INTRODUCTIONThere are basically three different options: BROADBAND ACCESS WIFI ACCESS DIAL-UP ACCESSThe main problems with broadband access are that it is pretty expensive & it doesn’t reach all areas.The main problem with WIFI is that hot spots are very small, so coverage is sparse.
New Technology WiMAX This new Technology would provide:-That is less expensive than cableMuch easier to extend to rural areasBroad coverage like cell phone networks. WiMAX is a wireless digital communications system also known as IEEE 802.16.
Working There are two parts:WiMAX TowerWiMAX ReceiverWiMAX stations connect directly to the internet with a wired connection.
TYPES OF WIMAXFIXED WIMAX: Fixed WIMAX deployments do not cater for hand off between base stations, therefore the service provider cannot offer mobility.MOBILE WIMAX: Mobile WIMAX implementations can be used to deliver both fixed SAMSUNG MOBILE WIMAX DEVICES & mobile services.
ADVANTAGESBandwidth FlexibilityPricing + Contract FlexibilityQuick InstallationInterpenetrationDISADVANTAGESWiMAX can operate at higher bitrates or over longer distances but not both.Omni directional antennas are used.
BROADBAND ACCESSMany companies are closely examining WIMAX for “last-mile" connectivity at high data rates.The resulting competitions may bring lower pricing for both home & business customers, or bring broadband access to places where it has been economically unavailable.

COMPARISON B/W WIMAX & WIFI WIMAX WiFiWiMAX is a long WiFi is shorter range system. range system.WiMAX provides WiFi is more services analogous to analogous to a cell phone. cordless phone.It uses a mechanism WiFi has based on setting up introduced a quality connections between of service the base station & mechanism similar user device. to fixed Ethernet, where packet can receive different priorities based on their tags.
Conclusion Within five years, we expect WiMAX to be the dominant technology for wireless networking. By that time it will be fully mobile, as well as providing low- cost, fixed broadband access that will open up regions where internet access has no far not been practical.
