Разбираемся с необычным видом терминалов

Физические терминалы сейчас встретить маловероятно. Однако, чем будет являться GSM модем, работающий через асинхронный последовательный интерфейс для, например, компьютера. Настроим модем и разберёмся в терминологии модели ME(Mobile Equipment) - TE(Terminal Equipment).

Dacht je dat jouw 5G soms traag is? 🤔

Op deze dag in 2000 startte KPN de GPRS-pilot in Nederland. De geboorte van écht mobiel internet, al was het toen nog tergend traag! ⏳🤯

Wat was de allereerste telefoon waarmee jij op het web zat?

#GPRS #Technostalgie

For over a decade #MobileInternet in #Germany has been so abysmal that I'm still using @torproject / #Tor (or rather @guardianproject #Orbot ) as a #PerformanceProxy¹ for mobile browsing, messaging and social media.

• It's really absurd how we're still in #EDGEland!

Schöner #38C3-Talk von @manawyrm zur Technik der Übertragung von Klingeltönen und Betreiber-Logos an die alten #Nokia-Klassiker.

Ich habe nie ein #Jamba-#Sparabo besessen sondern im Gegenteil versucht, alle WAP-Dienste und anderen Kostenfallen möglichst schnell abzuschalten, aber der unfassbar nervigen TV-Werbung konnte man damals kaum entgehen.

Die Technik mit binären #SMS, #WAP, #WML und den nötigen Gateways, die damals nötige waren weil die Handys nicht genug CPU-Power hatten um die XML-Daten lokal zu parsen, sind aus heutiger Sicht auf jeden Fall faszinierend.

A #PSA for anyone living, staying, entering or even travelling to/from #Australia:

Apparently, #Australia decided to mandate it's #GSM systems to be shutdown because some #GalaxyBrainChair wanted to yeet #2G & #3G and demand everything to use #4G & #5G when in fact #VoLTE support is spotty at best and #EmergencyCalling oftentimes is explicitly hardcoded to not use #WIFIcalling or VoLTE as providing #triangulation and #LocationData via #SS7 is a desired feature when someone calls EMS, Fire Dept or the Police for help...

• So essentially #tourists and anyone who hasn't an explicitly fully VoLTE-functional device they tested and verified to also do #EmergencyCalls via VoLTE are fecked with no reception when they need it the most!

• This WILL KILL PEOPLE!!!

As much as we want to bitch about #GSM & #GPRS / #UMTS being #outdated and #inefficient, there are reasons to at least keep 2G available - ranging from lower power consumption to higher resilience in emergency situations.

• #NewZealand for example does shutdown non-#EmergencyCalls during severe #Earthquakes so that people trapped and/or in need of urgent assistance can get through to dispatch operators and everyone else has to get in line and take a number aka. use #SMS or if existing #Internet to say "I'm fine!"...

• If the Ozzies really need that juicy #UHF #SubGHz #Spectrum it's totally feasible to instead change the #allocations and reconfigure #CellularNetworks to use lesser bandwith for 2G (i.e. only keeping the absolute mininum of channels available for any service) and thus clear up space...

And to add insult to injury, Australia passed a #NorthKorea|n-alike #CellPhone #ImportBan for any device that doesn't do i.e. the bespoke proprietary garbage that i.e. #Telstra, #Vodafone and #Optus do with the #baseband modems of their #branded devices...

Seriously, which #TechIlliterate dickhead decided it's a good idea to do that #3Gshutdown in Australia without even a basic 2G network up and running at all?

• At least #Switzerland [AFAIK] still has #3G up and running (tho it would've been wiser to do it like #Germany and keep #2G as emergency fallback with it's functions like #CellBroadcast....
