What is an important purpose of conducting wireless site surveys before deployment?

Conducting wireless site surveys before deployment is crucial for measuring existing wireless signals and interference. This helps network designers identify coverage gaps, areas of potential co-channel interference, and sources of noise or other obstructions that could impact the performance of the wireless network. By understanding the existing radio frequency environment, it becomes easier to plan for optimal access point placement, ensuring adequate coverage, signal strength, and network reliability.

This step inherently leads to a more effective and efficient wireless network deployment. Properly assessing the environment helps in designing a network that can handle current demands while being resilient to interference, thus contributing to a better user experience and overall network performance. Additionally, it assists in minimizing the need for adjustments after deployment, which can save time and resources.
