Wireless Monitoring

2017-03-23 Thread Martin MacLeod-Brown 
Hi All

Im just curious as to how sensitive Airwave is to latency? I ask as I would 
like to put our new Airwave solution in our remote DC (typically 6-8ms average 
response time)
We would be looking at monitoring 500 AP's and 2000 connections. Does anyone 
here run a remote Airwave server, or does it need to be on site?

Thanks

institutional strategies for 802.11ah?

2017-03-23 Thread Gogan, James Patrick 
Was wondering if any of you all (particularly the larger research universities) 
have or are planning to develop an institutional strategy for central 
management of 802.11ah technology deployments? Just curious

It's an interesting question. If .11ah comes out as part of the 11ac (or ax) 
APs, central management is mandatory. If they unleash stand-alone .11ah APs, 
that gets interesting, but would still need some form of coordination if the 
technology becomes popular.

Nope --- actually, our regional water utility (that provides water services to 
the campus) is planning on deploying a large number of wireless water meters 
across campus that would go back to their collectors and repeaters, using 
802.11ah.This would not tie in to the campus network at all.   Just 
wondering what issues that might cause us, not that I see any other real

Hopefully their collectors and repeaters are strictly 900 MHz if placed on

emphatic no to 802.11 other-than-ours gear. (But all we need is a free channel!)

We do have a firm commitment from the utility that their equipment will utilize

Wireless Lighting Controls - impact on Wi-Fi or Wi-Fi's impact?

2017-03-23 Thread Williams, Jess 
Our campus Facilities department is looking at a wireless lighting control 
system that uses a "Zigbee based" 2.4GHz wireless protocol.  An example use 
case for this system is a parking garage that has 86 lights which are connected 
using a mesh network, however I can see it spreading indoors at some point down 
the road.  At a minimum, I know this will raise the noise floor.  Does anyone 
have any experience with a similar situation/technology that can share how this 
impacts your campus Wi-Fi or how Wi-Fi has impacted the lighting control 
system, etc?

The product is AcuityControls XPoint Wireless lighting controls
http://www.acuitybrands.com/products/controls/xpoint-wireless#e8f40e39-86a8-4d2e-9072-e8b872bce11b


I'm told by the manufacturer that the default channel used is Zigbee Channel 
15, which is 2.425 MHz (5MHz total channel width).  The channel can be changed.

Vendor says:
"XPoint Wireless Mesh operate a low duty cycle, narrow band (5 MHz wide) 
communications at up to +18 dBm output power, whereas 2.4 GHz Wifi operates at 
a high duty cycle, wideband communications (typical 20 to 60 MHz wide) 
typically at up to +23 dBm (that’s log scale so that’s a 5 dB difference which 
is actually over 3x as powerful as our system). I’ve never once seen a 
confirmed case where our Zigbee based mesh network interfered with their Wifi." 
 They promise it won't interfere with Wi-Fi.

I'd be more comfortable with something that uses 900MHz instead of 2.4GHz.

Vendor documentation:
XPoint Wireless uses a low duty cycle, narrow‐band, Zigbee®‐based 2.4 GHz 
wireless protocol that is not
known to interfere with your 2.4 GHz WiFi or other systems. The low 
communication duty cycle,
combined with clear‐to‐send backoff capability from the IEEE802.15.4 radio, 
typically does not produce
measurable impact to WiFi performance and is usually difficult to observe in an 
RF spectrum analyzer.
Each XPoint Wireless Bridge and associated mesh network (typically up to 250 
wireless devices) can also
be programmed to use a specific Zigbee RF channel to avoid co‐channel 
interference with other installed 2.4 GHz equipment. Zigbee channels 11‐26, 
corresponding with 5 MHz‐wide frequency bands from
2.405 GHz to 2.480 GHz may be assigned to specific wireless mesh networks.

