Wi-Fi 8 vs. Wi-Fi 7: What’s New and Is It Worth Upgrading?

Despite the promise of high speeds from Wi-Fi 7, many users still encounter connectivity issues like dropped connections and inconsistent performance, especially in congested areas. This raises the question: Will Wi-Fi 8 finally resolve these real-world frustrations?

Historically, each new Wi-Fi standard has emphasized theoretical speed increases. While speeds have indeed grown, practical experience often falls short due to interference, network congestion, and the increasing number of connected devices. Wi-Fi 7 (802.11be), or Extremely High Throughput (EHT), introduced innovations like Multi-Link Operation (MLO) and wider channels. However, Wi-Fi 8 (802.11bn) marks a significant shift, prioritizing reliability and efficiency over sheer speed.

This article explores how Wi-Fi 8 builds on Wi-Fi 7, highlighting its advancements in reliability, efficiency, and network management. We will also help you determine if an upgrade is worthwhile for your specific needs, whether you're an enterprise IT manager, a smart home enthusiast, or simply seeking a more stable connection.

Wi-Fi 8 vs. Wi-Fi 7

Technical Comparison: Wi-Fi 7 vs. Wi-Fi 8

Let's examine the core specifications of both Wi-Fi 7 and the upcoming Wi-Fi 8 to understand their differences and Wi-Fi 8's innovations.

Core Specifications: A Detailed Look

Wi-Fi standards, defined by the IEEE, are designed to meet evolving wireless communication demands. Wi-Fi 7 (802.11be), also known as Wi-Fi 7 EHT, focused on significant speed gains over Wi-Fi 6/6E.

Wi-Fi 7 (802.11be):

• Maximum Theoretical Throughput: Up to 46 Gbps (under ideal lab conditions).
• Channel Bandwidth: Supports up to 320 MHz, primarily in the 6 GHz band.
• Modulation: 4096-QAM (12 bits per symbol), packing more data into each transmission.
• Spatial Streams: Up to 16x16 MU-MIMO for simultaneous device communication.
• Key Feature: Multi-Link Operation (MLO): Allows devices to send and receive data across multiple frequency bands (2.4 GHz, 5 GHz, 6 GHz) simultaneously, reducing latency and increasing throughput.
• Frequency Bands: Operates across 2.4 GHz, 5 GHz, and 6 GHz bands.

Now, let's look at Wi-Fi 8 (802.11bn), which is still under development but has a clear direction. While it maintains high theoretical speeds, its true innovation lies in optimizing these speeds for real-world scenarios.

Wi-Fi 8 (802.11bn):

• Maximum Theoretical Throughput: Aggregate theoretical speeds can reach 100 Gbps, with individual device speeds typically ranging from 23–46 Gbps (similar to Wi-Fi 7). The emphasis is on consistent delivery of these speeds in challenging environments.
• Channel Bandwidth: Continues to support 320 MHz channels, potentially with more flexible aggregation.
• Modulation: Introduces 8192-QAM, theoretically increasing throughput by 25% over 4096-QAM.
• Spatial Streams: Expected to refine MU-MIMO and introduce more sophisticated multi-AP coordination.
• Integrated mmWave: Planned integration of millimeter-wave (mmWave) frequencies for high-bandwidth, short-range applications.
• Distributed MLO: An evolution of Wi-Fi 7's MLO, enabling more sophisticated multi-AP coordination.
• Key Focus: Ultra-High Reliability (UHR), efficiency, and multi-AP coordination, making the network smarter and more resilient.

Technical Comparison: Wi-Fi 7 vs. Wi-Fi 8

While both standards use the 2.4, 5, and 6 GHz bands, Wi-Fi 8 adds mmWave and advanced multi-AP features designed for dense environments. As one expert noted, "Wi-Fi 8 aims to accommodate the increasing demands of high-speed broadband, ensuring seamless connectivity for multi-gigabit networks while addressing the very real challenges of interference and congestion."

Revolutionary Features in Wi-Fi 8

Wi-Fi 8 introduces features that fundamentally change how wireless networks operate, focusing on reliability and managing complexity, rather than just incremental speed boosts.

• Coordinated Spatial Reuse (Co-SR): This feature optimizes how multiple Wi-Fi access points (APs) in close proximity communicate. Instead of interfering with each other, Co-SR allows APs to dynamically adjust transmit power and coordinate transmissions to minimize interference. This leads to more efficient reuse of wireless channels, boosting network capacity and reducing contention. MediaTek's whitepaper suggests 15–25% efficiency gains.
• Coordinated Beamforming (Co-BF): Building on existing beamforming technology, Co-BF enables multiple APs to work together to create a stronger, more focused signal ("super-beam") to devices. This strengthens the signal to active devices and significantly reduces interference to others, especially in mesh networks or public spaces. This coordinated approach can boost throughput by 20–50% in such setups.
• Dynamic Sub-Channel Operation (DSO): Wi-Fi 8 intelligently assigns smaller sub-channels to devices based on their immediate needs, optimizing spectrum usage. For instance, a device sending a small data packet might only use a narrow sub-channel, leaving the rest of the bandwidth free. This dynamic allocation can potentially increase throughput by up to 80%.
• Enhanced Modulation Coding Scheme (MCS): This improves connection robustness. When signal quality degrades (e.g., moving further from the AP), the system can seamlessly switch to a more robust (though slower) modulation scheme without dropping the connection entirely. This reduces sudden drops in data rates and improves user experience.
• Multi-AP Coordination: This overarching theme extends Wi-Fi 7’s Multi-Link Operation to multiple access points. APs can now work cohesively to manage interference, share load, and seamlessly hand off devices. This is a game-changer for large enterprise networks, smart factories, and complex smart homes, ensuring consistent coverage and performance.

Consider a busy office with many video calls and large file transfers. Wi-Fi 7 might experience bottlenecks due to AP interference. Wi-Fi 8's Co-SR and Co-BF would actively mitigate this, ensuring stable connections. In a smart home with numerous IoT devices, Multi-AP Coordination and Co-SR would reduce dropped connections and keep every device reliably online.

It's important to note that some advanced Wi-Fi 8 features might be optional or proprietary to specific vendors in early devices, potentially leading to inconsistent real-world benefits.
