Public Field Trial of a Multi-RAT (60 GHz 5G/ LTE/WiFi) Mobile Network

Abstract

A public field trial showcasing an operational RAT mobile network was implemented in one of the largest shopping malls in Warsaw, Poland. The network supports novel 60 GHz 5G mobile access as well as legacy LTE and WiFi services All mobile access services of the network are interconnected via optical fiber to the data centers of a mobile network operator and an Internet service provider. Fronthauling for the 60 GHz 5G hotspot RAU and for LTE is realized by analog RoF via a fiber optic DAS. The 60 GHz 5G RAUs for the eMBB use case and the WiFi AP are both backhauled via optical Gigabit Ethernet. The 60 GHz RAUs for the eMBB and hotspot use case feature 2D beam-switching and 1D beam-steering, respectively. Inter-RAT switching between the different mobile services with seamless user experience is achieved using a Mobile IP system with FILS.