The wireless communication is secured and encrypted using AES 128‐bit 
encryption. The network
protocol includes “replay” protection, where each wireless message is uniquely 
encoded such that it
cannot be recorded and replayed at a later time.

Maximum RF power output is +18 dBm for Zigbee Channels 11‐25, 0 dBm for Channel 
26.
Output power is typically attenuated 2‐20 dB by LED luminaire housing.

Re: [WIRELESS-LAN] Wireless Lighting Controls - impact on Wi-Fi or Wi-Fi's impact?

2017-03-23 Thread Jeffrey D. Sessler 
How much do you care about 2.4? I’d decide that first before spending a lot of 
time on this.

Will it move indoors? The trend seems to be toward DC-powered LED driven by PoE 
switches, so unless it’s a retrofit for conventional high-voltage lighting, I’m 
not sure how much traction it will get.

That said, if it defaults to channel 15, doesn’t that keep it out of the 
typical 1, 6, 11 channel deployment?

The Kaiser hospitals here in California have Zigbee RTLS systems with devices 
installed in every electrical outlet in the building. They also operate an 
extensive private and public WiFi system, so if you’ve looking for information 
on interference, they could be a good reference point. They are a Cisco shop 
for Wireless, so I’d hit up your Cisco rep for a contact.

We’ve been getting some similar requests for things like thermostats and the 
like.  I’m thinking that the opportunity exists for conversations that go 
beyond just frequency band usage and interference avoidance and talking about 
what possibilities exist to move these devices to the 802.11 network itself.  
Obviously that’s not going to work for every situation but I think we at least 
need to try to get ahead of this so that we can be involved in purchasing 
decisions/discussions.

I agree with Mike.  Whenever I’m presented with another “do xx over wifi 
because it’s more convenient” I usually let them know I cannot guarantee that 
my wifi .. which is a requirement for and by the students .. will not interfere 
with their installation.  If they are ok with that, then go ahead.  I’d also be 
concerned about using a consumer-based home automation technology in an 
enterprise environment.  Was X10 not available ;)?

My personal opinion remains .. if it isn’t going to move, it shouldn’t be 
wireless.

All of that being said, maybe this is your opportunity to get more funding to 
move WiFi to 5GHz and leave 2.4 for IoT junk?

I would be concerned about your campus WiFi overrunning the ZigBee operation.  
We have a similar situation with ZigBee probes used to monitor freezer 
temperatures.  Campus WiFi is not heavily used in the kitchen areas so no 
issues to note for either side.

Subject: [WIRELESS-LAN] Wireless Lighting Controls - impact on Wi-Fi or Wi-Fi's 
impact?

Our campus Facilities department is looking at a wireless lighting control 
system that uses a "Zigbee based" 2.4GHz wireless protocol.  An example use 
case for this system is a parking garage that has 86 lights which are connected 
using a mesh network, however I can see it spreading indoors at some point down 
the road.  At a minimum, I know this will raise the noise floor.  Does anyone 
have any experience with a similar situation/technology that can share how this 
impacts your campus Wi-Fi or how Wi-Fi has impacted the lighting control 
system, etc?

The product is AcuityControls XPoint Wireless lighting controls
http://www.acuitybrands.com/products/controls/xpoint-wireless#e8f40e39-86a8-4d2e-9072-e8b872bce11b


I'm told by the manufacturer that the default channel used is Zigbee Channel 
15, which is 2.425 MHz (5MHz total channel width).  The channel can be changed.

Vendor says:
"XPoint Wireless Mesh operate a low duty cycle, narrow band (5 MHz wide) 
communications at up to +18 dBm output power, whereas 2.4 GHz Wifi operates at 
a high duty cycle, wideband communications (typical 20 to 60 MHz wide) 
typically at up to +23 dBm (that’s log scale so that’s a 5 dB difference which 
is actually over 3x as powerful as our system). I’ve never once seen a 
confirmed case where our Zigbee based mesh network interfered with their Wifi." 
 They promise it won't interfere with Wi-Fi.

