Why each option
IEEE 802.15.4 defines the Low-Rate Wireless Network standard and is the foundational data link layer technology used in IoT access networks for low-power, low-bandwidth devices.
Wireless Regional Area Networks correspond to IEEE 802.22, which is designed for long-range rural broadband, not IoT device connectivity.
IEEE 802.15.4 specifies the physical and MAC layer for low-rate wireless personal area networks (LR-WPANs), making it ideal for IoT environments where devices require low power consumption and low data rates. It underpins widely used IoT protocols such as Zigbee, Thread, and 6LoWPAN, all of which operate at the IoT access network edge.
Wireless Local Area Networks correspond to IEEE 802.11 (Wi-Fi), which is higher power and higher bandwidth than needed for typical IoT edge devices.
Broadband wireless metropolitan networks correspond to IEEE 802.16 (WiMAX), which targets wide-area broadband access rather than low-rate IoT device communication.
