But, that doesn't seem quite right, either. I seem to remember that the "overhead" involved with SMS is a couple of thousand bytes, what with the addressing and verification of receipt between the handset and basestation/server. That would make your time per message something more than 1 second (IF it is 2000 bytes additional), or 3 cents per message, maybe.
(Clearly, more research is needed before estimating costs and pricing possibilities, eh?)
<<160 characters is 1280 bits, correct? At G* 9.6K data rate, it would be
transmitted in eight seconds, and, at 1.5USD/minute, that would cost 0.20, or near the high end of
your range. >>
Eight seconds is .13 minutes, but the time required is 0.13 seconds so G* retailers could bill SMS for as little as 1/3 of a cent to send such a message
and still get their blessed 1.50$/minute. |
