I'm always having to look up or reference 3GPP specs and at a protocol level, what you can and can't do for Diameter/GTP-C/PFCP/MAP/SBI, so I made a Pokèdex for protocols: protocoldex.omnitou.ch

Learned today that around 1990, Mercedes-Benz briefly offered a "mobile office" package for the W126 S-Class that included a fully functioning printer, scanner, and fax machine built into an armrest.

NBN’s $3bn fibre revamp is great news but don’t Australians now care more about price than higher speeds?
The demise of NBN’s fibre-to-the-node technology is welcome but making the internet more affordable would have a much bigger impact

Submarine cable signal repeater (1950s) enabled the first submarine telephone cables by amplifying signals. A cable revolution took off right as the space age emerged & there was a debate about whether cables or 🛰️ would be the mainstay of global telecom. Ultimately both would work in tandem

Really interesting podcast - 6G "realism" isn't popular, but Webb has a long track record of getting it right, and makes the point that operators lobbying for more spectrum for 6G are just hedging their bets - better to have it available and not need it than need it and not have it.
