WWAN/5/WWAN_SINR_WEAK

WWAN/5/WWAN_SINR_WEAK

Message

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

NOTE:

Only V200R007C00 supports this log.

Description

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

Parameters

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 not greater than the SINR threshold 10 consecutive times, and the signal strength becomes weak, the device records this log.

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

Procedure

  1. Check whether the network environment is normal.
  2. Check whether the antenna is properly connected.
