Re: WIRELESS-LAN Digest - 11 Mar 2011 to 14 Mar 2011 (#2011-36)
Some thoughts: 1. The costs cited blew me away - we have surveyed over 8 million square feet in the last 9 years, mostly on campuses and in hospitals. $1,500-$1,800 a DAY, not a floor! 2. A 3 story dorm is probably 3-4 hours including setup and tear down. Another hour to create the reports. 3. While you can buy Ekahau or Air Magnet, you still must understand RF to design around the unique obstacles presented by various types of construction and sources of interference. Unless you are surveying open offices, you WILL find surprises. 4. There is a difference between having signal and having capacity. 5. A good designer is also looking for all the issues associated with cabling the access point (mounting locations, obstructions, cable routes, distances). 6. The test AP requires a controller, a UPS, a means for getting it around and in place, and the knowledge of the software and characteristics of the unit being tested. -- *Ron Walczak RCDD, CWNA/CWSP* ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Wireless Site Survey cost
If you have any resellers/technology partners/consultants you might ask them. Standard consultant fees would probably apply (I've seen $150-$300/hour). If they're good they should be able to survey a couple buildings in a day (which should be less than $1500 a floor). You could also do it yourself. Someone mentioned Ekahau; we use Airmagnet Survey. Its good too have a survey solution for troubleshooting anyways. -- Heath Barnhart, CCNA Network Administrator Information Systems and Services Washburn University Topeka, KS 66621 On 3/14/2011 4:46 PM, Winston Chow wrote: Usually companies don't like to do site surveys because they do it assuming you'll buy APs from them.

HP Wireless components
To those running the Procurve wireless solution. I'm trying to understand what components are needed for procurve system in order to make it work. Are the only pieces involved the Mobility Controller, AP license and Access Points? It seems to simple and I must be missing something.

Re: [WIRELESS-LAN] iPad spontaneous reboots?
We had this problem with a few of our WAN sites. We did not figure out the problem as oppose to a temp fix. We found that when the following conditions existed, the iPads would reboot. - iPads had to be on version 4.2 - WiSM code 6.0.188.0 - VPN involved I moved the WAN ap's over to older code (MESH code 4.2.176.51M) and this fixed the problem. We have plenty of iPads that were on the 4.2 iOS and the 6.0 code on campus (no VPN involved) and did not have any problems. I have not been to the WAN sites since the 4.3 iOS came out so I have not been able to check and see if it resolved any problems.

RE: [WIRELESS-LAN] iPad spontaneous reboots?
There are lots of discussions like this online: http://discussions.apple.com/thread.jspa?threadID=2599544 where it happens with enterprise and home networks alike. in our case Apple didn't hesitate to tell us to go to 4.3. I was in the same location witha pre-4.3 iPad for almost 24 hours and couldn't get the condition to repeat on our standards-based WLAN, nor did it happen again to the users that initially complained. It's always fun when toy-quality wireless devices hit the enterprise WLAN (he said rather sarcastically). I do know that I would have a very hard time justifying making network changes to an otherwise stable enterprise WLAN when the only devices to have problems out of thousands of clients are a few iPads and iPhones.

RE: [WIRELESS-LAN] Wireless Site Survey cost
Have you already selected a wireless product? If not, I think you'd be far better served issuing an RFP for full procurement and installation, with signal guarantees (I'd recommend -68dBm). If you have holes, the contract should be on the hook for it. Take advantage of this economy. Vendors will jump on this. Remember, antennas vary GREATLY. If you do a survey and then bid out and end up with a different product than you conducted the survey with, you could end up with holes. -Brian From: The EDUCAUSE Wireless Issues Constituent Group Listserv [WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of heath.barnhart [heath.barnh...@washburn.edu] Sent: Tuesday, March 15, 2011 9:57 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Wireless Site Survey cost If you have any resellers/technology partners/consultants you might ask them.

Re: [WIRELESS-LAN] Wireless Site Survey cost
Thanks, but I have purchased already. We will be doing this backwards. We are pulling extra drops and leaving 20' coils of cable above the ceilings and then throw up the APs and see what happens. Not perfect but we have been doing alright with that. We have a feel for it and the students report happiness. This summer we will do the survey to tighten things up a bit. I am considering dropping the wired ports as our LAN is past due for a refresh and I do not want to re-invest in the port-per-pillow model.
