Mobile Edge Computing and Multi-access Edge Computing (MEC) are the same. The concept of edge computing brings computational functionality closer to the user of the data, with the goal of providing more scalable performance, reducing network load and hastening data transmission.
Edge computing distributes compute resources across networks, rather than centralized in data centers. By physically moving those resources closer to the user, MEC reduces congestion on host networks, decreases latency and offers carriers and enterprises new 5G business opportunities. MEC helps operators provide low-latency and high-bandwidth 5G applications.
