spots. For example, when a user is within the range of a WiFi hot spot, LTE is not needed. Therefore, a critical success factor for LTE devices will be how well they manage the transition from one wireless interface to another and it does not have to be annoying to the user. There are new and unprecedented challenges to test mobile devices that can interoperate over multiple wireless technologies. Regards. Visit us at uspurtek.com

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
