H3C Industrial Mobile Wireless Solution

1. Demands

Made in China 2025 clearly points out that intelligent manufacturing has become the new trend of China's modern advanced manufacturing industry. Under the background of national policy promotion and the transformation and upgrading of manufacturing technologies, China's intelligent manufacturing industry has developed rapidly. Data shows that the market size of China's intelligent manufacturing industry in 2019 was 1,777.5 billion yuan, with a growth rate of 18%. With the gradual improvement of technology and the continuous expansion of the industry, the market size will continue to grow. It is expected that the market size will exceed 2 trillion yuan in 2020, and its development will maintain growth. As an important part of the intelligent manufacturing industry, intelligent manufacturing equipment can significantly improve production efficiency and product manufacturing accuracy. It is a key element for the transformation and upgrading of the manufacturing industry. In November 2018, the National Bureau of Statistics released the Classification of Strategic Emerging Industries (2018), and the intelligent manufacturing equipment industry is listed as a strategic emerging industry. As the demographic dividend declines, it is imperative for intelligent manufacturing to improve production efficiency. In recent years, China's labor force population has been decreasing. In addition, the average annual wage has continued to rise, leading to an increase in labor costs. This forces companies to choose intelligent equipment to save labor costs. Thanks to technological advancement, the production cost of industrial robots continues to decrease, and the cost recovery period decreases year by year. The human-machine collaboration will become an important mode of industrial production.

Current problems faced by industrial mobile wireless

Difficult deployment

Industrial-grade deployment with a complex deployment environment requires fast and secure deployment

Mobile manufacturing equipment must be free of cable routing

Unstable network

Low latency: Devices such as AGVs move fast with requirements for high positioning accuracy and high response level for real-time interaction with the control system

Ultra-fast roaming. AGVs move quickly in warehouses and workshops and switch among multiple APs, during which packet loss may occur and cause the AGVs to stop.

Difficult O&M

The common wireless NIC is easy to be damaged due to the workshop environment and frequent moving

Network problems cause data endpoints and robots to stop to work, and traditional methods cannot locate the fault cause
