This document provides an overview of WiMAX technology, including defining WiMAX as a wireless broadband technology based on the IEEE 802.16 standard. It describes fundamental WiMAX concepts such as the base station, subscriber station, modes of communication including line of sight and non-line of sight. The document also outlines benefits of WiMAX such as faster speeds than broadband, wireless connectivity without cables, and broad coverage compared to WiFi hotspots. It concludes that WiMAX can bring broadband access to more users in rural and developing areas.

- 1. WIMAX TECHNOLOGY SHAFAQUE GHAYAS SATTAR 3rd YEAR ECE 11030
- 2. Outline of the Presentation • Introduction • IEEE 802.16 standard • Fundamental WiMAX Concepts • Mode of Communication • Development & Evolution • Benefits Of WIMAX • Features of WIMAX • Advantages of WIMAX over WIFI • WIMAX vs. 3G • Conclusion • References
- 3. WIMAX stands for Worldwide Interoperability for Microwave Access WiMAX refers to broadband wireless networks that are based on the IEEE 802.16 standard, which ensures compatibility and interoperability between broadband wireless access equipment WiMAX, which will have a range of up to 31 miles, is primarily aimed at making broadband network access widely available without the expense of stringing wires (as in cable-access broadband) or the distance limitations of Digital Subscriber Line. What is WIMAX?
- 4. Base Station (BS) The BS is the node that logically connects wireless subscriber devices to operator networks. The BS maintains communications with subscriber devices and governs access to the operator networks. WIMAX TOWER • A WiMAX tower, similar in concept to a cell-phone tower - A single WiMAX tower can provide coverage to a very large area as big as 3,000 square miles (~8,000 square km). Fundamental WiMAX Concepts
- 5. Subscriber Station (SS). The SS is a stationary WiMAX-capable radio system that communicates with a base station, although it may also connect to a relay station in multi-hop relay network operations. WIMAX RECEIVER A WiMAX receiver - The receiver and antenna could be a small box or PCMCIA card, or they could be built into a laptop the way Wi-Fi access is today
- 6. NLOS(Non line of sight): Similar to Wi-Fi, built in or external radio device which connects a host to WiMAX Tower. LOS(line of sight): Higher speed backhaul connection used between WiMAX towers to extend network. MODES OF COMMUNICATION
