wimax or 802.16 is used for metropoliar area access network which means u can service a larger area than a hotspot. and can be used ptp and p2mp .
in p2p wimax can connect nodes in 72 Mbs and a distance of 50Km,but in p2mp the wimax mast can service an area about 13 Km of radius,but wifi or 802.11 has smaller cell ( radio range ) and it needs mesh networking like cellular mobile phone to cover a large are.the maximum speed is 54 Mbs in p2p connection,and it dramatically decreases if users grow in an cellular area.

ppt on integration of wifi with wimax

Wireless Fidelity (Wi-Fi)
The popular term for a high-frequency wireless local area network. The consumer-friendly name for the 802.11b engineering standard. It lets home and office users create wireless local networks, which connect two or more computers to each other and a faster Internet line. This way there is no more poking holes in walls or tripping over bulky Ethernet cables. The Wi-Fi technology is rapidly gaining acceptance as an alternative to a wired local area network (LAN).


WIMAX(World Interoperability for Microwave Access)

An organization founded in 2001 that promotes the IEEE 802.16 wireless broadband standard and provides certification for devices for compliant devices. WiMAX is designed to extend local Wi-Fi networks across greater distances such as a campus, as well as to provide last mile connectivity to an ISP or other carrier many miles away. In addition, Mobile WiMAX offers a voice and higher-speed data alternative to the cellular networks

differentiate wimax and wifi

In short they are two different standards for different function by IEEE.
WiMAX is more like commercial application while WIFI is more like small LAN users which is supposed to be office area network or something like that.

Hi,

Here is the difference between WiFi & Wimax:-

WiFi:

1)-IEEE STANDERED:- 802.11
2)-RANGE:- 300 feet with speed of 54 mbps
3)-Scalibility:- 1-10 with 1 sebscriber each CPE
4)-channel Width:- 20 MHz fixed
5)-bit rate in 24 channel:- 2.7bps can peak 54mbps
6)-primary application:- wireless lan
7)-Dulex:- half
8)-forward error connection:- Convolutional Code
9)-mesh:- Vendor's property
10)-frequency band:- 2.4 GHz & 5 GHz
11)-radio technology:- OFDM 64 channels &Direct Sequence Spread Spectrum
12)-Bandwidth efficiency:- <=2.7 bps/Hz
13)-Modulation:- BPSK, QPSK,16-, 64- QAM
14)-Encryption:- Optional- RC4 AES in 802.11i
15)-http://www.whiznets.com/index.php/wifi-technology.html

Wimax:

1)-IEEE STANDERED:- 802.16
2)-RANGE:- 50 miles with speed of 70 mbps
3)-Scalibility:- 1-100 with unlimited sebscriber each CPE
4)-channel Width:- 1.5 to 10 MHz fixed
5)-bit rate in 24 channel:- 5 bps can peak 75mbps
6)-primary application:- Broadband wireless acess
7)-Dulex:- full
8)-forward error connection:- Convolutional Code Reed Solomon (Viterbi and Turbo decoders)
9)-mesh:- yes
10)-frequency band:- 2 GHz to 11 GHz
11)-radio technology:- OFDM 256 channels
12)-Bandwidth efficiency:- <5 bps/Hz (3.75)
13)-Modulation:- BPSK, QPSK,16-, 64-, 256-QAM
14)-Encryption:- Mandatory- 3DES Optional- AES
15)-http://www.whiznets.com/index.php/wimax-technology.html
