The paper "Analysis of WiMax Technology" is a great example of a technology case study.   “ WiMAX will make ubiquitous high-speed data services a reality” (Pareek, 17). WiMAX offers to the end-user broadband remote access at data rates of several megabytes per second and within the scope of several kilometres. The similar radio technology will also offer high-speed data services to all roaming terminals such as laptops, PDAs, etc. with an optimized trade-off between throughput and coverage. Eventually, it will enable portable Internet usage, reproducing on the move the same user experience as at home or the office (Bahai et.

al. , 358). The Need for WiMAX The requirement for broadband services is growing exponentially. Conventional solutions that provide high-speed broadband access use wired access technologies, such as traditional cable, digital subscriber line, Ethernet, and fibre optics. It is particularly complicated and costly for carriers to construct and maintain wired networks, particularly in the countryside and distant areas. Carriers are reluctant to set up the required equipment in these areas because of modest turnover and potential. WiMAX will bridge the digital divide in developing countries and transform broadband communications in the industrial world.

Reasonably priced wireless broadband access for all is very essential for a knowledge-based economy and society. WiMAX offers wireless broadband access for all in a very reasonable cost, thus enhancing the quality of life and heighten economic progress.     The Founders of WiMAX The WiMAX Forum, an industry association formed in June 2001, is responsible for developing WiMAX specifications, promoting the technology, and managing the overall certifications of WiMAX products. The organization has a membership of over 370 companies (O’ Driscoll, 48). Working toward harmonization, the Forum selected several bands that will conform to the world’ s requirements.

Essentially, the WiMAX Forum is concentrating on two critical bands, the 2.5GHz or MMDS band and the 3.5GHz band which by far the most abundant broadband spectrum allocated across international borders (Bedell, 485). How WiMAX Works WiMAX is derived from the IEEE or Institute of Electrical and Electronics Engineers 802.16 air interface standard suite, which provides the wireless technology for nomadic and mobile data access. The IEEE 802.16-2004 standard is designed for stationary transmission, and the 802.16e amendment deals with both stationary and mobile transmissions.

WiMAX supports adaptive modulation and programme depending on the channel setting by utilizing orthogonal frequency division multiplexing. Wireless systems cover large geographic areas without the need for a costly cable infrastructure to each service access point (Ahson and Ilyas, 8). The IEEE 802.16 standard is a QoS-rich platform where different access methods are supported for different classes of traffic. Best Effort traffic or BE is one of the most essential of these classes as it represents the mainstream of the overall data traffic. WiMAX employs a reservation-based MAC technology which protocols have been a primary access method for broadband access technologies such as General Packet Radio System, Digital Subscriber Line DSL, and Hybrid Fibre Coaxial HFC cable technologies.         The Benefit of WiMAX WiMAX offers a viable and rapidly deployable substitute to cabled networks such as fibre-optic links, traditional cable or digital subscriber lines, or T1 networks (Ahson and Ilyas, 8).

To give users continuous broadband Internet access at home, in the office, or on the road, WiMAX enables new personal broadband service by utilizing fixed and mobile access in one infrastructure.
