Re: WasabiNet mesh in St. Louis appeared on local TV news!

Hi All,


Thanks for the tips.  I'm actually planning to deploy a couple Ubiquiti 5.8GHz radios this week, a Rocket M and a Nanostation M5, to try things out.

The goal is to build with these a small backbone mesh (~10 nodes) to supply wired uplinks to 2.4GHz mesh devices, i.e. gateways for WasabiNet mesh.  I only plan to have exclusively my own 5.8Ghz radios participate in the backbone mesh; actual end users would still connect at 2.4GHz.

Are there more details on the limitations of mesh topology with the current AirOS+OLSR firmware, in the absence of adhoc/adhemo?  The screenshots below do suggest you do have a functioning mesh with gateway(s)/repeaters.

Also, I happened to find recent mention of Virtual AP support in AirOS v5.3b2 on the Ubiquiti forum:

Well, mostly FOSS at least.

Another sidenote: at the wireless summit in the hacklab we found out that the speed test of AirOS was done from within a kernel module, so... the speed that you get on user space will differ from this of course.

Thanks equinox (Christian)  :)

Re: WasabiNet mesh in St. Louis appeared on local TV news!

I don't think that in the case of p2p links the absence of ad-hoc mode is a major issue, because even in the scenario of 1 master and several slaves, the topology of the backbone doesn't change that often. You can always hook a 2.4 GHz mesh device next to the p2p link. And I don't know if virtual AP makes sense for p2p devices either - you want the bandwidth on the backbone, and usually not share it with clients... but maybe I'm missing some use cases.

Dear ISOC Members, The Internet Society has announced that it is inviting applications for its latest Internet Society Fellowships to the IETF, part of its Next Generation Leaders (NGL) programme (www.InternetSociety.org/Leaders) . The Fellowship programme allows engineers from developing countries to attend an Internet Engineering Task Force (IETF) meeting. As you know, the IETF is the Internet's premier standards-making body, responsible for the development of protocols used in IP-based networks. IETF participants represent an international community of network designers, operators, vendors, and researchers involved in the technical operation of the Internet and the continuing evolution of Internet architecture. Fellowships will be awarded through a competitive application process. The Internet Society is currently accepting fellowship applications for the next two IETF meetings: * IETF 80, 27 March - 1 April, Prague, Czech Republic * IETF 81, 24 - 29 July, Quebec City, Canada http://www.isoc.org/educpillar/fellowship/index.php Fellowship applications for both IETF meetings are due by 17 December 2010. I encourage you to pass on information about this program to individuals involved in your network that have a keen interest in the Internet standardisation activities of the IETF. The Internet Society Fellowships to the IETF are sponsored by Afilias, Google, Microsoft, and Intel. The Internet Society’s Next Generation Leaders programme is sponsored by Nominet Trust, the Association Française pour le Nommage Internet en Coopération (AFNIC), and the European Commission. If you have questions, please do not hesiate to contact Connie Kendig <kendig[at]isoc[dot]org>.

Canadians develop cognitive radio technology

http://www.crc.gc.ca/en/html/crc/home/mediazone/whatsnew/nov08-12_1
After developping  802.22 protocol and having no luck finding interests 
from hardware manufacturers, Canadian researchers have adapted their 
cognitive radio aproach to wi-fi.
Experts, please comment !!!

Playing around with AirOS + OLSRRe: WasabiNet mesh in St. Louis appeared on local TV news!

HI Alex (and list),


Thank you for the link to the Funkfeuer wiki page and images.

I have the modded AirOS images running on a NSM5 and a Rocket M5.  Both devices see each using standard ubnt functionality.

A question, at high level: how does the OLSR patch interact with the existing modes in AIrOS for LAN and WLAN  routing?

E.g. for the "Network" tab, there is Bridge, Router, SOHO Router, and for the "Wireless" tab there is Station and Access Point.

The screenshots from the wiki show one device (the Airgrid) as Router/Access Point.  Are all other nodes set to the same modes, or do some nodes need to be set at Stations/Bridge?

