Re: Cost is already paid? said by marigolds:There actually is a very significant bandwidth problem for SMS. That is why they have the 160 character limit. FEMA and DHS have been dealing with this technical limitation for the text alert system they have been working on. Could you elaborate on this please? |

kudos:1 | Unfortunately I don't have the technical background for it.
Basically though, the SMS provider is separate from the cellular provider and the SMS message is sent over a different protocol (that's why there is no way to geolocate an SMS message, but you can geolocate a cell phone call). The gateway network for SMS is a different network from that for PLMN. |

| SMS uses the SS7 protocol (for anyone who cares). As far as not being able to triangulate it, I'm not so sure about that, but I'll defer to the experts.
