Intel demos indoor location technology in new Wi-Fi chips at MWC 2015

Intel made several announcements at MWC 2015, including a new chipset for wireless connectivity (Wi-Fi) in mobile devices. This new chipset, the 8270, include in-chip support for indoor location positioning. Below we explain their technology and show a video of it in action. With this announcement, Intel joins Broadcom, Qualcomm and other chip makers in moving broad indoor location positioning into mobile device hardware.

The transition of indoor location positioning into chips is a trend identified in the newest Grizzly Analytics report on Indoor Location Positioning Technologies, released the week before MWC 2015. By moving indoor location positioning from software into hardware, chips such as Intel's enable location positioning to run continuously and universally, without using device CPU, and with less power consumption.

Intel's technology delivers 1-3 meter accuracy, using a technique called multilateration, generating a new location estimate every second. While 1-3 meter accuracy is less accurate than some other technologies that deliver sub-meter accuracy, most systems with sub-meter accuracy require dedicated infrastructure or preparation on a site-by-site basis. Chip-based approaches like Intel's can work universally.

While many applications need sub-meter accuracy, universal and continuous technology can deliver indoor location positioning to a wide range of applications, including social networking, picture geotagging, friend-finding and location-sharing, location-based reminders, emergency call geolocation, and more.

Intel's chip uses standard protocols to access the locations of 802.11mc-compliant Wi-Fi access points in area, and uses 802.11mc's Fine Time Measurement to measure the distances between the device and each access point. Multilateration then gives the device's location, the place that is the specified distances from the various access points.

The video below shows their technology in action, moving around the Intel booth at MWC. It's important to remember that this technology demonstration is based only on Wi-Fi based positioning, and does not incorporate motion sensing or other complementary technologies. Presumably a production-ready system would incorporate sensor fusion motion sensing to deliver an even smoother and more accurate experience. Given that, this demo is even more impressive.

We're looking forward to having chip-based indoor location positioning of this sort in our next smartphones!

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

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
