Wi-Fi 6 vs Wi-Fi 6E vs Wi-Fi 7

Published . 8 min read

Wi-Fi 6E is a spectrum permission, not a new standard. The silicon is Wi-Fi 6 (IEEE 802.11ax) and the only change is regulatory clearance to transmit in 6 GHz, with no new PHY or MAC features attached. Wi-Fi 7 (IEEE 802.11be-2024) is the real generational step: 320 MHz channels, Multi-Link Operation and 4096-QAM. Whether any of it reaches you depends on your country's spectrum rules, then your client devices, then your internet plan.

The three side by side

IEEE SA approved 802.11be-2024 on 26 September 2024 and published it on 22 July 2025, so certified Wi-Fi 7 gear shipped roughly 18 months before the standard existed. Wi-Fi 6 moved too: Release 2, announced 5 January 2022, added uplink multi-user MIMO, broadcast Target Wake Time, extended sleep time and dynamic multi-user SMPS. A 2019 Wi-Fi 6 router and a 2023 one are not the same product.

The 46 Gbps number is wrong

Older comparisons put Wi-Fi 7's ceiling at 46 Gbps. That figure multiplies about 2.88 Gbps per stream by 16 spatial streams, and 16 streams were discussed early in 802.11be and dropped; by draft 7.0 the cap was 8, the same as Wi-Fi 6. Cisco Meraki says the same: streams in Wi-Fi 7 are "limited to 8, like the previous generation." Eight streams on a 320 MHz channel at MCS 13 works out near 23 Gbps, against the 9.6 Gbps usually quoted for Wi-Fi 6. IEEE's scope asks only for "at least 30 Gbit/s" between 1 and 7.250 GHz, and that takes aggregated links, not one faster radio.

None of those numbers describe your phone, because consumer clients are 2x2 MIMO. TP-Link rates the Archer BE550's 6 GHz radio at 5760 Mbps, 2x2 on 320 MHz with 4096-QAM, and its 5 GHz radio at 2880 Mbps, 2x2 on 160 MHz. Those PHY rates, before overhead, are the honest upper bounds.

6 GHz availability is the whole regional story

Most countries that opened 6 GHz opened only the bottom: 5925 or 5945 to 6425 MHz, roughly 500 MHz. The full 1200 MHz, 5925 to 7125 MHz, is a minority position: the United States, Canada, South Korea, Brazil, Saudi Arabia and a few others. The Wi-Fi Alliance's tracker holds the live count; published totals age fast. The EU's basis is Implementing Decision (EU) 2021/1067, 5945 to 6425 MHz. China reserved 6 GHz for cellular IMT in 2023, and Apple states the result: "Wi-Fi 6E isn't available in mainland China. Wi-Fi 7 is supported in mainland China, but isn't available in 6 GHz."

Europe shut the door on the upper band in late 2025. The RSPG opinion of November 2025 recommended the Commission not open 6425 to 7125 MHz to Wi-Fi, reserving 540 MHz for mobile and 6G and holding the last 160 MHz until WRC-27. The Wi-Fi Alliance objected on 12 November 2025. If an article predicts upper 6 GHz Wi-Fi in the EU, check its date.

The UK broke ranks on 20 July 2026, the first in Europe. Ofcom will share the upper band at a 6585 MHz divide: Wi-Fi priority on 6425 to 6585 MHz, mobile priority above it. Low power indoor and very low power use will be licence-exempt as in the lower band; outdoor, higher power and mobile-priority Wi-Fi needs AFC control. Mobile deployment is not expected before 2030, so the extra 160 MHz is decided rather than in service.

