Automated guided vehicles (AGVs) are also used to transport goods or materials in Midea’s factory in Thailand. “The AGVs we use don’t need preset routes. Instead, they can plan, automate and analyse the real environment in real-time [to move around our factory safely],” Midea’s spokesperson Urban Zhao shares with the media at the Huawei Digital and Intelligence Apac Congress in Bangkok on April 29, 2024.
Using a set of cameras and lasers, those AGVs are constantly exchanging information and instructions with each other to avoid clashes. They can also detect humans and stop before contact, enabling a safer factory environment.
5G networks are the key enabler for its smart factories, says Zhao. 5G’s low latency and high bandwidth enable data from those robots and connected systems to be transmitted and analysed by artificial intelligence (AI) in real time to optimise operations and minimise unplanned downtime due to faulty machines.
Midea worked with Huawei and AIS (a telco in Thailand) to enable its 5G-enabled smart factory in Thailand.

This is not Midea’s first foray into smart manufacturing; its journey began in China. With the help of China Mobile and Huawei, Midea launched a fully 5G-connected factory in Jingzhou, Hubei, at the end of 2021. 5G is applied to all industrial production and business operations in that factory to enable smart manufacturing.
As a result, it takes only 15 seconds for the production line to make a single washing machine. The factory also doubled its direct delivery rate, halved its inventory and reduced labour costs by 30% per unit. It also improved its defect detection rate by 10%, thanks to 5G distributed massive MIMO (multiple-input, multiple-output) technology for intelligence-based quality inspection.
