   - Broadcasting the message schedule to multiple STAs.
   - Receiving FTM messages from STAs based on the schedule.
   - Determining distances between the AP and STAs using the FTM messages.
  • **Potential Applications:**
   - Indoor positioning systems.
   - Asset tracking in warehouses.
   - Location-based services in smart cities.
  • **Problems Solved:**
   - Improving accuracy in distance measurement.
   - Enhancing synchronization in wireless networks.
   - Facilitating efficient data transmission.
  • **Benefits:**
   - Increased precision in location tracking.
   - Enhanced network performance.
   - Improved reliability of wireless communication.
  • **Commercial Applications:**
   - IoT devices for real-time tracking.
   - Smart home automation systems.
   - Industrial automation solutions.
  • **Prior Art:**
   Prior art related to this technology may include research on FTM in wireless networks, indoor positioning systems, and distance measurement techniques.
  • **Frequently Updated Research:**
   Ongoing research in the field of wireless communication protocols, indoor positioning technologies, and network synchronization methods may be relevant to this technology.

Questions about Wireless Communication Techniques: 1. How does the message schedule for FTM improve distance measurement accuracy? 2. What are the potential challenges in implementing these techniques in real-world wireless networks?


Original Abstract Submitted

Techniques for wireless communication are disclosed. These techniques include defining a message schedule for fine time measurement (FTM) at a first wireless access point (AP). The techniques further include broadcasting the message schedule to a plurality of wireless stations (STAs) from the first AP. The techniques further include receiving, at the first AP, a plurality of FTM messages from the plurality of STAs, the messages transmitted by the plurality of STAs based on the message schedule. The techniques further include determining a distance between the first AP and each of the plurality of STAs based on the plurality of FTM messages.
