{{Short description|Metric used in LTE networks}} {{Single source|date=January 2024}} '''Block Error Rate''' (BLER) is a ratio of the number of erroneous blocks to the total number of blocks transmitted on a digital circuit.
It is used in measuring the error rate when extracting data frames from a Compact Disc (CD). The BLER measurement is often used as a quality control measure with regard to how well audio is retained on a compact disc over time.
BLER is also used for W-CDMA performance requirements tests (demodulation tests in multipath conditions, etc.). BLER is measured after channel de-interleaving and decoding by evaluating the Cyclic Redundancy Check (CRC) on each transport block.
Block Error Rate (BLER) is used in LTE/4G technology to determine the in-sync or out-of-sync indication during radio link monitoring (RLM). Normal BLER is 2% for an in-sync condition and 10% for an out-of-sync condition.<ref>{{cite web | url = http://rfmw.em.keysight.com/rfcomms/refdocs/wcdma/wcdma_meas_wblerror_desc.html | title = Block Error Ratio (BLER) Measurement Description | access-date=23 December 2015 | date = February 28, 2014 }}</ref>
