WiMAX - Summary
We have covered just the very basics of WiMAX in this tutorial. There is plenty of good reference material available out there that you should refer to become a master of WiMAX. Please check WiMAX Useful Resources chapter of this tutorial for more information on WiMAX.
Here is a quick recapitulation of the points that we discussed in this tutorial −
WiMAX is based on a very flexible and robust air interface defined by the IEEE 802.16 group.
WiMAX is similar to the wireless standard known as Wi-Fi, but on a much larger scale and at faster speeds.
The WiMAX physical layer is based on OFDM, which is an elegant and effective technique for overcoming multipath distortion.
The physical layer supports several advanced techniques for increasing the reliability of the link layer. These techniques include powerful error correction coding, including turbo coding and LDPC, hybrid-ARQ, and antenna arrays.
WiMAX supports a number of advanced signal-processing techniques to improve overall system capacity. These techniques include adaptive modulation and coding, spatial multiplexing, and multiuser diversity.
WiMAX has a very flexible MAC layer that can accommodate a variety of traffic types, including voice, video, and multimedia, and provide strong QoS.
Robust security functions, such as strong encryption and mutual authentication, are built into the WiMAX standard.
WiMAX defines a flexible all-IP-based network architecture that allows for the exploitation of all the benefits of IP.
WiMAX offers very high spectral efficiency, particularly when using higher-order MIMO solutions.
WiMAX Forum™ is an industry-led, non-profit corporation formed to promote and certify compatibility and interoperability of broadband wireless products.
WiMAX Forum Certified™ products are based on a single global standard IEEE 802.16 enabling complete interoperability worldwide.
What is Next?
IEEE 802.16 products are in the final phases of commercial development with initial trial deployments already underway. So be ready for a new wireless revolutionary phase.
