Hi!
I'm Adrian. I'm a wifi hacker. I worked at Qualcomm Atheros for 18
months on various open and closed source wifi things. I'm also the
FreeBSD wireless developer.
My main focus is FreeBSD but I know a bunch of stuff about openwrt and
the Linux wireless stack and Atheros drivers.
Right now I'm working on FreeBSD support for the latest Atheros chips
and SoCs (the AR933x and AR934x stuff), as well as finishing off the
11n support for TDMA and 802.11s mesh.
I came along to the mesh meetup because being a developer of this
stuff in a vacuum is a bit silly. I've been looking for local groups
who are interested in wifi and want to do strange things with it. This
group seems to be that way inclined. :-) I'm also looking for
victims^Whelpers to test out the long-distance side of this TDMA
support in FreeBSD. It's supposed to work up to dozens of miles, but I
just don't have access to places to mount equipment to test. I'm
hoping that I can find some people here who are willing to help me
with this. I can provide the wireless hardware; all I need here is an
internet hookup and places to mount stuff.
I'm happy to help out any way I can.
If you're all interested, I can do some talks on how this stuff works
and how long distance links work/don't work.
Thanks!

Hello meshers!
My name is Charles Wyble, and I've been involved with mesh networks for about 10 years.
A couple years ago, I cofounded a non profit called the Free Network Foundation. We've been working on making the Ubuntu lts of mesh. We call it FreedomStack.
You can learn more at http://www.thefnf.org . We are trying to participate in every single us based mesh community, and provide assistance, connections etc. We also are securing ipv6 space and building relationships with carriers , so that mesh networks can provide internet transit if they so desire.
Very excited to be on this list. I'm based in Austin TX, our hq is in Kansas City. We helped a local non profit (connecting for good) overbuild the evil Google Fiber prisim net, with a free wifi network. It's rapidly growing to cover all of KC.
FNF doesn't operate networks, we provide operator education and development resources.
Oh yeah, we are working on the GPL for networks , called the Network Commons License. RMS is on our board of advisors.
We also are working on high altitude wifi baloons, first test launch will be August 10th out of Houston.

As my task from this past week for the Mesh group has been to do some more research on tax structure advantages and disadvantages - I wanted to share my excitement about 501(c)(7) with everyone. Social Clubs!
Check it out -- http://www.irs.gov/Charities-&-Non-Profits/Other-Non-Profits/Social-Clubs.
Examples of 501(c)(7) ----
College social/academic fraternities and sororities
Country clubs
Amateur hunting, fishing, tennis, swimming and other sport clubs
Dinner clubs that provide a meeting place library, and dining room for members
Variety clubs
Hobby clubs
Homeowners or community associations whose primary function is to own and maintain recreational areas and facilities
We have the first two nodes mounted, running and connected!
On the mesh map they are "Hearth" and "Adeline Livelabs":
http://meshmap.sudoroom.org/
As you can see, the houses are almost exactly one block from each other on
opposite sides of the street. Each house has a Ubiquiti Bullet 2 HP with a
large omnidirectional antenna mounted on the roof. Unfortunately the only
easy mounting point on the livelabs roof was not near the front of the
house, resulting in the signal being blocked by two large trees on a
neighboring property. We'll move the antenna another day, but for now at
least there is a link.
The nodes are running the batman-adv mesh routing protocols, they can see
each other and we're getting a bit under 1 mbit/sec each way. This is not
great and will be improved once we get line of sight between the antennas.
Ideally we wouldn't use omnidirectional antennas for roof to roof
connections, nor would we use 2.4 ghz routers, but since these two houses
are so close we figured we'd be able to connect them like this and get some
street coverage as well. Using a smartphone we can connect to and use the
mesh from about 1.5 blocks away from each node on adeline street giving us
a four-block coverage area in the north-south direction at least.
The connection is also fine indoors on the first floors of both houses,
even
directly underneath the antenna! More testing is needed to see how well it
covers neighbors houses.

Please add your own notes to this semi-scattered documentation! :)
Remember we are also hanging regularly on #510pen on Freenode IRC!
Attendees
- Chris J, Jenny, Max, Juul, Luis, Adrian, Christie, Thomas
New Action Items
- Add your potential node to the map! - http://meshmap.sudoroom.org
- Get batman-adv running at Hearth node, mesh with LiveLabs node
- Next reportback on an active mesh - Jenny
- Find some tall rooftops for Adrian to test TDMA point-to-multipoint
links
- Research resilient ethernet cable
- Tune the OpenWRT settings on the new nodes for RTS / CTS and ACK
timing
- Brainstorm on name for the mesh!
Old Action Items
- Decide on name (some suggested options further down in the notes)
- Research 501(c)x statuses:
https://sudoroom.org/wiki/Tax_Structure_Research
- Put together a brochure / pamphlet
- Website (contingent on name)
- Splash page design
- Glossary of terms (eg Fresnel zone, Hidden Node problem, etc) on the
wiki - MaxB began: https://sudoroom.org/wiki/Mesh/Terms
Announcements
- Marc & Jenny set up the first two nodes at their home rooftops
Report-backs
- Marc reporting on Seattle Meshnet:
- They are using cjdns and part of Project Meshnet
- Hyperboria: mesh on top of the internet. like Tor.
- Currently running an excellent
- Bay Area Wireless Users Group (died awhile ago)
Misc Notes
- For every 10-20 street level nodes (2.4GHz) there will be one rooftop
(5GHz) node
- Ubiquiti Tough Cable - some batches of them weren't UV-resistant
- Solve the hidden node problem with Non-Violent Communication for
devices (make requests, send acknowledgments)
- Alternatively, this has been solved with TDMA - but that's
currently not available on Linux
- Reflowing electronics - heat up a circuit board at the right
temperature in a toaster oven to melt the solder and enable the joints to
re-form
- Adrian can port OpenWRT onto anything with an Atheros chip!
- Using epoxy or ... - changes the wireless behavior - to manage outdoor
wear & tear
- Conformal coating
- Two options: 1) Keep existing access point / connection or 2) create
an entirely new access point
- Not best idea for repeater node to be primary access point
Crowdfunding Campaign
- WePay currently stands at $1933.00
- 0.7319 Bitcoins!
- Combined, that's $2,004.01!
Potential Local Services
- Local copy of Wikipedia
- Access to Archive.org
- Tidepools interactive map

I think Tyger, but whether because of my name or the Blake poem I'm not
sure!
I must confess that, although cats have more flash, there is something
eminently pragmatic about prehensile.

"xenomorphic tail grafting," eh?
Let me guess: "Xeno" is "foreign" or "other" and "morphic" means it
pertains to "forms" (in approximately the Platonic sense), so is
"xenomorphic tail grafting" what you get when, say, you graft a dog's tail
onto a monkey?
Thanks,
