In this article, we'll dive deep into the fascinating world of WiFi 6 and WiFi 7, comparing their strengths and weaknesses when it comes to bouncing signals through walls. We will try to explain what affects the signal penetration and give some advice about it. Get ready to explore the science behind your wireless connection and discover which technology might be the champion for your home or office. Let's get started!

Understanding the Basics: WiFi 6 and WiFi 7

Before we jump into the wall penetration showdown, let's get acquainted with our contenders. WiFi 6, also known as 802.11ax, is the current generation of Wi-Fi technology, and it's already a significant leap forward from its predecessor. It boasts improvements in speed, efficiency, and capacity, making it a solid choice for modern homes and businesses. Think of it as the experienced veteran, having undergone rigorous training and already achieving great results.

Now, enter WiFi 7, or 802.11be, the rising star. This is the next generation of Wi-Fi, still in its early stages of deployment, with the promise of taking things to a whole new level. WiFi 7 aims to deliver even faster speeds, lower latency, and greater capacity, building upon the foundation laid by WiFi 6. It's like the new recruit, full of potential and eager to prove itself on the battlefield.

Both WiFi 6 and WiFi 7 use a combination of technologies to improve performance, including:

• OFDMA (Orthogonal Frequency Division Multiple Access): This allows the router to communicate with multiple devices simultaneously, increasing efficiency.
• MU-MIMO (Multi-User Multiple-Input Multiple-Output): This allows the router to send data to multiple devices at the same time, boosting overall network capacity.
• 1024-QAM (Quadrature Amplitude Modulation): This allows for more data to be packed into each signal, leading to higher throughput.

But the main difference between these two technologies is the frequency band and channel width that affect wall penetration. So let's talk about them.

The Physics of Wall Penetration: What You Need to Know

Alright, let's get into the nitty-gritty of how Wi-Fi signals interact with walls. The ability of a Wi-Fi signal to penetrate walls depends on several factors, but the primary ones are the frequency band and the materials the walls are made of. You can compare it to the behavior of light; think of how it can easily pass through glass, but it's blocked by a solid metal. Similarly, Wi-Fi signals behave differently depending on the materials they encounter.

• Frequency Bands: Wi-Fi signals operate on different frequency bands, most commonly 2.4 GHz and 5 GHz. A higher frequency (like 5 GHz) can carry more data but has a shorter range and struggles more with wall penetration. Lower frequencies (like 2.4 GHz) have a longer range and penetrate walls better but offer slower data transfer speeds. WiFi 7 introduces the 6 GHz band, which we will consider later.
• Wall Materials: The materials that walls are made of play a crucial role. Solid materials like concrete, brick, and metal are the worst offenders, significantly attenuating Wi-Fi signals. Drywall, wood, and glass generally allow signals to pass through with less interference. The thicker the wall and the more dense the materials, the weaker the signal will be on the other side. This is also why WiFi is affected by distance. The signal must cover a bigger distance, so it will get weaker.

When a Wi-Fi signal encounters a wall, it can be:

• Absorbed: Some of the signal's energy is absorbed by the wall material, weakening the signal.
• Reflected: The signal bounces off the wall, potentially causing interference.
• Refracted: The signal bends as it passes through the wall, which can also affect its strength.

So, in order to improve the signal penetration, you must deal with these factors. But how do Wi-Fi generations do it differently?

WiFi 6 vs. WiFi 7: Wall Penetration Showdown

Now for the big question: how do WiFi 6 and WiFi 7 compare in terms of wall penetration? While both technologies are built on similar foundations, they have some key differences that affect their performance.

• WiFi 6: It mainly operates on 2.4 GHz and 5 GHz bands. The 2.4 GHz band provides better wall penetration due to its lower frequency, making it suitable for reaching devices in rooms further away from the router. The 5 GHz band offers faster speeds but can struggle with walls.
• WiFi 7: It includes the 2.4 GHz, 5 GHz, and the new 6 GHz bands. The 6 GHz band provides even more capacity and can offer faster speeds, but it will likely have the same or slightly worse wall penetration characteristics as the 5 GHz band. In the same way as WiFi 6, the 2.4 GHz band in WiFi 7 will be your best friend if you need to pass through several walls. This is because it has a smaller frequency. However, WiFi 7 has a Multi-Link Operation (MLO) feature that can use multiple bands at the same time, which, in theory, can improve overall wall penetration by combining the strengths of different frequency bands.

In terms of raw wall penetration capabilities, WiFi 6 and WiFi 7 are fairly similar. Both technologies still rely on the laws of physics, so the frequency band is the most important factor. The 2.4 GHz band will always provide better wall penetration than the 5 GHz or 6 GHz bands. However, with the new technologies added in WiFi 7, you could improve signal coverage.

Practical Tips for Improving Wall Penetration

Okay, guys, here are some actionable tips to improve your Wi-Fi signal's ability to penetrate walls: These strategies can be applied to both WiFi 6 and WiFi 7 networks.

• Router Placement is Crucial: Place your router in a central location, as high up as possible, and away from obstructions. Try to avoid placing it near walls, mirrors, or metal objects that can reflect or absorb the signal.
• Use the 2.4 GHz Band: If wall penetration is your priority, stick with the 2.4 GHz band on your router. Remember, it offers better range and can handle walls more effectively.
• Optimize Router Settings: Ensure your router is using the latest firmware and that you've configured your Wi-Fi channel correctly. Channel optimization can help reduce interference from other Wi-Fi networks in your area.
• Consider a Mesh Wi-Fi System: If you have a large home or significant wall obstructions, a mesh Wi-Fi system can be a game-changer. These systems use multiple access points to create a seamless Wi-Fi network throughout your home.
• Use Range Extenders (with Caution): Range extenders can help boost your Wi-Fi signal, but they can also reduce overall network speed. Place them strategically and avoid extending the signal through multiple walls.
• Inspect Your Walls: Some materials are Wi-Fi unfriendly. If you're building a new home or renovating, consider using materials that are more Wi-Fi-friendly. If you can, check the wall materials to see if they're the ones causing a problem.

Remember, no matter what tech you use, you can always improve the signal in your home. The tips above should help you with it.

The Future of Wi-Fi: What's Next?

As Wi-Fi technology continues to evolve, we can expect to see further improvements in wall penetration. Future generations of Wi-Fi might leverage new techniques, like more advanced beamforming or AI-powered optimization, to improve signal strength and coverage. For now, both WiFi 6 and WiFi 7 offer significant advantages over older technologies. They have different features, so one can be better than the other, depending on the environment.

Conclusion: Making the Right Choice

So, which technology wins the wall penetration battle? The answer depends on your specific needs and environment. If you prioritize speed and have a relatively open space, WiFi 6 or WiFi 7 on the 5 GHz or 6 GHz band could be sufficient. However, if you have a multi-story home with many walls, the 2.4 GHz band is your best bet for better penetration, regardless of the Wi-Fi generation. Remember, the best approach is to choose the technology that best fits your environment and optimizes the tips that we have given you.
