Android 15 to Introduce Wi-FiRanging for Sub-Meter Indoor Positioning Accuracy

Google's upcoming Android 15 operating system will introduce a new technology called Wi-FiRanging, promising to significantly improve indoor positioning accuracy to within 0.4 meters. This technology builds upon the existing Wi-FiRTT (RoundTripTime) technology, utilizing radio signal time-of-flight (ToF) measurements for more precise location determination. The integration of Wi-FiRanging in Android 15 will further optimize the indoor location experience and revolutionize various industries.

Traditionally, GPS technology has struggled with low accuracy in indoor environments due to the obstruction of satellite signals by building structures. Wi-Fi signals, being relatively stable indoors, have become widely adopted for indoor positioning. However, conventional Wi-Fi positioning techniques rely mainly on signal strength (RSS) to estimate device location, resulting in accuracies ranging from 10-15 meters, failing to meet user demands for precise location information.

Wi-FiRTT technology emerged to address this issue. By measuring the time-of-flight (ToF) of radio signals, it achieves more accurate location determination with an accuracy of 1-2 meters. Compared to conventional Wi-Fi positioning, Wi-FiRTT can identify device locations more precisely, offering users more accurate indoor location services.

Wi-FiRanging technology further builds upon Wi-FiRTT, utilizing advanced algorithms and techniques to enhance location accuracy to within 0.4 meters. This technology not only supports higher bandwidth and faster transmission speeds but also provides stronger security, higher reliability, and better scalability.

Android 15's Wi-FiRanging feature will be integrated with the 802.11az standard, further improving location accuracy, expanding frequency bands, enhancing security, and enabling dynamic measurement rates. This means Android 15 will be able to deliver more accurate, secure, and reliable indoor location experiences.

Wi-FiRanging technology holds vast potential. Beyond improving indoor navigation accuracy, it can play a crucial role in smart homes, retail, and other areas:

• Smart Homes: Wi-FiRanging enables more accurate indoor positioning, allowing smart home devices to automatically adjust settings based on user location. For instance, smart lights can automatically turn on when a user enters a room, and air conditioners can adjust temperature based on user location.

• Retail: Shopping malls can utilize Wi-FiRanging to help users pinpoint product locations more precisely. Users can use their phones to find nearby products and quickly locate what they need.

• Other Areas: Wi-FiRanging can also be applied in museums, libraries, hospitals, and other areas to help users easily find their desired destinations.

While Wi-FiRanging technology has matured, its widespread adoption requires hardware and software support. Currently, some of the latest Wi-Fi chips are starting to incorporate support for this technology. Chip manufacturers like Qualcomm and Broadcom have included Wi-FiRanging support in their newest chip products. Additionally, Wi-Fi access points need firmware upgrades to work effectively with Wi-FiRanging.

As Wi-FiRanging technology continues to evolve and gain traction, more applications based on this technology are expected to emerge, bringing users a smarter and more convenient living experience.

Conclusion

The introduction of Wi-FiRanging technology in Android 15 will significantly improve indoor positioning accuracy and revolutionize industries like smart homes and retail. This technology promises to transform users' perception of indoor location, offering more accurate, convenient, and intelligent user experiences.
