Cell phone networks are often the first telecom technology to get overloaded (or in some cases just fail completely) in an emergency. Start sending out text messages to everyone, and you're likely to trigger thousands or millions of immediate call attempts by users trying to reach family members, etc. Boom -- saturation, and the really important emergency calls don't get through. Most people don't realize how limited cell phone capacity really is, relatively. Of course, the cell carriers don't exactly promote their limitations. --Lauren-- Lauren Weinstein lauren () vortex com or lauren () pfir org Tel: +1 (818) 225-2800 http://www.pfir.org/lauren Co-Founder, PFIR - People For Internet Responsibility - http://www.pfir.org Co-Founder, IOIC - International Open Internet Coalition - http://www.ioic.net Moderator, PRIVACY Forum - http://www.vortex.com Member, ACM Committee on Computers and Public Policy Lauren's Blog: http://lauren.vortex.com DayThink: http://daythink.vortex.com ------------------------------------- You are subscribed as traynor () cse psu edu To manage your subscription, go to http://v2.listbox.com/member/?listname=ipArchives at: http://www.interesting-people.org/archives/interesting- people/
