New report on infrastructure-free indoor location positioning Infrastructure-free indoor location positioning technologies offer short term evolution and long term revolution. The short term evolution is the ability to deploy indoor localization in a site without having to install, configure and maintain infrastructure of beacons or locator devices. The longer term revolution is the ability for mass market applications and devices to position themselves universally, in any site worldwide, without any deliberate configuration for each site. This report profiles technologies from eleven companies with infrastructure-free indoor location solutions on the market. We also profile related R&D from Apple, Google, Facebook and others that is not on the market as solutions but may bring universal positioning to mass market reality.

It was an honor to be invited to the Mr Beacon podcast , to discuss indoor location technologies, companies and use-cases. What a wide ranging conversation!

Decawave  announced recently  a $30 Million investment, marking a huge push forward for location-based Internet of Things (IoT) products and solutions. The investment also underscores the growing strength of China in the manufacturing of location-aware electronics. Decawave  is a leading producer of chips and hardware components for ultra-wideband (UWB) radio, which is used for high accuracy localization of devices and tags, mainly in indoor settings. Decawave’s customers use Decawave chips to make a large variety of location-aware electronics. These electronic devices and appliances, including robots, drones, robotic cameras, shopping carts and more, use Decawave’s chips to measure their own locations as they move around indoor sites where GPS signals are not available. Of the  roughly 200 companies in the indoor location market , very few are selling localization technology in chip form that can be incorporated into electronic appliances. Most of the indoor location market is

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: Fin

Every iPhone release is followed quickly by a rage of articles by iFans who are sure it will be the best thing ever and iCynics who disagree. The number of articles by fans of other devices or device-makers pales by comparison. So I decided to write an article on why I'm excited by the just-announced OnePlus Five . I rarely buy a new device before my old one dies. Not that I don't want to - I've seen all the new models at the Mobile World Congress most years, and love gadgets, but I rarely find it worth jumping to a new device, reinstalling all my apps and getting it just as I like it, just for minor improvements that don't change my experience much. So why do I want the OnePlus Five when my current OnePlus Two works perfectly well? In honor of the OnePlus Five, I'm giving five reasons. Reason one: RAM rules I bought the OnePlus Two because it had 4gig of RAM when none of the other top phones did. In fact, it took the market leaders over a year to catch up.

The second Indoor Location Testbed, run by Grizzly Analytics at  GeoIot World 2017 , confirms for the second year that indoor location solutions are beating the previously established industry norms in all metrics of performance. Solutions evaluated this year achieved below 2 meter accuracy, in smartphone and in tag tracking, both with BLE beacons and infrastructure-free. Solutions deployed in under one hour setup. Solutions detected floor changes and maintained positioning accuracy while moving on stairs. Solutions achieved fast first location fixes within seconds of starting. All of these were evaluated and confirmed by our testbed staff, as detailed in this report. The 2017 testbed evaluated five solutions : One based on BLE tags, four on smartphones. One smartphone solution runs infrastructure-free, one incorporates camera-based image processing, and two blend BLE beacons with motion sensing. This Indoor Location Testbed is the only such testbed to evaluate a wide range of m
