WiMax (Worldwide Interoperability for Microwave Access) is a wireless broadband Technology, which supports point to multi-point (PMP) broadband wireless access.
Broadband today—or some call it, broadband Internet—is as important as waterways, railroads and interstate highways of an earlier era
Until now broadband connections either had to be offered by companies that own physical lines to buildings, which meant the telcos and cable operators, or they had to come from expensive satellite links or from wireless broadband systems that didn’t have economies of scale in their componentry. To solve the above problem the technology called WiMAX based on IEEE 802.16 standard is on the way and is expected to provide affordable broadband for all and improve the quality of life. WiMAX is a long –distance fixed wireless solution which is expected to outpace the growth of broadband wireline options as cellular phones have supplanted many land line users.
This paper will provide a very strong introduction about
1. WiMAX technology
2. Architecture of wimax.
3. Standards and scope of wimax technology
4. Its challenges and advantages for end user connectivity and its scope
5. Deployment status of this technology,
Introduction:
WiMAX is defined as Worldwide Interoperability for Microwave Access by the WiMAX Forum, formed in June 2001 to promote conformance and interoperability of the IEEE 802.16 standard, officially known as Wireless MAN. The Forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL".
WiMAX is not a technology, but rather a certification mark, or 'stamp of approval' given to equipment that meets certain conformity and interoperability tests for the IEEE 802.16 family of standards. A similar confusion surrounds the term Wi-Fi, which like WiMAX, is a certification mark for equipment based on a different set of IEEE standards from the 802.11 working group for wireless local area networks (WLAN). Neither WiMAX, nor Wi-Fi is a technology but their names have been adopted in popular usage to denote the technologies behind them. This is likely due to the difficulty of using terms like 'IEEE 802.16' in common speech and writing.
