2 Introduction
Type1SC is Murata’s new LTE series for IoT applications. The module can be used as a wireless
communication front-end for wearable products, offering mobile communication features to an external
host CPU through its interfaces.
Note: NB1 will be supported in a future firmware release.

2.3 Tx Output Power
The LTE bands in the 1SC module meet the 3GPP spec for a Power Class 3 device (23 dBm).
2.4 Rx Sensitivity
The receive sensitivity of the module complies with the 3GPP spec and has a minimum value of -103 dBm.
2.5 Power Modes
The 1SC module has the following power modes
 LS: Provides very fast entry and recovery time and is mainly used for very short sleeps. It is used
for CDRX mode during the networking process.
 DS: Provides fast recovery and entry time and is mainly used during the IDRX networking mode.
 DH2: Provides medium entry and recovery time and is mainly used during the EDRX and IDRX
networking modes.
 DH1: Same as DH2, however IO logic is not retained.
 DH05: Provides long entry and recovery times and is mainly used for very long inactivity intervals
like PSM. The IO output values are retained in this mode.
 DH0: Same as DH05, however IO output values are not retained.
The device chooses the described power modes according to the networking state and the maximum
