ZigBee relies on which IEEE 802.x standard?

Explanation:
ZigBee is built on the IEEE 802.15.4 standard, which defines the physical and MAC layers for low-rate wireless personal area networks. This foundation is exactly what ZigBee needs: a lightweight, low-power, short-range radio with simple channel access that supports many devices in a mesh or star topology. The other standards serve different purposes—802.11 is high-speed Wi‑Fi, 802.3 is wired Ethernet, and 802.16 (WiMAX) targets broadband wireless access—so they don’t provide the low-power, low-data-rate foundation ZigBee uses. ZigBee adds its own network and application layers on top of 802.15.4 to enable device roles, routing, and application profiles.
