Collaborators Get A Fix On E-GPS For many OEMs in the wireless-network and mobile-device spaces, Enhanced Global Positioning Systems (E-GPS) are high on the wish list. E-GPS addresses the problem of providing quality timing assistance to GPS-enabled devices in asynchronous networks, such as GSM and W-CDMA. The lack of a common synchronization source means that devices can take longer to provide a location reading. E-GPS brings together two independent positioning... — Lisa Maliniak March 2005 [New Products] A-GPS Receiver ICs Carry Baseband, RF, And Flash Location-based applications are spreading to portable devices that are as diverse as mobile phones, power-constrained smart devices, and compact digital cameras. Designers of such devices want to incorporate real-time location and navigation capabilities without significantly degrading overall power consumption. In the GSC3f and GSC3 SiRFstarIII single-chip GPS devices, designers will find a complete A-GPS digital baseband processor and an RF front end. The GSC3f adds 4 Mb of... — Staff March 2005 [New Products] Embedded Modules Form Powerful RF Engines The ability to exploit higher wireless data-transmission speeds lets OEMs maximize the value of adding wireless connectivity to end products. To that end, Sierra Wireless's dual-band EM5625 embedded module comprises a powerful and reliable wireless engine that can be integrated into a wide range of mobile devices. The module is the first Sierra Wireless product to incorporate Qualcomm's MSM6500 Mobile Station Modem chip set. It therefore provides high-speed, high-capacity wireless data... — Staff January 2005 [Column] Public Safety Overcomes Communication Issues Without question, there is an ongoing and critical need to improve the mobile wireless communications infrastructure that's used by first responders and public-safety agencies across the U.S. In fact, certain problems have acted as key barriers to effective first-responder and public-safety communications and operations. Specifically, these problems include security limitations, communication interoperability challenges, and the availability—or lack thereof—of adequate bandwidth... — Edward Swallow , et al. January 2005 [New Products] Miniature GPS Module Flaunts Very Low Power Between enhanced-911 (e-911) requirements and the rise of location-based services, Global Positioning Systems (GPSs) are becoming more commonplace in mobile devices. To feed this growth, Trimble debuted an ultra-low-power, miniature GPS receiver. The 12-channel Lassen iQ module features two GPS signal-sensitivity modes: Standard and Enhanced. When Enhanced mode is enabled, the module will automatically switch to higher sensitivity if satellite signals are weak. For fast... — Lisa Maliniak December 2004 [News] Bluetooth GPS Navigation System Directs Users Many high-end vehicles come with in-car navigation systems. For those vehicles that aren't equipped with navigation, some companies have come out with impressive aftermarket systems. Instead of buying these systems, however, many consumers would... — Nancy Friedrich November 2004 [News] Single Chip Brings A-GPS To Mobile Phones When the Enhanced 911 (E911) mandate was put into place by the Federal Communications Commission (FCC), both carriers and device makers fought to cost effectively implement a service that seemed to offer little return on investment. Since that time,... — Nancy Friedrich February 2004 [News] Rugged Antenna Outfits Trucks Commercial telematics is a rapidly growing market segment. After all, solutions like asset tracking and data applications are mostly utilized by commercial vehicles. Yet those vehicles come with their own set of needs. For example, they must... — Nancy Friedrich February 2004 [News] Cars Receive Satellite TV A few years ago, a debate raged over whether or not telematics applications would really take off. Now, it's hard to judge where they'll stop. Viewing screens and DVD players are already showing up in a lot of vehicles. One company is even promising... — Nancy Friedrich September 2003 [Cover Story] Location-Based Services Are Positioned For Growth To many people, "location-based services" (LBS) is just one long buzzword. The average American consumer is probably familiar with some of the capabilities of the FCC-mandated e-911 initiative. But he or she has had little real exposure to LBS... — John Blyler September 2003 [News] DoD Prompts GPS Evolution In the past six months, global-positioning-system (GPS) equipment has garnered a lot of media attention over possible threats of enemy jamming. To defense-technology experts, however, this supposed security risk doesn't seem to be a cause for major... — Nancy Konish May 2003 [News] Partners Advance A-GPS The location-services market is expanding quickly. Location-based technologies are finding their way into an increasing number of consumer products. These products, in turn, nurture services like location-sensitive billing and corporate-asset... — Nancy Konish May 2003 [New Products] TCXOs Raise Performance For GPS Receivers A range of Global Positioning System (GPS) Temperature-Compensated Crystal Oscillators (TCXOs) promises to give GPS receivers superior performance. GPS receivers depend upon their local oscillator. They see it as a precise clock that accurately... — Staff April 2003 [News] Handhelds Will Alert Police To Gunshots Despite its economic woes, terrorist worries, and international conflicts, the United States cannot ignore its previously existing problems. An example is the high crime rate. Many of these numerous crimes involve guns. Yet by the time police arrive... — Nancy Konish January/February 2003 [New Products] GPS Positioning Engine Outperforms The Rest > A jointly developed GPS solution has been spawned by Atmel Corp. and u-blox. It claims to require less external parts, while keeping power consumption low. Called Antaris, it targets the high-volume mobile, navigation, and multimedia mass markets.... — Staff November 2002 [News] Hope Rests On Location-Based Services The slow economy has sent carriers and manufacturers on a quest for revenue-bearing services. Meanwhile, the government is ordering compliance with Phase II e-911 requirements, and third-generation (3G) services finally seem to be coming into reach.... — Nancy Konish October 2002 [Product Features] GPS Receiver Attracts New Applications Many third-generation or 3G applications are going to require cellular positioning—both for accuracy and to provide new services. In order for an individual to be directed to the gas station nearest to his or her vehicle, for example, the car's... — Nancy Konish November 2, 2007 [News] SDR Forum Adding Tactical Radio SIG, Moving On Other Initiatives The Software Defined Radio (SDR) Forum is establishing a special interest group (SIG) that will focus on the needs of the worldwide tactical radio community. The Forum, a nonprofit international industry association supporting the advancement of reconfigurable wireless technology, also announced that members will vote on approval of four significant documents at the organization’s general meeting on Nov. 9... — Staff August 6, 2007 [News] National Association of Broadcasters Engineering Handbook - 10th Edition This not-so-little jewel has 2072 pages and weighs 11 lbs. (yes, I actually weighed it). My initial reaction was that I don't have much to do with broadcast standards or technology, but after I read the book I found it was a fabulous reference on electronics, wireless, and communications in general. — Louis E.
