NextNav can figure out which floor you’re on in a skyscraper

NextNav has found out find out how to use barometric stress sensors and different networks to find out what ground of a constructing an individual is on after they’re calling from a skyscraper or different multi-floor constructing. And it does so utilizing software program that may work with sensors which have been in smartphones for years.

The Federal Communications Commission on Thursday voted five-to-zero in favor of including a requirement that smartphones mark the placement inside three meters of altitude for all 911 calls. That was precisely what NextNav hoped for, as the corporate offers an answer that may assist smartphone makers meet that mandate.

FCC commissioner Brendan Carr mentioned in a listening to on Thursday that know-how might help enhance the response for 911, whereas Commissioner Jessica Rosenworcel mentioned that 911 ought to merely work for all folks all the time, and meaning requiring that units present floor-level accuracy with out fail. The FCC mandate may go into impact by April 2021.

All of that is music to the ears of the oldsters at Sunnyvale, California-based NextNav, which raised $120 million in January and, after 13 years of growth, is lastly able to deliver the know-how into the market.

“We’ve been developing this technology in the background, and there are a lot of technical barriers and regulatory barriers that we had to break through,” NextNav head of promoting Ben Ball mentioned in an interview with VentureBeat.

How it really works

Global positioning system (GPS) navigation has been doable due to satellite tv for pc networks for the reason that 1990s, however that solely allowed folks to determine the place they’re in a two-dimensional grid. The third dimension, or the “missing Z-axis,” is the place that individual is vertically.

GPS is susceptible in some methods as a result of folks actually don’t know precisely the place some objects are, mentioned Dan Hight, vice chairman and normal supervisor of information partnerships at NextNav, in an interview with VentureBeat. GPS was by no means designed to trace folks or small objects like supply packages.

“Satellites can’t see it. And that presents a very large challenge for public safety,” Hight mentioned. “Fire departments need to know where people are inside tall buildings. As you can imagine, when you need medical attention, or you’re in an emergency situation, every second counts, and so finding people within large urban areas and very large buildings is becoming an increasingly large problem.”

In locations comparable to Las Vegas, navigation applications can use indoor Wi-Fi or Bluetooth indicators to trace how close to an individual is to a given wi-fi router, and that permits the apps to trace the place somebody is inside a on line casino. But not all buildings have Wi-Fi indicators, and that doesn’t assist in fixing a vertical location.

NextNav has constructed a community of wi-fi long-range beacons which can be kilometers aside. Dubbed Metropolitan Beacon Systems, or MBS, the beacons work with the mobile system to find out the place somebody is in a three-dimensional house. It doesn’t require its beacons to be inside buildings. NextNav additionally faucets barometer sensors which can be constructed into smartphones. These detect barometric stress, which adjustments with altitude, and it could possibly assist repair the place an individual is positioned.

As you go up an elevator, the barometric stress goes down. A storm may have an effect on that barometric stress, however NextNav is taking a look at minute adjustments in stress, along with the calibration community that it has arrange with the beacons. The firm says it could possibly get vertical accuracy inside one to 2 meters.

The system has gone by quite a lot of third-party testing, Hight mentioned. The MBS is ready up in just a few areas now, just like the San Francisco Bay Area and Washington, D.C.

Growing alternatives

NextNav has been engaged on the tech for some time, and it offers vertical info to NASA in a program that permits the company to maintain track of drone locations.

In suburban areas, top is never a problem. But in large cities and different city areas, having the ground location will be extraordinarily essential, and roughly 84% of the U.S. population lives in city areas the place multistory buildings make up a lot of the panorama. In locations like midtown Manhattan, Chicago’s Loop, or San Francisco’s Financial District, there aren’t a complete lot of open, public areas. Inside procuring malls, it isn’t simple to search out somebody, as satellite tv for pc indicators don’t penetrate buildings.

Beyond offering exact location coordinates for 911 calls, NextNav is engaged on different functions. It may, for example, be utilized in augmented actuality video games, the place a treasure is hidden on the highest ground of a constructing. Urban areas are an enormous alternative for AR video games, and that interprets to an enormous enterprise alternative. Manhattan alone has 568 million square feet of workplace house that’s presently inaccessible for AR functions just because present geolocation companies don’t account for the Z-axis.

Multistory buildings provide a golden alternative as gaming venues for public or non-public occasions. Think a couple of team-building train the place individuals discover clues on totally different flooring of a skyscraper. The escape room trade, which plateaued in 2019, may increase into complete “escape buildings” — a brand new market simply ready to be exploited, the corporate mentioned.

“We’re looking into what consumers can do with it, what they can do with gaming, what we can do with advertising,” mentioned Hight.

Niantic (the creator of Pokémon Go), Facebook, and others have already acknowledged the potential of 3D AR, investing within the house by a sequence of acquisitions. Apple, Microsoft, Google, and others are constructing out the back-end know-how wanted to deliver AR worlds to life.

“We’ve been chipping away at this for a very long time,” Ball mentioned. “I think in the last two years or so, we’ve really started to gain a lot of momentum in the space, which is evidenced by a lot of funding rounds.”
