Subject: Re: Questioning the wisdom of permitting texting to E911 services Message-ID: <firstname.lastname@example.org> Thad Floryan <email@example.com> wrote: > This still leaves open the issue about using SMS to contact > E911 services with this paragraph > > http://en.wikipedia.org/wiki/SMS#Unreliability > > disparaging the texting-to-E911 efforts as reported here: > > http://bigstory.ap.org/article/4-major-phone-carriers-providing-text-911 > Perhaps this is a special case of very narrow interest, but I am in favor of the proposal for the following reason: I spend some time in an area with marginal cellphone coverage. Despite the use of a yagi and a low-band cellphone service I can only obtain a voice connection roughly 40% of the time, depending on local meteorological conditions. Under these same conditions an SMS message will always punch through within 30-60 seconds. SMS-911 would extend the coverage area of the existing cellphone network for emergency communications for any customer. As to the unreliabliity issue, I wish someone more knowledgable would respond. My expectation is that the SMS data connection is quite reliable within a given carrier's network. The public gateways between the various carriers may have congestion issues leading to dropped SMS messages if nobody is tending to the traffic engineering. Is this correct? -- We is confronted with insurmountable opportunities. -- Walt Kelly, "Pogo"
