The SIM5320E is a versatile HSPA+/WCDMA/GSM/GPRS/EDGE and GPS module designed for high-speed data communication and precise positioning. Since it supports 3G (HSPA), it is a reliable choice for regions where 2G networks are being phased out. It is commonly used in vehicle tracking, fleet management, and industrial IoT applications that require both fast data throughput and GPS location services.

Specifications

• Frequency Bands:
  • 3G (WCDMA/HSPA): 900/2100MHz
  • 2G (GSM/GPRS/EDGE): 850/900/1800/1900MHz
• Data Rates: HSDPA up to 3.6Mbps (Downlink), WCDMA up to 384Kbps (Uplink)
• GPS: Integrated 16-channel GPS/A-GPS receiver
• Operating Voltage: 3.4V to 4.2V (Typical 3.8V; 5V if using a breakout board with regulator)
• Interfaces: UART (AT Commands), USB 2.0, I2C, GPIO, ADC
• SIM Interface: Standard 1.8V / 3.0V SIM card

Features

• High-Speed Connectivity: Provides significantly faster data transfer than standard 2G modules (like the SIM800L), making it suitable for sending images, large log files, or streaming simple data.
• Integrated GPS/GLONASS: Supports high-sensitivity GPS for real-time tracking. It includes A-GPS support to speed up the Time-To-First-Fix (TTFF).
• Multimedia Capabilities: Features embedded TCP/IP, FTP, and HTTP stacks. It also supports SMS and Voice calls (via external audio interface).
• Low Power Consumption: Designed with power-saving modes, making it viable for battery-powered remote monitoring stations.
• Global Positioning: The "E" version is specifically optimized for European and Asian frequency bands, ensuring stable 3G connectivity in those regions.

Antenna Connections

• GSM/3G Antenna: Required for cellular network signal.
• GPS Antenna: Passive or active antennas can be used (active antennas typically provide better performance in urban environments).

Common Applications

• Vehicle Tracking & Security: Real-time GPS tracking with high-speed data reporting.
• Remote Sensors: Sending sensor data via HTTP/MQTT to cloud platforms.
• Industrial Gateways: Providing a 3G internet bridge for remote machinery.
• SMS/Call Notifications: Automated emergency alerts or remote control of industrial equipment via SMS.

Usage Tips

• Power Requirements: The module can draw peak currents up to 2A during network transmission. Ensure your power supply (Li-Po battery or DC adapter) can handle these spikes to avoid brownouts or reset loops.
• Antenna Placement: For best GPS performance, the GPS antenna should have a clear, unobstructed view of the sky.
