6GHz outdoor use at standard power levels using an AFC is still not available in the USA/FCC yet. Anyone in the USA/FCC land are using either an FCC OET or STA exemption to run in 6GHz as an experiment. Due to these restrictions, it’s unlikely that someone was granted permission to run a very long link. Furthermore…
The proposed EIRP for standard power in the USA/FCC land is 36dBm on both sides of the link. These EIRP limitations along with the SnR needed to achieve 4096QAM severely limit link distance.
The F4600c is capable of upto 4096QAM and has an SFP+ port. I have a short PtP link (.25mi) running in ePTP mode 160MHz that can get around 1.8gbps HDX. For this link, 99% of packets are being sent at 4096QAM.
Eric, thanks for the info. 36dBm EIRP obviously is a problem, 160MHz won’t be available everywhere because it’s huge chunk of the spectrum etc.
Your result is in line what I was expecting and I’m very glad to hear the internals of 4600c are capable to deliver (cpu, networking, pps capability etc). We achieved little bit over 800Mbps on Force400c, 80MHz channel & 1024QAM.
For distances under a mile, 60GHz would be easier and much more future-proof.
