  1. Calculation For Wireless Links Onno W. Purbo Onno@indo.net.id

  2. Practical References • http://www.ydi.com

  3. Needed Calculation • System Operating Margin (SOM). • Free Space Loss (FSL). • Fresnel Zone Clearance (FZC). • Antenna bearing, antenna down tilt, and antenna down tilt coverage radius.

  4. Some Conversion • Meter = Feet * 0.3048 • Km = Miles * 1.609344 • dBm = 30 + Log 10 (Watts) • Watts = 10^((dBm - 30)/10) • MilliWatts = 10^(dBm/10)

  5. Free Space Loss

  6. System Operating Margin

  7. Fresnel Zone Clearance

  8. Distance & Bearing

  9. Antenna Tilt Angle

  10. Down Tilt Coverage

  11. mWatt vs. dBm
