RE: Betr.: Re: [WIRELESS-LAN] Disappointing numbers of 5ghz clients
Now I'm getting curious. We have had 1 and 2 Mbps disabled for years and are contemplating also pulling the plug on 5.5 and maybe 11. We have Cisco WCS, and I'm struggling to find a meaningful way to quantify whether the lower rates are being used and to what extent, without hopping through hundreds of clients individually to see what they are at. Has anyone found any sort of data rate trending/reporting mechanism to use as you turn off legacy rates? Regards- Lee Badman Lee H.

Betr.: [WIRELESS-LAN] Disappointing numbers of 5ghz clients
Jen, We see exactly the same on our wifi-networks. For economy class mobile equipment it'still cheaper to go for 2.4 Ghz radios only + i believe i have read / heard that 5 Ghz radios are also more battery-consuming. For students complaining about wlan performance (either face-to-face or via social networks) we offer the dual band capable use wifi adapters for loan via our helpdesks to experience the difference. Also our faq on wlan describes the advantages of choosing a dual band capable device, but it's an 'uphill battle'. Best regards, Kees. Jennifer Francis Wilson jfwils...@uclan.ac.uk 9/25/2011 4:05 PM Anyone happy with the numbers of 5ghz clients connecting to their networks, compared to 2.4ghz clients? I'm only seeing around 25% of clients on 5ghz, despite having a decent density of dual radio 2.4/5ghz APs with band select switched on. A reasonable percentage of the 5ghz clients are from laptops we loan out which we know connect to 5ghz most of the time. Most clients seem to either not be 5ghz capable or their wireless NICs/drivers aren't choosing the 5ghz signal. (we have 802.11n on both 2.4 and 5ghz, with 20mhz channels on 5ghz and use the same ssids on both bands) Jen. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. --- Op deze e-mail zijn de volgende voorwaarden van toepassing: The following conditions apply to this e-mail: http://emaildisclaimer.avans.nl --- ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Disappointing numbers of 5ghz clients
We are testing a practice of having the 5GHz N package have a separate SSID - one with -N to try and focus on the higher bandwidth. Results have been mixed due the issue of seeing the stronger signal as well.

Re: [WIRELESS-LAN] Disappointing numbers of 5ghz clients
I'm seeing about 10% of our clients using 5 GHz in our ResHalls and that's about it. I don't have complete 5 GHz deployment across our campus though, and were I do I still don't see the numbers improving any.

Re: [WIRELESS-LAN] Disappointing numbers of 5ghz clients
As a comparison, we have dual band radios in all locations. We have disabled 802.11b and enabled band preferencing on all APs. I manually manage radio transmit power settings and as a general rule, the 5G radio is set to operate 3dbm higher than the 2.4G one. As I type, this is how our network breaks down today: bgn: 38% g: 20% a/n: 22% a: 2% unknown: 18% (clients that are no longer active but haven't timed out of our system yet) I too am disappointed that dual band is not the standard. However, as we're really only trying to get a 50-50 split between 2.4 and 5g, I suppose the optimist in me says we're half way there at 24%. My stats also tell me that 60% of all our associated users this week had an Apple OUI, which presumably means dual band capable (iPhone 3gs and up/iPad are dual band as well as recent MacBook Pros). I think there are more gains to be made in rf design (beefing up the relative strength of 5g signal strengths), but mostly waiting for the market to catch up like everyone else.
