To ensure proper product functioning and autonomy, Adeunis strongly recommends:
Selecting an operator that supports PSM mode on its own network. Note that in the case of a
roaming connection, Adeunis recommends verifying that PSM mode is also guaranteed on other
operator networks. For more information on PSM mode, please refer to the dedicated section
Selecting the technology (NB-IoT or LTE-Cat-M1) that the product will use to connect to the
cellular network
Limiting the number of frequency bands used by the product to connect to the cellular network
(for example, in France, only band 20 is used by operators)
Favoring LwM2M servers with a connection ID
Favoring the use of "PUSH" mode for product-server communication
Limiting the number of OBSERVATIONS in the case of using "OBSERVE" mode
3.1. Battery Life Estimates in "OBSERVE" Mode
3.1.1 NB-IoT Network
The two battery life tables below have been estimated based on a product configured to communicate
with an LwM2M server in "OBSERVE" mode and connected to an NB-IoT network with PSM (Power
Saving Mode) support. Please note that the product's battery life may vary depending on the selected
operator.
