Android Pie Wifi RTT
Google launched Wi-Fi RTT feature with Android newely launched Android Pie version. What is Wi-Fi RTT? Wi-Fi RTT(Round-Trip-Time) is a part of the IEEE 802.11mc( iEEE_802.11mc ) specification. This specification defines how to determine a device’s distance from peer devices and supporting Access Points. Given the location and distances from three(two or more) different WiFi Access Points(APs). Benifits of Wi-Fi RTT Indoor navigation Smart home voice commands How Does Wi-Fi RTT Work? Deterime the device’s distance from supporting acces points using physics formula, distance = speed * time. Which can be used in the multilateration algorithm. Requirements The hardware of the device making the ranging request implement the 802.11mc FTM standard. The access point implement the IEEE 802.11mc( iEEE_802.11mc ) FTM standard. The device making the ranging request must have Wi-Fi scanning turned on and location services enabled. The app making the ranging r...
