With the added backhaul bandwidth now available with 802.11n, wireless meshing has come of age. An 802.11n Wireless Mesh Network can enable a range of applications that were previously cost prohibitive or impractical.
Among these are: providing ubiquitous client access in outdoor spaces between buildings atschools, universities, hospitals and other large campuses, as well as indoors in large uncarpeted areas such as transportation terminals and warehouses; enabling wireless video surveillance and much more.

The Trapeze 802.11n wireless mesh solution allows a fan out up to six mesh APs, and three hops.
Self-Healing Wireless Mesh
Trapeze Wireless Mesh Networks have their own self-healing, self tuning capabilities, and can also take advantage of controller virtualization to achive NonStop Wireless mesh availability.
If the mesh link becomes obstructed, or the upstream AP goes out of service, the affected mesh AP will automatically find an alternate path. While on the RF side of the equation, the radios used in a Mesh tune themselves automatically for optimal channel, data rate and transmit power, based on environmental conditions or in the event that an adjacent AP goes down, leaving a coverage hole.
