Recently we have been facing high noise floor issue(-110 or -70 in ZF2741) and Airtime issue (above 70% even zero clients connected).

We have tried and installed AP shield,Separated neighbors Radio and AP with long distance,But we have failed to reduce airtime and noise issue.

Kindly give guidelines to reduce airtime and noise issue.

Is BTS 4G network will cause high interference?

Do you have a laptop with an RF monitoring application? It sounds like local RF interferors near your APs.

Hi,

You have to check:
- what kind of interference you are dealing with: is it of wifi origin - 802.11n, like other SSIDs in the area- or non-wifi, like a microwave oven etc.)
- on which radio it is present (2.4GHz most likely or 5GHz)
- on which channel(s)

If it appears only on a specific channel you could stop using this channel and/or adjacent channels for your AP's config.

In terms of tools:

- Wi-Spy+ Chanalyzer from Metageek is a spectrum analyzer that will show you the wireless environment (both wifi and non-wifi activity)

- wifi Explorer application will show you any wifi activity around you and the channel utilization

- you could also try Spectrum Analysis feature on the Ruckus APs managed by a controller
