Hands-on deep dive into roaming and mesh performance

What’s the secret of good wireless coverage? Overprovisioning of APs and extenders? Proper operation of a wireless mesh? Band steering and roaming of the stations?
In this seminar we show what the latest testing reveals about common AP/extender systems, such as Netgear Orbi and Google Wifi. We look in-depth at the roaming, mesh, band steering and load balancing test methods.
Our presenters are acclaimed wireless test experts from SmallNetBuilder.com, dot11 Labs and octoScope. The tests they demonstrate were performed in the octoBox personal testbed and in a test house.
