METHOD AND APPARATUS FOR BEAMFORMING FEEDBACK REDUCTION IN WIRELESS LOCAL AREA NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240306005 titled 'METHOD AND APPARATUS FOR BEAMFORMING FEEDBACK REDUCTION IN WIRELESS LOCAL AREA NETWORKS
The abstract describes a patent application for a wireless local area network (WLAN) apparatus that communicates with another apparatus to perform beamforming for data transmission.
- The apparatus includes a transceiver and at least one processor.
- The processor receives a null data packet (NDP) from the other apparatus and generates a channel estimate based on the NDP.
- It decomposes the channel estimate to obtain a feedback matrix, which is used to obtain beamforming information for the other apparatus.
- The apparatus then transmits the beamforming information to the other apparatus and receives a beamformed data transmission based on this information.
- The beamforming information includes angle indices and a steering matrix index for beamforming the data transmission.
Potential Applications: - This technology can be used in wireless communication systems to improve the efficiency and reliability of data transmission. - It can enhance the performance of WLAN devices in crowded or noisy environments by optimizing the beamforming process.
Problems Solved: - Addressing the challenges of interference and signal degradation in wireless communication. - Improving the overall quality of data transmission in WLAN networks.
Benefits: - Enhanced data transmission quality and reliability. - Increased efficiency and speed of wireless communication. - Improved performance in challenging wireless environments.
Commercial Applications: - This technology can be applied in various industries such as telecommunications, IoT, and smart home devices. - It can be integrated into routers, access points, and other WLAN devices to enhance their performance and reliability.
Questions about the technology: 1. How does beamforming improve the performance of wireless communication systems? 2. What are the key advantages of using beamforming in WLAN networks?
Frequently Updated Research: - Stay updated on the latest advancements in beamforming technology for wireless communication systems. - Monitor research on optimizing beamforming algorithms for improved data transmission in WLAN networks.
