WWAN/5/WWAN_SINR_NORMAL: The LTE signal of interface [interface-name] become normal, SINR= [SINR] dB, RSRP= [RSRP] dBm, RSRQ= [RSRQ] dB.


Only V200R007C00 supports this log.


The strength of LTE signals received by a cellular interface became normal.


Parameter Name Parameter Meaning
[interface-name] Cellular interface name.
[SINR] Signal to interference plus noise ratio (SINR).
[RSRP] Reference signal received power (RSRP).
[RSRQ] Reference signal received quality (RSRQ).

Possible Causes

On an LTE network, if the strength of received LTE signals is greater than the SINR threshold 10 consecutive times, and the signal strength becomes normal, the device records this log.

By default, the SINR threshold used to determine the LTE signal strength is 10 dB.
