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"
