Question

Which of the following modulation schemes is supported by WiMAX?

(a) binary phase shift keying modulation

(b) quadrature phase shift keying modulation

(c) quadrature amplitude modulation

(d) all of the mentioned

I have been asked this question in an interview.

This key question is from WiMAX in division Wireless LAN’s, Electronic Mail and File Transfer of Computer Network

Answer 1

Right choice is (d) all of the mentioned

Best explanation: WiMAX supports a variety of modulation schemes such as binary phase shift keying modulation, quadrature phase shift keying modulation, and quadrature amplitude modulation and allows for the scheme to change on a burst-by-burst basis per link, depending on channel conditions.
