I am ...Hi Andrew, thanks for your information here. I am too looking for specific mobile chipsets supporting this Wi-Fi 802.11r. I got to know from that MTK chipsets do not support. As per you there are few Broadcom and Qualcomm chipsets support, but not getting direct information on which all chipsets (chipset numbers) support these. Also would like to understand if this 802.11r support has to be in base mobile chipset or it has to be additional wi-fi only chipset?<br /><br />Unknownhttps://www.blogger.com/profile/08463102819673147784noreply@blogger.comtag:blogger.com,1999:blog-1988432060681510848.post-41022648868527373872013-08-29T10:05:52.725-05:002013-08-29T10:05:52.725-05:00Apple iOS devices support 11r on code version 6.0 ...Apple iOS devices support 11r on code version 6.0 and later. Also several Broadcom and QualcommAtheros chipsets support it, so you could cross-reference the Wi-Fi Alliance Voice-Enterprise certified chipsets with a specific device you may be looking at to find out. I think there is one Blackberry certified too. <br /><br />As for an 11n WGB, you should use an AP from the same manufacturer in Mesh or WGB mode. <br /><br />AndrewAndrew von Nagyhttps://www.blogger.com/profile/12658799453646609565noreply@blogger.comtag:blogger.com,1999:blog-1988432060681510848.post-61624757627886037342013-08-28T14:42:34.000-05:002013-08-28T14:42:34.000-05:00I'm learning much on this blog.

This takes time and degrades client performance, so they only do this periodically or when their SNR drops below a threshold triggering an immediate scan. The 802.11k neighbor information allows the AP to which the client is connected to provide a list of neighbor APs that can handle the connection should the client wish to roam. This allows the client to maintain a list of potential APs to roam to, their channels, and load without having to go off-channel. This is of particular benefit with 5GHz since there are so many 20 MHz channels available. It would take a while to scan all of them by a client. <br /><br />Cheers,<br />AndrewAndrew von Nagyhttps://www.blogger.com/profile/12658799453646609565noreply@blogger.comtag:blogger.com,1999:blog-1988432060681510848.post-28238658804378265892012-12-10T11:02:21.383-06:002012-12-10T11:02:21.383-06:00Good post, but I have a question about 802.11k.

From the client's perspective, why wouldn't it just do a background scan to see who is nearby?<br /><br />Is the purpose of 802.11k to minimize probe requests/responses to gather this information when the AP/controller can provide a more intelligent sublist? What information is provided by 802.11k? Just BSSIDs of candidates or do they also provide the current RSSIs from your client's perspective? Given the list of candidates, how would my client pick the optimal AP?<br />Scottnoreply@blogger.com
