• 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.

What is WiMax?

15

• It is a non-profit industry body dedicated to promoting the adoption of this technology and ensuring that different vendors’ products will interoperate.

• It is doing this through developing conformance and interoperability test plans and certification program.

• WiMAX Forum Certified™ means a service provider can buy equipment from more than one company and be confident that everything works together.

802.16 Overview

17

WIMAX versus WLAN802.16 802.11b(WI -FI) Technical difference

range Up to 30 miles typical cell size

) 4-6miles(

Sub -300 feet)add acess points for greater

coverage(802.16 tolerates greater multipath delay spread via 256 FFT vs 64 FFT

coverage Outdoor NLOS performance standard support for advanced antenna techniques

Optimized for indoor performance ,short range

802.16 systems has an overall higher system gain dellvering greater penetration through obstacles at longer distances

scalability Designed to support hundreds of CPES with unlimited subscribers behind each CPE

Intended for LAN applications ,users scale from one to tens with one subscriber for each CPE device

802.16 can use all available BW ,multiple channel support cellular deployment,802.11 is limited to license exempt spectrum

Bit rate Up to 100 MB/S in 20 MHZ channel Up to 54MB/S in 20MHZ channel Higher modulation coupled with flexible error correction

QOS Built in to MAC voice/video service levels

No QOS support 802.11 is contention based MAC (CSMA/CA) ,802.16 dynamic TDMA-based MAC with on-demand BW allocation

MAC Polling –based MAC layer Contention based MAC
