64-QAM

64-QAM (Quadrature Amplitude Modulation) is a method used in digital communication to transmit data efficiently over radio waves or cables. It encodes data by changing the signal's amplitude and phase into 64 different combinations, each representing a unique 6-bit binary number. This allows for sending more data simultaneously within the same bandwidth, improving transmission speed. Think of it like a complex code that uses multiple levels of "waves" to carry information quickly and accurately, making it ideal for high-speed internet and digital TV signals.
