Propagation modelling (1)

Integrated propagation model library:CrossWave propagation model (developed by Orange Labs)Standard propagation model (SPM)Okumura-Hata and Cost-HataITU propagation models: 526-5, 529, 370-7 and 1546-2Longley-Rice based propagation modelEtc.

Open interface to external propagation models :

Integration of external propagation models through the Developer ToolkitFull integration of propagation models available from 3rd party developers



SPM is a semi-deterministic propagation model suited for predictions in the 150 to 3500MHz range

It is best suited to GSM 900/1800, UMTS, CDMA2000, WiMAX, and LTE radio technologiesUses Clutter and 3D building dataAutomatic and assisted tuning featuresModels basic indoor propagation

A performance of close to 7 dB of Standard Deviation can be achieved



CrossWave propagation modelFrequency range 200 MHz to 5 GHz Supports all mobile technologiesModels all cell typesSuited for all types of environment

BenefitsHigh accuracy even without tuningRobustEasy settingsGreat performanceSame model for all areas



Propagation model tuning :

Based on CW and drive test data (measurement module required)

Manual tuning using a propagation model editor

Automatic model tuning based on the Bounded Variable Least Squares technique

Assisted model tuning designed for advanced calibration

Measurement-based pathloss matrixesDrive Tests or CW data can be used to improve the propagation calculation accuracy of individual sectors


Measurement module

CW MeasurementsImport , display and analysis of CW dataPrediction/Measurement comparison and statistical analysis (mean & standard deviation)

Test mobile dataImport , display and analysis of test mobile dataGraphical replay on map combined with user-defined graphsCall events display and analysis