I'd be more comfortable with something that uses 900MHz instead of 2.4GHz.

Vendor documentation:
XPoint Wireless uses a low duty cycle, narrow‐band, Zigbee®‐based 2.4 GHz 
wireless protocol that is not
known to interfere with your 2.4 GHz WiFi or other systems. The low 
communication duty cycle,
combined with clear‐to‐send backoff capability from the IEEE802.15.4 radio, 
typically does not produce
measurable impact to WiFi performance and is usually difficult to observe in an 
RF spectrum analyzer.
Each XPoint Wireless Bridge and associated mesh network (typically up to 250 
wireless devices) can also
be programmed to use a specific Zigbee RF channel to avoid co‐channel 
interference with other installed 2.4 GHz equipment. Zigbee channels 11‐26, 
corresponding with 5 MHz‐wide frequency bands from
2.405 GHz to 2.480 GHz may be assigned to specific wireless mesh networks.

The wireless communication is secured and encrypted using AES 128‐bit 
encryption. The network
protocol includes “replay” protection, where each wireless message is uniquely 
encoded such that it
cannot be recorded and replayed at a later time.

Maximum RF power output is +18 dBm for Zigbee Channels 11‐25, 0 dBm for Channel 
26.
Output power is typically attenuated 2‐20 dB by LED luminaire housing.

Re: [WIRELESS-LAN] Wireless Lighting Controls - impact on Wi-Fi or Wi-Fi's impact?

2017-03-23 Thread Sullivan, Ryan 
We have several 802.15.4 wireless door lock installations across campus and 
have not noticed interference with our campus WiFi. We were lucky enough to 
work with our customers and the vendor to document where the installations were 
specifically and I believe the vendor stated they were only using channels 
23-25. It is important to remember that 802.11 and 802.15.4 both have channel 
numbers but since the width is different, the channels do not match up. A 
decent doc from Metageek sums the issue up nicely if you want to copy and paste 
it.

Re: [WIRELESS-LAN] institutional strategies for 802.11ah?

2017-03-23 Thread Scott McDermott 
802.11ah is 900MHz only in the US, so that won’t be an issue.

Assuming, of course, it really is 802.11ah. I’ve been looking for any hardware 
to show that 11ah has signs of life and all I’ve seen is some potential 
vaporware from a couple Asian component manufacturers.

Hopefully their collectors and repeaters are strictly 900 MHz if placed on 
campus. I worry about multi-radio gear in these situations where say an 
emphatic no to 802.11 other-than-ours gear. (But all we need is a free channel!)

It will be interesting.

Nope --- actually, our regional water utility (that provides water services to 
the campus) is planning on deploying a large number of wireless water meters 
across campus that would go back to their collectors and repeaters, using 
802.11ah.This would not tie in to the campus network at all.   Just 
wondering what issues that might cause us, not that I see any other real

What are you envisioning as a use for research universities for 802.11ah?

The use case for IoT and consumer is pretty clear. I’m very interested if 
you’ve been approached by researchers with a desire for the implementation of 
.11ah.

RE: [WIRELESS-LAN] 5 GHz Only Admin WLAN

2017-03-23 Thread Jason Cook 
We run 3 SSID"s essentially doing the same thing but with one 5ghz only. It 
wasn't targeted for  devices where we have more control but as workaround to 
devices connecting at 2.4 when there's a perfectly good 5ghz there.

UofA
UofA 5ghz
eduroam

However I don't like the extra SSID. So the pencilled plan at this point is to 
disable 2.4Ghz on UofA, and remove the UofA 5ghz network. Anyone needing 2.4 
can use eduroam. That would be end of year, so we'll see if it actually happens.

We don't advertise on our website anything about the 5ghz only network, so 
there's no huge take-up which is ok as it wasn't meant to be permanent. However 
it's certainly done its job with users on it no longer having the issue of 
jumping back to 2.4 (including me).
