Yes try Tabla Beat Science, Karsh Kale and Niraj Chag.

Maybe even Asian Dub Foundation although that might not be electronica.

You can pack many bits into a constellation point. Think 1024 QAM.

Most new licensed band 6, 11, 18, 23 GHz radios these days are 1024QAM capable. For 80 GHz the hot new thing is radios capable of 16/64/256QAM at varying code rates.

What's the limiting factor when designing to a constellation? Otherwise, what's improved about the chip or firmware to be able to move from 256QAM to 512QAM?

[walrus01 → Dwolb]

signal/noise ratio is a big one and RSL level. There are even 4096QAM radios now but they need a signal like -51 to operate at their full modulation. Otherwise they ACM down to 1024 (around -62), 256 and then 64QAM.

That's a pretty narrow ledge to stand on @ 800 GHz. Wonder what the FEC regime is?
