Statistical Range Analysis in RF Systems: the "Range Fallacy" Design How-To 5/5/2008 2 comments You read every paper you could get your hands on to do with propagation and path loss at the frequency you're using, and you carefully included all the known (and measured) losses, antenna gains, power outputs and sensitivities in a detailed link budget. A few days later the marketing dept arrives at your office: "You said the range would be 5 meters but we tried it at that distance and we could make it fail." What has gone wrong?
Power management in mobile devices--A view of energy conservation--Part IV Design How-To 5/5/2008 2 comments The gaps grow larger between what mobile devices can do and the amount of energy engineers can deliver. Chapter 2 from Power Management in Mobile Devices: Hierarchical View of Energy Conservation is an in-depth look at the power consumption, energy types, process and transistor technology, and packaging issues inherent in mobile device design. Part IV discusses low power process and transistor technology.
60GHz: Achieving the ultimate wireless dream Design How-To 5/5/2008 Post a comment Using sophisticated design and fabrication techniques, research labs are getting closer to realizing 60GHz chips in silicon. When that happens, consumer price points can be met and wireless design becomes a whole new ballgame. But first, engineers must overcome five major challenges.
