    Unlike fiber optics (纤维光学), satellites can send data to any point on earth, at sea or in the air—all at the same time. Nor are they as vulnerable (易受伤的) to great natural disasters like flood and earthquakes.
    Satellites are essential for today’s broadcast, cable, business, TV, radio, data delivery, educational programming and telephone industries.
