This article delves into how the deployment of Wi-Fi 6 mobile computer for warehouse and a customized industrial browser for SAP system achieved both warehouse network stability​ and operational accuracy in the complex warehouse environment of Lenovo's Tianjin Industrial Park. This case study provides a complete digital solution for industrial scenarios with high-density device connectivity.

User Background

In the Lenovo Smart Innovation Service Industrial Park in Tianjin, "green zero-carbon and intelligent manufacturing" is the main focus of the factory. It combines digital display, R&D, and production to present the greatest degree of zero-carbon intelligent manufacturing within Lenovo Group and the ICT sector as a whole. The park has Lenovo's independently developed high-performance intelligent motherboard and laptop production lines, as well as highly intelligent production workshops with over 110 smart scenarios. At the moment, it can produce one motherboard every ten seconds, totaling one million motherboards produced annually. With an annual output of over 3 million units, the laptop production line produces one laptop every nine seconds, achieving an automation rate of over sixty percent.

Challenges

The warehouse features dense human traffic, logistics, and shelving, resulting in a complex wireless environment. The large number of wireless terminals supporting business operations posed a challenge for traditional network solutions to cope with high-density device connectivity, leading to issues like slow speeds and frequent disconnections, which directly threatened production schedules. Furthermore, the diversity of international suppliers led to non-uniform material coding character sets, requiring the front-end business system to have robust compatibility.

l Network Instability Affects Work Efficiency: Unstable network connections and latency directly caused slow response times or even interruptions in SAP system operations on mobile terminals, severely impacting the efficiency and accuracy of warehouse tasks such as picking and put-away.

l Performance Bottleneck in High-Density Connectivity: In areas with dense device connections, the performance of traditional Wi-Fi networks deteriorated sharply, failing to ensure all terminals remained stable online simultaneously, creating an operational bottleneck.

The deployment of advanced Wi-Fi 6 mobile computer for warehouse and a customized industrial browser for SAP system​ led to a qualitative leap in the park's warehouse operations. Under high-density device connectivity, network upload/download speeds increased by 2-3 times, power consumption decreased by 25%, and crucially, warehouse network stability was achieved with seamless roaming, a packet loss rate as low as 1%, and a response time of only 3ms. Meanwhile, the industrial browser achieved perfect compatibility with the SAP system, supported multiple character sets, and optimized the interface layout, significantly improving user operation speed and accuracy. The overall project results exceeded customer expectations.

The core of the solution lies in the combination of hardware and software to precisely address the key pain points:

Hardware Upgrade

l Deploy AUTOID10 (Wi-Fi 6 Mobile Computer): Utilizing its Wi-Fi 6 Ready technology, it seamlessly integrated with the on-site wireless environment, significantly improving roaming capabilities. This fundamentally ensured warehouse network stability​ in complex environments and met the stringent demands of high-density device connectivity, guaranteeing that mobile terminals remained always online.

Software Customization

l Develop Seuic Industrial Browser: Customized specifically for the SAP system business scenarios in Lenovo's warehouse. This browser not only optimized the business interface layout but also integrated fourth-generation AI recognition technology and crucially resolved compatibility issues with various character sets, making this industrial browser for SAP system​ a reliable platform for precise and efficient operations.
