New blog post: Demodulation of the LTE uplink. A self-contained hands-on walk through the analysis of the uplink signal. The post assumes some knowledge of OFDM, but no previous knowledge of LTE. We demodulate some PUSCH slots that I have recorded from my phone. (1/9)
ALT A waterfall of an LTE signal, showing different blocks corresponding to uplink transmissions using different time-frequency allocations. Both data and control transmissions are visible.

From the minds of @ktemkin, @GSGlabs.
LUNA isn't just a USB 2.0 protocol analyzer, it's also an open-source USB core for FPGAs that's now been tested on dozens of hardware platforms, including some of my own! 😁

The @acm_wisec tutorials will start in 20 minutes (6:25pm UTC). In the first session, @bastibl shows how to decode signals from a car key with GNU Radio. More tutorials are scheduled tomorrow: sites.nyuad.nyu.edu/wisec21/…

We are back online - and will never be able to thank the Chaos Computer Club enough for that.

After a ton of cleanup and documentation, this is now fully open source:
The BLE radio: github.com/newhouseb/onebitb…
The building blocks: github.com/newhouseb/alldigi…
Since I basically learned RF from scratch to build this, I spent a lot of time documenting, which I'll preview below...

A study from Korea showing why indoor dining is unsafe and why airborne transmission matters. Case B infected case A from 6.5m (~21 feet!) away in *just five minutes*, and case C from 4.8m (15 feet!). Footage shows no interaction—and only those in line of air flow got infected.

So ridiculous. Donald must work on his Anger Management problem, then go to a good old fashioned movie with a friend! Chill Donald, Chill!
