After more than seven years in development, design and eleven steps, the
Task Group S now has the mesh expansion of the WLAN standard IEEE 802.11
complete. 802.11s defines how WLAN stations - bases or clients - and
their relationship to build a wireless backbone and forward frames for
participants outside their cell.
The long duration is due to a large extent, many arguments about
details, for example, whether to run the backbone traffic in the same or
a different frequency band should. Furthermore, the time between
departure from heavyweights like Intel and Motorola have set back the
work of the Task Group. Also, the Board of vendor-driven Wifi Alliance -
known by its Wi-seal - has not yet turned to during the development of
the 11-mesh technology from and directed to local, spontaneous wireless
network technology Wi Direct. Wifi Direct is eg Wi-Fi enabled cameras
and color printer by pressing a button coupled spontaneously to print
photos.
On the other hand, for example, the development group has open80211s -
contributed heavily with many entries and corrections to the standard -
the same source, open mesh stack that has been part of the Linux kernel
version 2.6.26. Google has also financed interest in mesh technology and
the company Cozybit example, the driving force behind open80211s, or the
Meraki mesh WLAN manufacturers.
