In this first ever published study of life inside Indonesian schools, this book uniquely explores the role that classroom teachers play in school reform efforts. Weaving together narrative description and critical analysis, Christopher Bjork highlights the complexities of teachers' behaviour and locates their actions within the broader cultures of education and government in Indonesia. He also focuses on the Indonesian government's recent attempts to delegate increased power to classroom teachers. The decision to decentralize represented a significant departure from previous education policies. For the first time teachers were asked to perform as leaders rather than followers in their schools. Most educators resisted these opportunities to increase their influence, opting instead to conform to the status quo. Analyzing this lack of action, the book connects the stasis to deeply engrained views about the role of the Indonesian teacher within the schools, the society, and the state.

Because they provide practical machine-to-machine communication at a very low cost, the popularity of wireless sensor networks is expected to skyrocket in the next few years, duplicating the recent explosion of wireless LANs.

Wireless Sensor Networks: Architectures and Protocols describes how to build these networks, from the layers of the communication protocol through the design of network nodes. This overview summarizes the multiple applications of wireless sensor networks, then discusses network device design and the requirements that foster the successful performance of these applications.

The book discusses factors affecting network design, including the partitioning of node functions into integrated circuits, low power system design, power sources, and the interaction between antenna selection and product design. It presents design techniques that improve electromagnetic compatibility and reduce damage from electrostatic discharge.

The text also describes the design features of the wireless devices themselves, presenting a thorough analysis of the technology that engineers and students need to design and build the many future applications that will incorporate wireless sensor networks.

Although it is one of the oldest sectors of electronics and now somewhat taken for granted, radio frequency transmission literally changed our world. Today, it is still the backbone of myriad applications, from broadcasting to electronic counter-measures. The wide variety of hardware in use means that those working in the field must be familiar with a multitude of principles and applications, but finding an up-to-date, comprehensive source for this background material has been difficult, if not impossible.

The RF Transmission Systems Handbook addresses the underlying concepts, operation, and maintenance of high-power RF devices, transmission lines, and antennas for broadcast, scientific, and industrial use. Focusing on devices and systems that produce more than one kilowatt of output power, the handbook explores the following major topics:

Applications: The common uses of radio frequency energy
Fundamental principles: The basic technologies, concepts, and techniques used in RF transmission
Power vacuum devices: The principles and applications of gridded vacuum tubes and microwave power devices
Solid-state power devices: The operating parameters of semiconductor-based power devices
RF components and transmission lines: The operation of hardware used to combine and conduct RF power
Antenna systems: The different types of antennas and their basic operating parameters
Troubleshooting: Basic troubleshooting techniques and the operation of important test instruments

Contrary to the perceptions of many, RF technology remains a dynamic field that continues to advance to higher power levels and higher frequencies. Those who specify, install, and maintain RF equipment will welcome this reference that uniquely serves their needs.

CMOS technology has now reached a state of evolution, in terms of both frequency and noise, where it is becoming a serious contender for radio frequency (RF) applications in the GHz range. Cutoff frequencies of about 50 GHz have been reported for 0.18 m CMOS technology, and are expected to reach about 100 GHz when the feature size shrinks to 100 nm within a few years. This translates into CMOS circuit operating frequencies well into the GHz range, which covers the frequency range of many of today's popular wireless products, such as cell phones, GPS (Global Positioning System) and Bluetooth. Of course, the great interest in RF CMOS comes from the obvious advantages of CMOS technology in terms of production cost, high-level integration, and the ability to combine digital, analog and RF circuits on the same chip. This book discusses many of the challenges facing the CMOS RF circuit designer in terms of device modeling and characterization, which are crucial issues in circuit simulation and design.

This handbook is intended to give the broadcast industry an authoritative guide to the Radio Data System (RDS), also called Radio Broadcast Data System (RBDS). Since the standard's adoption, about 700 stations have begun broadcasting RDS in the United States. There is a wide variety of encoding equipment with prices starting as low as $400, and over 30 models of RDS receivers have been introduced for
cars, home receivers, portable and even PC receivers. Automobile manufacturer's such as General Motors, Ford, Audi, and Porsch now offer RDS on new vehicles. Yet despite all the support equipment in place, the FM broadcaster has been reluctant to implement and utilize this service, mainly because of a lack of understanding of what RDS can do for the station.
This book finally provides the information required to understand RDS and its possibilities on a variety of levels, so that everyone involved in radio can make the most of it. Station owner, program director, salesperson, and talent alike will find the information he or she requires to maximize the possibilities of this new technology.
Each feature of the system is explained in terms of its practical implementation at the station, and interviews with broadcasters currently using the system add a hands-on perspective.
Scott Wright is a recognized pioneer in RDS development. As the
designer of Delco Electronics' first RDS receiver, he has been
extremely active in the development of the RDS standard in the US and
in efforts to educate the broadcast community about its potential. He
has represented Delco at the European Broadcasting Union's (EBU) RDS
Forum and is currently the Chairman of theNational Radio Systems
Committee RBDS Subcommittee, the US standard-setting body. He is also
a member of the Electronics Industries Association's (EIA) RDS Forum.

The revolution of wireless communications has only just begun to transform the telecommunications industry worldwide. This book offers insight into the possible options for corporate strategists and government policymakers as they look to harness the expansion of wireless communications to meet the goals of sustainable telecommunications development. Using a multidisciplinary approach which combines policy research, legal analysis, business economics, and models of sustainability from the environmental sciences, the book compares the development of wireless communications in four countries: the United States, the United Kingdom, Russia, and Brazil.
The comparative analysis points to common themes and opportunities, including:
* breaking down the barriers between wireless and wireline access by changing the regulatory design which constrains service providers;
* targeting the development potential of wireless access through the utilization of new technologies and service models; and
* using wireless access as the basis for full facilities-based competition in both developing and developed world markets.
No other book today offers this broad a context for a discussion of wireless communications and its potential impact on the evolution of the telecommunications industry.

This volumes discusses various aspects regarding the capacity/achievable data rate of stationary Rayleigh fading channels. First, it analyses bounds on the achievable data rate with zero-mean proper Gaussian input symbols, which are capacity achieving in the coherent case, i.e., in case of perfect channel knowledge at the receiver. These bounds are tight in the sense that the difference between the upper and the lower bound is bounded for all SNRs. The lower bound converges to the coherent capacity for asymptotically small channel dynamics. Furthermore, these bounds are extended to the case of multiple-input multiple-output (MIMO) channels and to the case of frequency selective channels. In a further part, the present work studies the achievable rate with receivers based on synchronized detection and a code-aided channel estimation. For a specific type of such a receiver an approximate upper bound on the achievable rate is derived. The comparison of this approximate upper bound and the achievable data rate with receivers using synchronized detection based on a solely pilot based channel estimation gives an approximate upper bound on the possible gain by using this kind of code-aided channel estimation in comparison to the conventional receiver using a solely pilot based channel estimation. In addition, the achievable data rate with an optimal joint processing of pilot and data symbols is studied and a lower bound on the achievable rate for this case is derived. In this context, it is also shown which part of the mutual information of the transmitter and the receiver is discarded when using the conventional receiver with synchronized detection based on a solely pilot based channel estimation.
