I have had good results running a 902 access point and 902 client, both at 3.3V with Ian Canada supplies and OpenWRT. With OpenWRT, I’m running both radios at 1mW, with the 902’s in close proximity to each other.
There was a notable improvement here vs connecting to my home WiFi network (I attribute this to lower power radios, but that is a guess, not proven)
Next to experiment with the Aruba and the 902 in client mode, trying to replicate some of the findings shared here (and actually better understand the WiFi climate in my home…I have not analyzed this before)
