Satellite connectivity refers to the ability of devices, such as smartphones or computers, to communicate directly with satellites orbiting the Earth. This technology enables data transmission, voice calls, and internet access in areas where traditional cellular networks or wired connections are unavailable or unreliable. By bypassing ground-based infrastructure like cell towers, satellite connectivity provides global coverage, making it essential for remote locations, emergency situations, and maritime or aviation communications. It plays a critical role in bridging the digital divide and supporting secure, resilient communications worldwide.
