Conclusion


 * 11.0 CONCLUSION**

In this topic, WiMAX can be summarized as new technology which is:

i. WiMAX offers very high spectral efficiency, particularly when using higher-order MIMO solutions. ii. The WiMAX physical layer is based on OFDM, which is an elegant and effective technique for overcoming multipath distortion. iii. WiMAX is similar to the wireless standard known as Wi-Fi, but on a much larger scale and at faster speeds. iv. WiMAX supports a number of advanced signal-processing techniques to improve overall system capacity. These techniques include adaptive modulation and coding, spatial multiplexing, and multi-user diversity. v. WiMAX has a very flexible MAC layer that can accommodate a variety of traffic types, including voice, video, and multimedia, and provide strong QoS. vi. Robust security functions, such as strong encryption and mutual authentication, are built into the WiMAX standard. vii. WiMAX defines a flexible all-IP-based network architecture that allows for the exploitation of all the benefits of IP. viii. WiMAX is based on a very flexible and robust air interface defined by the IEEE 802.16 group.
