Hi Jason, In regards to Ekahau, you can model the AP model before and after in the predictive section. Obviously this is based on a computer model, but should give an indication.
I can't comment in regards to going from AP2xx/3xx to the AP515. But we have gone from the Cisco 2802i to the AP-515 and in the real world the coverage is a lot better with the Aruba in comparison to the Cisco. Modelling this in Ekahau shows similar. We were a really early adopter of AX and chose to turn off that feature due to the amount of corporate managed laptops running the affected Intel chipset. Now AX is more widespread (Lots more client devices) and better information is provided to end users in regards to updating drivers, we are looking at turning the feature back on.

For example, when replacing an AP315 with an AP515, signal coverage was worse, sometimes bad enough to cause service loss in distant locations. We are considering our next wifi upgrade to 802.11ax and are thinking about performing an apples-to-apples wifi survey by surveying our 2xx APs in-place, then performing the same survey with 5xx APs in-place. Has anyone performed such an apples-to-apples comparison with Ekahau, measuring RSSI, throughput, jitter, and latency? Any comparisons of airtime utilization using EyePA or similar? If anyone has experience they can share to help us make a data-driven and informed decision, I'd be appreciative. In a broader question - for those who have moved from .ac to .ax, have you seen measurable increases in quality of service to your community?
