GSM là viết tắt của "Grams per Square Meter", tức là số gram trên mỗi mét vuông giấy. Đây là cách đo lường định lượng giấy, được sử dụng trong ngành công nghệ giấy để phân loại các loại giấy dựa trên khối lượng của chúng trên mỗi mét vuông....
Jeśli instalujecie #DIY#LTE z anteną zewnętrzną kierunkową (tzw. #ODU lub antena na kablu, lub 2 kablach) to może wam się przydać mapa i wyszukiwarka #BTS (czyli stacji bazowych operatorów #GSM, masztów).
Kompas w telefonie pozwala ustawić kierunek "zgrubnie", warto później sprawdzić wskazania poziomu sygnału w routerze/modemie by "dopieścić" ustawienie kierunku.
W zależności od przeszkód terenowych, nie zawsze najbliższy BTS obsłuży wasz modem najlepiej. Warto pokombinować. Również raz ustawiony może z czasem stać się nieoptymalnym, np. przez zwiększenie ilości urządzeń abonenckich. Warto wtedy pokombinować z innymi dostępnymi. Podobnie operatorzy oferują w danej lokalizacji różną jakość. Warto dobrać odpowiedniego.
🆕 blog! “Solved! "Access Point Name settings are not available for this user"”

Android's user-hostile interface never fails to disappoint! I was struggling to get a new eSIM working. I could make and receive calls / texts, but data just wasn't connecting. I tried rebooting, flipping to aeroplane mode, changing bearer, manually selecting the network. Nothing!
Then, I remembered my ancient GSM knowledge. All mobile networks need an APN - Access Point Name - in order to connect to data services. Tucked at the bottom of the SIM settings screen is the "Access point names" option. I tapped on it, and got this unfriendly error message:
THIS IS A LIE! What it really means is that the phone doesn't have an APN listed for this specific SIM.
If you click on the + button in the top corner, you'll get to a screen where you can add your APN details manually. You'll need to get these from your mobile operator. But that's not quite all! In order to save the APN, you need to tap the ⋮ button and select "Save":
Rescued yet another old smartphone (Palm Treo) whose rubery plastic has become sticky/goo-ey (de-polymerization) by using an ultrasonic bath with Tickopur TR14, a chemical intended for removing flux residue from circuit boards #retronetworking#palm#gsm
last, but not least, pySim-shell is getting GlobalPlatform SCP02 support; we also had a number of GlobalPlatform commands implemented, but so far no secure channel. I hope SCP03 follows soon. https://gerrit.osmocom.org/c/pysim/+/35462#gsm#simcards#osmocom
Just finished reading the first chapter of "The Everything Blueprint" by James Ashton. The book is about the history of ARM, and the first 24 pages are an excellent summary of the role of #microchips in today's society/economy, the role of #Taiwan, the "silicon shield" theory etc. - not news at all for somebody like me, but an excellent write-up of what everyone should know about the topic.
as the book continues it also covers how TI combined its DSP with an ARM core to create the first integrated baseband chipset for Nokia GSM cellphones, and how that high integration density led to low-power, lightweight phones ahead of the competition. #retronetworking#gsm
“#Apple has no intention to support #Google’s proprietary extensions to #RCS that allow for #E2EE end-to-end [#encryption, which is a feature of Apple's #iMessage]. […] Apple caving and deciding to support [RCS] will expand, rather than contract, the amount of messaging that is not E2EE.”
Just like with #eCall + banning #anonymous#Prepaid#SIM cards basically making a #GSM#tracker mandatory in #cars under the dalse claim to do "roadside assistance and distress calls" when other options would've offered the same at far less cost, better privacy and better coverage...
Because if one has an accident with no withnesses or other traffic coming for minutes if not hours, chances are it's some rural road with no #GSM (or #3G / #4G / #5G reception at all...
Of course I'm very concerned about all #blackout of #communications from #Gaza & inability for #journalists to report to public, from the ground. My bigger worries about this intentional communications blackout is that it affects all #HumanitarianAid organizing communications & all on the ground #emergency#rescue communications. Those are the most important communications ATM for all civilians & aid workers, trapped under constant siege bombardment.
@msquebanh AFAICT, connectivity of the most critical parts is still up and running.
#UNHCR and others have multiple #SATCOM links and with line-of-sight to #Egypt connectivity to their #Mobile networks is still possible and working, espechally near #Rafah...
#GSM allows about 38km LOS connectivity, so abusing a #Satellite dish and shoving an #LTE stick should provide connectivity to #Israel|i and Egyptian Networks anywhere with LOS to a tower...
Forscher: Sicherheitslücken beim Roaming bleiben auch bei 5G eine große Gefahr
Mobilfunker und Regulierer unternehmen laut einem Bericht des Citizen Lab zu wenig, um Sicherheitsschwächen der Roaming- und Abrechnungsprotokolle auszumerzen.
@manawyrm personally allowing #GSM operators to shut down #CSD service is the worst thing.right after the temporary shutdown of #CellBroadcast as that literally killed lives!
@philtel@mediaarchaeologylab But yeah, all mobile phones prior to #2G / #GSM have gotten their certifications and thus permits to be used revoked by regulators and services have ceased to work decades ago.
@taoeffect OFC they could've chosen to implement #eCall in a non-#SurveillanceState fashion by basically using #COSPAS-#SARSAT's 406 MHz band + 121,5 MHz homing signal which would've made the system not dependent on #GSM infrastructure and globally working, but that would've meant people like #Zensursula would've think outside of "How can we accelerate #Cyberfacism in the #EU faster?"...
Eure Aufgabe ist es die gesamte Bevölkerung zu warnen. Also ZUERST Cell Broadcast, DANN NINA/KatWarn. OK?
"Nach den Warnungen über die Warn-Apps "Katwarn" und "Nina", sowie den Deutschen Wetterdienst sei eine zusätzliche Warnung per Cell Broadcast nicht notwendig gewesen."
@mwfc@Hiker@jwildeboer Schalten die Phones dann ihre #GSM/#LTE-Nutzung ab, als Optimierung? Hab in den #Android-Optionen nur gefunden Mobile Daten aktiv zu lassen wenn WiFi verbunden (default aus). Vielleicht wird mobile Telefonie deaktiviert wenn #Wificalling aktiv? Wäre es vom Standard möglich Broadcast durch den Wificalling-Tunnel zu schicken? Der wäre dann natürlich nicht pro "Zelle", sondern global oder nach #GeoIP.

I know about #tails when it comes to computers and #linux.
But is there something alike for #android?
Intuitively, an #USB bootable distro that disable the #GSM based parts and only works on WiFi via #tor while spoofing #mac addresses and comes with a curated list of #apps?
If no, any alternative for time framed anonymity on a mobile device?
