Wireless Site Survey Types: Predictive, Passive, and Active Surveys Explained
Wireless site survey types serve different purposes in WiFi network planning. Indeed, predictive site survey uses software modeling before installation. Furthermore, passive WiFi survey measures existing RF environment without connecting. Additionally, active wireless survey tests actual client performance and throughput. Moreover, each survey type has specific use cases, tools, and costs. Therefore, understanding wireless site survey types helps businesses choose the right approach for their WiFi planning needs ensuring optimal network design and reliable performance.
Understanding the Three Survey Types
Each wireless site survey type provides different information. For instance, predictive surveys model coverage before installation. Passive surveys measure real-world RF environment. Furthermore, active surveys test actual network performance. Different project phases need different survey types. Consequently, wireless site survey types work together providing complete picture from initial planning through post-installation validation.
Why Multiple Survey Types Matter
No single survey type tells the whole story. For example, predictive surveys can’t detect interference. Passive surveys don’t test throughput. Furthermore, active surveys require existing network. Using appropriate survey types at right times ensures accurate design. Therefore, predictive site survey, passive WiFi survey, and active wireless survey each play important roles in comprehensive wireless planning.
Predictive Site Surveys
Predictive surveys use software to model WiFi coverage before installation.
What is a Predictive Survey
Predictive surveys create virtual network designs. For instance, import floor plans into specialized software. Define building materials and wall types.
