What role will 6G play in immersive media?

6G networks will play a central role in supporting immersive media and Extended Reality (XR) by enabling extreme network capabilities, such as terabits-per-second (Tbps) data rates and microsecond-level latencies ^[1][2]. These capabilities are expected to support cloud-rendered XR at scale by decoupling VR and AR headsets from tethered consoles or workstations, allowing heavy computing tasks to shift to the network edge while delivering real-time, multi-sensory experiences ^[3]. To achieve these high throughputs, 6G research focuses on leveraging the terahertz (THz) spectrum (0.1–10 THz) alongside advanced photonics-assisted signal generation and multi-dimensional multiplexing ^[4]. Regarding research timelines, 6G wireless networks are currently under investigation, with large-scale deployments anticipated after 2030 ^[5]. However, realizing this infrastructure involves notable hurdles, including overcoming electronic bandwidth bottlenecks and severe phase noise in conventional THz systems, managing gain saturation in single carriers, and addressing long-distance link and space application challenges ^[6].
