It&#x27;s interesting to see the huge channel bandwidths they&#x27;re using to attain this. Advances like this are largely driven by higher sample rate ADCs and DACs becoming more viable in recent years.<p>Edit for clarity: channel bandwidths in the datasheet are up to 2 GHz. Need to close the link at 32 QAM to hit 10 gb before error correction overhead at that bandwidth, which is certainly doable. Also, it&#x27;s interesting to note that they quote 7 gbps throughput @ 1 GHz bandwidth, and 10 gbps at 2 GHz. It implies that they can run at 256 QAM at 1 GHz, but only 32 QAM at 2 GHz, which also makes sense.<p>Having worked in the satellite communications industry, where channel sizes used to be limited to 72 MHz (because of hardware limitations of the spacecraft), getting modems designed to operate on larger channels is no small task. I would love to learn more about the internal architecture of these radios to understand exactly what&#x27;s going on - are they using interleaved ADCs? Is the modulation&#x2F;demodulation being done in an FPGA, or an ASIC?<p>If there are terrestrial microwave engineers on here, I&#x27;d love to hear your thoughts on this!
