The difference now is that consumer hardware and network connectivity have become ubiquitous and with it the end users are now far more tech savvy than ever before. The once previous line between consumer and enterprise technology has vanished.

re: Tablets Cause Wi-Fi Stress: Truth And Fiction
Nobody seems to know what kind of MIMO chipset the Kindle Fire HD has (e.g. 1x2:2, 2x2:2, etc). It could very well be a 1x1:1 with two antennas for simple MIMO diversity, and that would yield exactly the same problem for Tx as an iPad (1SS devices saturate the medium quickly).

Aerohive's system uniquely supports bi-directional band-steering, meaning that we can set the client percentage (or count) per radio and have the AP decide how many of each client lands on each radio. In addition, we support load-balancing across APs. This alleviates the need for the client devices to exhibit their own band steering behavior.

Great article Kurt! Loved it.

Hope this helps.

No setting to force 5 GHz, the only way I can think of to do this is by brute force. Make sure your 5 and 2.4 bands are on separate SSIDs and then delete all 2.4 SSIDs from the Wi-Fi Network list. Of course, this will drop you entirely off the network (or fall back to cellular if you have a capable device), so it's a poor option. I wouldn't fault just Apple here though, I suspect that Android does the same thing. I do know that Chrome OS is also pretty agressive about finding a 'preferred' Wi-Fi network with signal and locks on even when a faster one becomes available. I agree that having the ability to prioritize networks and have the device periodically poll for a higher-priority one (unless of course it's on #1), would be a great feature for all mobile devices.

Can you set your iThing to not downshift, or to try and go back to 5 GHz as soon as possible? It seems like that would be a worthwhile setting for Apple to include.

Hope you're right about MIMO Fritz. The Fire HD does manage pretty good battery life according to the reviews I've seen, of course it is only a 7" display and doesn't have a power-sucking LTE radio. Regarding corporate WLAN capacity, the problem isn't so much in the aggregate as at the edgeGǪtoo many mobile devices in one location, say your cafeteria or main conference room, can consume all the available airtime if you only have a single AP.

I wonder really how much capacity today's typical corporate wireless LAN is consuming anyway. I'm betting there's still a decent amount of headroom there. Also, on the MIMO thing -- Amazon's new Kindle Fire HD supports MIMO and I think we'll start to see more tablets doing the same.
