# Wi-Fi 7 explained: what it is, how it compares to Wi-Fi 6E, and whether to upgrade > Wi-Fi 7 (IEEE 802.11be) adds 320 MHz channels, 4K QAM and multi-link operation. What each does, real speeds, device support and when to upgrade. - URL: https://computese.com/wi-fi-7-standard-set-to-achieve-certification-in-early-2024-bringing-advanced-connectivity/ - Author: Duong Quan Nguyen, CEO, Computese - Published: 2024-01-02 - Updated: 2026-09-25 - Topics: IT support ## In short - Wi-Fi 7 is the Wi-Fi Alliance's name for IEEE 802.11be. Wi-Fi CERTIFIED 7 launched on January 8, 2024; the IEEE approved the standard on September 26, 2024 and published it on July 22, 2025. - Its main features are 320 MHz channels in the 6 GHz band, 4K QAM, multi-link operation (MLO) across bands, and multiple resource units with puncturing to use crowded spectrum better. - Real speeds sit far below the 30 Gbit/s design goal: a two-stream laptop card peaks at 5.8 Gbps on a 320 MHz channel, and Apple's Wi-Fi 7 iPhones and Macs list 2,400 Mbps on 160 MHz. - You need a Wi-Fi 7 router, Wi-Fi 7 devices and, for the widest channels, a 6 GHz band your regulator allows: the US opened 1,200 MHz in 2020, the EU 480 MHz in 2021. - Buy Wi-Fi 7 when you replace a router or access points anyway. Wi-Fi 8 (IEEE 802.11bn) targets reliability rather than peak speed, with IEEE approval expected around May 2028. Wi-Fi 7 is the Wi-Fi Alliance's name for IEEE 802.11be, the seventh generation of Wi-Fi. It adds 320 MHz channels in the 6 GHz band, denser 4K QAM modulation and multi-link operation, which lets a device use two bands at once. Certification began on January 8, 2024, and the IEEE approved the standard that September. This page first ran on January 2, 2024, as a news item: Wi-Fi 7 certification was days away. It is now an explainer with the dates made explicit. It covers what happened after certification, what each headline feature does, how Wi-Fi 7 compares with Wi-Fi 6E, 6 and 5, why real speeds sit far below the advertised maximum, what you need to benefit, which phones and laptops support it as of September 2026, whether to upgrade a home or a small office, and what Wi-Fi 8 will change. Setting up the router is a separate job: see [how to set up a secure home network](https://computese.com/how-to-set-up-secure-home-network/) for day one, [how to set up a secure home Wi-Fi network](https://computese.com/how-to-set-up-secure-home-wi-fi-network/) for the Wi-Fi security settings, [how to secure your home network](https://computese.com/how-to-secure-your-home-network/) to harden what you already run, and [how to improve Wi-Fi signal strength](https://computese.com/how-to-improve-wi-fi-signal-strength/) for coverage. ## What Wi-Fi 7 is, and what happened after certification Two organizations stand behind the name. The IEEE develops the 802.11 wireless standards, and the Wi-Fi Alliance develops the certification programs that test whether products implement them correctly and work with each other. The IEEE amendment is 802.11be, Extremely High Throughput (EHT); the certification is Wi-Fi CERTIFIED 7. A box can say "Wi-Fi 7" without the product being certified, which is why the Alliance tells buyers to [look for the Wi-Fi CERTIFIED 7 seal](https://www.wi-fi.org/beacon/jeff-platon/buying-wi-fi-7-router-here-what-matters) or check its Product Finder. Certification came first. The Wi-Fi Alliance [launched Wi-Fi CERTIFIED 7 on January 8, 2024](https://www.wi-fi.org/news-events/newsroom/wi-fi-alliance-introduces-wi-fi-certified-7), with products from Broadcom, CommScope RUCKUS, Intel, MaxLinear, MediaTek and Qualcomm as the test bed, and cited an IDC forecast of more than 233 million Wi-Fi 7 devices entering the market in 2024, growing to 2.1 billion by 2028. The IEEE finished about eight months later: its Standards Board [approved IEEE 802.11be-2024](https://standards.ieee.org/ieee/802.11be/7516/) on September 26, 2024, and the standard was published on July 22, 2025. | Date | Milestone | | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | March 