I'm interested in group designing an open API or equivalent over a high speed serial/digital interface to drive a remote Wi-Fi lower MAC, digital PHY, analog PHY, CMOS radio(s) and front end modules. The upper MAC would reside in the fronthaul concentrator and be remote, supporting up to 48 MAC lowers. Hopefully scale to maybe to higher.  Basically, Wi-Fi goes point to point into the fronthaul concentrator, i.e. following the evolution of ethernet switching but without the CAT 5 for the final leash.

The L2TPv3 w/pseudowires used for eCRPI are an analogy. So is DAA of cable plant OSP.

Assume the seriali interface speed is  a minimum of 10Gb/s but will go to 100Gb/s and then likely to 800b/s.  All at very low power and guiding the photons to/from their destinations with last meter wireless.

WiFi control and 802.11 packets would be carried over this interface. 

Can't be a NIC/sun workstation model on these remote radio heads requiring expensive CPUs and way too much power. This will also isolate WiFi radios from  the SoCs and the internal switches, typically found in  todays' APs, which is a bit of a Frankenstein design the industry has adopted for some unknown reasons.

There is HUGE NSF grant coming available concerning wifi, and I was also thinking that applying to ardc might be an option.

Does anyone here still care enough about wifi to want to participate? In my case I would like to gear up mainly to get into and stay
in the wifi8 standardization process in the IEEE, although I am surfacing to fix some bugs and try to make improvements in the mt79 chipset which is thus far, pretty amazing. I am really pleased with OpenWrt on this chip, so far. An OpenWrt one should be arriving any day....

Anyway, a start at a proposal for ardc is here:
