Details:
Throughout the next decade, 802 wireless systems will become an integral part of fourth generation (4G) cellular communication systems, where the convergence of wireless and cellular networks will materialize through support of interworking and seamless roaming across dissimilar wireless and cellular radio access technologies. IEEE 802 Wireless Systems clearly describes the leading systems, covering IEEE 802.11 WLAN, IEEE 802.15 WPAN, IEEE 802.16 WMAN systems’ architecture, standards and protocols (including mesh) with an instructive approach allowing individuals unfamiliar with wireless systems to follow and understand these technologies. Ranging from digital radio transmission fundamentals, duplex, multiplexing and switching to medium access control, radio spectrum regulation, coexistence and spectrum sharing, this book also offers new solutions to broadband multi-hop networking for cellular and ad hoc operation. The book
Gives a comprehensive overview and performance evaluation of IEEE 802.11, 802.15 and 802.16
Includes a tutorial like introduction to the basics of wireless communication
Discusses challenges in mesh/multi-hop relaying networks and provides profound solutions for their realization with 802 Wireless Systems
Covers spectrum sharing on different levels and provides solutions for coexistence, cooperation and interworking of 802 Wireless Systems that are following the same or different standards, but share the same spectrum
Includes a detailed overview and introduction on cognitive radio and dynamic spectrum access
Accompanying website contains simulation software and provides slides of the figures and tables from the book ready for course presentation
This book is an essential text for advanced undergraduate students with a basic working knowledge of wireless communication, graduate students and engineers working in the field of wireless communications.

Broadband PowerLine Communications Technology

PowerLine Communications technology allows the usage of electrical power supply networks for communications purposes and, today, also broadband communication services. The main idea behind PLC is the reduction in operational costs and expenditure for realization of new telecommunications networks. Using electrical supply networks for telecommunications has also been known since the beginning of the twentieth century. Thus high-, medium- and low-voltage supply networks have been used for internal communications of electrical utilities and for the realization of remote measuring and control tasks. PLC is also used in internal electrical installations within buildings and homes (the so-called in-home PLC) for various communications applications. Generally, we can divide PLC systems into two groups: narrowband PLC allowing communications services with relatively low data rates (up to 100 kbps) and ensuring realization of various automation and control applications as well as a few voice channels, and broadband PLC systems allowing data rates beyond 2Mbps and, accordingly, realization of a number of typical telecommunications services in parallel, such as telephony and internet access.

CPU Design Answers to Frequently Asked Questions

Technical books related to CPU design are almost always written by researchers in academia or industry and tend to pick one area, CPU architecture/Bus architecture/ CMOS design that is the area of expertise of the author, and present that in great detail. Such books are of great value to students and practitioners in that area. However, engineers working on CPU design need to develop an understanding of areas outside their own to be effective. CPU design is a multi dimensional problem and one dimensional optimization is often counterproductive.

For instance, as someone who mainly does CPU architecture, I have found that CPU architects who understand how logic design, circuit design and chip integration are really done in practice do a much better job architecting the chip. There are constraints in these different areas that could make an architectural idea hard to implement, and an architect who understands these constraints is more likely to make the right decisions upfront. However, there are really no books out there to help an architect understand quickly how the later stages of chip design work. Reading detailed technical books on physical design to obtain this knowledge is typically not an option given time constraints. The most accessible way today to learn the broader skill set necessary is from chatting with friends and picking up bits of knowledge here and there. Over time the good ones do develop a working knowledge of all areas of CPU design, but it takes many years.
