Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.
Authentication and encryption are not implemented.
There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).
A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.
Drivers that support mesh networks right now are: ath, ral and mwl.
More information at: http://wiki.freebsd.org/WifiMesh
Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.
Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

|
|
|
|
The
|
|
|
|
.Nm
|
2006-03-05 20:57:25 +00:00
|
|
|
driver supports PCI/CardBus wireless adapters based on the Ralink Technology
|
|
|
|
RT2500, RT2501, and RT2600 chipsets.
|

|
.Pp
|
2006-03-05 20:57:25 +00:00
|
|
|
The RT2500 chipset is the first generation of 802.11b/g adapters from Ralink.
|
|
|
|
It consists of two integrated chips, a RT2560 MAC/BBP and a RT2525 radio
|
|
|
|
transceiver.
|

|
.Pp
|
2006-03-05 20:57:25 +00:00
|
|
|
The RT2501 chipset is the second generation of 802.11b/g adapters from Ralink.
|
|
|
|
It consists of two integrated chips, a RT2561 MAC/BBP and a RT2527 radio
|
|
|
|
transceiver.
|
|
|
|
This chipset provides support for the IEEE 802.11e standard with multiple
|
|
|
|
hardware transmission queues and allows scatter/gather for efficient DMA
|
|
|
|
operations.
|
|
|
|
.Pp
|
|
|
|
The RT2600 chipset consists of two integrated chips, a RT2661 MAC/BBP and a
|
|
|
|
RT2529 radio transceiver.
|
|
|
|
This chipset uses the MIMO (multiple-input multiple-output) technology with
|
|
|
|
multiple antennas to extend the operating range of the adapter and to achieve
|
|
|
|
higher throughput.
|
2006-03-13 21:24:28 +00:00
|
|
|
MIMO is the basis of the forthcoming IEEE 802.11n standard.
|
2005-04-18 18:47:38 +00:00
|
|
|
.Pp
|
|
|
|
The transmit speed is user-selectable or can be adapted automatically by the
|
2006-03-05 20:57:25 +00:00
|
|
|
driver depending on the received signal strength and on the number of hardware
|
|
|
|
transmission retries.

Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.
Authentication and encryption are not implemented.
There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).
A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.
Drivers that support mesh networks right now are: ath, ral and mwl.
More information at: http://wiki.freebsd.org/WifiMesh
Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.
Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

|
|
|
|
Host AP mode doesn't support client power save.
|
|
|
|
Clients using power save mode will experience
|
2009-06-05 17:26:15 +00:00
|
|
|
packet loss (disabling power saving on the client will fix this).
