Verification of WLAN RF Design with Troubleshooting

The WLAN Deployment model ensures the right solution for your business and is a blueprint for deploying a Wi-Fi network. We can assist you in every step, from the start of the WLAN RF design to installation, validation, optimization, and auditing, to keep your wireless network healthy and ensure an optimal user experience for all wireless clients.

Troubleshooting (Layer 1)

WLAN troubleshooting starts at Layer 1. We highly recommend a Verification WLAN RF Design with Troubleshooting as the first step in the WLAN troubleshooting process.
The troubleshooting area can be a specific area or floor or the whole site. The analysis results from this WLAN site survey will give us a better insight if the reported problems are RF (layer-1) related.

When do you need this service?

  • You experience issues on your Wi-Fi network!

Prerequisites and Deliverables!

The following topics are the prerequisites and the deliverables for a Verification WLAN RF design (troubleshooting Layer 1).

Prerequisites:

  • Up to date floor plans (issue area)
  • Access to the issue area during the on-premises measurements
  • Make sure that the “AP Name” is broadcasted in the beacons of ALL configured SSIDs
  • List current TX-power settings of the active radios in the issue area.
  • During the onsite measurements, we need two wireless devices (with reported issues) for testing
  • list of reported cases out of the field (places where we can reproduce the problem)

Deliverables:

  • Interference Analyses (issue area)
    • Spectrum analysis (non-Wi-Fi interference)
    • Wi-Fi interference
  • RF Design Analyses (issue area)
    • Visual inspection (AP installation check-up)
    • Signal Strength, Primary Signal (heat maps based wireless devices with issues)
    • Signal Overlap, Secondary Signal (heat maps based wireless devices with issues)
    • Co-Channel Contention validation (heat maps based on same channel overlap
    • Wi-Fi network scan + Frame Captures (if applicable)
  • Recommendations & action plan (issue area)
    • Overall conclusion for all deliverables with recommendations and action plan for fine-tuning or remodeling of the RF environment (if applicable)

What can you expect from this service?

A detailed analyses report with the status of your Wi-Fi network’s current health recommendations with an action plan to optimize your RF environment (if applicable) for optimal performance and user experience of your wireless clients.

After completing this phase, our WLAN engineer will be available for a remote presentation of the gathered results and assist you in the further steps of the proposed action plan.
When wireless problems persist after implementing the action plan, the next step of the troubleshooting process is to start up a TAC with the Wi-Fi vendor and the vendor of the Wi-Fi devices/application, where we analyze the upper layers. Additional troubleshooting services can be required in the Optimization phase to tackle these specific issues.
