Veraltete Netze weichen für Highspeed-Frequenzen. Jackson und Miles zeigen dir den Weg vom Funkknochen zur KI-gestützten 6G-Technologie.
Best quote from Mobilfunk im Wandel: Von 2G-Abschaltung bis 6G-Zukunft
“
Jede Generation hat den Alltag ein Stück weit mehr entfesselt: Mit 2G wurden wir mobil erreichbar, mit 4G hatten wir das Wissen der Welt in der Tasche, und 5G fängt gerade an, unsere physische Umgebung zu vernetzen.

Frequently Asked Questions
Die Abschaltung erfolgt primär, um Platz im Frequenzspektrum zu schaffen. Die wertvollen Frequenzen im 900-Megahertz-Band, die eine hohe Reichweite haben und gut durch Wände dringen, werden für die leistungsfähigeren Standards 4G und 5G benötigt. Durch die Umwidmung dieser Frequenzen können die Netzbetreiber die Kapazität und Geschwindigkeit moderner Netze massiv erhöhen, insbesondere in ländlichen Regionen.
Betroffen sind alle Geräte, die ausschließlich über das 2G-Netz kommunizieren können und kein LTE (4G) unterstützen. Dazu gehören sehr alte Mobiltelefone ("Ur-Handys"), aber auch kritische Infrastrukturen wie ältere Notrufsysteme in Aufzügen, Senioren-Notrufknöpfe, veraltete Alarmanlagen und bestimmte vernetzte Stromzähler. Während für einige Industrieanwendungen (IoT) Restnetze bis Ende 2030 geplant sind, müssen Privatkunden ihre Hardware bis Mitte 2028 aktualisieren.
Obwohl 3G neuer als 2G war, galt es technisch als weniger effizient. Es verbrauchte im Verhältnis zur Datenrate viel Strom und belegte wertvolle Frequenzen, ohne den massiven Geschwindigkeitsvorteil von 4G zu bieten. 2G wurde hingegen länger als "Sicherheitsnetz" für die reine Telefonie und SMS beibehalten, da es aufgrund seiner physikalischen Eigenschaften eine extrem hohe Reichweite und Zuverlässigkeit als Fallback-Lösung bietet.
Das derzeit oft genutzte 5G (Non-Standalone) nutzt zwar neue Antennen für hohe Geschwindigkeiten, basiert im Hintergrund aber noch auf dem alten 4G-Kernnetz. 5G-Standalone hingegen verfügt über ein komplett neues, optimiertes Kernnetz. Erst mit diesem "echten" 5G werden Funktionen wie "Network Slicing" möglich, bei dem das Netz in verschiedene virtuelle Scheiben unterteilt wird, um beispielsweise Rettungskräften oder der Industrie garantierte Kapazitäten zuzuweisen.
6G wird als "KI-Netz" konzipiert, bei dem künstliche Intelligenz die Steuerung in Echtzeit optimiert. Technisch soll es Terahertz-Frequenzen nutzen, die Datenraten von bis zu einem Terabit pro Sekunde und extrem geringe Latenzen im Mikrosekundenbereich ermöglichen. Dies ebnet den Weg für futuristische Anwendungen wie holographische Kommunikation, Fernoperationen durch Roboter in Echtzeit und sogenannte "Digitale Zwillinge" von ganzen Städten oder Fabriken.

Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!
@ladyInfinity
I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.
@jayallen
The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.
@Raguipa
What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.
@colonyofcreatorsNGO
I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.
@BeFreed user
It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.
@austinakon
I love this app. Used it for several days and I cannot stop listening. Such a great way to start.
@jcrules328
I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.

@DanielCZ
I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.
@BeFreed user
I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.
@Brad
I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!
@BeFreed user
The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.
@jayallen
BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.
@BeFreed user
At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!
@matteo77
BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
