Event Description

Abstract: 5G rollout started in 2019 and the wide-scale deployment has been rapid and aggressively marketed by all mobile network operators. 5G promises unprecedented high bandwidth and ultra-low latency, particularly in the millimeter wave (mmWave) frequency bands, and holds the promise to finally support the next-generation of latency-critical applications such as augmented and virtual reality (AR/VR), panoramic video streaming, cloud gaming, and connected autonomous vehicles (CAVs), often dubbed as 5G “killer apps”. Most recent measurement studies of 5G performance have focused on measuring performance primarily in the downlink direction under static conditions while the uplink performance and the performance under driving remain largely unknown. In this talk, I will present our research efforts towards a detailed understanding of the performance of today’s 5G networks and their potential to support 5G “killer apps”. The talk will focus on the first in-depth measurement study of the mobile networks of all three major US carriers while driving across the continental US (5700km+, from Los Angeles to Boston) and our findings in terms of coverage, performance, and impact on applications. I will also discuss our recent and ongoing work on exploring the potential of 5G mmWave to support single-user and multi-user AR. I will finish by describing our recent efforts to deploy an open, programmable, multi-vendor 5G O-RAN testbed at Northeastern University.