21, 2019 | The IEEE approves the 802.11be project | | January 7, 2021 | The Wi-Fi Alliance [certifies Wi-Fi 6E](https://www.wi-fi.org/news-events/newsroom/wi-fi-alliance-delivers-wi-fi-6e-certification-program), Wi-Fi 6 in the 6 GHz band | | January 8, 2024 | Wi-Fi CERTIFIED 7 launches | | September 26, 2024 | The IEEE approves 802.11be-2024 | | July 22, 2025 | The IEEE publishes 802.11be-2024 | | January 6, 2026 | Wi-Fi 7 certification is [extended to devices that use only 20 MHz channels](https://www.wi-fi.org/news-events/newsroom/wi-fi-alliance-extends-wi-fi-certified-7-20-mhz-only-devices) | The last row matters more than it looks. Sensors, wearables and other small devices are typically built for 20 MHz channels, and the 20 MHz-only certification lets them use Wi-Fi 7 features such as multi-link operation without the wide channels. Wi-Fi 7 is no longer only a speed upgrade for laptops. The Alliance's [Wi-Fi generations page](https://www.wi-fi.org/wi-fi-macphy), citing ABI Research, puts 2026 shipments at 1.4 billion Wi-Fi 7 chipsets against 2.2 billion for Wi-Fi 6. On the software side, [Windows 11 supports Wi-Fi 7 from version 24H2](https://support.microsoft.com/en-us/windows/experience/connectivity-networking/faster-and-more-secure-wi-fi-in-windows). ## The four features that matter, in plain words The certification lists several features. Four change what you notice; the others, such as 512 Compressed Block Ack and Triggered Uplink Access, trim protocol overhead and help latency-sensitive traffic. ### 320 MHz channels in the 6 GHz band A channel is the slice of radio spectrum a router and a device talk over. A wider slice carries more data per second, the way more lanes carry more cars. Wi-Fi 6 and 6E stop at 160 MHz; Wi-Fi 7 doubles that to 320 MHz, which the Wi-Fi Alliance says gives twice the throughput of Wi-Fi 6. The catch is where such a channel fits. 320 MHz channels exist only in the 6 GHz band, and only where the regulator has opened it to Wi-Fi. The [FCC opened 1,200 MHz](https://docs.fcc.gov/public/attachments/DOC-363945A1.pdf) in the US in April 2020, enough for three 320 MHz channels side by side. The [EU harmonized 480 MHz](https://eur-lex.europa.eu/eli/dec_impl/2021/1067/oj/eng), 5,945 to 6,425 MHz, in June 2021: room for one. Width also has a cost: Apple's [recommended router settings](https://support.apple.com/en-us/102766) note that wider channels are faster but more susceptible to interference, and more likely to interfere with other devices. ### 4K QAM: more bits in every symbol Quadrature amplitude modulation (QAM) is how Wi-Fi turns bits into radio symbols. Wi-Fi 6 uses up to 1024-QAM, which carries 10 bits per symbol. Wi-Fi 7 adds 4096-QAM, or 4K QAM, which carries 12, so the same channel moves [20% more data](https://www.qualcomm.com/wi-fi/wi-fi-7). The price is precision: with 4,096 possible symbols, each differs very little from its neighbours, and the receiver needs a strong, clean signal to tell them apart. 4K QAM is a bonus you get close to the router, not across the house. ### Multi-link operation: two bands at once Before Wi-Fi 7, a phone or laptop used one channel in one band at a time. Multi-link operation (MLO) lets a device and a router hold links in two or more bands at once, for more throughput, lower latency and better reliability. Qualcomm describes two ways to use those links: simultaneous, which adds them together for peak throughput, and alternating, which moves traffic to whichever band is clearer. For most people the second matters more: a video call keeps going when one band gets crowded. ![A router sends data to a laptop over two curved links at once. A cloud of interference sits on the upper link, while packets keep flowing along the lower, orange link.](https://computese.com/images/blog/wi-fi-7-standard-set-to-achieve-certification-in-early-2024-bringing-advanced-connectivity/multilink.4c41fc3259-1536.webp) *Two links let traffic step around a busy band instead of waiting for it to clear.