@stardot @delta potentially.

  • Tho I do expect some classic mail push/fetch and local mailservers doing caching...

Just like in #McMurdo and #AmundsenScott, cuz #SATCOM via #TRDS (McMurdo) and #Iridium (#SouthPole) is expensive af...

  • So expensive in fact that people literally have to "get in line, take a number!" and depending the amount if data and priority of their comms they may be faster just grabbing an SSD, fill it up and send it back with the next plane...

@kallemp I didn't bother with #LoRa due to it being patented and #Meshtastic for tending to pollute #ISM spectrum.

Also #CEPT does have data channels on #CB radio that are allowed to be used.

  • Given the low duty cycle, I'd say it's worth using said #LicensingFree channels. Espechally since the only "regulated" part are transmitters and those are just transparent cheap boxes, so #AFSK will be fine.

OFC one could use this across any spectrum or means, ranging from WSJT - moonbouncing at extreme narrowband and high frequences to #UHFSATCOM radio piracy. Obviously I disrecommend the latter for legal reasons!

  • OFC one could also use it across i.e. #Iridium and other #SATCOM and regular #VHF & #UHF radios or even just print messages as QR-Codes...

@amayer @mastodonmigration @GottaLaff NOT TRUE!

The entire CnC systems for #UAV|s by the US DoD use X-Band for video feeds and #Iridium for remote control.

  • In combat theaters, drones get either controlled by operators on the ground in visual range or get their targets directed by them i.e. via IR Laser Designators (so a Hellfire Rocket can home in!)

Basically no drone fielded supports #Starlink even as secondary payload because the angular velocity exceeds Starlink specs on existing terminals.

  • Most drones fielded by #Ukraine are close-range multicopters that drop mortar rounds vertically into trenches, they don't have any #SATCOM, they barely have a video feed on 5,8 GHz...

@mastodonmigration @GottaLaff Obviously, all #SATCOM is insecure.

  • X-Band - based #MILSATCOM use proprietary encryption systems.

  • The best in terms of #COTS AFAIK is #IridiumPTT which does #AES256 over the air (if not the entire #IridiumNext system except legacy services) but that is a fully-managed solution with custom, embedded hardware.

  • Whereas most commercial satellite Internet is insecure af, tho I'm shure Ukrainians know how to setup their own #VPN!

Continued thread

Issues aside it's now 15 years since I started using #Tor / @torproject & @guardianproject / #Orbot on #Android full-time.

Because in #EDGEland they yeet users to 64kBit/s if not even lower to 16kBit/s past paid bandwith and instead of properly renegotiating the bandwith, they trottle connections by reducing the packet rate / dropping packets, making it as #laggy as a #GSO-based #SATCOM connection!

  • On top of that, almost all #MNO|s & #MVNO|s illegally use RFC1918 Address space, *espechally 10.0.0.0/8 for #CGNAT, thus bricking #VPN|s and sadly @BNetzA doesn't really give a damn!

#WhatsMissing:

A modern competitor to #OperaMini with:

Why?

OFC since #Opera #Mini needs a trustworthy proxy backend any "#clone" would need an #OpenSource'd & #SelfHosting-capable #backend (similar to @ActionRetro 's #FrogFind .com as it breaks #E2EE.

Needless to say it would be a godsent for anyone stuck on #EDGEland and slower speeds (i.e. #SATCOM like #Iridium)...
