Abstract: As the deployment of 5G networks continues to expand, mobile devices such as smartphones, IoT devices, and vehicles are poised to benefit from wider spectrum and faster speed. However, such advantages come with a cost: with 5G's shorter communication range and dense deployments, a device often needs to switch its association among base stations (a process known as handover), especially when the device is in motion. In this talk, I will begin by introducing our findings regarding the adverse effects of mobility on 5G applications and the underlying root causes. I will subsequently present two solutions that aim to address this issue: a cross-layer design that mitigates the handover impact on higher layers, and an intelligent solution designed to select handover targets with low overhead. To conclude the talk, I will provide insights into our ongoing projects aimed at unleashing the full potential of 5G.