* MLO needs support at both ends, and you can check whether you have it. In Windows 11, open the network's properties under **Settings > Network & internet > Wi-Fi**: if **Network band (channel)** lists more than one band, such as 5 GHz and 6 GHz, the connection uses MLO. ### Multiple resource units and puncturing Wi-Fi 6 introduced OFDMA, which divides a channel into resource units (RUs) so several devices can share one transmission. Wi-Fi 7 can assign several RUs to a single device, which the Wi-Fi Alliance says gives the router more flexibility when it schedules traffic. Puncturing solves a different problem. In earlier generations, interference on part of a channel, from a neighbour's network or another user of the band, stopped the router from using the rest of that channel. With Wi-Fi 7's preamble puncturing, the router leaves out the busy slice and, in Intel's words, [transmits on the unused portions](https://www.intel.com/content/www/us/en/products/docs/wireless/wi-fi-7.html) instead of blocking the entire channel. A wide channel stays usable in a crowded building. ![A router sends a wide stream across a channel drawn as eight segments. A neighbouring router occupies one orange segment, and the stream splits around it through the other seven.](https://computese.com/images/blog/wi-fi-7-standard-set-to-achieve-certification-in-early-2024-bringing-advanced-connectivity/puncture.a798571331-1536.webp) *Puncturing gives up one busy slice of the channel, not the whole channel.* ## Wi-Fi 7 vs Wi-Fi 6E, Wi-Fi 6 and Wi-Fi 5 A connection uses the best features that both the router and the device support. The generations compare like this, with the introduction years the Wi-Fi Alliance gives and peak rates for a typical two-stream device from Intel's [protocol summary](https://www.intel.com/content/www/us/en/support/articles/000005725/wireless/legacy-intel-wireless-products.html), its [BE200 specifications](https://www.intel.com/content/www/us/en/products/sku/230078/intel-wifi-7-be200/specifications.html) and Apple's [Wi-Fi specifications](https://support.apple.com/guide/deployment/wi-fi-ethernet-specifications-apple-devices-dep268652e6c/web): | | Wi-Fi 5 | Wi-Fi 6 | Wi-Fi 6E | Wi-Fi 7 | | ---------------------------- | ----------------------------------- | ------------------------- | ------------------------- | ------------------------------------------- | | IEEE standard | 802.11ac | 802.11ax | 802.11ax | 802.11be | | Introduced | 2014 | 2018 | 2021 | 2024 | | Bands | 5 GHz (most products are dual-band) | 2.4 and 5 GHz | 2.4, 5 and 6 GHz | 2.4, 5 and 6 GHz | | Widest channel | 160 MHz (802.11ac wave 2) | 160 MHz | 160 MHz | 320 MHz, in 6 GHz only | | Densest modulation | 256-QAM | 1024-QAM | 1024-QAM | 4096-QAM (4K QAM) | | Sharing a channel | Multi-user MIMO (wave 2) | OFDMA and multi-user MIMO | OFDMA and multi-user MIMO | Adds several RUs per device, and puncturing | | Several bands at once | No | No | No | Yes, multi-link operation | | Peak rate, two-stream device | 1.73 Gbps at 160 MHz | 2.4 Gbps at 160 MHz | 2.4 Gbps at 160 MHz | 5.8 Gbps at 320 MHz | Wi-Fi 7 vs Wi-Fi 6E comes down to this: both use 6 GHz, and a Wi-Fi 7 device that uses neither 320 MHz channels nor 4K QAM has the same peak rate as a Wi-Fi 6E one. Apple's Wi-Fi 7 iPhones, for example, list 2,400 Mbps on 6 GHz for both generations. What such a device gains is multi-link operation and puncturing: steadier connections when the air is busy, rather than a higher number. ## Why real-world speeds are far below the maximum Wi-Fi 7's biggest numbers describe the standard and the access point, not your phone. The IEEE's goal for 802.11be was at least one mode reaching a maximum throughput of at least 30 Gbit/s. Qualcomm's largest Wi-Fi 7 access point platforms, with up to 16 spatial streams, reach 33 Gbps of combined PHY rate, and that capacity is shared by every device on the access point. A single device sees far less, for five reasons: 1. **It has two spatial streams.