The Problem with Traditional Communication Networks
Traditional communication networks rely on radio waves, which are affected by atmospheric conditions, interference, and signal degradation. This can lead to dropped calls, delayed data transmission, and even complete system failures. In space, the problem is exacerbated by the sheer distance between Earth and other celestial bodies, making it challenging to maintain a stable and reliable connection.
