Selection Guide for Routers in Large-Scale Industrial Projects: Precise Matching of High-Performance Devices with Scenario Requirements
In the blast furnace control system of a certain steel group, router delays exceeding standards led to lagging temperature control of the hot blast stove, resulting in a daily production loss of over 200 tons. In a new energy vehicle factory, protocol compatibility issues with the router caused interruptions in data exchange between AGV trolleys and the MES system, leading to the shutdown of three production lines. These cases reveal the core pain points of large-scale industrial projects: how to select, with a budget of millions, a high-performance industrial LTE router that can support concurrent connections from thousands of devices and adapt to extreme environments ranging from -40℃ to 75℃? This article will provide a practical selection framework for large-scale industrial projects from three dimensions: hierarchical scenario requirements, performance parameter analysis, and comparison of typical solutions. Submit an inquiry for consultation to receive a customized model list and deployment plan.

1. Hierarchical Scenario Requirements for Large-Scale Industrial Projects: From "Single-Point Control" to "Global Collaboration"
   1.1 Basic Control Layer: Rigid Demand for Microsecond-Level Delays
   In core equipment control scenarios such as steel rolling mills and forging presses, industrial LTE routers must meet the following indicators:
   Delay Control: PLC communication delays must be below 10ms; otherwise, deviations in steel plate thickness may exceed standards. Field tests on a certain automotive steel plate production line showed that the USR-G806w achieved an average delay of only 3.2ms when fully loaded with 200 PLC devices, an 80% improvement over traditional equipment.
   Jitter Suppression: Delay fluctuations must be controlled within ±1ms. By utilizing the QoS flow control function of the USR-G806w, a wind farm elevated the priority of data streams for its pitch control system, reducing control command jitter from 5ms to 0.8ms.
   Protocol Compatibility: Support for industrial protocols such as Modbus TCP, Profinet, and EtherCAT is required. The USR-G806w features a built-in protocol conversion engine that can automatically recognize over 300 industrial protocols, reducing the need for protocol conversion devices.

1.2 Real-Time Monitoring Layer: Efficient Transmission of Multimodal Data
In scenarios such as machine vision quality inspection and equipment predictive maintenance, routers must address the following challenges:
Bandwidth Management: A single 8K video stream requires 50Mbps bandwidth, with a 40% redundancy reserved for concurrent operation of multiple cameras. A certain photovoltaic power plant achieved seamless transmission of 16 8K video streams using the dual Gigabit Ethernet ports of the USR-G806w.
Wireless Coverage: Open factory areas require coverage within a 2-kilometer radius, while environments with multiple obstacles necessitate support for Wi-Fi 6E. The 5GHz band of the USR-G806w can penetrate five layers of concrete walls while maintaining signal strength in wall-penetration mode.
Mobility Support: AGV trolleys require seamless AP switching during high-speed movement. The Wi-Fi roaming function of the USR-G806w enables switching delays below 30ms for trolleys moving at 150 meters per minute.

1.3 Big Data Analytics Layer: Edge Computing and Cloud Collaboration
In scenarios such as equipment health management and production optimization, routers must possess:
Local Storage: Support for TF card or USB3.0 expansion for storing historical data. The USR-G806w's USR Cloud platform can automatically back up device logs, with a monthly storage capacity of 50GB per device.
Edge Computing: Built-in lightweight AI modules for local processing of simple analytical tasks. A wind farm improved the preprocessing efficiency of wind turbine vibration data by 60% using the edge computing capabilities of the USR-G806w.
Cloud Integration: Support for protocols such as MQTT, HTTP, and OPC UA for seamless integration with platforms like Alibaba Cloud and Tencent Cloud. The USR-G806w's USR Cloud platform provides a visual dashboard displaying real-time indicators such as device online rates and data transmission volumes.

1. Analysis of Core Parameters for High-Performance Routers: From "Theoretical Indicators" to "Practical Efficiency"
   2.1 Processor Performance: Determines Concurrent Capacity and Stability
   Clock Speed and Core Count: Large-scale industrial projects require processors with four or more cores and a clock speed of ≥1.5GHz. The USR-G806w adopts a Qualcomm QCS610 chip with a quad-core A53 architecture and a clock speed of 1.8GHz, supporting concurrent connections from 500 devices.
   Memory Capacity: Devices with ≥512MB DDR4 memory are recommended. The USR-G806w is configured with 1GB of memory, with a memory usage rate below 40% during full-load operation.
   Forwarding Capacity: A forwarding rate of ≥100,000 pps (packets per second) is required. The USR-G806w achieved a measured forwarding rate of 120,000 pps, a 30% improvement over similar products.
   2.2 Network Interface Configuration: Adapts to Complex Topological Structures
   Wired Interfaces: Provide ≥4 Gigabit Ethernet ports (2WAN+2LAN) with support for link aggregation. The USR-G806w is configured with 2× Gigabit Ethernet ports (1WAN+1LAN) and 1× RS485 serial port, with the capability to expand to six ports via expansion modules.
   Wireless Interfaces: Support for dual-band Wi-Fi 6 (2.4GHz/5GHz) with a transmit power of ≥20dBm is required. The USR-G806w employs dual FEM chips, boosting transmit power to 23dBm and achieving a coverage radius of 300 meters.
   4G/5G Modules: Support for all frequency bands of the three major operators with a downlink rate of ≥300Mbps is required. The USR-G806w supports the 5G NR Sub-6GHz band, achieving a measured downlink rate of 380Mbps.
   2.3 Environmental Adaptability: Responds to Extreme Industrial Scenarios
   Protection Rating: An IP65 rating or higher for dust and water resistance is required. The USR-G806w has passed IP30 certification and can operate stably in dusty environments.
   Temperature Range: Adaptability to environments ranging from -40℃ to 75℃ is required. In low-temperature tests at -40℃, the USR-G806w achieved a startup time of only 15 seconds; in high-temperature tests at 75℃, it operated continuously for 72 hours without failure.
   Anti-Interference Capability: Passing EMC Level III certification to suppress electromagnetic interference is required. The USR-G806w exhibited a signal interference rate below 0.5% in environments densely populated with frequency converters.
