Code Word Error Ratio
Code Word Error Ratio provides an indication of wireless link
performance in the direction towards the unit where the
attribute is being monitored.
Data transmitted over the wireless link is organized into blocks
called Code Words. The size of the code word is fixed for a given
configuration of bandwidth. The transmitter applies Forward
Error Correction (FEC) to each Code Word and this allows the
receiver to correct certain Code Words which have been
received in error. If the receiver cannot correct a Code Word, it
will be counted as a Code Word Error. This may occur if the link
fades below the sensitivity threshold of the minimum
modulation.
The Code Word Error Ratio is the ratio of Code Words Errors to
the total number of Code Words received, calculated since the
last reset of the system counters.
