The ultimate winners appear to be the Internet and software players. The key to success remains content and the software that delivers it.

Cingular Wireless has launched its first generally available, location-based service with TeleNav Inc's GPS Navigator. Cingular business and government customers can get turn-by-turn voice and onscreen GPS directions, while driving or walking, on Cingular business devices.

To Locate a Phone or PDA GNSS/UMTS Prototype for Mass-Market Applications Jan 1, 2006 By: GÜnther Heinrichs, Jinkel, Christian Drewes, Linus Maurer, Andreas Springer, Rainer Stuhlberger, Christian Wicpalek

An important step for Galileo will be availability of hybrid Galileo/GPS receivers in combination with wireless communications network positioning capabilities for consumer applications. This article presents ideas regarding an integrated GNSS/UMTS receiver architecture to meet the needs of seamless indoor/outdoor navigation.

Getting into Pockets and Purses Antenna Counters Sensitivity Loss in Consumer Devices Nov 1, 2005 By: Brad Hurte, Oliver Leisten

Add one more to the list of challenges faced by consumer GPS-enabled devices: the human hand that holds them. Body loading significantly degrades receiver sensitivity. A dielectrically loaded quadrifilar helix antenna can ameliorate this condition.

“We were having success with this technology before, but now we have all these major players launching LBS, indicative of a momentum we’ve never seen before.”