** The BE200 is a 2x2 card, and Apple and Google list two streams for their Wi-Fi 7 phones. The best two-stream rate on a spec sheet is 5.8 Gbps, and only with a 320 MHz channel and 4K QAM together. 2. **Many Wi-Fi 7 devices use neither.** Apple lists 160 MHz and 2,400 Mbps for its Wi-Fi 7 iPhones and Macs, and Intel sells a Wi-Fi 7 module, the BE202, rated at 2.4 Gbps. 3. **The PHY rate is not throughput.** The spec-sheet figure is the raw rate of the radio link. Intel's own best case assumes 90% efficiency in the 6 GHz band, turning a theoretical 5.76 Gbps into an estimated 5.19 Gbps over the air, and in a real building the channel is also shared with every other device and network on it. 4. **Distance and walls cost the most.** Microsoft's [home layout guide](https://support.microsoft.com/en-us/windows/experience/connectivity-networking/wi-fi-and-your-home-layout) says 6 GHz gives the best performance when you are close to the router and has a shorter range than the other bands, and 4K QAM needs a strong signal. 5. **The wired side and the internet plan set a ceiling.** Wi-Fi cannot move data faster than the link behind it. Ubiquiti's [U7 Pro](https://techspecs.ui.com/unifi/wifi/u7-pro) access point, for example, lists 5.8 Gbps on its 6 GHz radio but has a single 2.5 GbE uplink. For anything that comes from the internet, your plan is the limit. ![A chain from an internet cloud to a modem, a router and a laptop. The thin orange line from the internet is the narrowest link: grey packets pile up in front of it, while the cable and Wi-Fi beyond carry only a few.](https://computese.com/images/blog/wi-fi-7-standard-set-to-achieve-certification-in-early-2024-bringing-advanced-connectivity/bottleneck.5582ba90f6-1536.webp) *Wi-Fi runs only as fast as the narrowest link behind it, which for internet traffic is often the plan itself.* To find your own ceiling, compare a wired speed test with Wi-Fi tests near the router and where you actually work, as described in [how to improve Wi-Fi signal strength](https://computese.com/how-to-improve-wi-fi-signal-strength/). ## What you need to benefit from Wi-Fi 7 Wi-Fi 7 features work only when every part of the connection supports them. Check these in order: 1. **A Wi-Fi 7 router or access point.** Prefer one that is Wi-Fi CERTIFIED 7: certified products are tested for interoperability, backward compatibility and WPA3 support. 2. **Wi-Fi 7 devices.** Older devices connect to a Wi-Fi 7 router with their own generation's features. Apple, for example, says its Wi-Fi 6E devices [can join Wi-Fi 7 networks](https://support.apple.com/en-us/148165), but only its Wi-Fi 7 models support all the features. 3. **A current operating system and driver.** On Windows, that means Windows 11 version 24H2 or later, with an adapter and driver that report `802.11be`. 4. **The 6 GHz band, where your country allows it.** The 320 MHz channels need it. Where regulators have not approved 6 GHz Wi-Fi, Apple devices use only the 2.4 and 5 GHz bands. 5. **WPA3.** The Wi-Fi Alliance has required WPA3 support in new certified devices since 2020, and [WPA3 is mandatory in the 6 GHz band](https://www.wi-fi.org/system/files/WPA3_Deployment_Options_Highlights_202602.pdf). Devices that know only WPA2 stay on 2.4 or 5 GHz. 6. **A wired side that keeps up.** Multi-gigabit ports on the router and switches when your internet plan or local file transfers go beyond what a 1 GbE port carries. To check a Windows PC, run this in Terminal and read the **Radio types supported** line: `802.11be` means Wi-Fi 7, `802.11ax` means Wi-Fi 6 or 6E. ```powershell netsh wlan show drivers ``` ### Where 6 GHz Wi-Fi is allowed Each country's regulator decides how much of the 6 GHz band Wi-Fi may use, and that decides how much Wi-Fi 7 you get: - **United States:** the FCC made 1,200 MHz, 5.925 to 7.125 GHz, available on April 23, 2020. Low-power indoor access points may use all of it; standard-power access points get 850 MHz, under an automated frequency coordination system that stops them operating where they could interfere with licensed services. - **European