Survey Types

1 – Predictive Site Survey

Often misunderstood, this type of site survey offers cost and time effectiveness as well as being extremely accurate. Using both RF and specialized algorithms, a predictive site survey simulates RF in your specific environment.

From our experience this software has become very accurate and gives you an incredible view of their environment. When combined with an experienced wifi service provider, a successful design, even in high-density areas, can be achieved. The key to a good predictive survey is to have as much information as possible; we recommend using floor plans and building blue prints.

2 – Physical Site Survey (Active)

This type is highly recommended for more complex wireless objectives. This usually encompasses applications that roam from AP to AP and also tend to be latency sensitive. For example, RTLS in hospitals, wireless video surveillance and multi-media over wireless.

Typically with an on-site survey we use the predictive results to test them against the wireless design to prove that design in the real world, paying close attention to interference or noise. It’s important to simulate the applications that will be running on the network to make sure they work seamlessly.

3 – AP on a Stick

Using an AP on a Stick as an on site survey to simulate the performance of an AP in the actual environment taking into account the environmental impact on performance and coverage areas.

4 – Passive

Used to collect RF data from all of the access points in a given area, these types of surveys are good for validating your design requirements. It allows us to plot WiFi heatmaps giving you a nice view of where your coverage spans and where there are holes at different levels.

Some of the main design elements a passive survey can help validate are primary and secondary RSSI, Interference (noise), SNR and co-channel interference.

5 – Post Validation

A wireless network design can be great on paper but real success is when it performs exactly as it should for what it was designed to support. A post validation site survey makes sure your new network is performing as it was designed to, using the requirements you established at the beginning of your design.

Testing and measuring every detail guarantees you can support your applications and processes successfully with your new network. Some areas to take a closer look at are: data rates, device to radio ratios, jitter, latency and QoS, high density areas and co-channel interference as well as other RF characteristics.

You can even use an application performance test to test your network from the application side of things for a unique view of your networks performance.

It’s important to understand the various types of site-surveys; to know when each is needed, and to make sure your next wireless network is successful. In doing so we're sure your stress levels will without a doubt go down.


GPS has the ability to not only design but implement the design solution in any environment.  Installation can include not only correctly mounting of your wireless devices but also the infrastructure to support the connectivity to the controller.  GPS provides the products and installation solutions for UTP, STP and Optical Fiber installations from the network backbone to the device location.


With a properly designed and installed network there are still issues that arise that prevent a wireless solution from functioning to its full extent.  GPS has the ability to troubleshoot performance and coverage issues from the controller to the device.  Troubleshooting could be a s simple as a need to reset a device to replacing a nonperforming access point or controller.  GPS provides solutions to determine and service system issues.

The pros and cons

Which wireless LAN site survey method you use depends on the type of project your company is working on. Some of the key considerations between active and predictive surveys include:

 Active (live) surveyPredictive survey
Survey EffortPotentially higherPotentially lower
Access Point PlacementExact locations chosenFinal locations may need to be moved
Wireless CoverageMeasured and knownEstimated: May require more APs
Wireless PerformanceMeasured and knownEstimated: May require more APs
Cabling and EquipmentTypically accurateMay require cables to be added or relocated
InstallationUsually a one-time eventMay require moving APs around or adding more APs after installation
