| free2air.org 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, free2air.org supports three gateways.
Requirements
- 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)
Recommendations
- 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.
