CWT WLAN Installation & Configuration

Question 1

What is the first step in installing a WLAN?

Accepted Answer

Conduct a site survey

Answer

Conducting a site survey is the crucial first step in installing a Wireless Local Area Network (WLAN). This process involves physically assessing the environment to identify optimal access point locations, potential sources of interference, and coverage gaps. A thorough site survey ensures the network design provides adequate signal strength, performance, and reliability throughout the intended coverage area.

Question 2

Which tool is used to measure signal strength during installation?

Accepted Answer

Wi-Fi analyzer

Answer

A Wi-Fi analyzer is a specialized software or hardware tool used to scan, identify, and analyze wireless networks in a given area. It provides critical information such as signal strength (RSSI), channel utilization, and potential interference sources. This data is essential for optimizing access point placement and channel selection during WLAN installation to ensure optimal performance.

Question 3

Why is channel selection important in WLAN setup?

Accepted Answer

It reduces wireless interference

Answer

Proper channel selection is critical in WLAN setup to minimize interference from other Wi-Fi networks and devices operating on the same or overlapping frequencies. By choosing non-overlapping channels, especially in the crowded 2.4 GHz band, network performance can be significantly improved. This reduces signal collisions, leading to more stable connections and higher data throughput for users.

Question 4

What setting determines how far a Wi-Fi signal can reach?

Accepted Answer

Transmit power

Answer

Transmit power refers to the strength of the radio signal emitted by a Wi-Fi access point or client device. Increasing the transmit power can extend the physical range of the Wi-Fi signal, allowing it to cover a larger area or penetrate obstacles more effectively. However, excessive power can also lead to interference with other networks and may not always be the optimal solution for coverage.

Question 5

What is SSID in WLAN configuration?

Accepted Answer

Service Set Identifier

Answer

SSID stands for Service Set Identifier, which is the name of a Wi-Fi network. It acts as a unique identifier that allows users to distinguish and select a specific wireless network from others available in their vicinity. While it can be broadcast or hidden, it's the primary way users identify and connect to a WLAN.
