Wi-Fi and 5G can both deliver high throughput, but their performance characteristics differ. Wi-Fi depends heavily on your access point and local interference; cellular depends on radio conditions, network load and operator routing.
When Wi-Fi wins
A well-positioned modern access point with a fast fixed connection often provides stable indoor performance.
When cellular wins
Strong cellular coverage can outperform congested or poorly placed Wi-Fi, especially when the fixed connection is slow.
Best comparison
Run the same diagnostic on each connection from the same device and location, then compare latency, jitter, loss and throughput together.
