<p><b>New page</b></p><div>=Attendees=<br />
*Jenny, juul, substack, miguel, jordan, mark, rody<br />
<br />
=Announcements=<br />
*We've started an IRC channel on Freenode IRC: #510pen - come chat!<br />
*Check the updated wiki at https://sudoroom.org/wiki/Mesh<br />
<br />
=Notes=<br />
*Marc researched Freifunk, which is both a firmware project, group organization and many small meshes throughout Germany: https://sudoroom.org/wiki/Mesh/Freifunk<br />
**Firmware is interesting – community profiles for a) chipset b) language and c) city<br />
**Does the work for you – source code is available.<br />
**As a node, you get a static public IP<br />
*Commotion is based on the Freifunk<br />
**Available on more devices<br />
**Also works with OpenBTS<br />
*OLSR - Layer 3, no kernal module so takes more CPU resources<br />
**Has an Android, Mac, and Windows version<br />
**OLSR has a watchdog which auto-reboots<br />
**Batman-adv is only available on Linux – you could port the protocol<br />
*Hack to run DHCP to have dynamic IP assignments<br />
*How to assign IP addresses: We could only run ipv6 – much larger address space – for random assignments of static IPs<br />
*Hash the MAC address that's stored in a distributed manner<br />
*Planned vs dynamic mesh networks<br />
*Interoperability of protocols – batman as the backbone and OLSR/Babel on top<br />
*Open Mesh<br />
**Pay for faster access<br />
**Small businesses, schools, RV parks etc<br />
*Marc is going to buy a Freestation and some nanobridges ($85)<br />
**Omnis spread the signal too much<br />
**Ubiquiti sells antennas with 90 and 120 degree – this plus a router is $160-180<br />
*Lasers! Temporary permits<br />
*Cell phone networks – you can run up to 100 milliwatts without a license<br />
*Critter (substack)<br />
**Re-sync once connected to the public network<br />
**Spot crowd-voting<br />
*5Ghz Backbone and 2.4Ghz connections between<br />
*batman-adv:<br />
**multi-cast: avoids network saturation, allows for streaming that other nodes can choose to plug into<br />
*Major issue is latency in hops<br />
<br />
=Action Items=<br />
*Art, propaganda, manifestos!<br />
**mesh detected<br />
*Explore batman vs olsr vs robin<br />
*Mesh reading group?<br />
**Start here: http://www.wndw.net/<br />
*Today I Learned? June 8th is available<br />
*Radio show w/ Interviews? Jenny & Alcides<br />
*1 page description of mesh to distribute to everyday folks<br />
*Let's make a mesh!<br />
**Test batman-adv for next week<br />
**Throughput and slow-down over multiple hops<br />
**Signal strength<br />
<br />

*Routers full of money!<br />
