I spent some time -- years, actually -- working with the IETF on various Internet standards, particularly IEEE 802.x, the standard for wireless communications. I reviewed and read many resources and sources, and while this book came along a few years after I had gotten involved, it was still one I read with interest, almost as an after report of some of the stuff I worked with various experts on. Not the best, in my opinion, but not bad either. Naturally, obsolete by now. Still, for basic historic purposes, recommended.