Union:** Implementing Decision (EU) 2021/1067 of June 17, 2021 harmonized 5,945 to 6,425 MHz, which member states had to make available by December 1, 2021. In November 2025 the EU's Radio Spectrum Policy Group advised the European Commission not to open the upper part, 6,425 to 7,125 MHz, to Wi-Fi, a recommendation the Wi-Fi Alliance [publicly opposed](https://www.wi-fi.org/news-events/newsroom/wi-fi-alliance-strongly-disagrees-rspg-recommendation-blocking-wi-fi-access). - **Mainland China:** Apple notes that Wi-Fi 7 is supported there but is not available in 6 GHz. For other countries, the Wi-Fi Alliance keeps a [map of 6 GHz regulations](https://www.wi-fi.org/regulations-enabling-6-ghz-wi-fi) showing which have adopted the lower part of the band and which the whole of it. > [!IMPORTANT] > Where 6 GHz is not allowed, a Wi-Fi 7 router can still run multi-link operation across 2.4 and 5 GHz, but not the 320 MHz channels behind the headline speeds. Check your country before paying for them. ## Which phones and laptops support Wi-Fi 7 (as of September 2026) From the vendors' own specification pages, as of September 2026: | Devices | With Wi-Fi 7 | Notes | | --------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------- | | Apple iPhone | iPhone 16 Pro and 16 Pro Max or later, and iPhone Air | Not the iPhone 16e or 17e; 160 MHz, two streams, 2,400 Mbps | | Apple Mac | MacBook Air with M5 or later; MacBook Pro with M5 Pro or M5 Max or later; Mac mini with M5 Pro or later; Mac Studio with M5 Max or later | 160 MHz, two streams, 2,400 Mbps | | Apple iPad | iPad Pro with M5 or later; iPad Air with M4 or later | 160 MHz, two streams, 2,400 Mbps | | Google Pixel | Pixel 10 Pro, 10 Pro XL and 10 Pro Fold; Pixel 11 Pro, 11 Pro XL and 11 Pro Fold | Pixel 10, Pixel 11 and Pixel 10a list Wi-Fi 6E | | Windows laptops | Models with Intel Wi-Fi 7 modules (BE200 and BE201 at 5.8 Gbps, BE202 at 2.4 Gbps) or Qualcomm FastConnect 7800 (5.8 Gbps), such as Microsoft's Surface Laptop for Business, 7th Edition, with Intel Core Ultra (Series 2) | Windows 11 version 24H2 or later | The Apple rows combine Apple's [list of devices that support all Wi-Fi 7 features](https://support.apple.com/en-us/148165) with its Wi-Fi specifications, which also list Wi-Fi 7 for the iPhone 16 and 16 Plus; the table follows the narrower all-features list. The Pixel models come from [Google's hardware tech specs](https://support.google.com/pixelphone/answer/7158570?hl=en), which list Wi-Fi 7 (802.11be) with 2x2 MIMO on the Pro models, and the Surface example from [Microsoft's tech specs](https://learn.microsoft.com/en-us/surface/tech-specs/surface-laptop-intel-tech-specs), which note that the 6 GHz band is not available in all regions. Two things stand out. First, "Wi-Fi 7" on a spec sheet covers a wide range: Intel's modules run from 2.4 to 5.8 Gbps, and Apple's Wi-Fi 7 devices use 160 MHz channels. Second, base models lag: Google's non-Pro Pixels and Apple's e-series iPhones still ship without Wi-Fi 7. To check a device you already own, use the `netsh` command above on Windows, or look up the model's specifications for "802.11be". ## Is Wi-Fi 7 worth it for your home? For most homes, Wi-Fi 7 is worth buying when you replace the router, not a reason to replace one that works. Upgrade now if: - **Your router no longer gets firmware updates.** Then you need a new one anyway, and a Wi-Fi 7 model will serve the next several years of devices. [How to secure your home network](https://computese.com/how-to-secure-your-home-network/) explains how to check. - **You pay for a multi-gigabit plan** and want Wi-Fi to carry more of it. The gain over Wi-Fi 6E comes from the 320 MHz channels, so you also need a device that uses them and a router with a multi-gigabit port. - **You own several Wi-Fi 7 or 6E devices** and live where 6 GHz is open. - **Your building is crowded with networks.** Multi-link operation and puncturing are built for congested air, and multi-link operation works even without 6 GHz. Wait if: - **Most of your devices are Wi-Fi 5 or 6.