Model calibration with drive tests
Looking for more information about prop model calibration using drive tests?
There is a document only for calibration with CW measurements.
I can manually extract location and RxLev data from drive test but not sure if there will be any improvement on propagation model?
Any experience, hints, docs?

Re: Model calibration with drive tests
Thank you. However, my question was to use existing drive tests (scanner data) and not to go into CW measurements (expensive) ...
Still asking for some exeprience ...

Re: Model calibration with drive tests
Drive test data can in theory be used (and is supported), but the resulting calibration process is impaired due to the various limitations inherent to this kind of data:
- Since drive test data are made on a real network, part of the measured signal is actually due to interference.
- Using directional antennas implies that the propagation calculation strongly depends on the accuracy of antenna patterns, and only the measurement points in the direction of the main beam are relevant.
- Several frequencies are measured for drive test data, although propagation models are calibrated only for a given base frequency.
