• Develop Android/iOS mobile apps to enable device networking, real-time monitoring, alarm notifications (such as vehicle abnormal vibration alerts), and voice control (compatible with 4G voice calls).

4. Network optimization and QoS guarantee

• For weak network environments (such as underground parking lots and remote mountainous areas), optimize the TCP/UDP protocol and retransmission mechanism to increase the data transmission success rate to over 99.5%.

• Support QoS priority configuration to ensure the real-time performance and reliability of critical services such as video streaming and emergency alarms.

5. Certification and compliance services

• Assist customers in completing global operator certifications (PTCRB, GCF), network access permits (CCC), and industry compliance testing (such as automotive-grade AEC-Q100).

Application scenarios

1. Intelligent Transportation

• Develop 4G in-vehicle OBD devices that upload vehicle location, fuel consumption, and fault code data to the cloud in real time, supporting fleet management and UBI car insurance pricing.

• Deploy 4G advertising screens in buses/taxis, and remotely update advertising content through the cloud to enhance operational efficiency.

2. Industrial Internet of Things

• Deploy 4G industrial routers in the factory to connect PLCs, sensors, and other devices, enabling real-time collection of production data and remote operation and maintenance.

• Monitor the status of the production line through 4G cameras, supporting AI visual inspection (such as defect recognition) and abnormal event alarms.

3. Smart Security

• Develop 4G solar-powered cameras for use in power-free scenarios such as forests and construction sites, supporting 4K video storage and motion detection alarm.

• Deploy 4G smart access control in the community, enabling contactless access and visitor management through facial recognition and 4G networking.

4. energy management

• Install 4G data collectors in photovoltaic power stations to monitor power generation efficiency and equipment status in real time, and support fault early warning and remote regulation.

• Develop 4G smart electricity meters that support remote meter reading, electricity usage analysis (such as peak and valley electricity optimization), and abnormal energy usage alarms.

5. healthcare

• Develop 4G wearable devices (such as emergency bracelets) that can upload patients' heart rate and blood pressure data in real-time to the hospital platform, and support emergency calls and location-based rescue.

Service Advantages

1. High-speed and stable communication

• Using LTE Cat.4 or higher modules, it supports downlink speeds of 150Mbps and uplink speeds of 50Mbps, meeting the real-time transmission requirements for 4K video and large data packets.

2. Global network compatibility

• The module supports global mainstream frequency bands (such as B1/B3/B8/B28), allowing customer products to seamlessly adapt to networks in markets such as China, Europe, and North America.

3. low-power design

• By utilizing PSM (Power Save Mode) and eDRX (Extended Discontinuous Reception) technologies, the device's battery life can be extended (for example, the battery life of a 4G camera can be up to 6 months).

4. High security guarantee

• Integrated with hardware-level encryption chips (such as SE security units), it supports the national cryptographic algorithms SM2/SM4, preventing data leakage and device cloning.

5. Rapid development and deployment

• Providing standardized development kits (SDKs) and reference designs can shorten the product launch cycle by over 40% and reduce customer R&D costs.

Case Introduction

Case 1: 4G vehicle monitoring project of a logistics enterprise
Wenge Technology has developed a 4G in-vehicle terminal for a global logistics enterprise, integrating GPS positioning, ADAS driving assistance, and 4G video transmission functions. The project covers over 100,000 trucks, enabling playback of driving trajectories, fatigue driving alerts, and real-time uploading of collision videos. It has helped the client reduce the accident rate by 35% and save over 50 million yuan in insurance costs annually.
