This is the kind of stuff I'm curious about.
If the antenna is well designed (good radiation pattern) and the EIRP is limited to FCC limits (100mW by default?) how will it achieve longer ranger? The client device (laptop, cellphone) has a TX power as well that requires some symmetry to achieve the range. I know APs can request clients lower their TX power to reduce interference in high density environments, but I don't know they'd raise it.
As for high density environments, this comes down to the management software and not the features of WiFi chipset? Things like MU-MIMO certainly make sense for high density environments (Ubiquiti sells a series of "HD" suffixed parts that add MU-MIMO), but I'm curious if there are other things other then more radios on more bands.
How many of the more advanced features of Enterprise APs at the mercy of the client WiFi module, firmware, and driver for behaving optimally? I assume a company like Aruba (or really any major player) has a full interoperability test lab. Which client devices work best (Intel?)?
> Most homes don't have more than 20-30 devices on the WiFi. Most Instant access points can handle about 50-60 devices at a time. In my own home, the 5 Ghz band is primarily used due to the open layout and there's a lot less interference on that band in my neighborhood. I'm just using one Instant access point (IAP-215) to cover about 2500 sq ft.
2500 sq ft on one AP is pretty impressive, for the price though you could buy several UniFi APs. I checked out the datasheet[0] for the AP 210 series and was delighted to see some radiation plots at different frequencies.
