Zigbee primarily uses Direct Sequence Spread Spectrum (DSSS) as its modulation technique. Specifically, it employs Offset Quadrature Phase Shift Keying (O-QPSK) in the 2.4 GHz frequency band. This approach allows Zigbee to achieve reliable, low-power wireless communication suitable for short-range applications.
