2
THE WORLD IS WIRELESS
  • Communication is crucial, especially in
    developing countries
  • Deploying Mesh-Networks seems to be the solution
  • Infrastructure equipment cost should remain very
    low
  • 802.11 radios are very appropriate
  • Antenna costs still remain high

3
Antennas
Price 349.90
4
Fab Lab WiFi Antenna Projects
  • Window Glass
  • Self adhesive cooper
  • CAD file
  • Flexible low-loss cable, or no cable

5
Isotropic Antennas
Gain 3 dbi
6
Higher gain Arrays
Directivity 1200 H / 300 V- Gain 9 dbi
7
New approaches Planar Antennas
  • Gain gt9 dbi

8
Higher gain planar antennas
Planar structure - Gain gt12 dbi
9
Achieved Targets
  1. Very low cost, 1 or 2 US
  2. Low manufacturing sensitivity
  3. Fab Lab easily reproducible, by unskilled
    Fablabers, using the Fab Lab tools
