Re: [WIRELESS-LAN] Controlling Bonjour Zones

2013-05-28 Thread Mark Duling
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.

RE: [WIRELESS-LAN] Power line Ethernet as uplink to an outdoor access point

2013-05-28 Thread Smith, Todd
Logitech makes Power line Ethernet modules that support PoE for their security 
camera products.  The cameras are made to be installed outdoors and the modules 
have weather-resistant connectors on them.  I use one for wireless and it works 
pretty well.

Subject: [WIRELESS-LAN] Powerline ethernet as uplink to an outdoor access point

Has anyone tried to use a powerline ethernet product as a backhaul to an 
outdoor wireless access point?  The thought crossed my mind today that that 
might be a possibility.  The remote AP can be powered by a light pole and 
electrical service to that light comes from a breaker inside one of our 
buildings.  If the uplink came from the same place the power does, that would 
make the installation a lot simpler I think.  Now that I've had the idea, I 
wonder...is this a good idea or a bad idea?

Re: [WIRELESS-LAN] Wow vision veos: Will products using Miracast be an alternative?

2013-05-28 Thread Johnson, Neil M
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.

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

Degraded Wi-Fi throughput w/ Apple iOS6 clients w/ 11n/CAC during BA neg CSCud67358 (

2013-05-28 Thread Hurt,Trenton W.
CSCud67358 Bug Details
Degraded Wi-Fi throughput w/ Apple iOS6 clients w/ 11n/CAC during BA neg
Symptom:
Apple clients running iOS 6.0.1 may experience degraded throughput when
attempting to download media rich content such as video.
Apple clients running iOS 5.x or earlier do not experience the issue under
identical conditions.

Apple support has observed and analyzed the issue, and has confirmed non
compliant CAC behavior with iOS 6.0.1 software. Apple intends to correct the
issue in forthcoming firmware updates.

This release note will be updated with code fix specifics when available.

Conditions:
Apple iOS 6.0.1 client connected to Unified Access Point at 802.11N data rates
with Video Call Admission Control (CAC) enabled.

Workaround:
Disable 802.11N support or disable Video Call Admission Control (CAC).




RE: Wow vision veos: Will products using Miracast be an alternative?

2013-05-28 Thread Osborne, Bruce W
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.

The whole idea behind Wi-Fi Direct is to be able to stay connected to a
