Huawei IoT Gateway Zigbee physical layer technology adopts the following () standards?

The Zigbee protocol stack is fundamentally based on the IEEE 802.15.4 standard. This standard defines the specifications for the physical layer (PHY) and the media access control (MAC) layer for low-rate wireless personal area networks (LR-WPANs). Huawei's IoT gateways that support Zigbee connectivity adhere to this foundational standard to ensure interoperability and proper network function. The PHY layer handles the raw bit transmission over the radio, operating in unlicensed ISM bands like 2.4 GHz.

A. IEC104: This is a network access protocol for telecontrol applications, primarily used in electrical engineering and power system automation, not a wireless physical layer.
C. IEC103: This is a standard for the protection equipment interface, used for communication between protection relays and control systems in substations.
D. IEEE 802.15.1: This standard defines the physical and MAC layers for Bluetooth technology, which is a different short-range communication protocol from Zigbee.

1. IEEE Standard for Low-Rate Wireless Networks, IEEE Std 802.15.4-2020. Section 1, "Overview," states the standard's scope is to provide the PHY and MAC layers for LR-WPANs.

2. Zigbee Alliance. (2017). Zigbee Protocol Specification, 05-3474-21. Document 05-3474, Section 2.1.1, "IEEE 802.15.4," explicitly states that the Zigbee stack layers reside on top of the IEEE 802.15.4 PHY and MAC layers.

3. Huawei. AR502H Series IoT Gateways Datasheet. The datasheet specifies support for Zigbee, which implicitly requires adherence to the underlying IEEE 802.15.4 standard for its PHY/MAC layers.