** They will connect at their own generation's speed until you replace them. - **Coverage is the problem.** A new standard does not push signal through more walls, and 6 GHz has the shortest range of the three bands. Better placement, a mesh system or a wired access point fixes dead zones; a faster radio in the same corner does not. - **Your plan is already well within what your current Wi-Fi delivers** near the router. If you do buy, set it up securely from the first day: [how to set up a secure home network](https://computese.com/how-to-set-up-secure-home-network/) is the checklist. ## Is Wi-Fi 7 worth it for a small office? An office is a different calculation. More devices share the air, access points stay in the ceiling for years, and the wired network and sign-in method matter as much as the radio. Work through it in this order: 1. **Count the clients.** List laptops and phones by Wi-Fi generation. If few are Wi-Fi 7 today, the gain comes as they are replaced, and multi-link operation and puncturing help sooner than 320 MHz channels in an office with neighbours on every side. 2. **Check the switches.** Wi-Fi 7 access points often want multi-gigabit, higher-power ports. The U7 Pro, for example, has a 2.5 GbE uplink and is powered by PoE+, drawing up to 21 W. A 1 GbE switch port caps such an access point at 1 Gbps, and a switch that cannot supply PoE+ needs an injector or a replacement. 3. **Check how devices sign in.** If staff connect with WPA3-Enterprise or 802.1X, note that as of September 2026 Microsoft states that [Wi-Fi 7 Enterprise is not supported in Windows 11](https://support.microsoft.com/en-us/windows/experience/connectivity-networking/faster-and-more-secure-wi-fi-in-windows). Test with your own laptops before you count on Wi-Fi 7 features for them. 4. **Keep older devices working.** Printers, scanners and older phones that know only WPA2 cannot join a 6 GHz network. Give them WPA3 transition mode or a separate network on 2.4 or 5 GHz, as the Wi-Fi Alliance's WPA3 deployment guide describes. 5. **Buy certified equipment from a product line that still gets firmware updates**, and check certification in the Wi-Fi Alliance's Product Finder. Access points are part of an office's replacement cycle, like laptops. Our [IT support service](https://computese.com/services/it-support/) keeps an asset register with advice on what to replace and when, and takes on projects such as a new office or a device refresh. ## What comes next: Wi-Fi 8 (IEEE 802.11bn) Wi-Fi 8 is built on IEEE P802.11bn, Ultra High Reliability (UHR), a project the IEEE approved on September 21, 2023. It does not chase a new peak speed. Its [stated goals](https://standards.ieee.org/ieee/802.11bn/11393/), compared with Wi-Fi 7, are 25% more throughput at a given signal quality, 25% lower latency at the 95th percentile, and 25% fewer lost frames, especially when a device moves between access points. It also aims to cut access point power use and improve device-to-device links, in the same bands between 1 and 7.25 GHz, backward compatible with earlier Wi-Fi. The Wi-Fi Alliance lists [Wi-Fi 8 among its current work areas](https://www.wi-fi.org/current-work-areas). The feature researchers point to is coordination between access points. A [2023 primer on 802.11bn](https://arxiv.org/abs/2303.10442) expects Wi-Fi 8 to introduce multi-AP coordination, so that neighbouring access points schedule their transmissions instead of competing for the channel, building on Wi-Fi 7's multi-link operation. The dates are expected, not fixed. The IEEE 802.11 working group's [official timeline](https://www.ieee802.org/11/Reports/802.11_Timelines.htm), dated September 19, 2026, shows 802.11bn in its second draft and predicts final approval by the IEEE Standards Board in May 2028. Wi-Fi 7's certification preceded its IEEE approval by about eight months, but the Alliance's work-areas page gives no certification date for Wi-Fi 8. For a purchase today, that makes Wi-Fi 8 a reason to buy certified