Wi-Fi 7 Is Official: Do You Actually Need 46 Gbps Wireless?

The Wi-Fi Alliance officially announced Wi-Fi 7 certification last week at CES, and the marketing numbers are already getting silly. "Up to 46 Gbps." "5x faster than Wi-Fi 6." "The future of wireless." Router manufacturers have started taking pre-orders for products that cost more than my first car.

So let me give you the honest assessment of what Wi-Fi 7 actually is, what it actually does, and whether you should care.

What Wi-Fi 7 Actually Is

Wi-Fi 7 is the consumer name for IEEE 802.11be — the next major revision of the wireless networking standard. It builds on Wi-Fi 6 (802.11ax) and Wi-Fi 6E (which added the 6 GHz band) with three significant new technologies and a handful of smaller improvements.

The headline features:

Multi-Link Operation (MLO). This is genuinely the most important Wi-Fi 7 feature, and it's the one that will make a noticeable difference for real users. MLO allows a device to communicate over multiple frequency bands simultaneously — for example, using both 5 GHz and 6 GHz at the same time on a single connection. Previous Wi-Fi standards forced devices to pick one band at a time. MLO can combine bandwidth, reduce latency through path diversity, and dramatically improve reliability when one band is congested.

320 MHz channels. Wi-Fi 6 maxed out at 160 MHz channels in the 5 GHz and 6 GHz bands. Wi-Fi 7 doubles that to 320 MHz, but only in the 6 GHz band (which has enough total spectrum to accommodate the wider channels). Wider channels mean more raw throughput per connection.

4096-QAM modulation. Wi-Fi 6 uses 1024-QAM, which encodes 10 bits of data per symbol. Wi-Fi 7 jumps to 4096-QAM, encoding 12 bits per symbol — a 20% theoretical throughput improvement at the same channel width. The catch: 4096-QAM requires excellent signal quality to work, so this benefit is mostly realized when devices are close to the access point.

Combined, these features produce the headline number: a theoretical maximum of 46 Gbps.

Why You Will Never See 46 Gbps

The 46 Gbps figure assumes a single device using all available channels in all three bands simultaneously, with maximum modulation, perfect signal quality, and no other devices on the network. It's the wireless equivalent of saying a car can go 200 mph because the speedometer goes that high.

Realistic Wi-Fi 7 throughput in actual homes will look more like this:

• Single device, ideal conditions, near the router: 2-5 Gbps
• Multiple devices, normal home conditions: 500 Mbps - 2 Gbps per device
• Across the house through walls: 200-800 Mbps

That's still impressive, and meaningfully faster than Wi-Fi 6 in many scenarios. But "5x faster than Wi-Fi 6" only applies in narrow benchmark conditions that don't reflect how anyone actually uses Wi-Fi.

Multi-Link Operation Is the Real Story

If you take one thing away from the Wi-Fi 7 hype, it should be MLO. This is the feature that will actually improve daily Wi-Fi experiences, even if you never come close to the headline speeds.

Here's why MLO matters: in a typical home, your Wi-Fi devices constantly battle for airtime on whichever band they're connected to. The 5 GHz band might be congested with your roommate's Netflix stream and your partner's video call. The 6 GHz band might be relatively empty. With Wi-Fi 6, your phone has to pick one band — and switching between them is slow and disruptive.

With MLO, your phone can use both bands simultaneously, automatically routing traffic over whichever has the best conditions at any given moment. Latency drops because there are multiple potential paths for data. Reliability improves because if one band gets congested or interfered with, the other handles the load. The benefit is most noticeable for latency-sensitive applications like gaming and video calls.

For most users, MLO will produce a more obviously improved experience than the raw speed increases.

When You Should Actually Upgrade

Let me be blunt: most people don't need Wi-Fi 7 in 2023, and many people won't need it in 2024 either. Here's my honest upgrade guidance:

Skip Wi-Fi 7 if:

• You have a Wi-Fi 6 or Wi-Fi 6E router that's working well for your devices
• Your internet connection is under 1 Gbps (the bottleneck is your ISP, not your Wi-Fi)
• You don't have any Wi-Fi 7-capable client devices yet (most laptops, phones, and tablets won't get Wi-Fi 7 chips until 2024)
• You're not experiencing congestion or coverage problems with your current setup

Consider Wi-Fi 7 if:

• You have a multi-gigabit internet connection (2 Gbps or faster) and want to make full use of it
• Your home has 30+ connected devices and you're seeing congestion on Wi-Fi 6
• You frequently move large files between local devices and want to take advantage of MLO's reliability improvements
• Your current router is older than Wi-Fi 6 and you were going to upgrade anyway
• You're building a new house and want to wire for the future

The first wave of Wi-Fi 7 routers — products like the TP-Link Archer BE900, Netgear Nighthawk RS700, and ASUS ROG Rapture GT-BE98 — will run $700-1,200. For that money, you can buy a high-end Wi-Fi 6 router and have $400-800 left over for the rest of your home network. Unless you have specific needs that justify the cost, the value calculation favors Wi-Fi 6 or 6E for now.

The Client Device Problem

Here's something that the router marketing won't tell you: a Wi-Fi 7 router does nothing for your phone if your phone doesn't have a Wi-Fi 7 chip. As of January 2023, the only consumer devices with Wi-Fi 7 support are a handful of Android flagships and a few high-end PCs. The iPhone 14 doesn't have it. Most laptops don't have it. Your smart TV definitely doesn't have it.

Wi-Fi 7 devices will become more common throughout 2023 and 2024. By 2025, most premium phones and laptops will likely include Wi-Fi 7 support. Until then, you're paying for capabilities that you can't actually use.

This isn't an argument against Wi-Fi 7 — it's an argument for patience. The router will outlast multiple generations of client devices, so buying it ahead of the device curve isn't crazy. Just don't expect to see the benefits immediately.

My Recommendation

If you're shopping for a new router right now, in early 2023:

• For most homes: Buy a quality Wi-Fi 6 or Wi-Fi 6E router. The TP-Link Archer AX73, ASUS RT-AX86U, or Netgear Nighthawk RAX120 are excellent options in the $200-300 range.
• For power users with gigabit-plus internet: Wi-Fi 6E is the sweet spot — adds the 6 GHz band without the Wi-Fi 7 price premium.
• For early adopters with the budget: Go ahead and buy Wi-Fi 7. You'll be ready when devices catch up, and MLO is a real improvement even with limited client support.

Whatever you do, don't let your router be the bottleneck for your internet connection. A 5-year-old router with a brand new gigabit fiber line is wasted money. But buying a $1,200 Wi-Fi 7 router for a 200 Mbps cable connection is also wasted money.

The right answer is matching your network equipment to your actual usage. Wi-Fi 7 is impressive technology, but for now, it's a solution looking for problems that most people don't have yet.
