Wi-Fi over time speed doesn't grow on its own

Every Wi-Fi number since 1997 promises 'faster' — but each jump turned exactly one dial: spectrum, channel width, QAM density, or multi-link. Trace the curve from 2 Mbps to 46 Gbps and find the one generation that didn't move the number at all.

What you'll learn

  • How to read nine Wi-Fi generations (802.11 through Wi-Fi 7) as one log-scale curve instead of nine separate marketing numbers.
  • Why Wi-Fi 6E's peak PHY rate is identical to Wi-Fi 6's (9.6 Gbps) — the flat step where the dial that moved was spectrum, not speed.
  • Why reaching Wi-Fi 7's 46 Gbps required turning three dials at once — 320 MHz, 4096-QAM and Multi-Link Operation — not one.
  • How to decompose any peak rate into streams × channel width × QAM order × efficiency, so the number on the box stops being a black box.

Nine numbers, one curve

Every Wi-Fi generation since 1997 has shipped with a bigger peak-rate number: 2 Mbps, then 11, then 54, then 600 million, then billions. Plotted on a linear axis the early jumps vanish into a flat line at the bottom. Plotted on a log scale, the whole 27-year climb becomes one legible curve — and the story stops being 'Wi-Fi got faster' and starts being 'here is exactly which lever moved, and when.'

These are peak theoretical PHY rates — the maximum a lab can coax out of the top-shelf configuration, not what your phone gets in the kitchen. That's deliberate: the point of this timeline isn't your speedometer, it's the shape of each jump.

The step that didn't rise

Between 2019 and 2020 the curve does something every other jump doesn't: it goes flat. Wi-Fi 6E's peak PHY rate is 9.6 Gbps — the exact same ceiling as Wi-Fi 6, released the year before. Nothing about the radio's math changed. What changed was the real estate: 6E opened 1,200 MHz of clean 6 GHz spectrum with none of the legacy congestion that crowds 2.4 and 5 GHz. It was arguably the biggest quality-of-life jump in Wi-Fi's history, and it shows up on this chart as a flat line — proof the box number and the real improvement aren't the same axis.

Wi-Fi 7 then had to turn three dials simultaneously to reach 46 Gbps: a channel four times wider (320 MHz), a constellation twice as dense (4096-QAM), and Multi-Link Operation binding multiple bands into one logical connection. Try to match that jump one dial at a time on the bench below, and you'll find it can't be done — which is exactly the point.
