Custom Development of Communication Modules
Based on communication platforms such as 4G Cat.1, 5G, Bluetooth, LoRa, and NB-IoT, we provide custom development of module backplanes, transparent transmission boards, protocol conversion gateways, and edge communication motherboards, which can be used in conjunction with the five major industry terminals mentioned above.
I. Core Customization Capabilities:
- Module Adaptation: Customization of peripheral backplanes for mainstream 4G/5G, Bluetooth BLE, LoRa, and NB-IoT modules;
- Protocol Conversion: RS485/TTL to 4G/5G/Bluetooth conversion; custom transparent transmission for Modbus and MQTT;
- Antenna Matching: Debugging of PCB antennas, rubber rod antennas, and high-gain external antenna solutions;
- Low-Power Optimization: Sleep mode, scheduled wake-up, and power consumption tuning for battery-powered devices;
- Secure Transmission: Data encryption, device authentication, and whitelist binding to ensure IoT data security;
- Firmware Customization: Development of transparent transmission firmware, edge preprocessing firmware, local caching, and disconnection/reconnection strategies.
II. Success Story: Multi-Protocol Industrial Gateway Communication Board
A custom RS485-to-4G + Bluetooth dual-mode gateway motherboard that interfaces with sensors, PLCs, and water pump controllers to uniformly transmit data from multiple devices to the cloud via MQTT; Bluetooth supports on-site, wireless parameter debugging via smartphone, while 4G ensures stable remote data transmission. This solution is suitable for the unified network retrofitting of water management, energy, and agricultural/aquaculture equipment, significantly reducing customers’ costs for connecting multiple devices to the cloud.
