Sicherheit von 5G-Netzen: BSI veröffentlicht Studie, die Risiken von Management- und Orchestrierungssystemen aufzeigt: 👉 https://www.bsi.bund.de/dok/1112400
Die Detecon International GmbH erstellte in unserem Auftrag eine Studie zur fachlich-technischen Bewertung der Angriffsflächen und -vektoren sowie eine Risikoanalyse des Systems NFV MANO im Kontext eines #5G-Netzes.
#Canada#Cybersecurity#Encryption#Backdoors#5G#Privacy: "Bill C-26 empowers government officials to secretly order telecommunications companies to install backdoors inside encrypted elements in Canada’s networks. This could include requiring telcos to alter the 5G encryption standards that protect mobile communications to facilitate government surveillance.
The government’s decision to push the proposed law forward without amending it to remove this encryption-breaking capability has set off alarm bells that these new powers are a feature, not a bug.
There are already many insecurities in today’s networks, reaching down to the infrastructure layers of communication technology. The Signalling System No. 7, developed in 1975 to route phone calls, has become a major source of insecurity for cellphones. In 2017, the CBC demonstrated how hackers only needed a Canadian MP’s cell number to intercept his movements, text messages and phone calls. Little has changed since: A 2023 Citizen Lab report details pervasive vulnerabilities at the heart of the world’s mobile networks.
So it makes no sense that the Canadian government would itself seek the ability to create more holes, rather than patching them. Yet it is pushing for potential new powers that would infect next-generation cybersecurity tools with old diseases."
@RL_Dane that'll be because 5G used to be a new and groovy thing. Now it's totally pedestrian. The fact I've never had a phone with it says more about me than about 5G.
#GreenPower4Tower: Gesucht sind die besten Ideen für nachhaltige Energiesysteme, um auch abgelegene Gebiete mit leistungsfähigem #Mobilfunk zu versorgen und die Digitalisierung im ländlichen Raum weiter voranzutreiben.
Op dinsdag 25 juni begint de veiling van #frequenties voor snelle openbare mobiele communicatie. Met de #veiling verdelen we landelijk beschikbare frequentieruimte onder de deelnemers aan de veiling. Het gaat om frequentieruimte in de 3450 tot 3750 megahertz (MHz) band, ook wel bekend als de 3,5 GHz-band. Deze band is essentieel voor de verdere uitrol van #5G-technologie in Nederland. De licenties die worden vergund, zijn geldig tot en met 31 december 2040.
With #LTE and #5g mobile connections, the demands on the voltage sources have also increased: In particular high peak currents of approx. 4 A @ 3.7 V and more can push some circuits and the voltage converters installed in them to their limits.
In the event of stability problems with mobile radio modems, it is therefore particularly worth taking a brief look away from the software and towards the hardware. Can the power supply really meet the high requirements? An examination with an oscilloscope shows even the smallest fluctuations in the millisecond range and can reveal possible problems.
In our specific case, we are investigating stability problems with a new modem, which can only be reproduced unreliably. In the video you can see that even small pings have a visible effect (voltage fluctuations of approx. 800 mV) on the voltage source.
Klingt erst mal schlimm. Ist es aber nicht. Denn 5g hat ganz spezielle Anwendungsgebiete, die gerade erst noch entstehen.
Für Otto hat 5g überhaupt gar keine Vorteile im Alltag. Eher noch im Gegenteil: Höheren Energieverbrauch. Also nicht verwunderlich. Sondern nur logisch.
@Matze eine erstaunliche Marketingleistung, finde ich. Etwas erfolgreich verkaufen, das den meisten deiner Kunden keinen einzigen Vorteil bringt 😅
Also nicht falsch verstehen. 5G ist die Zukunft. Das brauchen wir. Aber die meisten brauchen es nicht jetzt. Nur ganz wenige. Da man aber nicht früh genug anfangen kann, weil ja gerade mal LTE nun flächendeckend verfügbar ist... Kann auch irgendwie verstehen, dass man das den Leuten verkaufen muss. Irgendwo muss ja auch Geld für den Ausbau herkomme
#TIL (or re-learnt) that the "5G" in "5G WiFi" is a short form of the 5 GHz frequency for #WiFi networks and doesn't have any connection with #5G (the mobile standard)
Okay, I didn’t expect #5G to actually make a difference sub-6GHz. But here we are, with the fastest Speedtest I ever had on a cellphone.
Btw, this was inside a mall and I don’t even know where the tower is. #networking#internet
I wonder when #5G will become the standard and you don’t have to pay extra anymore to use it with some providers.. Do we have to wait for #6G for that? 😄
That said, I do have the impression sometimes that I’m stuck with (poor) 3G coverage in the city where I believe to have had 4G before. I suspect that some 4G cells have been upgraded to 5G that I cannot use.
