Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Multi-antenna wireless communication systems, such as beamforming schemes, require frequent link-maintenance operations that consume bandwidth and can interrupt communications, particularly in directional signal transmission and reception scenarios like millimeter wave communication.

Innovation Solution

Implementing an orientation-related attribute controller that adjusts beamforming parameters and antenna schemes based on the orientation of wireless communication devices, allowing for autonomous maintenance and adjustment of beamformed links without involving the responder device, thereby reducing the need for conventional link-maintenance operations that consume bandwidth and cause interruptions.
