Verizon showcased the integration of 5G connectivity, specifically over Wi-Fi, for its newly introduced autonomous mobile robots navigating factory floors. During a demonstration at Verizon’s 5G day in Basking Ridge, N.J., Bill Stafford, associate director of robotics in the emerging technology solutions group at Verizon, emphasized the advantage of cellular technology over Wi-Fi for mobile devices. He noted the inherent limitations of Wi-Fi in seamlessly handing over between access points, underscoring the necessity of a reliable 5G connection for autonomous mobile robots to perform tasks effectively.
Stafford highlighted Verizon’s partnerships with clients in the auto manufacturing industry, where thousands of robots are deployed on factory floors. He explained that as the number of autonomous devices connected to Wi-Fi networks increases, there is a noticeable decline in Wi-Fi capabilities, prompting the need for a more robust connectivity solution like 5G.
Security emerged as a significant concern, with Stafford mentioning the provisioning of SIM cards for specific devices. This approach allows warehouses to control network access, restricting it to authorized devices only, unlike conventional Wi-Fi networks that offer more open access.
Stafford emphasized the importance of 5G for robots due to its reduced network latency and increased speed. Low latency is crucial, particularly for tasks involving autonomous robots, where interruptions or delays can disrupt operations.
Moreover, deploying 5G in factories can lead to a reduction in infrastructure requirements compared to Wi-Fi. Stafford cited an example where a single $12,000 5G cellular node could cover the same area as approximately 30 Wi-Fi nodes, demonstrating the cost-effectiveness and efficiency of 5G deployment.
Similar motivations were shared by Ericsson’s Cradlepoint, which highlighted Toyota’s decision to replace Wi-Fi with private 5G in a forklift factory in the United States. They pointed out the inconsistent performance of Wi-Fi within the factory premises and its lack of coverage outside, further advocating for the adoption of 5G technology in industrial settings.
