Seamless Switching Between Public and Non-Public 5G Network Using Smart Resource Flow Wireless Platform

In recent years, automated transportation systems have been used in factories to improve manufacturing efficiency. Trackless automated transportation systems require stable wireless communication for control and monitoring. In this system, equipment must move throughout a large factory area. In cases where outside building area is covered by a public 5G network and inside building area is covered by a non-public 5G network, a system is required to continue wireless communication seamlessly between the non-public 5G network and the public 5G network. We have developed the Smart Resource Flow (SRF) wireless platform to bundle and manage multiple wireless networks. We evaluated the impact of the SRF wireless platform on communication interruption when switching between public and non-public networks. From this evaluation, we confirmed that the communication interruption time was reduced from 9.75 s to 0.14 s by applying the SRF wireless platform.
