SINR/RSSI values for good signal for EM7455

Hello All,

I am looking for following ideal values of SINR and .RSRQ for lte connection especially
EM74xx module

I found following ranges in AT reference manual but there was no mention about
good range.
(Reference Signal Receive Quality in dB) • -20 to -3
(Signal to Interference plus Noise Ratio) • -20 to +30

I get following values
One with active connection
response: '!GSTATUS:
Current Time: 39831 Temperature: 44
Reset Counter: 1 Mode: ONLINE
System mode: LTE PS state: Attached
LTE band: B7 LTE bw: 20 MHz
LTE Rx chan: 3050 LTE Tx chan: 21050
LTE CA state: NOT ASSIGNED
EMM state: Registered Normal Service
RRC state: RRC Idle
IMS reg state: No Srv

PCC RxM RSSI:  -56              RSRP (dBm):  -79
PCC RxD RSSI:  -57              RSRP (dBm):  -80
Tx Power:      --               TAC:         0001 (1)
RSRQ (dB):     -3.0             Cell ID:     01A2D001 (27447297)