Wi-Fi 7 equipment with a long update life, not a reason to wait. Mobile networks are moving on in parallel; our guide to [5G and 6G](https://computese.com/5g-and-6g-networking-powering-the-future/) covers that timeline. ## Key terms - **Wi-Fi 7 (IEEE 802.11be)**: The seventh generation of Wi-Fi. IEEE 802.11be, Extremely High Throughput (EHT), is the standard; Wi-Fi CERTIFIED 7 is the Wi-Fi Alliance's certification of products built to it. - **6 GHz band**: The newest Wi-Fi band, 5,925 to 7,125 MHz in the US. Each country's regulator decides how much of it Wi-Fi may use, and Wi-Fi 7's 320 MHz channels exist only there. - **Channel width**: How much spectrum one connection uses at a time: up to 160 MHz in Wi-Fi 6 and 6E, 320 MHz in Wi-Fi 7. Wider channels are faster but more exposed to interference. - **4K QAM (4096-QAM)**: Wi-Fi 7's densest modulation. It carries 12 bits per symbol against 10 for Wi-Fi 6's 1024-QAM, so 20% more data, when the signal is strong and clean. - **Multi-link operation (MLO)**: A Wi-Fi 7 feature that lets a device keep links in two or more bands at once, to add them together or to move traffic to whichever band is clearer. - **Resource unit (RU)**: A slice of a channel that OFDMA assigns to one device, so several devices can share a transmission. Wi-Fi 7 can give one device several RUs. - **Preamble puncturing**: Leaving out the busy part of a wide channel and transmitting on the rest, instead of giving up the whole channel when part of it has interference. - **PHY rate**: The raw rate of the radio link, the figure on spec sheets. Real throughput is lower, after protocol overhead, shared airtime, distance and walls. - **Spatial stream**: An independent data stream sent over its own antenna path. Phones and laptops typically use two; large access points use more, shared among all their clients. - **Wi-Fi 8 (IEEE 802.11bn)**: The next Wi-Fi generation, Ultra High Reliability. It aims at more throughput at a given signal level, lower latency and fewer lost frames, rather than a higher peak rate. ## Common questions ### Is Wi-Fi 7 worth it? It is worth buying when you replace a router or access points anyway, when you have Wi-Fi 7 or 6E devices, and when 6 GHz is allowed where you live. If most of your devices are Wi-Fi 5 or 6, or your internet plan is already well within what your current Wi-Fi delivers, a Wi-Fi 7 router changes little. It does not fix coverage: that takes better placement, mesh or wired access points. ### What is the difference between Wi-Fi 7 and Wi-Fi 6E? Both use the 6 GHz band. Wi-Fi 7 adds 320 MHz channels (Wi-Fi 6E stops at 160 MHz), 4K QAM, multi-link operation, and multiple resource units with puncturing. Apple's Wi-Fi 7 iPhones, for example, list the same 2,400 Mbps peak on 6 GHz for Wi-Fi 7 as for Wi-Fi 6E; what they gain is steadier connections on busy networks. ### Will my older devices work with a Wi-Fi 7 router? Yes. Wi-Fi 7 is backward compatible, and certified products are tested with earlier Wi-Fi generations. Older devices connect with their own generation's features, and devices that support only WPA2 cannot use the 6 GHz band, where WPA3 is mandatory. ### How fast is Wi-Fi 7 in real life? The fastest two-stream laptop cards list a PHY rate of 5.8 Gbps on a 320 MHz channel, and Intel estimates about 5.19 Gbps over the air at best. Apple's Wi-Fi 7 iPhones and Macs list 2,400 Mbps. Real downloads are lower again, limited by distance, other devices, the wired network and the internet plan. ### Does Windows 11 support Wi-Fi 7? Yes, from Windows 11 version 24H2, with a Wi-Fi 7 adapter and driver. Run netsh wlan show drivers and look for 802.11be under Radio types supported. As of September 2026, Microsoft states that Wi-Fi 7 Enterprise is not supported. ### When will Wi-Fi 8 come out? Wi-Fi 8 is based on IEEE 802.11bn, Ultra High Reliability, which was still a draft in September 2026. The IEEE's own timeline expects final approval around May 2028, so anything sold as Wi-Fi 8 before then implements a draft. ## Sources 1.
