Expert on Stealth Technology releases new book
Finite Antenna Arrays and FSS
Ben A. Munk
John Wiley & Sons, $150
This book is a resource for engineers, students and researchers and discusses finite antenna arrays and how to minimize the radar cross section of these arrays. Frequency selective surfaces (FSSs) have important military and civilian applications including antenna theory, satellite communications and stealth technology. Ben Munk is an authority on the subject, having been instrumental in the development of stealth technology for the U.S. Air Force.
Multiantenna Transceiver
Techniques for 3G and Beyond
Ari Hottinen, Risto Wichman, Olav Tirkkonen
This book presents the basic concepts behind modulation design for multi-input multi-output (MIMO) wireless channels, and develops multi-antenna transceiver techniques from the signal processing perspective. The Finnish authors describe linear processing transmit diversity methods that operate with or without channel state information at the transmitter, then provide examples of high throughput, low complexity matrix modulation schemes when signaling without side information. The final section addresses closed-loop methods, and constructs hybrid schemes where the amount of overhead due to feedback is reduced by combining open-loop transmission with closed-loop signaling.
802.11 Security
By Bruce Potter and Bob Fleck
O’Reilly, $34.95
Wireless networks are fraught with security challenges for users and network administrators alike. The lack of physical security, access to free auditing tools that double as attack tools, and the ability to monitor traffic without being noticed make wireless networks an easy target for malicious users. In O’Reilly’s 802.11 Security, authors Bruce Potter and Bob Fleck tackle the issues unique to wireless networking, covering the areas of risk and potential attack and the tools that can be used to successfully defend against them. Starting with the fundamentals, the book discusses the challenges of Wireless Access Points (WAP), bandwidth stealing, and the problematic Wired Equivalent Privacy component of 802.11.
Learning Wireless Java
Qusay H. Mahmoud
O’Reilly, $34.95
Now that the Java programming language has come to the wireless arena with the advent of the Java 2 Platform, Micro Edition (J2ME) from Sun Microsystems, the possibilities for new wireless applications and over-the-air distribution models for handheld devices are beckoning to Java programmers. Learning Wireless Java by Qusay H. Mahmoud was written to bring these programmers up to speed with wireless Java as quickly as possible. Mahmoud, who has written dozens of articles and tutorials on developing wireless applications, contends that the next big shakeup in the technology industry is wireless, and wireless Java will play an important role in it. According to Mahmoud, there are numerous advantages to using Java for wireless devices, including the dynamic download of applications that will run even when the device (say, a cell phone) is disconnected from the wireless network or out of the coverage area. A second advantage is that wireless Java provides support for disconnected operations. And, true to Java in general, wireless Java applications are platform-independent: they run on all wireless Java-enabled devices in the same manner.
