(Note 1) RSSI Linearity has 10 measuring points (-90, -80 to 0dBm) from where getting the ideal linearity by way of mini square method, and
that each 10 measured spots should stay on within the range of ±1dB that can be obtained during the process of the measurement.
Also in the process of the measurement, RSSI dynamic range 90dB can be obtained at the same time.
