Understanding 5G Network Latency and the Role of MEC

While 5G’s radio link can reach about 1 ms, true end‑to‑end latency remains dominated by core and internet delays, so 4G, 5G‑NSA and 5G‑SA differ only modestly; however, combining 5G Standalone with Multi‑access Edge Computing can cut total latency below 10 ms, enabling ultra‑reliable low‑latency applications.
