CHIPSETS FOR WiMAX DEVICES
Computers are composed of nothing more than logic gates stretched out to the horizon in a vast numerical irrigation system.
—Stan AugartenState of the Art: A Photographic History of the Integrated Circuit (1985)
We have seen that the WiMAX technologies take a quantum leap from the existing wireless and MMDS technologies for delivery of broadband content with quality of service (QoS). The technologies are not only based on OFDM, which provides high resilience against intersymbol interference common in NLOS transmission, but are implemented with very flexible features such as setting up of service flows at connection time, and are maintained despite adverse conditions through scalable OFDMA, subchannelling schemes, ...
