WiFi 7 (IEEE 802.11be) is the wireless networking standard that succeeds WiFi 6 (IEEE 802.11ax). It doubles the widest channel from 160 MHz to 320 MHz, raises modulation from 1024-QAM to 4096-QAM, and adds Multi-Link Operation (MLO), which lets a device use two or more bands at the same time. On paper, the peak rate rises from 9.6 Gbps to about 46 Gbps.
In a real home, the difference is smaller. A typical WiFi 7 phone or laptop connected to a WiFi 7 router can reach roughly twice the throughput of a WiFi 6 connection, with lower and more stable latency, but only when both ends support the new features and the 6 GHz band is in use. If your internet plan is under 1 Gbps and your devices are WiFi 6, upgrading the router alone will not make your connection noticeably faster.
What is WiFi 7?
WiFi 7 is the consumer name for IEEE 802.11be, also called Extremely High Throughput (EHT). The IEEE approved the amendment in September 2024 as IEEE Std 802.11be-2024. The Wi-Fi Alliance, the industry group that tests and certifies devices, launched its Wi-Fi CERTIFIED 7 program in January 2024, before the standard was formally finished, so certified routers and devices were on sale well before the final text was published.
WiFi 7 works in all three WiFi bands: 2.4 GHz, 5 GHz, and 6 GHz. Most of its speed gains, however, depend on the 6 GHz band, because that is the only band with enough free spectrum for 320 MHz channels. For the full family tree of WiFi versions, see our overview of 802.11 standards.
WiFi 7 vs WiFi 6 vs WiFi 6E at a glance
WiFi 6E is not a separate standard. It is WiFi 6 (802.11ax) extended into the 6 GHz band, certified from January 2021. So the comparison is really three steps: WiFi 6 on 2.4 and 5 GHz, WiFi 6E adding 6 GHz, and WiFi 7 adding wider channels, denser modulation, and multi-link.

The key differences explained
320 MHz channels
Channel width works like the number of lanes on a road. WiFi 6 tops out at 160 MHz. WiFi 7 allows 320 MHz, which doubles the data a single connection can carry. In the United States, the 6 GHz band offers 1,200 MHz of spectrum (5.925 to 7.125 GHz), enough for three non-overlapping 320 MHz channels. On 5 GHz, WiFi 7 is still limited to 160 MHz, because there is not enough contiguous spectrum there. If you want to understand how channel width trades speed for range and interference on 5 GHz, our guide to the best 5 GHz WiFi channel covers it in detail.
Not every WiFi 7 device uses 320 MHz. Many phones, including Apple’s iPhone 16 models, support WiFi 7 on 6 GHz but stop at 160 MHz channels. That is a hardware limit, not a setting.
4096-QAM
Quadrature amplitude modulation (QAM) packs bits into each radio symbol. WiFi 6 uses 1024-QAM, which carries 10 bits per symbol. WiFi 7 uses 4096-QAM, which carries 12 bits, a 20% increase. The catch is signal quality: 4096-QAM only works when the device is close to the router with a clean signal. At the other end of the house, a WiFi 7 link drops to lower modulation, just like WiFi 6.
Multi-Link Operation (MLO)
MLO is the feature that most clearly separates WiFi 7 from earlier generations, and it is mandatory for WiFi 7 certification. Before WiFi 7, a device connected on one band at a time. With MLO, a device can hold links on two or more bands, for example 5 GHz and 6 GHz, and either send data over both at once or switch to the cleaner link instantly.
The practical benefit is less about peak speed and more about consistency. If one band gets busy or a microwave oven disturbs 2.4 GHz, traffic moves to the other link without a reconnect. That helps video conferencing, online gaming, and VR, where short delays matter more than raw throughput. Both the router and the device must support MLO, and the operating system has to support it too. On Windows, WiFi 7 and MLO require Windows 11 version 24H2 or later.
Puncturing and Multi-RU
In WiFi 6, if part of a wide channel is busy, the router usually falls back to a narrower channel. WiFi 7 can “puncture” the busy slice and keep using the rest of the wide channel. Multi-RU lets the router assign more than one resource unit to a single device in the same transmission. Both features make better use of crowded spectrum, which matters in apartments and other dense environments where many networks overlap. WiFi 6 already introduced OFDMA and multi-user MIMO to serve multiple devices at once, and WiFi 7 builds on both, which helps smart homes with dozens of connected IoT devices.
The 6 GHz band
The 6 GHz band arrived with WiFi 6E and remains the main reason WiFi 6E and WiFi 7 feel faster than older gear. It is new, uncrowded, and only usable by recent devices, so there is no legacy traffic slowing it down. The trade-off is range: 6 GHz signals are absorbed more by walls and floors than 5 GHz, and much more than 2.4 GHz. All 6 GHz connections also require WPA3 security.
Theoretical vs real speeds
The 46 Gbps headline assumes the widest channel, the highest modulation, and more antenna streams than any phone or laptop has. It is the combined capacity of a lab setup, not the speed of one device.
