LTE modem

Note: For details regarding the modem API, please refer to nRF Connect SDK document and nRF91

AT Commands, Command Reference Guide document.

Key features of the LTE modem are:

• Complete modem with baseband and RF transceiver

• 3GPP release 13 compliant LTE categories:

• Cat-M1 (eMTC - enhanced machine type communication)

• Cat-NB1 (NB-IoT - narrowband internet of things (IoT))

• 3GPP release 14 compliant LTE categories:

• Cat-NB1 (NB-IoT)

• Cat-NB2 (NB-IoT)

• Power saving modes

• Supporting LTE bands from 700 MHz to 2.2 GHz through a single typical 50 Ω antenna pin.

• ANT antenna pin is DC grounded

• RX sensitivity: -108 dBm for Cat-M1 and -114 dBm for Cat-NB1 and Cat-NB2

• As defined in 3GPP conformance test specification TS 36.521-1

• 1.8 V MIPI RFFE (RF front-end) digital control interface and MAGPIO control interface for external RF

applications.

• An LTE modem internal ADC that is also used for some AT command interface services e.g. for battery

monitoring.

• 1.8 V UICC (universal integrated circuit card) interface, based on ISO/IEC 7816-3 and compliant with:

• ICC (ETSI TS 102 221)

• eUICC (ETSI TS 103 383)

Note: nRF9160 is able to run different modem FW builds that define the final modem feature set

in a specific nRF9160 based application.

Note: For details regarding the services provided by modem AT command interface, please refer to

nRF Connect SDK document and nRF91 AT Commands, Command Reference Guide document.

7.2 SIM card interface

LTE modem supports the UICC (universal integrated circuit card) interface.

Only the UICCs with the electrical interface specified in ISO/IEC 7816-3 are supported, meaning that the

UICCs with IC-USB, CLF or MMC interfaces are not supported.

The supported UICC/eUICC interface is compliant with:

• ETSI TS 102 221: Smart Cards; UICC-Terminal interface; Physical and logical characteristics

• ETSI TS 103 383: Smart Cards; Embedded UICC; Requirements Specification

The physical interface towards the eUICC is the same as towards the removable UICC.

Only the class C (supply voltage 1.8 V nominal) operation is supported. Support for the legacy class B

(supply voltage 3.0 V nominal) operation must be built with external components, including the external

power supply and the level shifters towards the LTE modem UICC interface.

LTE modem supports powering down the UICC during PSM and eDRX idle mode, when the UICC supports

this feature as specified in 3GPP TS 24.301. To reach the lowest total power consumption of the complete
