1 Introduction
1.1 Overview
This document describes how to get network cell info using SIMCOM module network AT interface. The detail describe of Network AT INTERFACE please see document AT Commands Set. And this document mainly give out the AT command example to suggest how to use the interface.
1.2 References
The present document is based on the following documents:
[1] SIMCOM_SIM7100_ATC_EN_V0.01.doc.
1.3 Terms and Abbreviations

2 Command Example
2.1 Module Initialization
When the module is in online state, it will camp on someone network if existed; If SIM card inserted and everything is ok, the module will get full service; If no SIM card inserted, the module will get limited service; No matter in full service or limited service state, the network AT COMMANDS can get the system cell info.
2.2 Command Description
AT+CNSMOD Current system mode When module camped on someone network, or changed from one network to another, AT+CNSMOD can get the current system mode; If special preferred system mode to be set to phone, please using AT+CNMP
AT+CNMP Preferred system mode
Regularly this command is to set the preferred system mode;
AT+MONI GSM cell info If the module camped on GSM cell, just like +CNSMOD=1, the command can get serving cell info, e.g., mcc, mnc, arfcn, bsic, cell id, lac, c1-c2... If adjacent cell existed, this command can also get the neighbor cell info, e.g., arfcn, cell id, lac, rxlev, c1-c2…
AT+CRUS WCDMA cell set info If the module camped on WCDMA cell, just like +CNSMOD=4, the command can get active set info, e.g., psc, ssc, cell id, freq, ecio, rscp... If sync neighbor set not empty, the command can get sync neighbor set info, e.g. psc, ssc, freq, ecio, rscp… If async neighbor set not empty, the command can get async neighbor set info, e.g. psc, ssc, freq, ecio, rscp…
AT+CNLSA Network limited service allowed
Most network operation commands are only allowed in full service state, and CNLSA value is 0; If the CNLSA value is set to 1, the most network operation commands can also work in limited service state.
AT+CMGSI GSM/WCDMA/LTE/ CDMA/TDSCDMA serving cell info
If the module camped on LTE cell, just like +CNSMOD=8, the command can get serving cell info, e.g., cell id, freq, tx power, rx power… This command is also supported with GSM/WCDMA/CDMA/TDSCDMA mode, and returns the related cell info.
AT+CMGRMI Gets the neighbor measurement
If the module camped on LTE cell, just like +CNSMOD=8, the command can get serving cell info and neighbor cell info for the
