An Active Wi-Fi Survey is a wireless assessment methodology where a device actively connects to the wireless network while measurements are collected. Unlike passive surveys, active surveys evaluate how clients interact with the network and provide insight into real-world user experience and performance.
Why Are Active Surveys Important?
While wireless coverage is important, it does not always reflect how users experience the network. Active surveys help validate network performance by measuring connectivity, throughput and roaming behaviour from a client perspective.
This provides a more realistic view of how devices are likely to perform in everyday operation.
What Is Measured During An Active Survey?
- Network Connectivity - Confirms devices can successfully connect to the network.
- Throughput Performance - Measures data transfer performance between the client and network.
- Roaming Behaviour - Assesses how devices transition between access points.
- Application Performance - Helps validate performance for business-critical applications.
- Latency - Measures communication delays that may impact user experience.
When Should Active Surveys Be Used?
Active surveys are commonly performed during troubleshooting, validation surveys and wireless optimisation projects.
They are particularly useful when investigating user complaints relating to performance, roaming issues or application reliability.
Benefits Of Active Surveys
- Validates Network Operation - Confirms connectivity and performance while actively associated to the wireless network.
- Improved Troubleshooting - Helps identify issues affecting end-user experience.
- Assesses User Experience - Provides insight into how wireless devices interact with the network.
- Supports Optimisation - Helps identify opportunities for network improvements.
Active Surveys vs Passive Surveys
Active surveys require a device to connect to the wireless network while measurements are collected.
Passive surveys, on the other hand, observe the wireless environment without associating to the network.
Both methodologies are valuable and are often used together to provide a comprehensive assessment of wireless performance.
Key Points
- Active surveys require a device to connect to the network.
- They assess real-world user experience and performance.
- Throughput, roaming and latency can be measured.
- They are commonly used for troubleshooting and validation.
