What’s up with MIMO?

With all of the recent talk about 802.11n, I am frequently asked to explain what is MIMO and its benefits. I suspect this may require a few blog sessions, so today I thought I’d focus on multipath and antenna configurations. Read More »

There has certainly been a good deal of industry discussion, or should I say a good dose of vendor hype, around the new emerging standard for Wi-Fi, 802.11n. Through all of the wild-eyed claims of performance increases and radical shifts in the world of enterprise networking, I thought I would offer up some humble (or maybe a bit beyond humble) perspectives on the state of enterprise Wi-Fi, the emerging 802.11n standard, and what customers really need to consider on this front: Read More »
