Wi-Fi 4, 5, 6, 6E, and 7: The Difference Between the Standards and What It Means for Your Network

When you buy a new router or smartphone, you will definitely see inscriptions like this on the box Wi-Fi 6 or 802.11axBut what do they mean in practice? Why is one standard faster than another, while another is more stable over long distances? And is it worth paying extra for? Wi-Fi 7, if you only have a couple of devices?

In this article we will look at all current Wi-Fi standards - from obsolete 802.11n (Wi-Fi 4) to the latest 802.11be (Wi-Fi 7). You'll learn how they affect internet speed, network coverage, device compatibility, and even battery life. Finally, you'll find practical recommendations on which standard to choose for your home, office, or gaming room.

What are Wi-Fi standards and why are they needed?

Wi-Fi standards are a set of technical requirements that define, How devices communicate wirelesslyThey are being developed by the organization IEEE (Institute of Electrical and Electronics Engineers), and they are designated as 802.11 with the addition of letters (a, b, g, n, ac, ax, be).

Since 2018, for the convenience of users, we have introduced digital marking: Wi-Fi 4 (instead of 802.11n), Wi-Fi 5 (instead of 802.11ac) and so on. This simplified the choice of equipment, but did not eliminate the old designations—they are still used in router settings and device specifications.

• 📡 Data transfer rate — maximum network throughput (measured in Mbit/s or Gbit/s).
• 📶 Frequency range - 2.4 GHz (long-range, but congested) or 5/6 GHz (fast, but less coverage).
• 🔄 Modulation technologies - how data is encoded for transmission (e.g. OFDMA or MU-MIMO).
• 🔋 Energy efficiency — how the standard affects the battery consumption of connected devices.

Each new standard solves the problems of the previous one: increases speed, reduces delays (ping), improves performance in interference conditions. But there's a catch: Even if your router supports Wi-Fi 6E and your smartphone only supports Wi-Fi 5, the connection will work on the weakest standard of the pair..

Wi-Fi 4 (802.11n): the basic standard for budget devices

Wi-Fi 4 (or 802.11n) appeared in 2009 and became the first standard that supported dual-band operation — at 2.4 GHz and 5 GHz frequencies. This was a breakthrough: previously, devices could only operate at 2.4 GHz, where interference from microwaves, Bluetooth devices, and neighbors was constant.

Maximum theoretical speed Wi-Fi 4 — 600 Mbps (in real conditions - 150-300 Mbps). This is enough for watching videos in Full HD, but it is no longer enough for 4K or online games. The main disadvantages of the standard:

• 🐢 Low speed compared to modern standards.
• 📡 Strong interference on 2.4 GHz (especially in apartment buildings).
• 🔌 Lack of support MU-MIMO — the router can exchange data with only one device at a time.

⚠️ Attention: If your router only works in standard 802.11n, it won't be able to provide internet speeds above 100–150 Mbps, even with a 1 Gbps plan. This is a limitation of the standard itself, not the provider.

Today Wi-Fi 4 It is considered obsolete, but it can still be found in budget routers (for example, TP-Link TL-WR840N), smart light bulbs, and some printers. If you have a plan up to 100 Mbps and few devices on the network, this standard may be sufficient. But for modern tasks, it's better to consider at least Wi-Fi 5.

Wi-Fi 5 (802.11ac): The Gold Standard for the Home

Wi-Fi 5 (or 802.11ac) debuted in 2013 and became the first standard to focused on the 5 GHz frequencyThis allowed for a significant increase in speed and a reduction in interference. The theoretical maximum is 6.9 Gbps (in reality - 500-1000 Mbit/s), which is enough for 4K-video, online games and simultaneous operation of several devices.

Key improvements Wi-Fi 5 compared to Wi-Fi 4:

• 🚀 Support wide channels (up to 160 MHz versus 40 MHz for Wi-Fi 4).
• 🔄 Technology MU-MIMO — the router can simultaneously transmit data to several devices (up to 4 streams).
• 📶 Best performance on 5 GHz, where there is less interference.
• 🔋 A more energy-efficient protocol Beamforming (directional signal transmission).

This is the most balanced standard today: it is supported almost all devices (smartphones, laptops, TVs), offers high speed and does not require large expenditures. Routers with Wi-Fi 5 (For example, ASUS RT-AC68U or Xiaomi Mi Router 4A Gigabit) remain popular for home use.

⚠️ Attention: If your router supports Wi-Fi 5, but you are connecting to a network at 2.4 GHz, the speed will be limited by the capabilities 802.11n (Wi-Fi 4). To get the most out of the standard, use the 5 GHz band.

