Wi-Fi 7 MLO vs Single-Link Throughput
Wi‑Fi 7 can use Multi‑Link Operation (MLO) to send data over multiple links at once, while many setups still rely on single‑link transmissions. This article explains how MLO affects real throughput, why “link speed” numbers mislead, and which conditions favor multi‑link use. Readers will learn how to compare MLO and single‑link performance, what to measure on their own router and devices, and which bottlenecks still cap throughput.
