How to classify rssi of beacon as High, medium, low , poor range with +4dBm TX power

[bivay]

I am using NRF52832 as Beacon, I want to classify the RSSI as High, Medium, Low, and Poor based on RSSI.

I am using SDK14.2.0 for Beacon and Gateway.

And using +4dBm Tx power of Beacon.

Thank You

Hi,

This is something you would need to classify yourself depending on what you consider to be High, Medium, Low, and Poor. For instance you can measure RSSI at 0.5m and set that will be High<->Medium, then measure at 2m  and set that will be Medium<->Low, and measure at 8m and  and set that will be Low<->Poor.

Best regards,
Kenneth

Is there any reference for this.

Sorry no. You would likely need to average the values, since I expect they will vary much.

I will use kalman filter for it. But after that wants to give that rssi value a tag of  Range which are suppose to be High, Range, Medium Range, Low Range and Poor Range. For example lets say rssi greater than -50 is consider as High Range, -50 to -70 is consider and Meduim Range, -70 to -95 cnsider as low range and less than -95 is consider as poor. But I need some refrence to calssify this range limits for +4dBm Tx Power.
