apologies also from me for cross-posting and commenting on a rather old
thread -

just wanted to add

that we ve tried to maintain a little media coverage archive on this
case here: http://write.less.dk/?p=49

no claim to be complete - just meant for those who continue to be
interested in the development of this.

(pls add if you have stuff we ve overlooked!)

recent developments seems to indicate that this will backfire for ICASA
and become a turning point rather than yet another depressing defeat for
social networkers.

Re: Preflashed FOSS mesh router history ...

Hi all,
All the nodes work on a single channel. What about the thoroughput in 4-5 nodes network (nodes can see each other)?
Is it possible to setup a node as a wireless client to get internet from wireless isp and then with other one share it?

Dear all, We have been using the open-mesh routers since may 2008 and have a nice 40 node mesh going in London SE8.. thats Deptford for those familiar with London. Its taken a lot of energy and patience to hold the network together so far and we are very keen to find a stable solution to work with throughout 2009. I heard from Mike the other day confirming delivery of 20 of the newest router so we can test and report back on our experiences in the wild. If you are interested to see more and hear of our progress try http://own.spc.org. Does anyone else here use Open-Mesh.. how are you getting on..? easy James Juergen Neumann wrote:

hello from copenhagen -

sharing the respect and thanks to all that have been involved in
developing the open-mesh product (hw and sw),

however we have to say that after testing a batch of 20 nodes,
we were not very pleased - on hardware level.

stability problems, dropouts, need for powercycles, unstable RF output
over the various channels, etc

i tried to find time at the ICTP recently to measure this thoroughly,
and document - but didnt.
some of the reasons for the odd behavior are known, others not.

at the moment, in that price class i d prefer the Ubiquitis.

but, to underline again,

no disrespect at all for the great work -

maybe we were just unlucky and caught a monday batch.

i d also need to add that we tested the nodes in an area of extremely
dense 802.11b/g ..... 50+ accessible networks in my living room, ...

(and the open-meshes are vulnerable to that)

best to all,

Network Valuation

From /. [http://rss.slashdot.org/~r/Slashdot/slashdot/~3/JU4poe9oOCI/article.pl]

"A new fundamental law of economics has been formulated by Rod Beckstrom, former Director of the National Cyber Security Center. In Words: The value of a network equals the net value added to each user's transactions conducted through that network, valued from the perspective of each user, and summed for all. It answers the decades-old question of 'how valuable is a network.' It is granular and transactions-based, and can be used to value any network: social, electronic, support groups, and even the Internet as a whole. This new model or law values the network by looking from the edge of the network at all of the transactions conducted and the value added to each. One way to contemplate the value the network adds to each transaction is to imagine the network being shut off and what the additional transactions' costs or loss would be. Beckstrom's Law replaces Metcalfe's law, Reed's law, and other concepts which proposed that the value of a network was based purely on the size of the network (and in the case of Metcalfe's law, one other variable)."

The device is AFAIK essentially the same sold as the first generation 
Fonera AP, hence it shares the same design flaws regarding thermal 
instability, PCB layout and RF filter design. When you open it you'll 
see that it is using a linear voltage regulator which just burns off the 
difference between the supply input voltage and the internal voltage - 
the energy loss and heat emitted is significant. The device will 
occasionally lock up just because it is overheating. The Madwifi driver 
used may be unstable. Felix Fietkau has fixed this for OpenWRT in late 
2008.  There is a unnecessary coax which is soldered to the board 
because the designers were not smart enough to put the RF input/output 
of the electronics close to the RF connector.

Mesh networking with Nokia Web-Tablet N810

Hi!

A while ago there was a posting about the DUMBO project, which included 
the idea to use Nokia Web Tablets in a mesh with Olsrd. I wrote that the 
Web Tablets use a WiFi chipset from TI (Texas Instruments) which doesn't 
support ad-hoc mode, because someone owning the old N770 told me so.

I have bought a Nokia Web Tablet N810 as an upgrade for my old Sharp 
Zaurus SL-5000, since I refuse to use a PDA not running Linux. The N810 
uses a Connexant chipset (Connexant bought Harris semiconductor a couple 
of years ago, they are the manufacturer of the great Prism chipsets) 
which does support ad-hoc mode without any issues. I was running it for 
days in our local Freifunk mesh network, and I have experienced no 
problems whatsoever.

So it makes a perfect mobile mesh device for surfing the web, Skype, 
VOIP with SIP. Price in Germany is now 200€ from cheap retailers. The 
WiFi range of the device is awesome. The only issue is that running 
WiFi/mesh all the time will drain the battery in approximately 4 hours.

Currently I'm using Olsrd. Batman 0.3.X doesn't work yet because it 
needs policy routing enabled in the kernel and the "tun" kernel module 
which is missing in the web tablet Linux distribution. So I will need 
some extra hacking to get a up-to-date batmand running.
