Wi-Fi 7 Vs Wi-Fi 6 In Real Apartments: What The Numbers Actually Show

The router sits in the hallway. Between it and the bedroom are two walls, a bookshelf and a microwave. This is the room where every Wi-Fi number gets tested, and it is the room where most of those numbers quietly stop meaning anything.

Manufacturers love to quote peak speeds. A Wi-Fi 6 router is often described as a 9.6 Gbps device. A Wi-Fi 7 router is often described as a 46 Gbps device. Those figures are real in the sense that they appear on specification sheets. They are also the least useful numbers a buyer can look at.

What follows is not a lab report. It is a walk through what those figures measure, why your flat ignores them, and what to check before you spend money on a new router. The short version: the headline number is not a lie, but it is not about your apartment either.

The 46 Gbps Number Lives In A Lab

Start with where these figures come from. Peak throughput is measured under ideal conditions. One client, one router, a clear channel and no neighbours competing for airtime. The number describes the ceiling of the standard, not the floor of your living room.

Wi-Fi 7, known formally as 802.11be, raises that ceiling in a few ways. It doubles the maximum channel width to 320 MHz. It adds a modulation scheme called 4K-QAM, which packs more bits into each transmission. And it introduces multi-link operation, which lets a device use more than one band at once.

The Wi-Fi Alliance began certifying Wi-Fi 7 products in January 2024. Wi-Fi 6E, the version that first opened the 6 GHz band, arrived earlier. Each generation adds capacity at the top end. None of them promises that capacity at the far end of a corridor.

The honest caveat is simple. A 46 Gbps figure assumes conditions almost no apartment can provide. It is a specification, not a forecast. Treat it as an upper bound and it becomes useful. Treat it as a speed you will see and it becomes marketing.

Where The Flat Fights Back

Your apartment does not care about the standard. It cares about walls, distance and neighbours. Radio waves weaken as they pass through dense materials. Brick, concrete and foil-backed insulation are especially unkind. A router in the hallway and a laptop in the bedroom are already working hard before any new standard arrives.

Then there is congestion. In a dense building, dozens of networks share the same channels. Your router waits its turn like everyone else. The 6 GHz band helps here because it is newer and less crowded. But it also has a shorter range and struggles more with walls.

• Walls and doors cut signal strength before speed ever matters.
• Neighbouring networks compete for the same airtime.
• The 6 GHz band is cleaner but travels less far.
• Older devices on the network slow everyone down.

This is where the analogy of a wider pipe starts to break. A wider pipe helps only if water reaches it. In a flat, the bottleneck is usually the path, not the pipe. A Wi-Fi 6 router placed well can beat a Wi-Fi 7 router placed badly.

The Features That Survive A Brick Wall

Not every Wi-Fi 7 improvement is about raw speed. Some of it is about behaving better when the air is crowded. Multi-link operation is the most interesting of these. A device can send data on one band and receive on another, or switch bands when one gets busy.

There is also a feature called puncturing. In older standards, if part of a channel is occupied, the whole channel is often avoided. Wi-Fi 7 can carve out the busy slice and use the rest. In a building full of interference, that is a practical gain rather than a theoretical one.

The 4K-QAM modulation is a different story. It offers roughly a 20 percent gain, but only when the signal is already strong and clean. At the edge of coverage, where most people actually sit, the router falls back to simpler modulation. The gain evaporates exactly where you needed it.

So the useful upgrades are the ones about sharing airtime fairly. The headline upgrades are the ones about moving more data under perfect conditions. Knowing which is which saves money.

Who Actually Notices The Difference

A single person streaming video in a one-bedroom flat will not notice Wi-Fi 7. Video streaming needs a few tens of Mbps, and Wi-Fi 6 already delivers that comfortably. The new standard changes nothing about that experience.

The picture shifts with many devices and heavy local traffic. A household with several people, a home server and large file transfers can benefit. So can anyone backing up a laptop to a network drive. These are the cases where extra capacity and better airtime sharing earn their keep.

Gaming and video calls care about latency and stability more than peak speed. Wi-Fi 7's multi-link features can help there, but the improvement is modest and depends on the client device. A phone or laptop that supports only Wi-Fi 6 will not use the new tricks.

This is the part most buyers miss. The router is only half the pair. If your devices are older, a Wi-Fi 7 router mostly runs in compatibility mode. You pay for the ceiling and live on the floor.

The Awkward Bits Nobody Puts On The Box

Two practical points deserve attention. The first is that Wi-Fi 7 routers are still relatively expensive. The second is that the 6 GHz band, where much of the benefit lives, is regulated differently around the world. Availability and allowed power vary by country.

There is also the question of wired backhaul. If you can run a cable to a second access point, that often beats any single router upgrade. A mesh system with a wired link solves the wall problem directly. No standard fixes physics, but cable sidesteps it.

The less glamorous answer is that placement and wiring still matter most. A router high up, central and unobstructed will outperform a better router hidden in a cupboard. This was true before Wi-Fi 6 and it remains true with Wi-Fi 7.

None of this makes Wi-Fi 7 pointless. It makes it situational. The technology works. The question is whether your flat is the situation it was built for.

Final Thoughts On What To Try

Before buying anything, check the Wi-Fi specification of the devices you actually use. Look for "Wi-Fi 7" or "802.11be" in the spec sheet of your phone and laptop. If neither supports it, fix placement first: move the router out of the cupboard and into the open, roughly central in the flat. Then test the speed in the room where you actually sit. If that number is fine, you have your answer.
