The COMFORT product supports the PSM (Power Saving Mode).
The main advantage of PSM mode is that it allows the product to operate for extended periods with
reduced power consumption.
The product periodically enters a prolonged inactive phase during which it is disconnected from
the network. During these periods, the sensor does not receive signals from the network and
does not send data. This significantly saves battery power as the product does not need to
maintain a continuous connection to the cellular network.
When the product needs to send data, it exits PSM mode and temporarily rejoins the network. It
establishes a connection with the base station and transmits the collected data.
Once the data is transmitted, the product returns to a low-power consumption state.
The user can configure the following PSM parameters via the NFC IoT Configurator application:
The period during which the product is reachable by the network to receive downlink data (T3324)
The deep sleep period during which the product remains attached to the network but is
unreachable (T3412)
📱
Go to the "CONFIGURATION" menu of the sensor => Select the "NETWORK" section =>
Configure the "T3412 Multiplier," "T3412 Value," "T3324 Multiplier" and "T3324 Value"
parameters => Apply the new configuration to the product via NFC.
Please note that while the product indicates the desired reachability period and the PSM period to the
network, these trigger values (T3324 and T3412) can be modified by the network during the
attachment procedure or when updating its location (TAU).
At any time, the user can check the trigger values (T3324 and T3412) on the NFC IoT Configurator
application.
