In an embodiment channel state information is obtained from a receiving device in a wireless network through the wireless network. A first set of beam steering vectors is derived based on the channel state information to direct a radio signal to the receiving device. A second set of beam steering vectors is derived based on the channel state information to direct a radio signal other than to the receiving device. A perturbation matrix is generated. A spatial mapping matrix is formed by combining the first and the second set of beam steering vectors with a perturbation matrix. Data symbols to be transmitted are pre-coded to the receiving device using the spatial mapping matrix and transmitted through the wireless network to the receiving device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure Wi-Fi communication by perturbation of a spatial mapping matrix","description":"Wi-Fi communication is further secured by perturbation of a spatial mapping matrix.
