Location Based Services on GPS Handsets

In the wake of personal navigation devices success, cellular carriers have started to offer on-board and off-board navigation solutions, as well as a range of Location Based Services (LBS) such as friend finder and local search on GPS handsets.

Community and social-networking-related functionality, such as the sharing of POIs (Points of Interest) and geo-tagged pictures, is also becoming popular and is expected to boost GPS-enabled handset uptake as carriers, handsets manufacturers, and service providers look to capitalize on the LBS trend.

While most CDMA handsets are already GPS-enabled and GPS is set to become a standard feature in GSM smartphones, GSM feature phones are next on the agenda to be equipped with GPS technology," says ABI Research principal analyst Dominique Bonte. "GPS chipset vendors increasingly target handsets, looking for new markets and spurred on by the recent dramatic growth of personal navigation devices."

However, as GPS begins to penetrate lower-end phones, the cost, power consumption, and footprint of GPS chipsets will have to be further reduced. This will be made possible by single chipset technology and the emergence in 2009 of combination chips integrating GPS, Bluetooth, and Wi-Fi all on one die.

Major silicon vendors such as Broadcom, NXP, and Atheros are well positioned to develop such solutions following the acquisition of GPS chipset vendors Global Locate, GloNav, and u-Nav, respectively.

At the same time, the thorny issue of indoor GPS coverage has to be addressed, since handset-based LBS services are frequently used in challenging environments with reduced GPS signal strength.

Network-assisted A-GPS and high-sensitivity GPS-receivers are becoming key requirements to reduce the time necessary to acquire fixes and to improve location accuracy.

Digital Grids Reshape the Future of Electricity

What was once a simple, unidirectional flow of electricity from centralized power plants to passive consumers is evolving into a complex, intelligent network where millions of distributed resources actively participate in grid operations. This transformation, powered by smart grid technologies, represents one of the most significant infrastructure shifts of our time. It promises to reshape how we generate, distribute, and consume energy. At its core, the smart grid represents far more than mere digitization of existing infrastructure.  This bi-directional capability is fundamental to understanding why smart grids are becoming the backbone of modern energy systems, facilitating everything from real-time demand response to the integration of renewable energy sources. Smart Grid Market Development By 2030, smart grid technologies are projected to cover nearly half of the global electrical grid, up dramatically from just 24 percent in 2025. This expansion is underpinned by explosive gr...
