Description
Wi-Fi 6, also known as 802.11ax, represents the sixth generation of Wi-Fi standards, offering significant improvements over the predecessor, Wi-Fi 5 (802.11ac). Released in 2019, Wi-Fi 6 is designed to operate in high-density environments and also improve performance and efficiency. Wi-Fi 6 introduces advanced technologies such as Orthogonal Frequency Division Multiple Access (OFDMA), 1024-QAM modulation, Target Wake Time (TWT), and improved Multiple-Input Multiple-Output (MIMO) support.
Beamforming is a technique used in Wi-Fi networks to focus wireless signals directly toward connected devices rather than broadcasting signals in all directions. This focused signal improves both the strength and efficiency of the connection, reducing interference and delivering a faster, more reliable Wi-Fi experience. Beamforming is particularly helpful in dense environments where multiple devices compete for bandwidth, as it allows the router to direct its signal more precisely, enhancing coverage and reducing wasted energy.
This report contains information on the patent landscape relating to beamforming. The future of beamforming and the patents connected to the technology are largely correlated to the evolution of the Wi-Fi service. Beamforming efficacy has improved during the Wi-Fi 6 generation, and there is an interdependent relationship insofar as Wi-Fi 6 has increased the number of MU-MIMO users, and this was also made possible by the use of beamforming.
