Sending Data In Bursts of SMS Messages
An anonymous reader writes "Canadian carrier Rogers has been experiencing some extreme loads of late, as researchers at the University of Waterloo investigate the potential for sending data spread across bursts of hundreds of text messages. They sent around 80,000 messages in the course of a project testing a new protocol able to cram 32KB into 250 messages sent from a BlackBerry, reaching a rate of 20 bytes per second. The group thinks its protocol could be useful in rural areas of the developing world where text messaging is the only affordable, reliable link."
I think this is more a case of "Look mama, IP over SMS! With No hands!" than a solution for any real world problem.
WTF am I doing replying to an AC at 5 A.M on a Friday night?
I remember using acoustical modems back in 1974 and they weren't that new back then
I've actually considered seeing if I could get a v.32 in-software stack to communicate over the bluetooth headset/microphone protocol so I could do very basic data networking over a cell phone without a data plan. Like ssh.
I came to my senses, but I kinda still want to try it anyway.
My God, it's Full of Source!
OUTSIDE_IP=$(dig +short my.ip @outsideip.net)
The lossy compression used in digital cellular telephony has a smearing effect that screws with the rapid phase transitions used by quadrature amplitude modulation. You aren't going to get a lot of bits per second out of digital voice.
