When 5G first arrived, it came with big promises: ultra-high bandwidth, ultra-low latency, and a new generation of mobile experiences - from AR/VR to connected cars to early visions of the metaverse. Many of these applications were designed for the road, where consistency matters just as much as speed in maintaining high QoE. Yet the very design choices that give 5G its power - especially its use of higher-frequency spectrum - also make it fragile. Signals attenuate faster in higher frequency bands and coverage shrinks. And once you start moving, performance can vary wildly from one minute to the next.
Ghoshal et al. (Mon,) studied this question.
