VI. Antenna Specifications
The antenna interface model of SIM7600G-H-M2 module is IPEX 4th generation interface.
| Antenna Interface | Function | Remarks |
|---|---|---|
| MAIN | Main antenna, must be connected | LTE/4G, 3G, 2G transmit + receive main path, responsible for core services such as network registration, data transmission/reception, calls, etc. Must be connected, otherwise the module cannot access the network or register with base stations |
| AUX | Diversity antenna, recommended | LTE/4G receive diversity (receive only, no transmit), forms diversity reception with MAIN to improve sensitivity, speed and stability under weak signals. Spatial isolation from MAIN >5cm. |
| GNSS | Positioning antenna, connect as needed | Dedicated to satellite positioning such as GPS, Beidou, GLONASS, Galileo, providing positioning information such as latitude/longitude, speed, time. Not required if positioning is not needed. |
