Apparently this "new" #communication #method can be used to #transmit 1.8 #petabits per #second https://www.dtu.dk/english/news/all-news.. I guess the neat trick here is #splitting the #laser #light and creating an #efficient #encoder and #decoder #chip . Interestingly it doesn't mention #distance - and it is unclear to me if they could #transmit in reality using the full #spectrum via #fibre .
Interesting use of a #can #bus for 3D #printer #sensor / #actuator #communication https://hackaday.com/2021/11/03/simplify.. Still, it's quite over the top. There really isn't *that* much noise on the communication lines!
Interesting #audio #encoding concept getting barely #audible #voice down to 450 bits/second: https://www.rowetel.com/?p=6212 The proposal is that this could potentially be used for #lora #realtime #communication over very #lowbandwidth channels.
Great story from #countdankula about how the #uk went to #war with #iceland over #fish https://www.youtube.com/watch?v=R3wx-Nam.. This whole ordeal was before my time, but still a very interesting story. Hopefully the #british #navy learned from their #communication mistakes, to which the #military have had many. Reminds me of a #radio #frequency mishap that fucked up #operationmarketgarden in #holland ( #battleofarnhem )...
Awesome use of #lora to perform #mesh #voice #communication https://hackaday.com/2021/06/06/qmesh-lo.. Seems like the trick to reducing network traffic here was a predictive mesh routing protocol. I think that voice compression is another potential trick to reduce bandwidth...
