Broadband wireless access with WiMax/802.16: Current performance benchmarks and future potential.
Dr. Jeffrey G. Andrews - WNCG of UT Austin

The IEEE 802.16 family of standards, and its associated industry consortium
WiMax, promises to deliver high data rates over large areas to a large
number of users in the near future. This exciting addition to current
broadband options such as DSL, cable, and Wi-Fi promises to rapidly provide
broadband access to locations in the world's rural and developing areas
where broadband is currently unavailable, as well as competing for urban
market share. WiMax's competitiveness in the marketplace largely depends on
the actual data rates and ranges that are achieved, but this has been
difficult to judge due to the large number of possible options and competing
marketing claims.  This talk will first provide a brief tutorial overview of
802.16.  Then, based on extensive recent studies, we will present the
realistic attainable throughput and performance of expected WiMax compatible
systems based on the 802.16d standard approved in June
2004 (now named 802.16-2004).  We also suggest future enhancements to the
standard that could at least quadruple the achievable data rate, while also
increasing the robustness and coverage, with only moderate complexity