Hi Ulf,

We are using the (OpenWRt-based, with OLSR) ROBIN firmware available from open-mesh.com ron all 2.4GHz devices.  We do this since the OM dashboard is really handy  The access points are Open Mesh OM1Ps, a couple Ubiquiti Bullet2HPs, a Nanostation2, and a large smattering of Engenuis EOC-1650 and EOC-2160 for cost reasons.  

There are about 4 active nodes right now, out of 49 provisioned.  Most nodes just use the integrated antenna or 7dB dipoles, although there are now a couple cantennas in place.

Pictures:

I am happy to hear that reflashing the small Ubiquitis is getting easier.  I've actually had some limited success doing on-the-fly firmware upgrades on the Bullet2HP with the ROBIN firmware, tho I have to SSH into the device and trigger an upgrade manually.

hi ben, very cool, congratulations for you great community wireless project.
how many nodes are in the olsr cloud?
i saw in the news, you are running ubnt hardware, so if you use olsr, you are using openwrt on it?
just yesterday we (some freifunker) finished working on a modified bootloader for the nanostation 2 and bullet 2 to have a bootwait to get access to the bootloader for upgrading firmware
no more reset button pressing on rooftops for upgrading!
good luck for your fiber uplink,

KSDK, a local TV station, recorded this interview with Minerva and myself in May about our OLSR-based wifi mesh in St. Louis, MO USA.  They finally aired it earlier this month, in anticipation of Google announcing their plans for 1Gbit fiber deployments in this country later this year.

The WasabiNet KSDK video from 10/14 is now on Youtube!

I will be gradually posting this link everywhere I can, but feel free to share it yourselves!

that was the plan ;).

not really, the only change i made is to allow to set no default
gateway. By default the web interface enforces you to set a default
gateway. But of course this can interfere with dynamic routing.

all of these should be basically the same. For olsr you normally would
use router mode on alle nodes, AP mode on one node and Station at all
the others.

As with normal wireless setup there is one node configured as access
point and all the others are configured as station. Using router mode
(not bridge) is preferred in most cases (on both sides). But setting it
to bridge is also supported because this may be usefull at times.
Also you have to consider that unfortunately there is no ad-hoc mode in
this version of the firmware. The main reason for that is that the
kernel used by Airos is quite old (2.6.16 i think) and a quite new
version of the driver would be needed to have stable ad-hoc mode. Also
in our network we don't need ad-hoc mode by the nodes running AirOS. We
use OpenWRT on Ubiquity hardware when we need ad-hoc.

regards,
 christian

Is multi-casting video conferencing over IP available for tele-training?

Hello all,

I am looking for open source multi-casting video conferencing over IP addresses system. We have now a hybrid network of wireless and optical fiber in about 100 villages. The purpose is to provide live trainings to people from a classroom, who are living in different villages and in different regions. Therefore two way communication is important.  Please let me know if there is such system available. Also I would like to know if such system can be developed using open source.

Thanks.

Mahabir Pun, Nepal

it surely can -

available open source / free software includes:

http://code.google.com/p/bigbluebutton/ (!)

http://www.vmukti.com/

http://www.dimdim.com/ (note: hosted solution!)

http://ekiga.org/

it is difficult to say, which is the best way to go -

i guess you would prefer a local system (= not hosted somewhere outside
your network), due to bandwidth constraints.

i would be interested to hear what others have experience with and
opinions on.

best,

sebastian

Mahabir,
 
Check the following Google link, it may work for what you are looking for; it's from Google and it's free!

Re: Is multi-casting video conferencing over IP available for tele-training?

Hi Mahabir, it would be really a pity to choose an hosted solution
such as google, there is several options for private solution :

- Rely on an internal pbx such as asterisk with videoconf installed on
the server. Protocol could be SIP

- Build our own http based solution around open source flash media
server such as Red5 using RTMP or http.

I obviously prefer the first solution
