Thermal mitigation mechanism
After setting new values, the mitigation algorithm operates with them if a
power cycle or #REBOOT command is executed.
Thermal mitigation mechanism works like this:
- the whole temperature scale is divided into 5 states (zones).
- each measured temperature should belong to a state called the current
state.
Each state is defined by the following fields:
upper temperature boundary of the state. Values are in
Celsius degrees.
lower temperature boundary of the state. Values are in
Celsius degrees.
indicator that indicates if an action should be taken or not
in the current state.
action_info can be: none or mitigate, their values are shown in the table
below.
data throttling (reducing uplink baud rate)
TX back off (reducing MTPL - Max Tx Power Limit)
RF OFF. RX and TX circuits automatically disabled
(using +CFUN=4)
automatic shutdown. Module is powered OFF
There are five limitations on setting temperature and actions, in-order to
keep module safety.
- User is prohibited to set an action of "automatic shutdown" to 'operate
normal zone'.
- User is prohibited to set an action of "no mitigation" or "data throttling
"to "operate up zone".
