Final answer:
Completing a wireless site survey is crucial to determine the optimal placement of routers and assess Wi-Fi interference to ensure strong network coverage and minimize connectivity issues.
Step-by-step explanation:
It is important to complete a wireless site survey primarily to determine optimal router placement. This involves analyzing the layout of the area, detecting sources of interference, and evaluating signal strengths at different locations. By doing so, it ensures that the Wi-Fi network provides comprehensive coverage with strong signal strengths throughout the area, minimizing issues such as dead zones and weak signal. Moreover, it helps to assess Wi-Fi interference from existing networks and other electronic devices that could affect the performance of the network. Reducing interference and strategically placing routers can significantly improve the reliability and efficiency of a wireless network.
For instance, large towers used to broadcast TV signals and mobile phone towers, like those seen in Figure 24.15, demonstrate the need to have a clear line of sight over a large broadcast area. Interference from other communication systems and electronic devices that use radio-wave frequencies can be a significant problem, as each device must adhere to regulations regarding the radio frequency bands they operate within to avoid interference. A wireless survey helps in configuring the network to function optimally within these constraints.
