Telecom operators have been building cellular networks for more than four decades. During that time, four generations have passed, many technologies have come and gone, numerous innovations and advances have occurred. Cellular smartphones have even fundamentally changed how we live, work and play. All the while, how the cellular networks are built has hardly changed. But now, the industry is on the cusp of a major transformation that will entirely change how cellular networks are orchestrated, deployed, and managed, all enabled by a new approach brought by the culmination of virtual RAN (vRAN), Open RAN, and cloudification.
