INTRODUCTIONThere are basically three different

options:BROADBAND ACCESSWIFI ACCESSDIAL-UP ACCESS

The 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 Receiver

WiMAX 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 & mobile services.

ADVANTAGESBandwidth FlexibilityPricing + Contract FlexibilityQuick InstallationInterpenetration

DISADVANTAGESWiMAX 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

WIMAXWiMAX is a long

range system. WiMAX provides

services analogous to cell phone.

It uses a mechanism based on setting up connections between the base station & user device.

WiFiWiFi is shorter

range system. WiFi is more

analogous to a cordless phone.

WiFi has introduced a quality of service mechanism similar to fixed Ethernet, where packet can receive different priorities based on their tags.

Mobile WIMAX Broadband

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.
