What is the Bluetooth Protocol Number?

• A. 802.11
• B. 802.15.1
• C. 802.3
• D. 802.5

Answer: (B)

Bluetooth is defined within the IEEE 802.15 family, and its formal protocol number is 802.15.1. This distinguishes it from other wireless standards like 802.11 (Wi‑Fi), 802.3 (Ethernet), and 802.5 (Token Ring). The 802.15.1 designation is the IEEE standard associated with the Bluetooth core specification, even though Bluetooth versions and profiles (BR/EDR, BLE) are governed by the Bluetooth Core Specification. So the correct identification is 802.15.1.
