Mark Reudink, VP of technology strategy at Crown Castle, spoke about the potential of 5G at last week's 6G Symposium. "As we talk about where we are in the state of the rollout of 5G, most 5G networks today, especially the commercial networks are still tied into a 4G core," he said. "We haven't really moved into that true 5G infrastructure with the low-latency capabilities at this stage."
