Many IoT applications require both wireless data transmission and location tracking — from asset monitoring and vehicle tracking to wearable devices and smart city infrastructure. This project required a compact, low-power module that integrates GPRS communication and GPS positioning into a single solution.
Key Hardware Requirements:
Dual-Function Integration: GPRS communication + GPS positioning on a single board
High Sensitivity: Reliable GPS lock in urban canyons and challenging environments
Low Power Consumption: Extended battery life for portable tracking devices
Industrial-Grade Reliability: Wide operating temperature range for outdoor use
Compact Form Factor: Small footprint for integration into space-constrained devices
Global Compatibility: Quad-band GSM/GPRS for worldwide deployment
We designed a compact industrial-grade GPRS+GPS combo module PCBA integrating a quad-band GSM/GPRS modem with a high-sensitivity GPS receiver on a single board. The module provides seamless wireless data transmission and precise location tracking for IoT and M2M applications.
Key design features:
RF Integration & Isolation
Carefully designed PCB layout to minimize interference between GPRS (850/900/1800/1900MHz) and GPS (1.5GHz) RF paths
Optimized antenna matching and placement for both GPRS and GPS signals
Shielded RF sections to prevent desensitization of the GPS receiver during GPRS transmission
IPEX antenna connectors for both GPRS and GPS antennas
High-Performance GPS
56-channel GPS receiver with -162dBm sensitivity
2.5m horizontal positioning accuracy
Cold start: 26s first fix, Hot start: 1s
AGPS support for faster TTFF
Support for periodic GPS data reporting (timed upload)
Communication & Control
Quad-band GSM/GPRS (850/900/1800/1900MHz)
GPRS Class 12 (85.6kbps up/down)
UART serial interface for data communication
Multiple GPIOs for remote control and sensor interfacing
Built-in MQTT protocol support
OTA firmware update capability
Low-Power Design
Standby current: Less than 2.0mA
Sleep mode for extended battery life
Optimized power management for battery-powered applications
Wide voltage input range (3.3V-4.5V, typical 3.8V)
PCB Manufacturing
Industrial-grade components for -40°C to +85°C operation
SMT-friendly design for automated assembly
Compact form factor optimized for space-constrained applications
CCC certified
