PLACE Conference London and Qualcomm's LED-Based Location Technology

It was great attending and presenting at the PLACE London conference last week on November 17. Many technology vendors in the indoor location space, mostly start-ups but larger companies as well, were in attendance, and many large retail companies were there as well. It was the perfect audience to discuss indoor location technology and its impact on retail.

My panel on sensor technologies included representatives from CSR (recently acquired by Qualcomm), Meridian (a subsidiary of Aruba networks) and Pole Star, all companies bringing indoor location technology to market. Other companies presenting at the conference included IndoorAtlas, Qualcomm, Aisle411, LocalSocial, RetailNext, ShopperTrak and Indoorz. Big thanks go to the team from Opus Research for a great job in organizing the conference.

Of course, these dozen companies are only a few of the more than 100 companies in the indoor location area. But it was a great cross-sample of the market.

Several companies were talking about their SLAM-related technology, which enables indoor location technology to work in a new site without extensive customization. Grizzly Analytics has identified SLAM technology as one of the big new technologies that's poised to revolutionize indoor location systems.

One of the surprises, for me, was seeing a demo of a great technology from Qualcomm Technologies (QTI), which does indoor location positioning based on special LED lights. In their system, the LED lights use modulation to send signals that identify each light bulb and its location. Phones that sense the light, using their cameras, can combine (multilaterate) the signals from multiple nearby lights to determine where they are.

We've written before about indoor location systems based on modulated light. A start-up called ByteLight is bringing related technology to market, and a start-up called i2Cat is doing similar things using a phone's ambient light sensor. And others are working on lighting with built in wireless technology, that can also do location positioning. But Qualcomm has a great looking product, with fast and precise positioning, succeeding particularly well at combining the signals from multiple lights to get a very precise location fix. And Qualcomm has the corporate muscle to bring it to market.

Qualcomm reports that their system can track a phone's location to within 10cm in 3D. This puts Qualcomm's technology in an elite group of systems that delivers sub-meter indoor location accuracy, as well as being one of only a few technologies that is accurate in the 3rd dimension (height) as well.

Of course, the infrastructure cost of installing custom lighting is higher than that of BLE beacons. And using the phone's camera to track location will use more battery than many other approaches. But Qualcomm says they're solving the battery problem by intelligently turning their tracking system off and on. They are currently bringing this technology to market in partnership with Accuity Brands lighting, who already delivers lighting to many large retailers. For sites wanting high accuracy that works on a wide variety of smartphones, Accuity's product based on Qualcomm's technology is a very strong contender.

Of course, Qualcomm's technology was only one of a dozen discussed at the PLACE Conference, and each technology has its benefits and tradeoffs. If you're interested in staying on top of indoor location, you should definitely attend a future PLACE Conference. And see the Grizzly Analytics reports on sub-meter accuracy indoor location and on self-learning SLAM technologies to learn about more cutting edge technologies.

Finding indoor location tech, and fans, at MWC 2017

Over 100,000 people are now planning to attend the 2017 Mobile World Congress in Barcelona, in February. Many will flock to the newest devices, many to the keynote speeches from market leaders, and many to the latest tech from a huge variety of exhibitors. But how does anyone find all the tech they want to see? Anyone who has been to MWC in the past will tell you that there is no way to be sure you're seeing all that you want to see. Anyone interested in indoor location technology now has a solution. The Grizzly Analytics Guide to Indoor Location Technology at MWC2017 will list all the companies at MWC that are demonstrating, presenting or talking about indoor location tech. (Obviously we may miss one, but since we've reported on indoor location tech from over 200 companies , we expect to be fairly comprehensive.) The guide will be organized by technology type and also by MWC hall number, so you can plan your time accordingly. If you are exhibiting i...

The year indoor location will truly take off

For years I've been writing sentences like "this will be the year that indoor location will explode into the market." I, and many others, have been expecting indoor location technology to enable the huge range of location-enabled apps, which currently work only outside where GPS signals are available, to work inside. But until now the promise of indoor location has remained a promise. But if we look at the reasons for this, we'll see that it is about to change. 2017 and 2018 are poised to be the years that the challenges keeping indoor location from going mainstream will be solved. First is accuracy. Most indoor location technologies until a year or so ago had accuracy in the range of 4 to 8 meters. This sounds good in principle, and in fact is better than GPS in many cases. But GPS systems are able to use road details to hide their inaccuracies, so that the blue dot seems to follow your driving car almost perfectly. But indoors, this sort of inaccuracy means y...

Indoor Location, GeoFencing and Retail (Updated w/ video)

We've written a lot about indoor location technology , which is bringing location services indoors where GPS doesn't work. And we've written more recently about GeoFencing , a new location technology that enables smartphones to display content or take other actions when entering a specified area. And a few weeks ago we wrote about a company that was bringing the two together . Now Aisle411 has entered the ring, adding GeoFencing to their indoor solution . And they're bringing GeoFencing to life in the retail store industry . Aisle411's solution lets you navigate your way around a store to find specific products on the shelves. You can even enter your whole shopping list, or the items you need for a recipe, and the app will guide you around the store to buy everything you need quickly.   And here's where the GeoFencing comes in:  As you near certain products, you'll get offers for related products on your smartphone screen. They might be as s...
