DJI SDR Transmission
DJI SDR Transmission สร้างขึ้นบนพื้นฐานเทคโนโลยีวิทยุกระจายเสียงที่เป็นการสื่อสารไร้สายที่กำหนดโดยซอฟต์แวร์ ซึ่งสามารถใช้ได้ทั้งโหมดส่งสัญญาณ SDR และ Wi-Fi. เทคโนโลยี SDR ได้มายกระดับประสิทธิภาพการส่งสัญญาณวิดีโอไปอีกขั้น โดยให้ความเสถียรที่ดียิ่งขึ้น ป้องกันสัญญาณรบกวน สามารถรับส่งสัญญาณภาพได้อย่างราบรื่น ในกรณีที่คุณต้องการ monitoring ทาง DJI SDR Transmission ก็ยังสามารถรองรับการส่งสัญญาณผ่าน Wi-Fi เพื่อให้ทีมงานทำงานร่วมกันได้อย่างสะดวกมากยิ่งขึ้น
