WiFi 7 vs WiFi 6: What Is the Difference?

The demands on wireless networks are growing fast. With IoT connections expected to reach 20.1 billion this year¹ and global data creation projected to hit 394 zettabytes by 2028,² it’s more important than ever for network infrastructure to keep pace with digital transformation trends.

That’s where WiFi 7 comes in. WiFi 7 represents the next wireless evolution, with analysts predicting it will comprise 10% of all WiFi access points shipped in 2025.³ But before making a move to this exciting new technology, it’s important to understand the difference between WiFi 6 and WiFi 7 – and if an upgrade is the right choice for your enterprise.

In this guide, we’ll break down WiFi 6 vs WiFi 7 and explore the benefits of each to help you prepare for the shift.

What Is WiFi 7?

WiFi 7, or IEEE 802.11be, is the next-generation wireless standard designed to improve network performance over previous WiFi versions. While WiFi 6 (802.11ax) focused on boosting efficiency in high-density environments, WiFi 7 takes those improvements further by supporting faster speeds and more simultaneous connections – all with better spectrum utilization.

Some key features of WiFi 7 are:

• Max theoretical speed of up to 46 Gbps, compared to 9.6 Gbps with WiFi 6.
• Wider channel bandwidth of 320 MHz vs. WiFi 6, which only supports up to 160 MHz.
• 16x16 MU-MIMO support, up from 8x8 in WiFi 6.
• Multi-Link Operation (MLO) so that devices can send data across multiple bands at once.
• Improved efficiency and reduced latency for real-time applications like VR and 4K/8K streaming.

These enhancements position WiFi 7 as a future-ready solution for businesses looking to support increasingly connected environments.

WiFi 6 vs WiFi 7: Performance Comparison

So, what exactly is the main difference between WiFi 6 and 7? Check out our comparison chart below to see how they stack up:

Overall, WiFi 7 introduces major improvements in speed, channel flexibility, and simultaneous data transmission. For environments with a lot of network-connected devices or real-time apps, these changes can make a huge difference in performance.

What Are the Benefits of WiFi 7 vs WiFi 6?

Choosing between WiFi 6 and WiFi 7 will depend on your current business needs and plans for the future. Here's a closer look at the benefits of WiFi 7 vs WiFi 6:

Increased Speed and Bandwidth

WiFi 7’s support for 320 MHz channels and 4K QAM modulation means it can transmit more data at faster rates. This makes it ideal for:

• High-definition video conferencing
• Augmented/virtual reality applications
• Large file transfers or backups
• Crowded device environments like corporate campuses

WiFi 7 lets users experience consistently better network performance, even during peak usage times, resulting in vastly improved team efficiency and productivity.

Improved Network Efficiency

With Multi-Link Operation (MLO), WiFi 7 devices can transmit and receive data across multiple bands (2.4GHz, 5GHz, and 6GHz) at once. This reduces latency for time-sensitive apps like video calls, which means users can experience fewer delays and more responsive connections.

WiFi 7 also offers better network load balancing. It intelligently distributes traffic across available frequency bands to prevent any single band from becoming congested, creating a more stable environment for mission-critical applications.

Enhanced Support for Time-Sensitive Applications

WiFi 7 offers more consistent low-latency performance for organizations that rely on time-sensitive applications – think real-time voice, video, or interactive tools. This is essential for:

• Unified Communications (UCaaS): WiFi 7 provides clearer voice quality and synchronized video so teams can collaborate without the frustration of audio delays or video freezes that hamper productivity and create meeting fatigue.
• Video Surveillance: WiFi 7’s increased bandwidth and reduced latency support higher-resolution cameras and more consistent streaming, improving security and monitoring capabilities.
• Point-of-Sale Systems: The reduced latency and stronger reliability offered by WiFi 7 ensure payment processing happens instantly and minimizes transaction failures, creating a smoother experience for customers and staff.

Better Performance in Congested Environments

While WiFi 6 introduced technologies like OFDMA and MU-MIMO to allow multiple users to share channels, WiFi 7 expands these capabilities. These enhancements provide better support for dense deployments where hundreds or thousands of devices need simultaneous access, so enterprises with high device concentrations will notice substantially improved performance.

What’s the Difference Between WiFi 6 and 7 for Businesses?

From a business perspective, the difference between WiFi 6 and WiFi 7 isn’t just about speed; it’s about readiness. 

WiFi 6 is ideal if:

• You recently upgraded your wireless infrastructure.
• Your environment has moderate to high device density.
• You need reliable performance but don’t yet require extreme throughput.

WiFi 7 may be better if:

• You’re designing a new wireless network with future growth in mind.
• You plan to support AR/VR, 8K video, or high-volume data traffic.
• Your users demand high-speed, low-latency access at all times.
• You're building a wireless-first or hybrid network strategy.

Both options are improvements over older WiFi standards, so make sure to align your choice with your business's specific needs rather than simply chase the latest technology.

Wireless Site Surveys: The Key to a Successful WiFi 6 or WiFi 7 Deployment

Whether you're installing WiFi 6 today or planning a future upgrade to WiFi 7, a WiFi survey is essential for success. 

A wireless site survey ensures:

• Correct access point placement for maximum coverage
• Minimal interference and channel overlap
• Right-sizing your AP investment based on usage needs
• Planning for aesthetics, mounting options, and bandwidth demand

Site surveys help businesses build more efficient wireless networks – without the guesswork. Organizations that skip this step tend to face issues like coverage gaps, performance issues, and unnecessary hardware costs.

5 Steps To Prepare for the Shift From WiFi 6 to WiFi 7

You don’t need to rip and replace your infrastructure to prepare for WiFi 7. In most cases, businesses can take an incremental approach:

1. Evaluate your existing APs and cabling to ensure they support upcoming upgrades.
2. Use WiFi surveys to identify current performance gaps.
3. Prioritize high-traffic or problem areas for pilot WiFi 7 deployments.
4. Choose compatible access points that support WiFi 6E today and WiFi 7 in the future.
5. Build a scalable wireless architecture that supports multi-band, high-density usage.

Investing in wireless now with the future in mind can help your organization reduce costs and network disruptions later.
