hi, we have deployed AH AP 130 and they are one in each room now there are so many major alerts regarding interference ? can someone guide please

The proper way to approach this is with an actual wireless design. But since you've already got all your APs in place, your left with having to adjust power and/or turn off radios to improve the RF environment. With turning off 2.4 GHz radios, you should probably try to understand RF loss between rooms to know which ones you can turn off and at what power level you'd need the others left on at to cover the rooms where the 2.4 GHz radio is not enabled.

Lowering power settings indirectly impacts data rate, but it is not a true 1-1 correlation. In fact, too much interference, ACI and/or CCI will impact the end user data rate as much or more as the higher the noise level in the environment, the lower the RSSI/SNR will actually be which is where the actual data rate (or MCS rate) is derived from.

thankyou for your response it really helps and given an plan to move forward. the problem is there are devices that still use 2.4 and we need to support it, if we lower the power settings would it not affect the speed and communication of client ?

one thing i was thinking is to shutdown the 1 ap and see if that help

Short answer - turn off some radios (especially on the 2.4 GHz side) and lower power settings of APs across the board.

Longer answer - A thesis could be written here. But spectrum is finite. And the available channels to choose from is limited. Unless you're able to get adequate channel separation from APs, you gain absolutely nothing from throwing an AP in "each room". As every AP that sits on like channels that is within earshot of each other is contending for access to the same spectrum.
