Mesh/20 June 2013
June 20th Meeting Minutes
Attendees
- Chris J, Jenny, Max, Juul, Miguel, Eddan.com, Sam
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 Fresnal zone, Hidden Node problem, etc) on the wiki - MaxB began: https://sudoroom.org/wiki/Mesh/Terms
Misc Notes
- Community wireless vs. Municipal (gov run) or Corporate (eg Google Wifi)
- Hidden Node Problem:
- Request-to-Send and Clear-to-Send
- TDMA (Time Division Multiple Access): https://en.wikipedia.org/wiki/Time_division_multiple_access
- Someone at Noisebridge has worked on this, could maybe help port from FreeBSD to Linux?
Checking out the hardware!
- Don't power them up without the antennas!!
- Need adapters for the external antennas to bullets
- AirGrids can only run on 5.2V max, meant to run off USB
- NanoBridges and AirGrids are 5GHz and will serve as the rooftop backbone of the mesh.
- PicoStations are the street-level routers
Crowdfunding Campaign
- Raised over $1600 in one week! Awesome!
- Legal structure of accepting donations
- Very good accounting
- Should investigate 501(c)4
- Talk to folks at the SELC, recommended 501(c)7
- Talking to Noisebridge and SchoolFactory in the next week or two about umbrella-ing under their 501(c)3
Survey Responses
- FILL IN
- 2/3 like the current logo
Name Suggestions

- The Trunk
- Hive 10
- Orga Net
- Open and Notorious
- Sudo Net
- Oakland Wireless Network (OWN)
- Oakland Community-Organized Resilient Network (OCORN)

Marketing Discussion
- Sudo meant to reflect empowerment to fix it or make it yourself
- Include a brief definition of SUDO at the bottom of marketing materials
- 'FREE WIFI' sign and/or stickers for the mesh
- Adopt-A-Picostation
- COLLATe utf8mb4_unicode_ci for mounting and running a node and link to online marketplaces on the site
Folks to reach out to
- Internet Archive and Brewster
- Kapor Foundation
Report Backs
- Still need to make a protocol decision
- Inventory Tracking! Mycelia Zero should be completed by next week: Decentralized network of tools/objects, projects and people/skills - Access control (choose to share)
- Need a weather-resistant sticker or tagging system - RFIDs?
- MyAssetTag.com - aluminum matte tags - available very tiny (0.25" x 1") in batches of 100 for $32
- 'Property Of' stamps / tattoos to discourage theft
- OpenOakland feedback:
- Someone has a roof in the hills with a view of the airport (and thus LOL)
Outreach Strategy
- Origin of the outdoor mesh could be LOL/SOL/Cycles Bikery
- Would be easier to connect W Oakland
- We could split the hardware 50/50 between West and East Oakland, then run a campaign to reach across the divides in Oakland to connect the two meshes!
- Reach up to Richmond to Internet Archive's awesome node!
Mounting Solutions
- Flower pots! (with plants that won't obstruct!)
- Birdhouses
- On the eve of the rooftop outside would be ideal
- Flags (American or Pirate version)
Firmware
- Directing network traffic is the major technical challenge
- Encourage participants to use BitTorrent clients that support uTP (microtorrent protocol)
- Should have two options:
1. People replace their existing access point (which they donate to us) with a PicoStation 2. People keep their existing access point and add the PicoStation to their setup, which runs off their router
- Folks can also host a rooftop node
- Focus on aesthetic unobstrusiveness
- Set up a way to split the network into several access points: back channel (for the mesh nodes to connect to eachother), open channel (for public connecting) and private channel (for folks in house/etc, more bandwidth, can be secured with password, etc)
- Things to add to the firmware:
- Privoxy! Non-caching web proxy for block "obnoxious internet junk"
- Ghostery (protect from tracking)
- Adblock (allow for easy opt-in)
- Put passwords on the PoE adapters and let people maintain their own node's level of privacy, upgrades, etc
Useful Anecdotes
- Internet Archive has created a super node up in Richmond (~15km from here)
- Chris has used a dish and 4ft antenna like ours and with line of sight reached up to 2 miles
- Chris has created a router with an xbee radio (cheaper, takes less power) hooked up to the serial port to take in different kinds of sensor data
- Air quality egg
- Router w/ xbee unit for additional cost
Needs
- Antennas towers
- Telescoping flagpoles! (suggested by Seattle Meshnet) - up to 20ft, available Harbor Freight for $50
- Wooden blocks with hinges to direct the Picos
- Ubiquiti sector antennas as major backbone points (2 x 2 x) - up to 40 subscribers, with dishes pointing the signal outward in all directions
