Everyone loves a good puzzle -- this workshop challenges participants with a classic signals mystery: how can we decode the transmission from a basic RF remote and spoof it using our own SDR hardware? In this hands-on, fully interactive session, attendees will reverse engineer a simple, commercially available RF remote. We’ll focus on analyzing and characterizing the signal, then recreating it...

We designed and tested a drone with a wide-band transmitter (down to 30 MHz up to to 1.8 GHz) to measure the complex antenna pattern of radio telescopes. We basically split a VNA in half and flew one half on a drone. Radio telescopes at sub GHz frequencies are often not mechanically steerable. They are composed of arrays of dipoles, troughs, or dishes "pointing up". This makes it challenging...

As wireless communication standards evolve, techniques such as wideband, multi-channel transmission, and high-order modulation are conducted to support higher data rates and throughput. For example, IEEE 802.11ax employs 1024-QAM with up to 160 MHz bandwidth, while IEEE 802.11be extends support to 4096-QAM and 320 MHz bandwidth. In cellular networks, 3GPP 5G NR supports bandwidths up to...
