Low-Cost, Entry-Level Mobiles Emerges as Major Market Trend
The evolution of the mobile phone continues at a frenetic and surprising pace. The latest trend is the integration of feature-rich capabilities such as CD-quality music into lower cost mobile phones. Many people in the world like to listen to high-quality music who can't afford or don't want to pay for a higher end device but still want to have a good-sound-quality music player integrated into their phone. Roman Polz from Agere Systems shows in his article in EPN that music is becoming a killer application for such devices.

Magnetic-field probe requires few components
Popularly known as “gauss meters,” various makes and models of magnetic field meters are available on the market at prices that make them unaffordable to most people. This Design Idea by Rama Sarma, EMI-EMC Centre, RCI, Hyderabad, India, combines a commonly available DMM with a single semiconductor component to measure magnetic-flux density and, in turn, magnetic-field intensity.

Ultra Mobile Device Market Will Be Defined By Multiple Forms
The ultra mobile device market, initially defined by the ultra mobile PC, is evolving to become a family of devices that will compose the “ultra mobile device (UMD) paradigm,” reports In-Stat. One ultra mobile device will not be able to meet all of the different UMD usages/applications, the high-tech market research firm says. Three key features differentiate UMDs from products like PDAs and smart phones. First, UMDs must run a full operating system. Second, they must run any application as originally developed and compiled for PCs or notebooks. Third, UMDs must run full web pages unmodified (including flash and java applets) to provide complete Internet experiences.

Optimizing and Testing WLANs, by Tom Alexander
As WLANs (Wireless Local Area Networks) become increasingly common, it’s becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing.
