Question

Empirical approach is based on fitting curve or analytical expressions.

(a) True

(b) False

I had been asked this question in an interview for job.

The origin of the question is Practical Link Budget Design Using Path Loss Models in chapter Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Right option is (a) True

To elaborate: The empirical approach is based on fitting curves or analytical expressions that recreate a set of measured data. This has the advantage of implicitly taking into account all propagation factors, both known and unknown through actual field measurements.
