Over the years, wireless technology has evolved and advanced, enabling us to stay connected in ways we never thought were possible. The evolution of wireless technology has been driven by the need for faster and more reliable connectivity.

With each generation, wireless technology has become faster, more efficient, and capable of handling larger amounts of data. This has opened a world of possibilities and has revolutionized the way we live, work, and communicate. As we stand on the precipice of the next chapter in wireless evolution, Wi-Fi 7 has emerged as the technology that pioneers advanced connectivity.

Consumers and enterprises alike are increasingly drawn to Wi-Fi 7 as they are well-versed with its practical benefits, particularly in terms of high reliability and low latency. Consumers seek reliable broadband networks for a seamless digital experience, while enterprises view Wi-Fi 7 as a solution for enhanced user experiences, better network capacity, and a stable infrastructure capable of supporting more enterprise and client devices.

With Wi-Fi 7, prepare yourselves for speeds that’ll make downloading movies feel like flipping a page, latency so low that it seems like playing games on the server itself, and a signal so strong it’ll pierce through walls.

But what exactly is this Wi-Fi 7?

Wi-Fi 7 Unique Capabilities: A Closer Look

Wi-Fi 7, also known as IEEE 802.11be Extremely High Throughput (EHT), is the next generation of wireless technology designed to provide exceptionally high speeds and improved efficiency for a wide range of devices. Wi-Fi 7 operates across all three frequency bands (2.4 GHz, 5 GHz, and 6 GHz) to make optimal use of available spectrum resources. The primary objective of Wi-Fi 7 is to deliver faster and more reliable wireless connections.

The unique capabilities of Wi-Fi 7 are far-reaching and will have a profound impact on various aspects of our lives. Envisioned to address the growing demands, Wi-Fi 7 introduces a range of features such as higher speeds, improved efficiency and enhanced capabilities.

Double the Bandwidth, Double the Speed

Up to 320 MHz on 6 GHz

Doubling the bandwidth compared to the previous generation, Wi-Fi 7 maximizes the potential of the 6 GHz band by allowing up to 320 MHz channel width. This expansion facilitates a higher number of concurrent transmissions, leading to significantly faster speeds.

Double the Streams, Double the Capacity

16 × 16 MU-MIMO

Enhancing capacity to keep up with the rising demands of numerous Wi-Fi devices, Wi-Fi 7 employs 16×16 MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology. This advancement involves doubling the number of spatial streams from 8 to 16, effectively doubling the theoretical physical transmission rate when compared to Wi-Fi 6. The increased stream count in Wi-Fi 7 ensures that each device enjoys ample bandwidth, promoting smooth and efficient operation.

Packs 120% Data for Higher Speeds

4K-QAM

In its pursuit of enhanced peak rates, Wi-Fi 7 incorporates an advanced modulation scheme: 4096-QAM. This upgrade allows each symbol to convey 12 bits instead of 10 bits, resulting in a 20% increase in theoretical transmission rates compared to Wi-Fi 6’s 1024-QAM. The heightened transmission rate contributes to enhanced efficiency, enabling users to achieve superior data transmission. Now, you can enjoy seamless viewing of 4K/8K videos, engage in lag-free gaming on a grand scale, or effortlessly live stream from your home computer. The implementation of 4096-QAM marks a significant improvement, making streaming experiences even more remarkable.

Makes Full Use of Every Resource

Multi-RU

In Wi-Fi 6, each user is restricted to sending or receiving frames on a designated resource unit (RU), imposing notable constraints on spectrum resource scheduling flexibility. To address this limitation and enhance spectral efficiency, Wi-Fi 7 introduces the capability to assign multiple RUs to a single user and merge RUs to achieve heightened transmission efficiency.

No Waste, No Congestion

Preamble Puncturing

In the past, congested channels resulted in incomplete utilization of bands, restricting data transmission through the primary channel only. However, with the introduction of Preamble Puncturing, interference can be effectively blocked, enabling the use of more channels for data transmission.

Higher Speed, Lower Latency, More Reliable

Multi-Link Operation

Conventional Wi-Fi devices typically rely on a single link for data transmission. With various Multi-link Operation (MLO) Modes, Wi-Fi 7 allows devices to employ multi-link aggregation for enhanced throughput, reduced latency, and increased reliability. Alternatively, devices can utilize multi-link seamless dynamic switching to achieve effective load balancing and lower latency.
