An APoS (Access Point on a Stick) survey is a wireless survey methodology used to validate a proposed wireless design before permanent installation. The process involves temporarily deploying wireless access points within the environment to assess real-world coverage and performance. This helps identify potential design issues early and provides greater confidence before equipment is permanently installed.
What Does APoS Mean?
APoS stands for Access Point on a Stick. During an APoS survey, wireless access points are temporarily mounted using survey poles or similar equipment and positioned at the proposed installation locations. Engineers then collect wireless measurements throughout the environment to assess how the network is likely to perform once deployed.
When Is An APoS Survey Used?
APoS surveys are commonly performed after a predictive wireless design has been completed and before permanent installation begins.
They are particularly valuable in environments where wireless performance is business critical or where building materials and environmental factors may impact signal propagation.
- Warehouses - High ceilings and metal racking can significantly affect wireless coverage.
- Office Environments - Helps validate coverage and roaming requirements.
- Educational Facilities - Supports high-density wireless deployments.
- Healthcare Facilities - Ensures reliable connectivity for critical services.
- Manufacturing Sites - Identifies potential RF challenges before deployment.
Benefits Of An APoS Survey
- Validates Design Assumptions - Confirms that the proposed design performs as expected in the real environment.
- Reduces Deployment Risk - Identifies potential coverage and performance issues before installation.
- Improves Design Accuracy - Provides real-world wireless measurements rather than relying solely on modelling.
- Supports Business-Critical Deployments - Provides additional confidence for environments where reliable connectivity is essential.
What Information Is Collected?
During an APoS survey, engineers typically collect information relating to wireless coverage, signal quality, roaming performance, channel utilisation and environmental characteristics that may influence the final design.
The survey may also identify installation constraints such as mounting options, cabling routes and physical obstacles that could affect deployment.
APoS Survey vs Predictive Wireless Design
A predictive wireless design uses software modelling to estimate wireless coverage and performance. An APoS survey takes the next step by validating those predictions using real wireless hardware within the actual environment.
For many projects, both methodologies are used together to achieve the best possible outcome.
