How to check poor coverage in the 5GHz and 6GHz bands?

Higher frequency radio waves, like those used in the 5GHz and 6GHz bands, have shorter wavelengths. Shorter wavelengths have a harder time penetrating solid objects such as walls, floors, and furniture. This results in reduced coverage and signal strength as you move away from the wireless access point.

To effectively diagnose coverage problems, here are some suggestions:

• Conduct a Site Survey: perform a site survey can include a detailed layout or photos of the environment. Measure the signal strength at various points and determine where it degrades over distance.
  
• AP Comparison: Compare the AP you decide to deploy with other APs by considering the model and antenna capabilities. Select suitable one that can cover your area or add more APs to provide enough coverage.
  
• Band and Channel Width Impact: The band (frequency) used can affect the power output due to regulations. A narrower channel width generally results in higher power output. Optimize these settings based on your specific environment for better coverage.
  

Recommendation: Try changing the channel and bandwidth settings to avoid interference from other non-DFS channels. If the problem persists, comparing detailed specifications of the current APs being used and those of any competitor APs may offer additional insights.
