Cambridge Consultants Unveils Indoor Locator System

March 7, 2013By
Tracking_O

New technology from product development firm Cambridge Consultants can accurately detect someone’s location indoors when GPS drops out. A number of sensors and a custom algorithm determine the location, with an accuracy of within approximately 1 percent of the distance traveled. The technology uses low-power, low-cost sensors and the device concept is small enough to clip on a belt. It... read more

Will Fragmentation Hurt Location Business?

December 12, 2012By

Get out of the way, GPS. Wi-Fi is elbowing in on the location game. Wi-Fi operators are tracking people and offering retailers and marketers access to customers’ behavior and location. Traffic patterns emitted by smartphone Wi-Fi signals let network operators keep tabs on what shoppers are doing. Heat maps are being created with data from Wi-Fi points to map out... read more

A Look at Small Indoor Location Competitors

July 18, 2012By

Everyone wants a piece of the pie, the upcoming indoor location pie. Big companies and start-ups are engaged, some in research, others having launched solutions. While Wi-Fi is the most common technology, many companies are pursuing alternate methods, including GPS, audio, Bluetooth, small cell/cellular, distributed antenna systems (DAS), near field communication (NFC), white band, sensors, movement tracking, beacons, and more. Of the large players who are making a play for the indoor market, Cisco, Google, Microsoft, Motorola, Nokia, Qualcomm, RIM, and TCS are the furthest along, reports Grizzly Analytics. read more

Expert Advice: Getting to Accurate Everywhere Location

February 1, 2012By

In the next two to four years, mobile device location platforms will be able to provide positioning performance that enables emergency call (E911) and location-based services (LBS) with excellent accuracy (5–10 meters) in all locations. We call this accurate everywhere location, and it will be a significant enabler of indoor navigation applications and for even wider adoption of consumer LBS. In fact, we may eventually forget how we ever lived without it. This technology can enhance our lives by enabling our mobile devices to know precisely where we are at all times. Armed with this information, our devices can behave in a way that suits our specific situation, and they can do this without us having to do anything other than keep the phone with us. read more

Expert Advice: Exploring the Technologies Behind Location-Gate

September 1, 2011By

For the past several months, controversy has raged over the revelation that Apple and Google tracked mobile subscriber location movements and stored that information in an unencrypted file on the handset, where it was potentially vulnerable to hacking and other inappropriate usage. The resulting Location-gate scandal highlights the sometimes tenuous control of mobile subscriber information versus the business objectives of dominant platform and applications providers. These business objectives may include immediate revenue opportunities from the subscriber being tracked or broader self-interest initiatives, such as collecting marketing data that may be valuable to third parties like advertisers, or building subscriber-reported Wi-Fi access point databases. read more

Down and Deep

December 1, 2010By
Figure 1. In Shinjuku, Japan, a receiver tracks nine GPS satellites, but only three (white lines) with direct line of sight, giving an HDOP of 58. Add two QZSS satellites (green) for an HDOP of 3.

As we all know, GPS is practically perfect in every way — as long as it’s outside and unobstructed. Even cell phones can now produce meter-level accuracy under open sky. There are still many deficiencies in state-of-the-art location, particularly in deep urban canyons and inside large buildings. Which technologies will lead personal navigation into the future? read more
