Extension of Propagation Models for WiMAX


Simultaneous Prediction on Multiple Heights


  • Fixed WiMAX:
    Heights relative to roof top level for optimization of the heights of subscriber antennas.

More details can be found here.

Multiple prediction heights above roof tops
for the installation of subscriber antennas
on top of the buildings
 

  • Mobile WiMAX:
    Multiple prediction heights (on multiple floors) inside buildings to guarantee sufficient coverage on all floors inside the building.

Multiple prediction heights inside a building

on multiple floors.

Adaptive Control of Prediction Height  

Very important for fixed WiMAX:
  • Prediction for pixels in streets: 
    Prediction height(s) must be relative to ground (e.g. 1.5 m above ground) 

  • Predictions for pixels inside/above buildings:
    Prediction height(s) must be defined relative to the roof top level for installation of antennas above roof tops and to determine the best height for the antennas (e.g. 1 m, 2 m,  and 3 m above roof tops).
    Negative relative heights are also supported to determine the coverage below the roof top height if the subscriber antenna is mounted on the wall of the building.
Of course the prediction heights for both cases can be defined individually. And the definition of multiple heights are also supported.

Wide Frequency Range
 Fixed and mobile WiMAX networks can be applied in a wide frequency range (from 3 GHz up to the 60 GHz region). Highly accurate prediction models are therefore mandatory to handle these challenging multi-layer indoor,  outdoor and even combined simulation scenarios (multi layer CNP ) without re-calibration with measurements for each frequency range.
