1Productivity
If existing wireless communication standards (IEEE 802.11ad/ay) are directly applied to wireless AV systems, then basic communication functionality is achieved, but efficient data transmission for high-resolution video is difficult to expect
Solution Approach 1:
The patent modifies communication parameters including defining specific operation modes (initial connection establishment mode, data transfer mode, stand-by mode, connection re-establishment mode), adjusting beamforming training procedures, and optimizing connection setup parameters to suit wireless AV system requirements while maintaining compatibility with IEEE 802.11ad/ay standards
Solution Approach 2:
The patent creates a universal communication framework that can handle multiple functions within wireless AV systems, including initial connection establishment, continuous data transfer, power management through stand-by mode, and connection re-establishment, making the system adaptable to various wireless AV applications
2Reliability
If connection setup procedures are performed frequently to maintain connection quality, then connection reliability is improved, but transmission delay and power consumption increase
Solution Approach 1:
The patent implements periodic connection maintenance through defined operation modes where beamforming training and connection setup are performed at specific intervals rather than continuously, reducing unnecessary overhead while maintaining connection quality through scheduled re-establishment procedures
Solution Approach 2:
The patent introduces dynamic mode switching between initial connection establishment mode, data transfer mode, and connection re-establishment mode based on connection quality and operational requirements, allowing the system to adapt connection setup frequency to actual needs rather than following a fixed schedule
3Reliability
If beamforming training is performed continuously to maintain directional signal quality, then signal quality is improved, but power consumption and processing overhead increase
Solution Approach 1:
The patent implements periodic beamforming training within the defined operation modes, performing sector level sweep and beamforming setup during initial connection establishment and connection re-establishment modes, while maintaining signal quality through scheduled training rather than continuous operation
Solution Approach 2:
The patent introduces dynamic adjustment of beamforming training frequency based on operational mode and connection quality requirements, performing intensive training during mode transitions and reducing training activity during stable data transfer mode to optimize power consumption while maintaining signal quality
