GPS struggles with indoor navigation, but advancements in Wi-Fi-based positioning are changing that. Traditional Wi-Fi tracking, based on signal strength, offered limited accuracy (10-15m). The introduction of the Wi-Fi Round Trip Time (RTT) standard (802.11mc) improved accuracy to 1-2m by measuring signal travel time between devices and access points (APs). While Android has supported Wi-Fi RTT since 2018, its adoption has been limited due to a lack of compatible APs.
The new 802.11az standard, or Wi-Fi Ranging, takes accuracy further, down to 0.4m, while also offering better security, scalability and 6GHz band support. Android 15 will enable apps to use this technology where supported, paving the way for more precise indoor navigation, smart home features and contextual app experiences. However, widespread use depends on hardware and firmware updates in both phones and APs.
