1. Product Overview
JZX915 is a 4G full network, high-performance 4G DTU product developed by the Jizhuoxin team. This product relies on network platforms such as China Mobile, China Unicom, and China Telecom to achieve wireless data communication, overcoming the problem of short distance in traditional wireless communication. JZX915 is a virtual private data communication network that provides users with high-speed and transparent data transmission with high speed and low latency. Widely used in industries such as wireless data transmission, power industry, industrial control, agricultural irrigation, traffic management, environmental monitoring, centralized reading systems, and smart homes. The use of 4G DTU and other wireless modules from Techchip for network transmission can quickly solve various application scenarios and has great flexibility in networking forms.
