How Far Can RS485 Transmit? Understanding the Relationship Between Baud Rate and Distance
When designing an RS485 communication network, one of the most common and practical questions engineers face is how far a signal can travel while maintaining stable and reliable communication. The relationship between RS485 baud rate and transmission distance is a key consideration in industrial automation, energy management, and control systems. Pushing data rates too high over long cable runs often leads to signal distortion, intermittent communication, or complete data loss.

CAN vs Serial Communication — A Complete Analysis
In embedded systems, industrial automation, and automotive electronics, communication buses function as the “nervous system” that links various electronic control units. Among them, CAN Bus (Controller Area Network) and Serial Communication (commonly referring to UART, RS232, or RS485) are two of the most widely used wired communication technologies. Although both transmit data serially, they differ greatly in architecture, characteristics, and application scenarios.

Understanding the Need for QoS in Network Traffic Management
In today’s highly interconnected digital age, networks have become the lifeline for enterprise operations and daily communication. However, as applications such as video conferencing, real-time audio and video, and IoT data streaming place increasingly stringent demands on network latency, jitter, and packet loss rates, limited bandwidth resources often prove insufficient. Quality of Service (QoS) has emerged in this context — like an intelligent traffic control system, it can identify and prioritize the transmission quality of critical business traffic in complex network environments, thereby ensuring clear and uninterrupted voice communication, smooth and uninterrupted video streaming, and real-time, unlost control signals. Whether in enterprise communications or industrial IoT scenarios, QoS plays an irreplaceable role.
