摘要：
5G is expected to support sub-millisecond latency as well as ultra-high throughput of 20 Gbps that is a 100x improvement compared to its predecessor 4G/LTE. However, there exists a vacuum in understanding how 5G as a technology performs in the wild and whether it can fulfill its promises. To fill these voids, we examine the commercial 5G landscape across several key dimensions -- network performance, radio power characteristics, and quality-of-experience implications for mobile applications -- to provide key insights for interested stakeholders, and propose intelligent mechanisms for application developers to better leverage 5G technology. To this end, using tools we developed in-house, we conducted a detailed measurement study to provide a first impression of the network performance characteristics of 5G services (including that of the much-anticipated mmWave). Subsequently, we expanded its scope and conducted the first comprehensive measurement study to investigate the power consumption of 5G radio on commodity smartphones. Overall, our findings reveal key characteristics of commercial 5G services in terms of throughput, latency, performance bottlenecks, coverage, radio state transitions, and radio power consumption under diverse scenarios, application usage (file download, web browsing, video streaming) with detailed comparisons to 4G/LTE networks. Furthermore, we also quantitatively reveal critical trade-offs (e.g., ultra-high vs. stable network performance, performance vs. energy) that get amplified with 5G. Leveraging the above insights, we further proposed a data-driven deep-learning-based framework for mmWave 5G through
