* LEO Satellite Communication Terminal (Reference Exhibit)
Sharp will exhibit the terminal and introduce potential use cases such as real-time data transmission, location sharing, and remote control in areas with limited cellular connectivity, including maritime and mountainous regions. The terminal is also proposed as a solution for business continuity plan (BCP) during disasters. A conceptual ultra-compact model, designed for drone integration, will be presented as part of Sharp's efforts toward next-generation field solutions.

* Satellite Operation Application (Reference Exhibit)
A dedicated application supports the efficient operation and management of the LEO satellite communication terminal. It allows users to monitor terminal status, nearby obstacles, and satellite positioning. In case of a malfunction, the app provides troubleshooting guidance, streamlining maintenance tasks.

* Field Trials
Sharp will present field trials conducted using the compact and lightweight LEO satellite communication terminal, installed on vessels and vehicles. Through these tests, Sharp is accelerating development to ensure stable communication under various conditions by evaluating practical performance and identifying technical challenges.
