SINR/SNR – signal-to-noise ratio of given signal. RSRP – The average power received from a single Reference signal, і It typical range is around -44dbm (Good) to -140dbm (bad). RSRQ – Indicates quality of the received signal, і його range is typically -19.5dB(bad) to -3dB (good).

Addition of RSSI and SNR must be considered to evaluate the radio link quality. RSSI is the signal level reception. SNR is the signal noise rate and give indication on the ambiant noise level.

Signal to Interference plus Noise Ratio (SINR) SINR is a measurement of the interfering noise на основі actual signal being received by the 4G LTE modem. У випадку з SINR, він повинен бути позитивним номером і великим числом є від 0 до кінця свого SINR.
