An ace up Google's sleeve in Bluetooth-based Indoor Positioning?

Everyone's talking these days about Google's new indoor mapping, which they say will track a cellphone's location as a person walks around a mall or airport.  This would obviously be a huge breakthrough, now that everyone's gotten used to using cellphones for navigation and location services, and would naturally like to keep doing so while walking around a mall.

Nokia just counter-attacked with an update on their own indoor navigation research, which uses Bluetooth-based "beacons" to improve indoor positioning.  Of course, this research isn't new, it's a continuation of work at Nokia that dates back several years.  But the new announcement places this new capability in the context of new Windows-based smartphones.

Of course, there are dozens of companies working on indoor positioning.  Grizzly Analytics reported many of these in our report on next-generation location services, and we'll soon have an updated report out on indoor location positioning which analyzes research by Google, Nokia, RIM, Qualcomm, Samsung and many more.

In the meantime, here's a fun fact that nobody has reported in the recent flurry of articles on the race between Nokia and Google to indoor location services:  Who do you think holds a granted U.S. patent on using Bluetooth for indoor positioning?

Google.

A U.S. patent titled Location determination for mobile units was granted back in 2004 to Motorola.  It discussed, in terminology that feels outdated this many years later, using fixed Bluetooth devices with known locations to track mobile devices that are also Bluetooth-equipped.

Yep, that's the same as using beacons to position smartphones.

This patent is presumably soon to be owned by Google, with their acquisition of Motorola Mobility and their huge patent portfolio

Of course, there are many differences between the methods discussed in this patent and Nokia's research.  Motorola's method did the computation in the cloud, while Nokia's looking at location determination on the handset.  And Nokia's looking at more sophisticated algorithms for triangulation and positioning. 

But it's fascinating nonetheless that Nokia's big announcement of Bluetooth-based positioning, that they and everyone thought (with justification) would differentiate them strongly from Google's approach, would step right into the area of a Google-owned patent.

Sensor-fusion indoor location system in over 30 malls in Singapore

SingTel just deployed indoor mapping and navigation from Swedish start-up  SenionLab  in over 30 shopping malls in Singapore, with 20 more in planning, in the biggest single deployment we've seen yet of customized indoor location technology. The most significant aspect of this deployment is that this is one of the first commercial deployments of indoor location technology that uses a new technology approach called "sensor fusion," which uses sensors in smartphones (gyroscope, compass, accelerometer, ...) to track location by sensing the phone's movements. Most indoor location systems determine location by measuring the signals of nearby Wi-Fi hotspots or cellular antennas, but this risks looking choppy as the phone waits for the radio signals to change to detect the next place it is. Sensing motion using phone sensors makes the system work more smoothly, regardless of radio signal details.  (The SenionLab solution does use Wi-Fi signals as well, to compe...

Nokia indoor location positioning research shown at MWC 2012

Grizzly Analytics has been looking closely at indoor location technology, both technology research at major companies and technology solutions available to store-owners and other site managers .  At MWC we expected that indoor location would be prominent, and we weren't disappointed! We had the pleasure of seeing a large number of demonstrations of indoor positioning in action.  This is the first of several blog posts looking at these demonstrations, starting with Nokia. First I'll give some explanation, then below is a video showing Nokia's demo in action and hearing comments from their researchers. Nokia has been researching indoor location technology for years, and the technology has advanced each year but not yet reached market.  Their demo is, in a word, breathtaking, in the speed and precision at which it tracks people walking around the room.  People are seen on a computer screen or phone screen, in real-time, moving as they walk around the demo room flo...

Adding real value to smartphone camera pictures

Most technology features follow a similar path, from imitation to improvement to transformation.  First they imitate something that came before, like telephones imitating the telegraphs of yesteryear.  Then they improve on them, like phones entering individual homes. Then they transform the entire endeavor, completely surpassing the previous technology, like phones automatically connecting people without operator involvement, which enabled society to communicate in ways that telegraph users never contemplated. Cellphone cameras are following a similar path.  At the beginning cellphone cameras were imitating digital cameras, adding the convenience of carrying only one device but basically doing the same as digital cameras did.  Then they improved on them, both with quality improvements and with the ability to share pictures wirelessly without wiring the phone to a computer.  The ability to instantly share and synchronize pictures from a phone is somewhat transf...
