DSSS stands for “Direct Sequence Spread Spectrum.” It’s a modulation technique used in wireless communication systems to spread the signal across a wider bandwidth. This technique involves multiplying the original signal by a spreading code, which effectively spreads the signal’s energy over a larger frequency range. DSSS helps increase the signal’s resistance to interference and provides greater security. It’s commonly used in technologies like Wi-Fi (802.11b) and some forms of CDMA (Code Division Multiple Access) for cellular networks.
