Re: [WIRELESS-LAN] Powerline ethernet as uplink to an outdoor access point
We used such a connection for a short term linkage - less than six months - and it worked well. The limitation was the speed of the powerline linkage.

RE: Wow vision veos: Will products using Miracast be an alternative?
Unfortunately, enterprise wireless vendors are just sticking their heads in the sand about this, much like they initially did with Bonjour. When Wi-Fi Direct was first announced, I asked my vendor about their strategy on this. Their response was that they did not think this would impact the enterprise. I reminded them that Higher Ed must support many home use devices too. They had no further response. I expect that until there is a groundswell of disgruntled enterprise wireless customers., the vendors will not respond.

Re: [WIRELESS-LAN] Powerline ethernet as uplink to an outdoor access point
I looked into this about a year ago, and found that it would not work on our campus, but the way our lights are set up the lines to the lights are not hot when the lights are off. There is no switch in our lights: if there's power, the light is on. If there's no power, the light is off. I could put a powerline adapter in, but it would only work from late evening to early morning. But that's just how our lights are set up, and ymmv Joel Coehoorn Director of Information Technology York College, Nebraska 402.363.5603 jcoeho...@york.edu *The mission of York College is to transform lives through Christ-centered education and to equip students for lifelong service to God, family, and society* On Tue, May 28, 2013 at 4:49 AM, Harry Rauch rauc...@eckerd.edu wrote: We used such a connection for a short term linkage - less than six months - and it worked well.

Re: [WIRELESS-LAN] Wow vision veos: Will products using Miracast be an alternative?
We had a departmental IT person who insisted on trying SIX simultaneous Miracast connected TV's in the same classroom. According to our spectrum analyzer, Two Miracast devices chew-up 80% - 90% of the available duty-cycle (they do this whether the display is static (Power Point Slide) or active (You-Tube stream)). When we got to four Miracast connections we began to have picture quality issues, and bandwidth available for others in the area was near zero. We talked him into using just one, and we recommended to campus that users avoid it, but there's not much we can do to stop it. -Neil -- Neil Johnson Network Engineer The University of Iowa Phone: 319 384-0938 Fax: 319 335-2951 Mobile: 319 540-2081 E-Mail: neil-john...@uiowa.edu On 5/28/13 6:54 AM, Joshua Coleman josh...@housing.ufl.edu wrote: From my testing with a Nexus 4 and Netgear PTV-3000 using wireless and miracast (while it may do horrible things to the sprectrum and destroy batteries) it works fine.

Logitech makes Power line Ethernet modules that support PoE for their security camera products.

Re: [WIRELESS-LAN] Controlling Bonjour Zones
Airplay support is a work in progress and there is no location control. I don't know if the RFC will bear fruit, but I think individual vendors will try to come up with their own solutions to gain a competitive advantage. Aruba has announced some location-based advertisement thing but it is vaporware at this point I think. For those who want building based or other network segregation models anyway that may be fine, but for those that don't re-architecting a network for airplay zone control isn't very attractive. In our case there aren't that many AppleTVs on campus, and we aren't officially supporting it anyway, so it isn't an issue now. People understand that it is experimental but appreciate that it works nonetheless. The fact that it is usable and reliable is a great thing, and we'll look forward to see what developments for zoning come down the pike.
