Title: Haopeng Li: Wireless Networking and Locationing Innovations.

Introduction.

Haopeng Li is an inventor based in Fremont, California, whose patent work addresses wireless communication and device locationing. He works at Amazon Technologies, Inc. His portfolio includes 2 patents.

Latest Patents.

Li’s patent work includes technologies for delivering multimedia over an extended-range wireless local area network (WLAN), such as IEEE 802.11ah. One described method assigns different priority values to portions of media data. It uses a modulation and coding scheme with symbol repetition for the higher-priority portion, then transmits the lower-priority portion using a scheme without symbol repetition. This approach is designed to give higher-priority media data more robust transmission.

Another patent concerns detecting and locating devices within a wireless network. The described method uses Fine Timing Measurement (FTM) procedures between wireless devices, including an off-channel connection. By measuring signal round-trip time and estimating the distance between devices, the system can determine a device’s location.

Career Highlights.

Li’s listed inventions focus on practical wireless-network capabilities: prioritizing multimedia traffic and estimating device locations through timing measurements. Together, these areas reflect work on both the delivery of data and the detection of devices in wireless environments.