Set up a separate 5 GHz network in the router control panel

Make sure the channel width is set to 80 MHz (or 160 MHz if supported)

Disable legacy standards (802.11b/g) in your wireless network settings

Connect a device that supports 802.11ac (check specifications)-->

Wi-Fi 6 (802.11ax): A Revolution for Multitasking

Wi-Fi 6 (or 802.11ax) was released in 2019 and was a response to the growing number of connected devices in homes and offices. Its main feature is efficient operation under high load conditionsWhile the router might previously struggle to connect to 10+ devices, it can now handle 50+ without any loss of speed.

What's new in Wi-Fi 6:

• 🎯 OFDMA — splitting the channel into subchannels for simultaneous data transmission to several devices (ideal for smart homes).
• 🔄 Enhanced MU-MIMO - support for up to 8 streams (versus 4 in Wi-Fi 5).
• 📈 BSS Coloring — reduction of interference from neighboring networks.
• 🔋 Target Wake Time (TWT) — devices "sleep" when not transmitting data, saving battery.

Theoretical speed Wi-Fi 6 — to 9.6 Gbps, but in reality you'll get 1–2 Gbps (depending on devices and conditions). The main advantage of the standard isn't speed, but stability: even with a large number of connected gadgets, the ping remains low, and the video does not "lag".

Routers with Wi-Fi 6 (For example, TP-Link Archer AX6000 or Netgear Nighthawk RAXE500) are more expensive, but are worth it in homes with a lot of devices (smartphones, laptops, smart devices, game consoles). If you have a 500+ Mbps plan or you frequently play online games, switching to Wi-Fi 6 makes sense.

Wi-Fi 6E: Extended 6 GHz Range

Wi-Fi 6E - this is not a new standard, but Wi-Fi 6 expansion with additional range support 6 GHzThis range was previously banned for civilian use, but since 2020–2021 it has been opened in most countries (including Russia). The main advantage of 6 GHz is no interference: No old devices, microwaves or congested channels here.

What does it give? Wi-Fi 6E:

• 🆕 14 additional channels 80/160 MHz wide (versus 2–3 at 5 GHz).
• 🚀 High throughput — up to 2 Gbit/s on one stream.
• 🔒 Less interference - ideal for dense development.
• 📱 Support for modern devices (iPhone 15, Samsung Galaxy S23, laptops with Intel Wi-Fi 6E).

However, 6 GHz has its downsides:

• 📉 Less coverage — the signal penetrates walls worse than at 5 GHz.
• 💰 Expensive routers (For example, ASUS RT-AX89X or Netgear RAXE300).
• 🔌 Not all devices support 6 GHz. (especially budget smartphones and TVs).

⚠️ Attention: Before purchasing a router with Wi-Fi 6E Check if the 6 GHz band is permitted in your country. In some regions, it may be restricted or require special permission.

Wi-Fi 6E is ideal for:

• 🎮 Gamers (low ping, no lags).
• 🏢 Offices with a large number of devices.
• 📺 Streaming 8K-video or VR.

Wi-Fi 7 (802.11be): The Future Is Here

Wi-Fi 7 (or 802.11be) is the newest standard, the final specification of which was approved in early 2026. It promises revolutionary improvements:

• 🚀 Speed ​​up to 46 Gbps (theoretically).
• 🔄 320 MHz channels (versus 160 MHz in Wi-Fi 6).
• 🎯 Multi-Link Operation (MLO) - simultaneous use of multiple bands (2.4, 5 and 6 GHz) to increase speed and reliability.
• 📡 4K-QAM - denser signal modulation (more data in one packet).

Real benefits Wi-Fi 7:

• 🎮 Ping up to 1 ms — ideal for cloud gaming and VR.
• 📺 8K streaming without buffering.
• 🏠 Stable operation of 100+ devices in a smart home.

However, there are some nuances:

• 💸 Very expensive routers (from 30,000 rubles, for example, TP-Link Archer BE900).
• 📱 Few supported devices (only flagship smartphones from 2026-2026, for example, Samsung Galaxy S24 Ultra).
• 🔧 Firmware with MLO support is required. (not all routers can do this out of the box).

Today Wi-Fi 7 - This investment in the futureIf you already have devices that support it and a 1+ Gbps plan, you can consider purchasing it. Otherwise, it's best to wait 1-2 years until the standard becomes widespread and prices drop.

What devices already support Wi-Fi 7?

Smartphones: Samsung Galaxy S24 Ultra, iPhone 15 Pro (partially), Xiaomi 14 Pro.
