The industry consensus is that 5G should be known not only for its cutting-edge radio access technologies, but also for the way it integrates cross-domain networks so operators can provide networks on a need-for-service basis. 5G will enable new verticals, new services and new business models that aren’t possible or practical with 4G and other legacy mobile technologies. Examples includes wearables for advanced telemedicine applications, virtual/augmented reality, UHD video a
