5G is the fifth-generation cellular network technology designed to deliver faster data speeds, lower latency, and increased reliability compared to previous generations. In the context of Unreal Engine and pixel streaming platforms like Arcane Mirage, 5G enables seamless transmission of high-fidelity 3D content over mobile networks. This technology is instrumental in enhancing remote collaboration, virtual events, and real-time interactive experiences where responsiveness and bandwidth are critical. By leveraging 5G, Unreal Engine applications can deliver immersive content to mobile devices and VR headsets with minimal delay and maximum visual quality.
