iPhone and Network Disruptions ...

["Prof. Robert Mathews (OSIA)" <mathews () hawaii edu>]

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.
