Modulation and Coding Schemes (MCS)

Modulation and Coding Schemes (MCS) refer to methods used in wireless communication to efficiently transmit data. Modulation determines how data is represented as radio signals, while coding adds error correction to improve reliability. Different MCS levels balance data speed and signal robustness: higher levels offer faster data transfer but require better signal quality, whereas lower ones ensure steady communication in challenging conditions. Devices select an appropriate MCS based on current signal quality, optimizing performance and connection stability.
