RF Technologies for Low Power Wireless Communications
The driving purpose of recent advances in communications technology has been to untether users, allowing them complete mobility and freedom of movement while maintaining their connection to electronic services. The wireless revolution has led to an expectation that voice, fax, and data services, and even internet access, can be available anywhere, without recourse to specific locations in a fixed infrastructure and even while moving or...

RF CMOS Power Amplifiers: Theory, Design and Implementation
The convergence of home electronics, computer, and communication technologies is one of the most exciting technological and business trends of the next decades. The key to a wireless solution is the building of intelligent units, that can communicate clearly in a wire-free environment, occupy as little space as possible, and consume low power to maximize battery life. All these criteria are best met by highly integrated, low power, battery...

Propagation Handbook for Wireless Communication System Design
Wireless means different things to different people. For this book, it refers to the radio systems that provide point-to-point, point-to-multipoint, and Earth-space communications over transmission links that propagate outside buildings through the lower atmosphere. Wireless systems are being built that provide data transmission between computers and other devices on one’s own desk. These are part of the wireless world but not the part...

Phase-locked loops for wireless communications Digital, Analog and Optical Implementations
This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for developing the text was to present a complete tutorial of phase-locked loops with a consistent notation. I believe this is critical for the practicing engineer who uses the text as a self-study guide. Three years after the first printing, I discovered there was a need for a second edition. I had taught several short courses from the text, and...

Performance modeling and analysis of bluetooth networks
Bluetooth is a recent wireless communication technology specifically intended for short range ad hoc networking. It was initially envisaged as a simple cable replacement technology to connect various mobile, portable, and fixed devices such as PDAs, mobile phones, laptops, and printers, but its use has soon spread to include various general purpose networking tasks, and a number of Bluetooth-enabled devices have appeared on the market. In...

Whereas today’s expensive wireless infrastructure depends on centrally deployed hub-andspoke networks, mobile ad hoc networks consist of devices that are autonomously selforganizing in networks. In ad hoc networks, the devices themselves are the network, and this allows seamless communication, at low cost, in a self-organized fashion and with easy deployment. The large degree of freedom and the self-organizing capabilities make mobile ad hoc...

Microstrip Filters for RF/Microwave Applications
Filters play important roles in many RF/microwave applications. Emerging applications such as wireless communications continue to challenge RF/microwave filters with ever more stringent requirements—higher performance, smaller size, lighter weight, and lower cost. The recent advances in novel materials and fabrication technologies, including high-temperature superconductors (HTS), low-temperature cofired ceramics (LTCC), monolithic...

Implementing 802.11, 802.16, and 802.20 Wireless Networks
Communication, a word that many associate with modern technology, actually has nothing to do with technology. At its core, communication involves nothing more than the spoken or written word, and symbolic languages like art and music. Technology has become synonymous with communication because technology has historically been the method by which communication to or by the general population takes place. From the printing press to the...

Hardening IEEE 802.11 wireless networks
IEEE 802.11 is a Wireless Local Area Network (WLAN) standard which specifies a radio interface and Layer 2 (Link Layer) protocol for data communications in the 2.4 Ghz spectrum. 802.11b supports up to 11 Mbps of capacity, depending on what part of the world you are in, and has a range of up to a hundred meters or more in open spaces, but more like 50 Meters in a practical office environment using off the shelf equipment. 802.11b is not just...

Handbook of Wireless Networks and Mobile Computing
The past five decades have witnessed startling advances in computing and communication technologies that were stimulated by the availability of faster, more reliable, and cheaper electronic components. The design of smaller and more powerful devices enabled their mobility, which is rapidly changing the way we compute and communicate. For instance, the worldwide number of cellular phone subscribers has quadrupled in the last five years and has...

Digital signal processors in cellular radio communications
Current trents suggest that the wireless communications industry will continue to grow at an impressive rate. Today, the dominant application of wireless technologies is speech communications. A number of cordless, cellular, and personal communications services (PCS)standards have been developed and at least half a dozen of them are successful such as global system for mobile communications (GSM), IS-136, IS-95, PDC, Digital European...
