Samsung patents math method to improve Wi-Fi signal direction
Samsung describes a method for Wi-Fi devices to calculate the best way to direct their signal using a mathematical technique called singular value decomposition. The device sends specific data to nearby access points so they can adjust their signal beams more effectively.
In the filing’s own words
A method, system, and station are disclosed for forming, optimal singular value decomposition based beamforming. The method, system, and station may form, with a first station (STA1), a normalized-optimal STA1 CSI feedback matrix V 1 with an optimal STA1-first access point (AP1) intra-basic service set (BSS) right singular matrix {tilde over (V)} 11, a normalized new STA1-second access point (AP2) cross-BSS right singular matrix V ¯ 12 new, and a null matrix. The method, system, and station also sends, with the STA1, the normalized-optimal STA1 CSI feedback matrix V 1 to the AP1 and AP2 for more than one type of beamforming.
What exactly they claim (claim 1)
1. A method comprising: forming, with a first station (STA1), a normalized-optimal STA1 channel state information (CSI) feedback matrix V 1 with an optimal STA1-first access point (AP1) intra-basic service set (BSS) right singular matrix {tilde over (V)} 11, a normalized new STA1-second access point (AP2) cross-BSS right singular matrix V ¯ 12 new, and a null matrix; and sending, with the STA1, the normalized-optimal STA1 CSI feedback matrix V 1 to the AP1 and AP2 for more than one type of beamforming.
