Question

What is the purpose of the 802.11 wireless local area network (LAN) superframe?

a) To provide collision detection in the network.
b) To monitor network traffic.
c) To transmit data in optical fibers.
d) To regulate the power supply to devices.

Answer 1

The purpose of the 802.11 wireless local area network (LAN) superframe is b) To monitor network traffic.

Step-by-step explanation:

The 802.11 wireless LAN superframe is a structure that organizes the time and frequency resources within a wireless network. It consists of contention-free periods (CFPs) and contention periods (CPs). During the CFP, specific time slots are allocated for controlled access, allowing devices to transmit data without contention. In the CP, devices contend for the channel using protocols like Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA).

While collision detection (Option A) is a function in wired networks, it is less relevant in wireless networks due to the nature of radio wave transmission. The 802.11 superframe is primarily designed to organize and monitor network traffic efficiently.

Option B is the answer.
