Broadcom delivers on-chip GeoFencing and indoor positioning

We've talked a lot about GeoFencing recently.  GeoFencing is the technology behind location-based reminders and location-based promotions, but more importantly, it transforms mobile apps to being proactive based on location, instead of acting only when invoked by users. GeoFencing is being researched and developed for indoor location applications, mobile app discovery, and more.

But GeoFencing brings technical challenges.  Constantly monitoring a phone's location to see when it enters or leaves a GeoFence drains the CPU and the battery.  Checking only every minute risks not catching a GeoFence crossing in time.  Additionally, GeoFencing needs to integrate GPS, indoor location systems, and other location positioning methods, depending on the phone's location and capabilities.

To answer these challenges, Broadcom has just released a GNSS chip (supporting GPS and other location systems) that includes built-in hardware-based GeoFencing.  Their aim is to support GeoFencing without battery drain, with the hard work being done by the chip, not software.

We predicted in our comprehensive GeoFencing report that GeoFencing support would move to chips, and reported there on GeoFencing research by Qualcomm and other chip makers. With their new chip, Broadcom has staked a claim in this huge new area.  Their chip integrates GeoFencing with not only GPS, but also Bluetooth Low Energy (BLE), Wi-Fi, sensor fusion, Near Field Communication (NFC) and other location positioning approaches.

Broadcom says that they will be showing their location innovations at MWC next week.

For more on GeoFencing, see our comprehensive report on ongoing R&D in the area, which enables you to learn about developments before they reach market.  Also of interest is our comprehensive report on indoor location positioning technologies.

33 Indoor Location Related Start-up Acquisitions

  Acquisitions Continue in the Indoor Location Industry; Grizzly Analytics Shows Price Growth at the High End and Continuity at the Low End New York, NY, February 22, 2021 - Despite the recent pandemic, M&A deals in the indoor location area have maintained a steady pace of 4-5 deals a year. At the high end of the spectrum, prices have increased to up to $400 Million for the highest priced recent deal and $165 Million for the second highest. At the lower end, many earlier stage companies have been acquired in the $2-3 Million range. A newly updated report from Grizzly Analytics gives prices and strategic details for 33 acquisitions in the indoor location area.  While the highest priced indoor location acquisitions have historically involved chip-based technologies, recent acquisitions have been more varied. “A few years ago the focus of indoor location M&A was all around pure localization technologies. The biggest deal to date is in fact for a chip-based localization ...

Adding real value to smartphone camera pictures

Most technology features follow a similar path, from imitation to improvement to transformation.  First they imitate something that came before, like telephones imitating the telegraphs of yesteryear.  Then they improve on them, like phones entering individual homes. Then they transform the entire endeavor, completely surpassing the previous technology, like phones automatically connecting people without operator involvement, which enabled society to communicate in ways that telegraph users never contemplated. Cellphone cameras are following a similar path.  At the beginning cellphone cameras were imitating digital cameras, adding the convenience of carrying only one device but basically doing the same as digital cameras did.  Then they improved on them, both with quality improvements and with the ability to share pictures wirelessly without wiring the phone to a computer.  The ability to instantly share and synchronize pictures from a phone is somewhat transf...

Sensor-fusion indoor location system in over 30 malls in Singapore

SingTel just deployed indoor mapping and navigation from Swedish start-up  SenionLab  in over 30 shopping malls in Singapore, with 20 more in planning, in the biggest single deployment we've seen yet of customized indoor location technology. The most significant aspect of this deployment is that this is one of the first commercial deployments of indoor location technology that uses a new technology approach called "sensor fusion," which uses sensors in smartphones (gyroscope, compass, accelerometer, ...) to track location by sensing the phone's movements. Most indoor location systems determine location by measuring the signals of nearby Wi-Fi hotspots or cellular antennas, but this risks looking choppy as the phone waits for the radio signals to change to detect the next place it is. Sensing motion using phone sensors makes the system work more smoothly, regardless of radio signal details.  (The SenionLab solution does use Wi-Fi signals as well, to compe...
