On the 26th of June 2001, Andrew Garton, Sam de Silva, Craig Bellamy met at Toy Satellite for an introduction to wireless networking and free2air from Adam Burns.

This is a report from this meeting outlining free2air's rationale, requirements and recommendations. Rationale

Free2Air is essentially radio/computer networking. The idea is the make bandwidth a community concern, not a commercial one.

Assist in setting up gateways by way of redistributing network load. As at the time of writing, supports three gateways.


  • Wireless LAN card + pigtail antenna (recom. Lucent). Card transmits 30 mwatts supporting up to 11megabits p/second up and down.
  • Antenna - Directional or Omnidirectional.
  • Lightening arrestor.
  • Line of sight with other points of presence.
  • Amplifier - 250 mwatts (not essential, but can increase range/strength)
  • When designing the network visualize what one wants to set up. What do we want to achieve and how do we go about doing it?
  • Plan out a strategy for implementing line of sight points of presence, including ways and means to monitor network usage. Traffic must be mediated to ensure IP connection is not saturated.
  • A partially centralised organisation to support network infrastructure (eg. allocating IP) and to maintain standards.
Legal Stuff
  • 2.4 GHz network cards transmit within an unlicensed range.
  • Use of amplifier may be borderline.
