    • Free Internet access for all:
      • Access to the Internet must be free of charge. Charges for use of or access to the Piertopier network are expressly forbidden.
      • The network must not be used for commercial or revenue generating activities.
      • The equipment used to provide access must conform to the WIFI standard.
      • Anyone wishing to use the network for a non commercial application must be allowed to do so.
      • Where Internet access is promoted piertopier must be clearly mentioned
      • Wireless access must be provided 24 hours a day.
      • Charges for access to the location of the node are forbidden.
      • Each node must have access to the Internet or an Internet connected Piertopier node.
      • Mesh architecture must be used
  • 7. Technology Overview
    • Locustworld MeshAP
      • x86 hardware
      • Cutdown Slackware Linux
      • Limited documentation
      • NoCatSplash Captive Portal
      • AODV routing
    • Pebble Linux
      • Same hardware
      • Easier customisation (Debian-ish)
      • NoCatSplash Captive Portal
      • Static/OSPF routing
      • Chillispot Captive Portal
    • OpenWRT
      • Cheaper hardware (Linksys WRT54G)
      • Same customisation as Pebble
      • NoCatSplash not stable enough
      • Static/OSPF routing
      • Chillispot Captive Portal
    • DD-WRT?
  • 8. PC/104
  • 9. Sticky
    • GumStix
  • 10. Problems
    • AODV routing
      • Ad-hoc On-demand Distance Vector
      • Tear down link if SNR too low
      • Not so useful if single link
      • Fixed network is neither Ad-hoc nor On-demand…
    • NoCatSplash
      • Cut-down NoCatAuth Captive Portal
      • No user database
      • No accountability
      • No banning bad guys…
    • Chillispot Captive Portal
      • Needs Radius, UAM, back-end database
      • Can’t easily self-provision
    • Documentation
  • 11. Problems
    • Power
      • Gymnasium has lots of big machines and dirty power
      • VIA 500 mini-ITX don’t reboot after powerfail
      • Good site = no power…
    • Weather
      • Seaside = salt
      • Salt & Water = rust
      • Rust = antenna mount vulnerability
    • Vandalism
    • Spam
      • Wiki
      • Forum
    • Time
      • We all have day jobs…
  • 12. Lessons
    • Things we’ve learned
      • Don’t use Adhoc routing in a fixed network
      • Open Source should be Open
      • Allow end users to self-provision
      • Don’t be reliant on any one person
      • Free servers <> stable servers
    • Things to do better
      • Documentation
      • Resilience/uptime
      • Standardisation
      • Work less on the tech, more on the sponsorship/sites
      • Festivals…
  • 13. Festivals
    • Glastonbury Festival – June 2005
    • Glade – July 2006
  • 14. The Future?
    • Maybe there isn’t one
      • Brighton Wireless City
      • FON
    • But if there is…
      • New blood
      • New technology
      • Standard build – simple for home use
    • The future?
      • &quot;The future is here, it's just not evenly distributed yet.&quot;
      • &quot;The best wifi is just that: free wifi throughout, no codes, no charges.&quot;
