What is the difference between the IEEE, the WiFi Alliance, and the FCC, ETSI, and TELEC?
A.
The IEEE and FCC are responsible for the standards that apply to wireless networks. The WiFi
Alliance, ETSI, and TELEC are the governmental agencies that regulate compliance with local
standards.
B.
The IEEE is responsible for Layer 1 and Layer 2 protocols. The WiFi Alliance is responsible for
interoperability testing. The FCC, ETSI, and TELEC are responsible for radio frequency and
transmission power-level regulations and standards in the U.S., Europe, and Japan.
C.
The IEEE is responsible for Layer 1 and Layer 2 protocols. The FCC, ETSI, and TELEC are
responsible for interoperability testing and compliance. The WiFi Alliance is responsible for radio
frequency and transmission power-level regulations and standards on a global basis.
D.
The IEEE and FCC are responsible for the Layer 3 protocol support and frequency and powerlevel regulations in the United States. ETSI and TELEC are responsible for frequency and powerlevel regulations in Europe and Japan. The WiFi Alliance is responsible to interoperability testing.

IEEE 802 divides the data link layer into two sublayers:[5]
Media Access Control (MAC) layer – responsible for controlling how devices in a network gain access to medium and permission to transmit it.
Logical Link Control (LLC) layer – responsible for identifying Network layer protocols and then encapsulating them and controls error checking and frame synchronization.
The MAC and LLC layers of IEEE 802 networks such as 802.3 Ethernet, 802.11 Wi-Fi, and 802.15.4 ZigBee, operate at the data link layer.
Wi-Fi Alliance is a non-profit organization that promotes Wi-Fi technology and certifies Wi-Fi products if they conform to certain standards of interoperability.
IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands.
