Question

For predicting the field strength in a given service area, it is essential to estimate ______

(a) Polarization

(b) Magnetic field

(c) Height of transmitter

(d) Signal attenuation

I had been asked this question by my college professor while I was bunking the class.

My doubt stems from Diffraction in chapter Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Right option is (d) Signal attenuation

Best explanation: Estimating the signal attenuation caused by diffraction of radio waves over hills and buildings is essential in predicting the field strength in a given service area. In practice, prediction is a process of theoretical approximation modified by necessary empirical corrections.
