DesignMode

  • geo coordinates can be entered manually
  • the distance between the selected coordinates will be calculated automatically
  • frequency band can be entered manually 
  • rain rainfall rate can be entered manually or set to the ITU recommendation 

...

  • by the ITU recommendation (ITU-R P.837-7)
    • The Digital Map of rain data from (ITU-R P.837-7) is used (the map covers entire surface of the Earth)
    • The rain attenuation model from ITU-R P.838-3 is used. (dB/km)

View Mode

  • relevant parameters are passed in via the url (from the network map)
    • Geo locations of the two points
    • Distance (when available)
  • the user cannot change the lat/lon values of the link
  • rain rainfall rate is auto-filled (according to ITU.P-R P.837-7)

Loss Calculations

The following loss calculations should be performed by the link calculator:

  • FSPL (dB) (ITU-R P.525-4)
  • Rain Loss (dB)
  • Gaseous Loss (Oxygen and water vapour) (ITU.P-R P.676-12)
  • Dual Polarization loss (H V)

...

Use Casedescription
Link calculation
  • Calculator provides input window for Geo parameter
  • If link data was passed via network map:
    • All parameters, specified by the “link” are
    prefilled
    • pre-filled in the
    formular
    • form (GeoA, GeoB)
    • User can input frequency. If empty “normal” bands are calculated.
  • After clicking OkCalculate, the calculator starts.
  • Output is presented according to input.
  • A Back-end link-calculator is used
