How to get one-meter location-accuracy from Android devices (Google I/O ’18)


  1. Exciting stuff, and great presentation! Could you please post the slides as well? It's hard to see details on some of them due to video quality. Thanks!

    EDIT July 11th – A written article version of this presentation is now available on GPS World –

  2. The most interesting part is from 12:00 to 14:00, where he explains how it works, I wish that could have been expanded by about 30 minutes, I was on both Polaris and Poseidon subs in navigation. I can tell you, you do not want to use Maximum likelihood, you do want to use a Kalman Filter . The different is like night to daylight.

  3. When will 802.11mc RTT be available on the Google WiFi product (mesh network) ? What other APs do or are roadmapped to support RTT? When will fused location services support indoor positioning via RTT ?

  4. I just noticed this Video is 39:27 wow, Not got time for this, I have left the Building, as most of the Audience appear to have done after 10 minutes, I use Google® Maps and a dedicated Sat-Nav as back up and find in any blind spots the 2 work together ok. My Sat-Nav is much quicker to re-route as it does not depend on internet connection.

  5. Get me outa here….I just received a flashback from my Engineering University days. Nothing like a bunch of geeks making a complicated issue even more complicated. Thanks anyways, Cheers.

  6. the part of 16:04, i saw the google wifi blue color router, i want to know it, is it commercial? where can i buy it? i want to meassure distance with my google pixel, what is the brand name of the phone that can work with this?

  7. i want to notice the video is 16:02 ,the special Google WIFI RTT blue color router , 1.) Is it available to buy it? 2.) where do they sell it ? 3.) how much is the cost per one ? i used google wifi router and test with my google pixel 3a xl , i tested with google wifi rtt scan app , it works ,but the accuracy is not accurate within 1 m. just about +- 3 m., i tested in my living room in the apartment ,so when i saw this Video at 16:02 ,i am interested in special google wifi blue color router because it is very accurate , less than 1m. that why i want to buy it, because i want to test measurement as the google conference in the Video at 16:02 , and the next question are , 4.)are there other brand name of wifi rtt router ? 5.)what are the name of each brand name of wifi rtt router ? because normal router without 802.11 mc , can not do it ,6.) will only the phone with android p able to test measuring the distance from RTT ? 7.) does the phone need to have the chip of 802.11 mc embedding to test measuring the distance from RTT 8.) now what are the brand of the phone that can test measuring with RTT , because in my knowledge , the app that is available to test measurement is only wifi rtt scan app , i can download with google pixel 3a xl , that run android p operating system , i think there also is the chip of 802 . 11 mc embedding in the google pixel 3a xl ,but when i used other new phone that run the android p , for example , new samsung galaxy 9 or10,nor the phone that have API more higher than 26, it can not download the wifi rtt scan app, so if someone know the answer ,please let me know my 8 questions
