Software-defined radio (SDR) transforms how we study and experiment with wireless communication.

By processing real signals on your computer, you’ll explore modulation, filtering, and receiver design—skills that extend into modern systems like Wi-Fi, Bluetooth, and cellular.

Whether you’re an engineer or an enthusiast, SDR offers a practical way to understand the building blocks of today’s wireless world.

Linux Is Best

I took things a step further.

Plugging anything into the USB without first unlocking the phone means everything gets wiped.

So even someone with the skills to try and brute-force the device by plugging something in would be in for a surprise.

Of course, this is also why everything is saved remotely to a cloud server overseas, outside U.S. jurisdiction.

Hey #TMobile, I couldn't care less if the beta is over! There's rarely a time that the #5g / #4g network wasn't avail. There WAS a time they were both overloaded & therefore #TSatellite didn't kick in! Cos I STILL DID TECHNICALLY have 5g/4g!

What good is #TSatellite if it doesn't take into account real-world scenarios! At least #Apple has #WiFi connection bad? Use #cellular as backup!

What we need is a #WiFi and #Cellular not going through? Use #TSatellite!

THEN I'd pay $10/mo more!

Very interesting applied security research into the #GSMA #eSIM universe, specfically the use of the JavaCard VM with its questionable security architecture depending on an off-card bytecode verifier in the context of the eUICC which inherently contains eSIM profiles of different [competing] mobile operators, each of which can install arbitrary Java applets into the same eUICC. #GSM #3GPP #cellular #simcards
