Rssi value range for different types of beacons?

I need to know that at particular distance (for example 5m), the rssi value for Location beacons ,proximity beacons and stickers are the same

For Location and Proximity Beacons, you can use the Utils.computeAccuracy method to “normalize” the RSSI into something that very roughly corresponds to the distance between the beacon and the device.

rssi value almost equal for all beacons but getting different accuracy value. and i need that rssi value depends on which factor