How much of the 6 GHz band each region released to Wi-Fi Three horizontal bars on one frequency scale running from 5925 to 7125 MHz. The United States and Canada released the full 1200 MHz, enough for three 320 MHz channels in low power indoor mode. The European Union released 5945 to 6425 MHz, 480 usable MHz, which fits exactly one 320 MHz channel or three at 160 MHz, and the RSPG recommended not opening 6425 to 7125 MHz to Wi-Fi. The United Kingdom decided on 20 July 2026 to add 6425 to 6585 MHz with Wi-Fi priority, an extra 160 MHz, and to share the spectrum above 6585 MHz with mobile taking priority. US and Canada 5925 to 7125 MHz 1200 MHz three 320 MHz channels European Union 5945 to 6425 MHz 480 MHz not open to Wi-Fi one 320 MHz channel United Kingdom from 20 July 2026 160 MHz mobile priority Wi-Fi priority to 6585 MHz 5925 6425 6585 7125 Frequency in MHz. Channel counts are for 320 MHz; Europe fits three at 160 MHz instead. The US and Canada count is low power indoor mode. UK mobile is not expected before 2030. The full 1200 MHz is a minority position: the US, Canada, South Korea, Brazil, Saudi Arabia.
Drawn to one 1200 MHz scale. Every region agrees on the lower band; the upper band is where they part company, and it is the part that decides how wide a channel you can select.

The FCC went the other way, adopting a fourth 6 GHz power class on 29 January 2026: geofenced variable power, 24 dBm EIRP for access points in U-NII-5 and U-NII-7, usable outdoors.

320 MHz channels are effectively a North American feature

Channel count follows from spectrum. With 1200 MHz the US and Canada fit three 320 MHz channels in low power indoor mode, per Meraki's guide; under standard power with AFC it drops to one in the US, two in Canada. Europe's 480 usable MHz fits exactly one 320 MHz channel, or three 160 MHz ones. In an apartment block every neighbour who selects 320 MHz lands on that same channel, so the wide setting costs more in contention than it returns in width. TP-Link prints the caveat itself: 320 MHz "may be unavailable in some regions/countries due to regulatory restrictions".

Apple's deployment guide caps its N1 devices at 2x2 and 160 MHz on 6 GHz, 160 MHz on 5 GHz, 20 MHz on 2.4 GHz. FCC filings confirm every iPhone 17 model is held to 160 MHz, and the iPhone 16 was capped the same way on Broadcom silicon. If your household runs iPhones and recent Macs, 320 MHz marketing is irrelevant.

4096-QAM is conditional too. Meraki puts the requirement at an SNR close to 42 dB against 31 dB for 1024-QAM under 802.11ax, and says clients must sit within a few feet of the access point. The advertised 20 percent gain over 1024-QAM exists in the same room as the router and nowhere else.

What MLO actually does on a phone

802.11be defines five multi-link modes. MLSR is mandatory for APs and clients, STR is mandatory for APs but optional for clients, and eMLSR, NSTR and eMLMR are optional throughout. STR-MLMR runs two real radios at once and genuinely adds throughput. eMLSR uses one radio that listens on two links, then switches its chains to whichever wins: better latency and reliability, no extra bandwidth.

STR-MLMR compared with eMLSR on an SSID running 5 GHz and 6 GHz Two side by side schematics of a client associated to one access point over both a 6 GHz and a 5 GHz link. On the left, STR-MLMR: the client has two real radios and both links carry data at once, so it genuinely adds throughput; STR is mandatory for access points but optional for clients. On the right, eMLSR: the client has one radio that listens on both links and switches to whichever wins, so only one link carries data at a time and the gain is latency and reliability rather than bandwidth; eMLSR is optional throughout. Two multi-link modes on a 5 plus 6 GHz SSID STR-MLMR Two real radios at once Access point Client two radios 6 GHz carries data 5 GHz carries data Both links carry data at once. Genuinely adds throughput. Mandatory for APs, optional for clients. eMLSR One radio, two links, switched Access point Client one radio 6 GHz carries data 5 GHz listening One link carries data at a time. Better latency and reliability. No extra bandwidth. Optional throughout. A solid link carries data. A dashed link is listened to but idle. 802.11be defines five multi-link modes. Arista saw no client use NSTR-MLMR or eMLMR.
Both modes are sold as Multi-Link Operation, but only the two-radio one adds bandwidth, and it is the mode clients are least likely to implement.

Arista's lab results are blunt. Most popular clients do not perform STR-MLMR when the SSID runs on 5 GHz and 6 GHz, though they will across 2.4 plus 5 GHz or 2.4 plus 6 GHz, preferring the latter. The aggregate, where it forms, pairs one fast link with one slow one.

