An enterprise needs an upgrade to 802.11ac. Users run applications such as Web, email, voice, and video. The architect needs to conduct an active site survey to plan 802.11ac AP locations. The noise floor is about -90 dBm across the site.
Based on Aruba best practices, what is the minimum acceptable signal that the architect should look for to determine the test AP range?
The minimum acceptable signal strength that the architect should look for when planning 802.11ac AP locations is -65 dBm in the 5 GHz band. This is based on best practices which suggest that for optimal performance and coverage, especially for applications such as voice and video which are more demanding, a stronger signal in the 5 GHz band is preferable. The 5 GHz band provides wider channels and lesser interference as compared to the 2.4 GHz band, making it more suitable for high-throughput applications.
The Answer is C. -65dBm should be the minimum RSSI value for the coverage area. And you should always plan for 5Ghz and not 2.4Ghz as best practice.
