Question

In a wireless network, an extended service set is considered to be a set of

• A. Access Points
• B. Basic service sets
• C. Mobile stations
• D. None of the above

Hint:

An Extended Service Set (ESS) is a combination of multiple Basic Service Sets (BSSs) interconnected through a distribution system, allowing seamless wireless coverage.

Answer 1

The Correct Option is B

Step 1: Understanding Wireless Networks
A wireless network is structured using service sets to manage connectivity and coverage.
Step 2: Types of Service Sets
- Basic Service Set (BSS): The fundamental building block of a wireless network consisting of a single access point (AP) and associated stations.
- Extended Service Set (ESS): A collection of multiple BSSs interconnected by a distribution system (DS), allowing seamless communication over a wider area.
- Mobile Stations: Devices like laptops or smartphones that connect to a BSS or ESS.
Step 3: Analyzing the Correct Option
- Option (A) Access Points: Incorrect, as an ESS consists of multiple BSSs, not just APs.
- Option (B) Basic Service Sets (Correct): An extended service set is formed by interconnecting multiple BSSs.
- Option (C) Mobile Stations: Incorrect, as stations connect within a BSS or ESS but do not define it.
- Option (D) None of the above: Incorrect, as BSSs form the ESS.
