Radio interference

Hi,

I'm using an evaluation board with nRF52811 for a smart home device project, which the user can see the distance between his smartphone and the peripheral, calculated by the Tx Power and RSSI.

During the connection test, we've found many factors could affect the radio transmission and receive dramatically, such as the structure/layout of the building and room, other Bluetooth or Wi-Fi devices nearby.

To reduce and compensate the  environment interference, we need to collect a lot of data.

My question is, does Nordic has published any test data about interference in different circumstances? Or is there any guides for developers to conduct their own experiments to optimize the distance calculation?

Any suggestion is welcomed.

Thank you very much.
