Performance Page
This page provides statistical information about the performance of the system in relation to the
integrity of the user data and the RF link.
Figure 31 Radio Performance page
• The Current BER field indicates the current bit error rate of the link. If the link is operating
perfectly, this should indicate zero. Generally, the link should remain at a BER less than 1x10
-6
(one bit out of every million bits errored). This is the threshold performance specification and the
standard to which the link was engineered. However, radio links can and are affected by weather,
interference, and other external sources and will occasionally have a higher error rate. A link
remains operational unless the BER exceeds 1x10
-3
(1 bit out of every hundred bits errored).
Consult the link design engineer for an understanding of the predicted error rate of the radio link as
it has been designed.
Many applications are unaffected by bit errors. However, if the link operator is providing a service
guarantee, this value may need to be monitored or examined in cases of service issues. The
behavior of BER in relation to other alarms or measurements and external events can be very
helpful in troubleshooting activities.
• Errored Seconds (ES) indicates the total number of seconds that occurred where there was at least
one bit error since the last time that the radio statistics counter was reset. Generally, ES are not a
significant concern, so long as they are not continuous or above the anticipated performance based
on the original link engineering goals. If ES are continuous or at a high rate, this is normally an
indication of poor link performance due to poor RSL or interference, or severe impact by weather
or other environmental factors. However, similar to the performance factors previously listed, ES
can and will occur in any radio link. Once again, consult the link engineer to determine the original
