LTE RSRQ to SINR

LTE Metrics including RSRP, RSRQ and SINR

LTE RSRQ and SINR
LTE Cellular Networks

Summary:

RSRQ and SINR are key metrics for LTE systems including CableFree LTE-A Infrastructure.  This page explains the technical differences.

In LTE – as any wireless system – the performance has a direct relationship with the RF conditions at the time.  To aid with performance analysis in LTE, it is typical to define some ranges of RF measurements that correspond to some typical RF conditions one might find themselves in.

The table below represents a good classification of RF conditions Vs LTE KPIs.  The source of this table is a vendor and has been complied during the RF tuning process in the field for an operator. Of course there are no rules as to how various RF conditions are classified, so different tables will exist but to a great extent you can expect them to align.
