A hot standby radio can compare the amount of good packets received by radio A and radio B.

Default Differential Value (%) 20 %
RSSI Comparison
A hot standby radio can compare the level of RSSI received by radio A and radio B. A warning
alarm can be raised if the reported RSSI of the configured radio is lower than the reported RSSI
of the alternate radio by the specified margin (dB).
An offset should be used where the configured radio has an expected reduced RSSI, compared
to that of the alternate radio.
The offset can help detect RSSI compare alarms more accurately within a Hot standby
arrangement which utilises separate antennas for each radio.
The Margin and Offset are configured as a negative number

Base Health
The base health alarm is a warning indicator (alarm state can be either normal or warning),
which is subscribed to the radio’s alarm output. This can allow a user to monitor the base health
alarm state, and if/when the alarm state changes, a detailed review of the radio’s operating condition
can be performed.
