A validation survey is performed after a wireless network has been deployed to verify that it meets the original design objectives and performance requirements. The survey provides real-world measurements of coverage, signal quality and network performance, helping ensure that the deployed solution delivers the expected user experience.
Why Are Validation Surveys Important?
Even with careful planning and installation, real-world environments can introduce challenges that are difficult to predict during the design phase.
A validation survey confirms that wireless coverage, capacity and performance requirements have been met and identifies any areas that may require optimisation.
When Is A Validation Survey Performed?
Validation surveys are typically conducted after the wireless network has been fully installed and configured.
They are often used as the final stage of a wireless deployment project before the solution is handed over to the customer.
What Information Is Collected?
- Coverage Verification - Confirms that wireless coverage meets the design requirements.
- Signal Quality - Assesses signal strength and overall RF health.
- Roaming Performance - Evaluates how devices transition between access points.
- Application Performance - Verifies that business-critical applications perform as expected.
- Interference Analysis - Identifies potential RF interference sources affecting performance.
Benefits Of A Validation Survey
- Confirms Design Objectives - Verifies that the deployed network aligns with the original design requirements.
- Improves User Experience - Helps ensure users receive reliable and consistent connectivity.
- Identifies Optimisation Opportunities - Highlights areas where performance improvements may be beneficial.
- Provides Deployment Assurance - Gives confidence that the network is operating as intended.
Validation Surveys vs APoS Surveys
Although both methodologies involve collecting real-world wireless measurements, they are performed at different stages of a project.
APoS surveys are conducted before deployment to validate a proposed design, whereas validation surveys are performed after deployment to verify that the installed network meets the required performance objectives.
Key Points
- Validation surveys are performed after deployment.
- They verify that design objectives have been achieved.
- They assess real-world wireless performance.
- They help identify areas for optimisation.
