Key Points of This Article

• Our independent investigation discovered that the internal code of version 3.1.399-9 of the Android “Find Hub” app, distributed around September 22, 2025 (Monday), includes a new ranging permission: “Ranging (android.permission.RANGING)”.
• The “Ranging” permission in Android, introduced from Android 12 (API Level 31) onwards, is a ranging permission that uses “Wi-Fi Round-Trip-Time (RTT)” technology to measure the distance to Wi-Fi access points by utilizing the round-trip time of Wi-Fi signals, thereby determining device location.
• If “Ranging (Wi-Fi RTT)” is implemented in the Android “Find Hub” app, it will enable high-precision location determination using “Wi-Fi RTT” even for Android devices not equipped with Ultra-Wideband (UWB) wireless communication.

Google’s “Find Hub” (Google’s Find Hub), a location determination service, has evolved into a service that determines location information using a network of over 3 billion Android devices worldwide.

The location determination capabilities of “Find Hub” may be further enhanced. Our independent investigation has uncovered that a new ranging permission, “Ranging (android.permission.RANGING)”, has been added to the internal code of version 3.1.399-9 of the Android “Find Hub” app, distributed around September 22, 2025 (Monday).

The “Ranging” permission in Android, introduced from Android 12 (API Level 31) onwards, is a ranging permission that utilizes “Wi-Fi Round-Trip-Time (RTT)” technology to measure the distance to Wi-Fi access points by measuring the round-trip time of Wi-Fi signals, thereby determining device location. If this “Ranging (Wi-Fi RTT)” is implemented in the Android “Find Hub” app, it will enable high-precision location determination using “Wi-Fi RTT” even for Android devices not equipped with Ultra-Wideband (UWB) wireless communication.

Incidentally, Google’s smart display “Nest Hub” and other devices are already equipped with “Wi-Fi RTT” and utilize it for determining the location of “Find Hub” compatible devices. This means that the “Wi-Fi RTT” location determination functionality, similar to that of “Nest Hub,” may be released for Android devices through the Android “Find Hub” app in the future. We look forward to Google’s future announcements.
