Which of the following is the major disadvantage of the Okumura model?

1.	Which of the following is the major disadvantage of the Okumura model?(a) Complex(b) Inaccurate(c) Not practical(d) Slow response to rapid change in terrainThe question was asked in an internship interview.This interesting question is from Outdoor Propagation Models topic in portion Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile
Answer» Correct choice is (d) Slow response to rapid change in terrain Explanation: The major disadvantage with the model is its slow response to rapid changes in terrain. THEREFORE the model is FAIRLY good in urban and suburban AREAS, but not as good in rural areas. Common STANDARD deviations between PREDICTED and measured path loss values are 10 dB to 14 dB.
