How do both technologies differ with respect to throughput and Round trip time
The answer will vary time to time.
There are many versions of both specially WiFi.
The wimax is the extension of wifi. The wifi is a local area wireless data network while wimax can cover a whole town in case of MAN and a whole country in case of WAN a wide area network. Both networks are data networks with ip core.
The maximum bitrate for wifi ranges from 2-54 Mb/s according to the earlier wifi standard, and even the new wifi standards may have much higher data rate a hinted by Abdulaziz in the next comment on my post. Wile the maximum bit rate for wimax is up to 134 Mb/s according to the earlier standards and may be much higher in the newer issues of standards as hinted by Abdulaziz in th next comment. Thank you Abulaziz.
The propagation delay in wifi is small since the propagation distance is about 100m and case of wimax it is about up to 7 Km. The propagation delay= propagation length / the speed of light C. C= 3x10^8m/.

wish you success
I modified my post according to the note of Abulaziz about the mot recent standards. I woulld like to thank Abulaziz.
Dear Abdelhalim,
Kindly note that the maximum rate for wifi is more than in the range of hundreds on MB/s. The link you provided is since 2004 ( more than 10 years old) . Evolution of both technologies happened since that time.
For example 802.11n ( which is already in the market) has max data rate of 600 MB/s (http://en.wikipedia.org/wiki/IEEE_802.11n-2009) and some experimental results showed a throughput between 150 to 300 MB/s. Moreover, 802.11ac published in December last tar and built on 802.11n. can support upto 1.300 MB/s with four streams in 5GHz band with 80 MHz of bandwidth (http://en.wikipedia.org/wiki/IEEE_802.11ac#Theoretical).
WiMaX, in the other hand has higher data rates specially with WiMAX 2 ( or 802.16m) where user can aggregate multiple channels to get a download throughput of up to 1 Gbit/s.
Thank you Abdulaziz for your note. So, i would like that the readers see that your note complements my post.
