A range of solutions are vying to replicate what GPS does outdoors in an indoor environment, from Wi-Fi to Bluetooth to “terrestrial” GPS, plus many others. Which one is likely to be successful? IMS Research (recently acquired by IHS Inc.) said the answer will not simply be just “one.” Locating a smartphone in an outdoors environment is straightforward, with more than 90 percent of smartphones providing GPS functionality. However, GPS becomes less useful in built-up areas and can be useless indoors, reports IMS Research.
Because LBS Insider’s deadline is this week, CTIA coverage from New Orleans is not included in this month’s column. Janice Partyka, editor of GPS World’s Wireless Pulse, is covering CTIA in the Crescent City for the latest location-based services, M2M, and connected vehicle news. So instead of talking about CTIA (and why there aren’t many pure LBS players or sessions there anymore), this column examines the hype surrounding indoor positioning — is it LBS’ savior, or just another technology that may, or may not, pan out?
At the Mobile World Congress in Barcelona, Spain a few weeks ago, a company called Loctronix introduced meter-level indoor positioning technology. “In […]
Broadcom Corporation, maker of semiconductor solutions for wired and wireless communications, has introduced a new location architecture to provide more responsive outdoor and indoor positioning capabilities for smartphone devices. With proven third-generation multi-constellation support and tight integration with sensor components and Broadcom’s connectivity sub-system, the new solution opens the door to innovative applications, such as indoor positioning and place-based mobile commerce, Broadcom said.
Mobility’s first phase saw fixed-line communications go mobile. The next phase saw the Internet go mobile. We now behold a paradigm shift in the third phase, where real world communication bridges to the virtual world, via richer communications on smartphones. For device manufacturers and location-aware service and app creators, it’s no longer about creating unique standalone experiences, it’s about enhancing real-time experiences by enriching everyday consumer behavior with virtual content and relevant information to a particular place and point in time.
Indoor location technology is evolving; indoor mapping is coming along and apps that seamlessly work in and out […]
Cell-phone users are often more concerned about the speed of positioning than the accuracy, making time-to-first-fix the most important factor in a GNSS mass-market receiver’s perceived performance. However, TTFF is generally difficult to characterize and optimize because of the need to encompass a wide range of environments, including indoors.
