Frank Thornton runs his own technology consulting firm, Blackthorn Systems, which specializes in wireless networks. His specialties include wireless network architecture, design, and implementation, as well as network troubleshooting and optimization. An interest in amateur radio helped him bridge the gap between computers and wireless networks. Having learned at a young age which end of the soldering iron was hot, he has even been known to repair hardware on occasion. In addition to his computer and wireless interests, Frank was a law enforcement officer for many years. As a detective and forensics expert he has investigated approximately one hundred homicides and thousands of other crime scenes. Combining both professional interests, he was a member of the workgroup that established ANSI Standard "ANSI/NIST-CSL 1-1993 Data Format for the Interchange of Fingerprint Information." He co-authored WarDriving: Drive, Detect, and Defend: A Guide to Wireless Security (Syngress Publishing, ISBN: 1-93183-60-3), as well as contributed to IT Ethics Handbook: Right and Wrong for IT Professionals (Syngress, ISBN: 1-931836-14-0) and Game Console Hacking: Xbox, PlayStation, Nintendo, Atari, & Gamepark 32 (ISBN: 1-931836-31-0). He resides in Vermont with his wife.