Samsung Galaxy S24single link, no MLO
OnePlus 11STR-MLMR, data flows only on 6 GHz
Intel BE200eMLSR
Qualcomm FastConnect 7800STR-MLMR

The FastConnect 7800 manages the hard case: a High Band Simultaneous design with filtering that stops its own radios interfering. Arista observed no client using NSTR-MLMR or eMLMR. A packet-level analysis of the Galaxy S24 Ultra found it associated over 2.4 plus 6 GHz and over 5 plus 6 GHz, then ran all traffic on 6 GHz anyway, peaking at 5.8 Gbps PHY on MCS 13 at 320 MHz.

Which devices support what

Apple lists Wi-Fi 7 with MLO on the iPhone 16 and 17 families, iPhone Air, the M4 iPad Air, the M5 iPad Pro, and the M5 MacBook Pro and MacBook Air. Wi-Fi 6E started with the iPhone 15 Pro and Pro Max only; the non-Pro iPhone 15 stayed on Wi-Fi 6.

Two traps on the PC side. Intel's BE200 is widely reported not to work in AMD systems, because its CNVio2 interface expects an Intel Platform Controller Hub: the card is not detected on AM4 or AM5 boards, and driver releases have not fixed it. Separately, Wi-Fi 7 enterprise connectivity on Windows, WPA3-Enterprise included, needs Windows 11 24H2 with the September 2025 preview non-security update or later plus a certified OEM driver. That gate is enterprise-only.

WPA3 or Enhanced Open is mandatory on 6 GHz, so no WPA2-Personal or WPA2-Enterprise SSID can run on that band. Older laptops, printers and smart-home gear will fail to associate or drop repeatedly. Give the legacy kit its own WPA2 SSID; WPA3 stays optional on 2.4 and 5 GHz.

Where the upgrade buys you nothing

Your internet plan is almost certainly the ceiling. Speedtest Global Index medians for fixed broadband download in December 2025 put the United States near 303 Mbps, the United Kingdom near 163 Mbps and Germany near 102 Mbps. A 2x2 Wi-Fi 6 client on a 160 MHz channel carries roughly 2.4 Gbps of PHY headroom, so a German median connection uses about four percent of one link. The wired ports cap you too: the BE550 advertises 9214 Mbps as a BE9300 tri-band router but offers one 2.5 Gbps WAN and four 2.5 Gbps LAN ports, no 10 GbE.

"Wi-Fi 7" on the box does not mean 6 GHz. The Archer BE230 (BE3600) is dual-band, 2.4 and 5 GHz only, rated 2882 Mbps and 688 Mbps, both 802.11be, with MLO, 4K-QAM and multi-RU on TP-Link's feature list. Since 7 January 2026 the Wi-Fi Alliance also certifies 20 MHz-only Wi-Fi 7 clients, so the badge on a smart plug says even less. In a European home it differs from a decent Wi-Fi 6 router mainly by 4096-QAM you will rarely reach and MLO across 2.4 plus 5 GHz.

What to actually do

Buy Wi-Fi 7 when you are replacing a router anyway, and pay for tri-band only if you want 6 GHz for cleanliness rather than width. Mid-2026 listings put the BE230 near $120 and the BE550 near $250, with street prices under both, so the premium over Wi-Fi 6 is small. Do not replace a working Wi-Fi 6 or 6E setup for the standard alone, least of all in the EU with its single shared 320 MHz channel and no upper band on the roadmap.

Waiting for Wi-Fi 8 is not the answer either. IEEE 802.11bn, branded Ultra High Reliability, was still in draft through mid-2026, aimed at reliability and cell-edge consistency rather than a higher peak rate. Ratification estimates cluster on 2028 and certification on 2027, both projections.

One last correction. Free-space path loss at 6 GHz is only about 1 to 2 dB worse than 5 GHz over the first metre, while one interior wall costs 5 to 15 dB. The band is not what limits your range. The power rule is. Under the FCC's 5 dBm/MHz low power indoor limit, a 160 MHz AP is capped near 27 dBm EIRP, and only a 320 MHz channel reaches the 30 dBm ceiling. A 5 GHz access point may use far more power per megahertz.
