I've begun adding my personal notes pages on different technologies. I'm going to start with one on Wireless Technologies. See the new section below the reading list on the left. Please read the disclaimer regarding the accuracy of the notes before depending upon them, and realize that these are only supposed to be cursory looks at the technology involved, and may not be as deep a knowledge as you require. I may include individual research links in each guide, or I might not - depends on how motivated I feel.
