IoT Connectivity Modem

Making Life Smarter, Safer, and More Efficient

From low-power NB-IoT to high-performance LTE Cat.1, we provide the critical link between perception and network layers, driving the evolution of the Internet of Everything.

The Critical Link for Smart Industries

Wireless communication modules are the heartbeat of modern IoT. Whether for Smart Metering, Payment, or Asset Tracking, our modules aggregate device data and enable remote control. We empower industries—from industrial automation to smart homes—with reliable, scalable connectivity solutions.

Product Portfolio

NB-IoT Series

Designed for massive IoT connectivity with extremely low power consumption. Utilizing narrow bandwidth, our NB-IoT modules ensure deep indoor coverage and 6-8 years of battery life. Ideal for smart meters and sensors.

LTE Cat.1 Series

The perfect balance of speed, cost, and power. Our Cat.1 modules support medium-rate data transmission, making them indispensable for Wearables, POS Terminals, and Vehicle Telematics where real-time interaction is key.

Advanced & Custom

Cat.4 / Wi-Fi / Customization

Beyond standard modules. We offer high-speed Cat.4, Wi-Fi, and Bluetooth solutions.We provide full PCB design and software/hardware customization tailored to your specific project needs.

Product in detail

Multi-Protocol Support

Built for interoperability. Our modules support a wide range of protocols including TCP/UDP, MQTT, HTTP, and LWM2M, enabling seamless data reporting and interaction across diverse cloud platforms.

Energy Efficient Design

Forget about charging. Both NB-IoT and Cat.1 modules feature optimized Low Power Modes (PSM/eDRX), allowing devices to run efficiently on battery power for 6-8 years without external power source

Precision Positioning

Know where your assets are. Select modules feature integrated GPS/GNSS for precise tracking. For cost-sensitive applications, we also support LBS (Base Station) positioning for approximate location services.

Usage Scenarios

Smart Home

Enable device interconnection and remote control without relying on home Wi-Fi networks.

Smart Metering

Real-time data reporting for Water, Gas, and Electricity meters, eliminating manual reading labor.

Transport & Logistics

Real-time interaction with traffic signals and asset tracking for smarter, safer driving.

Financial Payment

High reliability and low latency for POS terminals and vending machines. Proven in high-concurrency commercial scenarios.
