Question

An approximately omnidirectional channel model accurately describes fading statistics if directional antennas are employed at the receiver.

(a) True

(b) False

I have been asked this question during an online interview.

My enquiry is from Multipath Shape Factors for Small topic in portion Mobile Radio Propagation: Small – Scale Fading and Multipath of Wireless/Mobile

Answer 1

Correct choice is (a) True

Easy explanation: An approximately omnidirectional channel model accurately describes fading statistics if directional or smart antenna systems are employed at the receiver. Unfortunately, recent measurements and models have shown that the arriving multipath in a local area bears little resemblance to the omnidirectional propagation.
