What is WiMAX?
Worldwide Interoperability for Microwave Access (WiMAX) is the common name associated to the IEEE 802.16a/REVd/e

standards.

These standards are issued by the IEEE 802.16 subgroup that originally covered the Wireless Local Loop technol ....etc

Abstract
IEEE 802.16 standard and WiMAX (Worldwide Interoperability of Microwave Access) will standardize and promote wireless broadband as a wireless alternative to digital subscriber line (DSL) and cable that can help remove barriers to broadband access by providing last mile connectivity. The standard reduces costs, improves security, throughput and makes the connection more exible and scalable. WiMAX operates using a base station and a subscriber station with the base station controlling access within a cell. WiMAX could als ....etc

Digital Audio's Final Frontier-Class D Amplifier

Digital technology continues its march from media like CDs and DVDs toward your audio speakers. Today, amplifiers based on digital principles are already having a profound effect on equipment efficiency and size. They are also beginning to set the standard for sound quality.

An old idea, the Class D amplifier has taken on new life as equipment manufacturers and consumers redefine the musical experience to be as likely to occur in a car, on a perso ....etc

The interface between different fields is believed to be fertile ground for breakthrough research. The interface between the emerging fields of biotechnology and nanotechnology is particularly interesting. The possibilities for new fruit are diverse: biotechnology offers new approaches for self-assembly of structures at the nanoscale, while nanotechnology offers new methods for probing and accessing biological systems. In this talk, I will discuss research in this new frontier in my group, including 1) self-assembly of 2D nanocomponent arrays ....etc

ABSTRACT
Imagine a supercomputer no bigger than a human cell. Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. Imagine attaining immortality by drinking a medicine. These are just a few products expected from Nanotechnology.
Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed nanoscopic robot arms; Nanotechnology proposes the construction of novel molecular devices possessing extraordin ....etc
