RE: [WIRELESS-LAN] chargeback for WiFi calling [was: WIFI calling on iPhones with AT]

[Peter T Murphy]

Related, but different: what we are discussing here is how we can build or 
reinforce our infrastructure so that the telcos can avoid investing in better 
infrastructure (e.g. DAS in our buildings).  Has anyone investigated getting 
investment from the telcos for what we are doing here?

I understand that the students, faculty & staff are our csurtomers, but our 
customers are paying the telcos for service, which we are helping them to 
provide.  Where is my cut?

Are there regulatory reasons why we cannot, or should not?

And really, what would be the point of doing QOS in this case when 99% of the 
end to end connection is out of your control?

No, we do not implement QoS for any network functions.

Yes, along with the Wi-Fi calling options from the other carriers as well.

The different carriers deal with this in different ways.  At least in AT's 
case they ask the user to register an address to be used, and IIRC they also 
will prefer the cellular network for any 911 calls.  But I wouldn't place too 
much stock in my recollection to be authoritative.

Of related interest to us is collecting technical information/documentation on 
how the different carriers actually implement Wi-Fi calling in terms of what 
DNS lookups they do, what IP ranges they use to establish their VPN 
connections, etc etc.

RE: Handling Non 802.1x Devices on the Enterprise Network

[Peter T Murphy]

Let me guess: TVs and gaming devices for the living spaces, right?

We have an SSID for only those devices that appears only in the residence 
buildings. Authenticated device registration for each MAC address is manual 
while we implement something better. We *have* been denying registrations for 
devices which we recognize as capable of 802.1x, but that may be gone with the 
technical process to replace the current manual.

Current annoyance: chromecast, which expects both pieces to be on the same 
broadcast domain, unhindered by APs with device isolation turned on. (It's the 
new vendor-agnostic AppleTV)

We are trying to figure out how to handle non 802.1x devices on our enterprise 
network.  We are a Cisco shop and currently are broadcasting 4 SSIDs including 
a guest SSID that is non 802.1x.  We are concerned with how to give access to 
non 802.1x devices in our residence halls.  We were wondering how others are 
tackling this issue.

For printers and scanners that you support, how do you authenticate the 
devices' access to the net?

Re: [WIRELESS-LAN] Wireless Projection System- revisited

[Peter T Murphy]

Wayne State has looked at some of these solutions recently. The two 
connectivity options  for most seem to be (a) PTP wireless between the 
projector and client, and (b) projector connects to a configured SSID.  
We rejected the PTP configuration, because we cannot imagine that the 
presenter would be happy to sacrifice her/his network connectivity (too 
many presentations include URLs or other external content). The problems 
with having the projector connect to the SSID include (a1) the fact that 
the projectors (to date) have no way to authenticate, other than being 
known MAC addresses, and (b1) the client software and the projectors 
that we've looked at require L2 connectivity, as discovery between them 
is based on broadcast (multicast?).
   One question we've asked the community interested in these is So, 
when Distinguished Presenter from Big Name Institution arrives moments 
prior to presentation time, how amenable are they when you tell them 
they need to install this (client) software on their laptop? And, does 
the client _work_ on their laptop?

Often, these are very ad hoc- the individual has their own projector 
and wants to buy some device like this (just one example) 
http://www.lindy.co.uk/80211g-wireless-vga-projector-server/32499.html to 
pop into service wherever they happen to be. Among the concerns that 
these things bring is that they tend to have fixed power that is far 
too strong for the area they serve, and in a dense wireless microcell 
environment they can be disruptive.


We have cobbed together some solutions where we provide an IOS-based 
AP at low power as the “wireless gateway” (grandiose term) in some of 
these scenarios, but am wondering if anyone has found an off-the 
shelf presentation system that has variable power on the wireless 
side and is a more “enterprise” fit?

Re: [WIRELESS-LAN] Wireless Management

[Peter T Murphy]

While http://www.wayne.edu has AMP (and find it to be pretty god at what
it does), I will be even more impressed when we can move back toward
'something' that manages the WHOLE net (e.g. HP OV), not just one facet
(APs).  Having to remember which platform manages which part of a
network of any size is a pain.
 You might find a better management system for just one vendor's
equipment, but as your system grows you will need to manage different
products. Having one management platform saves equipment, software and
staff training costs when you acquire new wireless units.
