1. Industrial Wireless Router Chips: The "Heart" Determining Product Performance
The core functions of an industrial wireless router include data transmission, protocol conversion, edge computing, and security protection, among others. The realization of these functions highly depends on the performance of the chips. Specifically, the chip solution for an industrial wireless router typically comprises the following key modules:
Main Control Chip (CPU): Responsible for core functions such as data processing, protocol parsing, and task scheduling. Its performance directly affects the router's throughput, latency, and concurrent connection capabilities.
Communication Chips: Including 4G/5G baseband chips, Wi-Fi chips, LoRa chips, etc., these determine the data transmission rate, coverage range, and anti-interference capabilities.
Security Chips: Provide security functions such as data encryption, identity authentication, and access control to safeguard industrial networks from attacks.
Interface Chips: Support industrial interfaces like RS232/RS485, DI/DO, and Ethernet, enabling seamless integration with sensors, PLCs, and other devices.
In industrial scenarios, chip reliability is of paramount importance. Industrial environments often feature extreme conditions such as high and low temperatures, electromagnetic interference, and vibrations. Chips must possess wide-temperature operation capabilities, anti-interference designs, and redundant backup mechanisms to ensure long-term stable operation.
As a leading brand in the IIoT field, PUSR is extremely selective in choosing chip solutions for its industrial wireless router products (such as the USR-G809s).
