In the crucial domains of hospitals, utilities and factories, IT networks rely heavily on Ethernet technology. Recognizing the growing demand for improved mobility within these networks, a critical need has emerged. While robust mobility solutions have been successfully developed for cellular networks, traditionally based on IP technology, a transformative feature has been introduced by 3GPP, known as 5GLAN. The 5GLAN feature represents a significant leap forward, enabling the utilization of native Ethernet frames within cellular networks. This innovative approach not only enhances the mobility of devices within local area networks (LANs) but also does so in an exceptionally cost-efficient manner, making it a powerful tool for delivering robust mobility functionality. Exploring use cases that have been successfully executed using the groundbreaking 5GLAN technology and a deep dive into the technological intricacies, shedding light on how 5GLAN is revolutionizing mobility within local area networks. Insight into the cost-efficient and powerful solutions that 5GLAN brings to the table, unlocking new possibilities for mobility in critical sectors such as healthcare, utilities, and manufacturing.