Most phones and laptops use two antenna streams (2×2). For those devices, realistic best-case link rates are:
- WiFi 6 at 160 MHz on 5 GHz: about 2.4 Gbps link rate
- WiFi 7 at 160 MHz on 6 GHz: about 2.9 Gbps link rate
- WiFi 7 at 320 MHz on 6 GHz: about 5.8 Gbps link rate
Link rate is not the same as download speed. Actual throughput is usually around half to two-thirds of the link rate, and it falls with distance, walls, and competing devices. Your internet plan is the other ceiling. If your connection is 500 Mbps, both WiFi 6 and WiFi 7 can deliver that in the same room as the router. WiFi 7’s extra headroom shows up with multi-gigabit internet plans, large local file transfers to a NAS, or many active devices at once.
Range does not improve with WiFi 7. The same radio physics apply. If your problem is weak coverage at the far end of the house, a single faster router will not fix it. More access points or a mesh WiFi system will.
Does WiFi 7 go through walls better?
No. WiFi 7 uses the same 2.4 GHz, 5 GHz, and 6 GHz frequencies as WiFi 6 and WiFi 6E, and walls absorb those signals in the same way. Beamforming, which both generations use, focuses the signal toward a device but does not change the physics. MLO can make connections at the edge of coverage more stable, because a device can fall back to the 5 GHz or 2.4 GHz link when the 6 GHz link weakens, but the usable range stays about the same.
Disadvantages of WiFi 7
- Price: WiFi 7 routers and mesh systems usually cost more than WiFi 6 models with similar coverage.
- Few devices use every feature: many clients lack 320 MHz support or MLO, so the router’s full capacity goes unused.
- Short range at full speed: the biggest gains need the 6 GHz band, which covers less area than 5 GHz.
- Higher power consumption: more radios and wider channels draw more power in the router, which also produces more heat.
- Wired bottlenecks: to benefit from multi-gigabit WiFi, the router needs a 2.5 Gbps or faster Ethernet port and a matching internet plan or local network.
Security in WiFi 7
WiFi 7 does not introduce a new encryption scheme, but it raises the minimum. WPA3 is required for any 6 GHz connection, and routers generally only enable MLO with WPA3, so a WiFi 7 network that uses its main features also uses current security. Older devices on 2.4 GHz and 5 GHz may still connect with WPA2 if you enable a mixed mode.
Device support and backward compatibility
WiFi 7 routers are backward compatible. WiFi 6, WiFi 5, and older devices connect to them normally and run at their own generation’s speed. Likewise, a WiFi 7 phone works fine on a WiFi 6 router, it just cannot use 320 MHz, 4096-QAM, or MLO.
To get WiFi 7 features, you need all of the following:
- A WiFi 7 router or access point
- A WiFi 7 client device (phone, laptop, or WiFi adapter)
- An operating system and drivers that support it, such as Windows 11 24H2 or later on PCs
- 6 GHz support on both sides for 320 MHz channels
Flagship phones and many newer laptops have supported WiFi 7 since 2024. Budget devices, smart TVs, streaming boxes, and smart home gadgets often still use WiFi 5 or WiFi 6, and many smart home devices stay on 2.4 GHz only.
WiFi 6 vs 7 for mesh systems
In mesh systems, the link between nodes, called backhaul, often decides real-world speed. WiFi 7 mesh systems can use a 6 GHz 320 MHz link or MLO between nodes, which gives the backhaul more capacity than a WiFi 6 system. If you use wired Ethernet backhaul, this advantage is smaller.
What comes after WiFi 7
The next generation, IEEE 802.11bn, will be called WiFi 8. It focuses on reliability rather than peak speed: steadier throughput at the edge of coverage, lower latency, and smoother roaming between access points. The IEEE is expected to finalize it around 2028. Products labeled WiFi 8 before then are based on draft versions of the standard.
Should you upgrade from WiFi 6 to WiFi 7?
An upgrade makes sense if several of these points apply to you:
- Your internet plan is faster than 1 Gbps, or you plan to switch to one
- You already own several WiFi 7 devices
- You move large files between devices at home, for example to a NAS or a backup drive
- You live in an apartment with many competing networks on 5 GHz
- Video calls, cloud gaming, or VR suffer from lag spikes
- Your current router is WiFi 5 or older and needs replacing anyway
Waiting is reasonable if:
- Your router is WiFi 6 or 6E and your devices are mostly WiFi 6
- Your internet plan is under 1 Gbps
- Your main problem is coverage, not speed near the router
If you are replacing a router anyway, a WiFi 7 model keeps the network ready for the devices you will buy over the next few years. For background on how WiFi works in general, read our introduction to WiFi technology. The Wi-Fi Alliance maintains the list of certified WiFi 7 products.
Summary
- WiFi 7 is IEEE 802.11be. WiFi 6 and WiFi 6E are both IEEE 802.11ax.
- The main upgrades are 320 MHz channels, 4096-QAM, and Multi-Link Operation.
- Real-world gains for a typical 2×2 device are roughly double, and only on 6 GHz with 320 MHz support on both sides.
- Range does not change. Coverage problems need more access points, not a newer standard.
- Everything is backward compatible, so you can upgrade the router and devices at different times.
