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 …

Seeing Quuppa's indoor location technology at MWC 2015

I first met Fabio and Kimmo from Quuppa in 2012, before Quuppa existed, when they had spent years researching indoor location positioning technologies at Nokia Research Center. Less than a year after that they formed Quuppa, independent of Nokia, to bring their technology to market. At the time I called Quuppa "the newest and oldest in indoor location positioning."

Fast forward two and a half years. Their technology has reached market, it can now track both smartphones and BLE devices, and it's accurate to within 20-50cm. Before reading more about their technology, take a look at a video of their demo in action:



Grizzly Analytics has analyzed indoor location technologies by over 150 companies, and virtually all of the radio-based technologies operate by measuring the distance between the device being tracked and other radio devices, and using these distance measurements for either multilateration or fingerprinting. For example, the well known BLE beacons measure a device…

Robot Camera Foreshadows an Era of Location-Aware Electronics

A French company called Move 'N See produces a line of camera robots. Their devices act as a smart tripod, holding a video camera and automatically moving and zooming the camera as people of interest move around a site.

The idea is simple but amazingly innovative. Photo selfies are easy to take, but video selfies are next to impossible. How can I video myself playing football or doing gymnastics, without setting the camera so far back as to be useless? Do spectators want to spend an entire sporting event carefully videoing their friend or relative moving around the field?
Enter Move 'N See's "personal robot cameramen." Their devices aim, pan and zoom a video camera as one or more people move around an area. The people of interest wear armbands whose locations are tracked, enabling the camera controller to know where to aim the camera. The camera controller also includes enough smarts to adjust the camera smoothly and to capture multiple people evenly. The armband…
