  • Physical layer key based interleaving for secure wireless communication
    Patent number: 11540120
    Abstract: A key-based interleaver for enhancement the security of wireless communication includes a physical layer communication channel key to provide security even when the software encryption key is compromised. A method of creating a secure communication link using a physical layer interleaving system includes implementing a key policy implementation that utilizes temporal dependency and interleaving bits using a flexible inter and intra-block data interleaver.
    Type: Grant

  • Physical gate based preamble obfuscation for securing wireless communication
    Patent number: 11177902
    Abstract: A physical layer based technique secures wireless communication between a transmitter and receiver. The technique involves obfuscating the preamble data of the baseband signal through unique keys that are generated at the transmitter and the receiver based on channel characteristics known only to them.

  • Beam visualization and using augmented reality for control and interaction
    Patent number: 10515483
    Abstract: Presenting a visualization of antenna radiation patterns may include sending a request to a server for up-to-date information regarding an antenna mode; receiving the request at the server and reading a register value for the antenna mode; responding, by the server, with updated antenna mode information; and overlaying antenna radiation patterns on an image based on the mode information.
