Rand Thanks, I had not read Princeton’s pt of view on it yet. I wish we had such a statement on our website. I am well aware that many authorities have ruled that RF wasn’t a health hazard. However convincing the res hall management is still an ongoing process. Students all want good Wi-Fi but nobody wants it in their room and there is also a concern that the cost of moving APs depending on who gets what room might be costly.

We had around 3 that were knocked off of the wall. This academic year, we renovated 4 rehalls with a full 702w deployment (~500 APs), and haven’t seen any drop offline yet because of physical damage. It is a bit early in the year and Spring Semester will probably be a better representation of how many will get knocked off of the wall, but we have been pleasantly surprised thus far as to how few are being damaged.

That’s an interesting topic as here we’re used to ceiling mount APs that are generally out of the way. However, we have a few hallway phones (admittedly higher on the wall), and probably 15%-20% get damaged or knocked off the wall every year. Would the students be any more careful about APs at outlet or desk level?

In most of our residential buildings, the data ports happen to be right behind desks that are provided by ResLife and the desks have covers in the back that essentially would bump against the WAP. Not to mention the fact that as furniture gets moved around, there is always the potential of knocking down the WAP. I wonder how has already deployed them in a similar fashion and what the experience has been? If you end up using them, I’d be curious to see how things work out. Best, Hector Rios Louisiana State University From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Devyn Moore Sent: Tuesday, October 25, 2016 9:49 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: [WIRELESS-LAN] Question about Cisco 1810w APs in residential buildings All, Our housing department wants us to look at these for wide-scale deployment in 11 residence halls within the next 2-3 years due to cost reduction in cable installation with our previous designs. This will be a one AP per room deployment utilizing current wiring infrastructure, where Aps were previously in the hallways (2600, 3500). We’re planning to configure the cells to a lower transmit power as well as assigning channels based on zero occupancy with 20MHz channels. Our ability to get into these buildings in order to resolve rogue issues is severely limited already because we are required to have a Residential Technician (from the housing department) with us when visiting student rooms. That’s only going to get worse when we lose visibility that we currently have with our current deployments in the halls. We’re also not planning to enable the ethernet ports because those aren’t in scope for the Proof of Concept due to crashed timelines provided by the department. We’re currently running 8.0.133.0 and have been incredibly stable (no AVC, no IPv6, 802.1x for primary SSID, web auth guest). We don’t use ISE, but use FreeRADIUS for wireless auth. We’re running two pairs of Hot/Standby 8510s with a mixture of 2600, 2700, 3500, 3600 and 3700 series APs, but would like to start integrating 2800 and 3800 series APs – separate from the housing request. I am targeting 8.2.121.7 for our upgrade in order to get around some bugs that I’ve seen mentioned here as we also start testing 2800/3800 in our environment. Has anyone had any issues with 1810w in dense cell deployments like residential hall buildings? Issues with damaged devices due to installation locations on wall approximately 1.5ft (45cm) from the floor? Have there been any issues with SSO HA with 8.2.121.7? Anything else you’d like to share about the 1810ws?
