Short indoor location video from DecaWave chip launch

Grizzly Analytics was happy to be invited to the product launch of DecaWave's new chip for indoor location positioning in early November. Their chip uses UWB radio to precisely measure the distance between two chips. If their chips are put inside "beacon" devices in a room, and also inside "tags" on objects that move around the room, a system can track the locations of the objects moving around the room very precisely, to within 12-15cm.

We were unable to video a complete large-scale demo, because of the big crowd in the room, but we did get the following video that shows how precisely the system is able to track objects as they move around. The demo was done with four beacons in the corners of the room that are used to triangulate the locations of chips moving around the room. The demo as shown does not do any smoothing or post-processing of that triangulation.

DecaWave's chip is the latest in more than 50 solutions coming to market for indoor location positioning, using a wide variety of approaches. DecaWave's technology cannot be used on mobile devices until their chips are incorporated into those devices. But for industrial applications, and in the future if their chips are incorporated into mass-market devices, the precision that they offer is stunning.

Another company offering very high accuracy positioning is Quuppa (click here for a description and video).  Several others, including BeSpoon, are in the works. Most other indoor location solutions are less accurate, estimating locations within 5-8 meters, but have the obvious advantage of running on today's smartphones.

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 …

33 Indoor Location Technologies at Mobile World Congress 2017

The number of companies exhibiting indoor location technologies at the 2017 Mobile World Congress (MWC) skyrocketed to 33!

Before MWC started, we released our Guide to Indoor Location at MWC, with 23 companies:

During the conference we notified our guide recipients of 10 other indoor location exhibitors that we saw. (Sign up here to receive our guide and to be on our mailing list for next year's MWC.)

This is many more indoor location related exhibits that previous years. The area is growing by leaps and bounds! Our recent report on indoor location technologies analyzed and profiled almost 200 companies!

Here are some videos, so you can see the technologies in action, followed by a list of the other indoor location companies that were at MWC.

First up is Philips Lighting, with high-accuracy indoor location positioning based on LED light modulation and visible light communication (VLC) technology:

Next comes Estimote, makers of Bluetooth (BLE) beacons, who introduced self-mapping b…

See great indoor location tech from the 2017 testbed

The videos from the Indoor Location Testbed at GeoIoT World 2017 are now released! Here is your chance to see how these solutions performed in our real-world evaluation, in the videos below. The testbed evaluated each solution by walking around a real-world venue, the GeoIoT World 2017 conference, measuring performance at 10 pre-selected points.

Click here for the testbed report, which analyzes each solution's performance in a wide variety of metrics, including real-time accuracy, accuracy stabilization, consistency, latency, floor change, first fix, setup time & more.

Let's start with BlooLoc's tag-based solution, which achieved accuracy under 2m in real-time and under 1.5m after stabilization:

Then let's look at the infrastructure-free solution from GipsTech, which achieved accuracy under 2m without using any beacons or radio signals:

Next is GipsTech's solution with BLE added:

Next is BlooLoc's phone-based solution:

Finally, we see Accuware's solution…
