What is the purpose of conducting a wireless site survey?

• A. To measure the physical dimensions of the site.
• B. To determine coverage, capacity, and interference, guiding AP placement, power levels, and channel planning.
• C. To configure IP addresses for clients.
• D. To calculate the budget for network maintenance.

Answer: (B)

The goal of a wireless site survey is to determine how the wireless network will perform in the space by evaluating coverage, capacity, and interference. This information shows where access points should be placed, what transmit power to use, and how to plan channels so signals don’t clash and performance stays strong. By measuring signal strength, data rates, noise, and the presence of other networks or RF sources, the survey identifies dead zones to eliminate, ensures there’s enough bandwidth for the expected number of devices, and optimizes the use of the available spectrum. It’s about shaping the RF design to deliver reliable wireless access, not about measuring room dimensions, configuring client IP addresses, or budgeting for maintenance.
