Why name only 802.11?

Wi-Fi
1

For ages I had this doubt,

Why is the 802.11 standard called 802.11?
I mean, why not 804.14?
Why is it called only 802.11?

For context,
Think of 802 like a big folder name.
Inside that folder,
there are many small sub-folders.

802 = Main folder for all computer network standards
11 = The sub-folder inside 802 that deals with Wi-Fi

So the Wi-Fi standard sits
in the 802 folder, in the 11th sub-folder.
Therefore, it’s called 802.11.

To make it simple:

802 → Group that makes networking rules
11 → The rule number for Wi-Fi
Put together → 802.11 = Wi-Fi rules

But again the same question, why only 802?
Why not 804 or something else?
Curious? Here we go!

Because the committee was formed in February 1980.

They took:

80 → from the year 1980
2 → from the month February
Combine them → 802

So they named the networking standards group IEEE 802.

To make it even more simpler:
The group that makes networking rules started in February 1980.

So they used 80 (year) + 2 (month) → 802.
That’s why the main folder is named 802.

And then Wi-Fi came under that group as project number 11 → 802.11

That’s it!

:antenna_bars: Why the name “802.11”?

The name 802.11 comes from how the IEEE (Institute of Electrical and Electronics Engineers) organizes its networking standards.

:white_check_mark: What does “802” mean?

“802” is the IEEE working group responsible for local area networks (LANs).

It was created in 1980, in the 2nd month (February).
That’s why the number is:

80 (year) + 2 (month) = 802

Within this group, there are several subgroups:

  • 802.1 → Bridging/Switching
  • 802.3 → Ethernet
  • 802.15 → Bluetooth / PAN
  • 802.16 → WiMAX
  • 802.11 → Wireless LAN (Wi-Fi)

In other words: the number is not random — it identifies the committee responsible for LAN technologies.

:magnifying_glass_tilted_right: And what about “.11”?

Inside the 802 group, each project receives a specific number.

The number 11 was assigned to the wireless LAN (WLAN) standard.

That’s why everything related to Wi-Fi is formally named IEEE 802.11.

:puzzle_piece: Why not another number, like 802.14 or 804.xx?

Because Wi-Fi was created inside the 802 working group, which already existed since 1980.

So, the number is not chosen arbitrarily — it depends on the technical committee where the project originated.

If Wi-Fi had been developed in a different committee, it would have received a completely different number.

But since all LAN technologies (wired and wireless) belong to Group 802, the standard naturally became:

  • 802 → LAN working group
  • .11 → specific wireless LAN project

Simple as that.

:satellite_antenna: Where does the name “Wi-Fi” come from?

Despite popular belief, Wi-Fi does NOT mean “Wireless Fidelity.”
That phrase was used only briefly as a marketing slogan.

The name “Wi-Fi” was created by the branding agency Interbrand to be:

  • short
  • easy to remember
  • reminiscent of “Hi-Fi” (high fidelity audio)

The brand is managed by the Wi-Fi Alliance, which certifies Wi-Fi devices.

Meanwhile:

  • Wi-Fi → commercial name
  • 802.11 → technical name of the standard

:scroll: Wi-Fi Standards Timeline (IEEE 802.11)

:blue_circle: 1997 — 802.11 (original)

  • First Wi-Fi standard ever.
  • Maximum speed: 2 Mbps.
  • Very limited, now fully obsolete.

:green_circle: 1999 — 802.11b and 802.11a

802.11b

  • The first version to make Wi-Fi truly popular.
  • 11 Mbps – 2.4 GHz
  • Affordable, good range.

802.11a

  • 54 Mbps – 5 GHz
  • Faster but with shorter range.
  • More expensive at the time, used mainly in enterprise.

:yellow_circle: 2003 — 802.11g

  • Combined the best of “b” and “a”:

    • Operated on 2.4 GHz
    • Speeds up to 54 Mbps

  • Dominated the early 2000s.

:orange_circle: 2009 — 802.11n (Wi-Fi 4)

  • Major technical leap:

    • MIMO (multiple antennas)
    • 2.4 GHz + 5 GHz
    • Channel bonding (40 MHz)

  • Theoretical speed: 600 Mbps.

  • First “modern” Wi-Fi generation.

:red_circle: 2013 — 802.11ac (Wi-Fi 5)

  • 5 GHz only.

  • Introduced:

    • MU-MIMO
    • 80/160 MHz channels
    • Higher-order modulation

  • Typical speeds: 1–3 Gbps.

  • Dominated most of the 2010s.

:purple_circle: 2019 — 802.11ax (Wi-Fi 6 / Wi-Fi 6E)

Wi-Fi 6: 2.4 + 5 GHz
Wi-Fi 6E: 2.4 + 5 + 6 GHz

Key features:

  • OFDMA
  • Uplink MU-MIMO
  • Better efficiency in dense environments
  • Access to the brand-new 6 GHz band

Max theoretical speed: 9.6 Gbps.

:purple_square: 2024/2025 — 802.11be (Wi-Fi 7)

The most advanced Wi-Fi ever created.

Main improvements:

  • 320 MHz channels
  • 16×16 MIMO
  • 4096-QAM
  • Multi-Link Operation (MLO) → uses multiple bands at once
  • Extremely low latency

Speeds: 30–40 Gbps.

:pushpin: One-sentence summary

Wi-Fi is the commercial name; the actual standard is always IEEE 802.11 + a revision (a, b, g, n, ac, ax, be).
