Interestingly, #Toosheh is not listed on #LyngSat, cuz from what I can read it should be in that MUX on 52,5°E Al Yah 1 @ 11,766GHz (Vertical) with DVB-S (27.500 KSym/s & FEC 7/8).

And it's not as if LyngSat doesn't list Data MUXes or anything (They literally show Satellite Internet Feeds), but even then Toosheh does send a custom screencard as they MUX their data in a way that consumer Sat Recievers will record it like additional audio tracks, which is different from your regular #SatelliteInternet or #Satellite #Data #Feed channels that require custom hardware and settings.

#Datacasting #Iran #Broadcasting

@geist wenn es "#Freiheit" ginge, dann hätte #Starlink die #Spezifikation von Starlink-Terminals als #OpenSource veröffentlicht und würde nicht die niedrigen Orbits vermüllen sondern konsequent auf globale Abdeckung hinarbeiten.

Es wäre z.B. Problemlos möglich für ~ €10k p.m. downstream >99,99% der Weltbevölkerung und >75% der Welt (beides nach Oberfläche) mit einem globalen Dienst (vgl. #Toosheh) zu erreichen.

• Okay das wären auch nur ~ 640kbit/s aber weitaus mehr Durchsatz als #Bitcoin - #Bullshit!

@geist wobei allein der Besitz von #Starlink als #Spionage gewertet wird und Betroffene froh sein können, wenn diese nur temporär in #Evrin #verschwindenlassen werden, statt mit nem Kranwagen öffentlich gehängt zu werden!

• Gängig ist #Toosheh als #Datacasting - Dienst weil wegen der hohen Elevation überm Horizont und Sendestärke nicht nur einfach emfangbar ist sondern auch relativ schwer durch den #Iran störbar... Wobei das ein sich stündlich wiederholendes, regelmäßig aktualisiertes Datenpaket von ~2 GB ist welches mit ~ 640kBit/s im MPEG-Transportstrom verkapselt übertragen wird.

  Does anyone have the full #specifications for IrDA #archived somewhere?

Because I'm looking for a good, short-range protocol that is less complex than #LiFi * for a "digital dead drop".

Most notably because USB dead drops have a shitton of disadvantages as #USB is not designed for that in mind, is extrenmely susceptible to sabotage and vandalism as a #PirateBox *, less complex than #FreedomBox * for #Sneakernet * operations.

Given the IrDA spec is relatively simple on the physical interface, reimplementing it with visible light would allow for more options espechally when it comes to "broadcasting" data to multiple devices when #datacasting like #Toosheh * would be overkill...

How the battle for #democracy will be fought — and won

"The government cut off internet access in parts of Kurdistan, Tehran and elsewhere, according to NetBlocks, which tracks internet outages. Iran’s theocratic rulers apparently intended to keep demonstrators in the dark about protests spreading in neighboring towns and cities. Both WhatsApp and Instagram were shut down.

But a little-known channel helped millions of Iranians stay in the know. A nongovernmental organization in Los Angeles, #NetFreedom Pioneers, had created a method to bypass the internet entirely and broadcast files — text, audio or video — from commercial satellites to anyone with a receiver dish. It is called Toosheh, or Knapsack. The group collected photos and news reports from social media platforms and elsewhere, uploaded them to a satellite and then down to homes in blacked-out Iran. The news was easily shareable on a flash drive."
