How does everyone plan on dealing with Wi-Fi Direct from both a policy and a technology perspective? From an RF management point of view, I can't imagine a situation where it would be possible to individually manage all devices, printers, projectors, etc that can create Wi-Fi direct networks. And while an official policy might be able to steer frequency usage, it would be pretty tough to enforce without an existing sensor/countermeasures infrastructure in place (of which I would also assume 802.11w will eventually make useless anyway).

Yet, part of me wants to recommend it as the "official solution" for screencasting (ie Miracast) rather than fight a losing fight with AirPlay and mDNS over wireless.

My sense is that all TVs, projectors, printers, and BYOD type devices will eventually support it and managing the impacts it will be inevitable. I'd be interested in what each of you are planning and whether or not anyone has done any testing in a production environment.

Regards,

The problem appears to be that AirPlay / Bonjour devices will not play any other games, you accomodate them at whatever cost, or you lose their proponents.

I have issues with wireless video streaming in the first place (it's not the proper media), but going wireless-to-wireless with it is doubling the airwaves cost.  And if you have thin APs and central controller, you're likely doubling your controller traffic as well.  It just DOES NOT FIT an enterprise wireless network.

You can try to drop it locally off of the APs onto the local network, but now you're no longer on the enterprise network... 

WiFi Direct just introduces more interference and airwave congestion.  Not exactly an enterprise solution.

If they would play in 5G where there is some room for competition, perhaps; but it's a death knell for b/g 2.4G.
