Introduction to WiMAX

Slide 1: Introduction to WiMAX Satish, for MoMo Hyderabad Chapter

Slide 2: What is WiMax? • WiMax (Worldwide Interoperability for Microwave Access) is a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL. • The technology is specified by the Institute of Electrical and Electronics Engineers Inc., as the IEEE 802.16 standard.

Slide 3: Relation of Wi-Fi and WiMax • WiMax eliminates the constraints of Wi-Fi. • Unlike Wi-Fi, WiMax is intended to work outdoors over long distances. • WiMax is a more complex technology and has to handle issues of importance such as QoS guarantees, carrier- class reliability, NLOS. • WiMax is not intended to replace Wi-Fi. Instead, the two technologies complement each other.
