FYI - we have been able to get regular SMS and voice calls through (using Google Fi as our carrier). It was great to go from "absolute zero communication" to "we know you're currently OK"
- 3pt14159 6y agoSurely if there are telephone communications then someone can modem out? Or are they scanning for non-human communication over telephony?
- gpm 6y agoThe number of people with the hardware and know how to send data over a telephone line is probably very small.
- tanatocenose 6y agoSlightly ironic since this was once the only way. Brb investing in a modem.
- kube-system 6y agoNot with Google Fi, at least. Cellular networks are optimized for human voice and the compression will typically break the protocols originally designed to transfer data over landlines.
- tenebrisalietum 6y agoI wonder if cellular predictive encoding or whatever would break absolutely all of these modulation schemes. https://kb.iu.edu/d/aand https://kb.iu.edu/d/aand Bell 201A, for example. Loading modern webpages over 2400bps would be hell but IRC might still work. Or maybe time to break out the old UUCP.
- OnACoffeeBreak 6y agoFolks I've been in contact with cannot be reached by WhatsApp and email, but SMS seems to work. "We go from home to work and then straight home. Afraid to go out after dark so as not to get picked up by accident. Otherwise, everything is OK." is the message I got.
- Scoundreller 6y agoNot sure if I'd want to be using SMS without a one-time-pad right now. And even then, that could appear too suspicious.
- PopeDotNinja 6y agoTime to break out the 56K modems!
