Introduction to WiMAX

Introduction to WiMAX Satish, for MoMo Hyderabad Chapter

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.

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.

WiMAX vs. 3G, pros and cons

Cost

Lower equipment cost for WiMAX due to certified products (compare with WiFi)

WiMAX require new infrastructure while HSPA rides on UMTS

Coverage

Roughly the same coverage (average ~5 km)

Performance

Roughly the same performance (average ~2 Mb/s per user)

Market window

HSDPA launches in 2006 while HSUPA will come in 2008?

WiMAX standard set end of 2005 -> first products in 2007

Acceptance

HSPA has a higher acceptance with mobile operator
