As the information technology deeply changes our daily life, digital reshaping will penetrate into all industries. The communication industry has undergone several leaps and reforms during the past decades. From dial-up Internet access to FTTH and from GSM/TD-SCDMA/Wimax to LTE, information pipes have undergone radical changes, and the IT cloudification technology is reshaping CT and OT industries. The architecture of both the wireless network and wired network has been evolving into C/U separation and Fixed Mobile Convergence (FMC) to cope with all challenges brought by industrial digital transformation and industrial structure upgrade. In the predictable future, the integration at the infrastructure layer is imperative.
