Which standard is also known as WiMAX and provides fixed broadband wireless metropolitan access networks using a point-to-multipoint architecture?

• A. IEEE 802.16
• B. IEEE 802.11
• C. IEEE 802.15.4
• D. IEEE 802.15.1

Answer: (A)

WiMAX, defined by IEEE 802.16, is designed for fixed broadband wireless access over a metropolitan area. It provides last‑mile connectivity from a base station to many subscriber terminals in a point‑to‑multipoint arrangement, making it well suited for fixed wireless MAN deployments. The other standards serve different roles: IEEE 802.11 is for local area wireless networks (Wi‑Fi), IEEE 802.15.4 targets low‑rate wireless personal area networks (like ZigBee), and IEEE 802.15.1 is Bluetooth for short-range personal area networking. So the standard known as WiMAX that fits the description is IEEE 802.16.
