Mr. Unger has taken a topic not often discussed and almost never written about and has done an absolutely wonderful job with it! Even if you are not interested in becoming a WISP or needing that technology, you should have this book as a reference. The material that he covers in regards to the 802.11x standard is literally worth its weight in gold. His information on antennas, different LOS types and trooubleshooting could be a book itself. And for any of you looking to obtain any of the various WLAN certifications (Planet3, GlobalNet, Cisco, etc.), this book is a "keeper". Keep up the good work Mr. Unger!
