10. Difference in MAC Layer: MAC layer is an essential part of an OSI model. It defines communication procedures that a protocol uses. Wi-Fi’s MAClayer uses CSMA/CA protocol which is not connection oriented while that in WiMAX is connection oriented.
Wi-Fi does not guarantee any QoS but WiMax will provide your several level of QoS. Wimax wi fi.
What does WiMAX do? To keep it simple, the WiMAX technology allows us to send data from one computer to another computer via radio signals. In mostcases the downstream computer is the desk top or laptop computer in your home. The upstream computer is tied to a radio transmitter at a base stationthat sends and receives that data. That upstream computer may tie directly to the Internet, or it may be tied to the central office or other basestations and computers, and may use copper, coax, or even another link of WiMAX.

Our wireless networking expert explains the differences between WLAN, WiMax and Wi-Fi and provides an excellent tutorial on what separates Wi-Fi from .
It would seem that every new technology appearing on the scene utilizes wireless techniques. Wi-Fi is no exception. Whether you are perched on theside of a hotel bed, sipping coffee in the corner Starbucks, or flying at the speed of sound, you are connected. And that's what it is all about.

Wimax wi fi WiMAX technology provides a path (similar to a wire) for data exchange between an end-user and the world-wide web. In this case, thesignals are transmitted through the air via high-frequency radio waves (in the microwave part of the spectrum).
New licensed spectrum is being made available for WiMAX and other technologies NOT including WiFi — for example, the valuable 700MHz frequenciescurrently used by analog over the air TV. WiMAX could have a good run because it is allowed to operate in that efficient spectrum while WiFi willeventually run out of the pitifully little spectrum that's been allocated to it. That's policy and politics and not engineering but could still be areason for WiMAX success. wimax wi fi.

WiMAX is not a technology, but rather a certification mark, or 'stamp of approval' given to equipment that meets certain conformityand interoperability tests for the IEEE 802.16 family of standards. A similar confusion surrounds the term WiFi (Wireless Fidelity),which like WiMAX, is a certification mark for equipment based on a different set of IEEE standards from the 802.11 working group forwireless local area networks (WLAN).
WiMAX Wi-Fi and WiMAX are brothers, of sorts. They both define data transmission schemes. But as we all know there are vast differences betweenbrothers. Application, range, modulation scheme, mobility: these are all examples. In some cases there are great similarities, in other vastdifferences. wimax wi fi.
