Fellow Nanogers: Reports have floated across my desk in the past week, which have suggested that iPhones owned by faculty, staff and students have been flooding university campus Wi-Fi networks in parts of the country. For example, see: *"Duke Wi-Fi Crippled by Apple iPhones" *at http://www.sci-tech-today.com/story.xhtml?story_id=10200AG9NMHU Since that story first aired, and by applying a patch that was subsequently provided by Cisco, Duke has now come to see the elimination of the problem, see: "*Duke Resolves iPhone, Wi-Fi Outage Problems"* at http://www.eweek.com/article2/0,1895,2161065,00.asp There are certain aspects of this story in which I have the most interest, and the following questions (if I may be permitted to list them) detail my concern - adequately. I wish to ask you: 1) is the iPhone an extra-ordinary device when comparing it with devices of a comparable nature, which also request ties to a Wi-Fi network, (there are many that use Wi-Fi enabled Smart-phones and PDAs on campuses -- so, why do 'they' not pose a similar problem) 2) is this problem a result of poor planning and services implementation at certain campuses, 3) is this story - a product of great exaggerations? 4) if there are technical issues indeed that permit iPhones in particular to DoS Wi-Fi nets, what can these storms be attributed to, and what can/should be done about it? If you are in a position to respond, I would like to hear from you, either publicly or privately. If there is enough group interest in the matter, I would be most happy to summarize. All the best, Robert. --
