How is Wi-Fi 7 Different from Wi-Fi 6/6E?- Welcome to MERCUSYS

Wi-Fi 7, the latest Wi-Fi standard, brings us into a new era of network connectivity, offering faster speeds, reduced interference, and greater efficiency—marking a significant leap forward from Wi-Fi 6E. But is Wi-Fi 7 truly a game-changer? Do we really need it? Let’s dive in and find out.

Wi-Fi 7 Key Upgrades*

Broader bandwidth—doubled up to 320 MHz*
Greater throughput—4K-QAM
Improved reliability and lower latency—Multi-Link Operation (MLO)
Enhanced signal anti-interference capability—Preamble Puncturing
Better resource utilization—Multi-RUs

*All upgrades are only compatible with Wi-Fi 7 models.

*Dual-band Wi-Fi 7 models do not support 320 MHz.

Doubled Bandwidth

Wi-Fi 7 fully capitalizes on the 6 GHz spectrum, doubling bandwidth compared to Wi-Fi 6/6E. By extending the channel width to 320 MHz, it facilitates significantly more simultaneous transmissions at the highest possible speeds.

Higher-Order 4K-QAM

Wi-Fi 7 enhances the modulation order from Wi-Fi 6/6E’s 1024-QAM to 4096-QAM (also known as 4K-QAM). QAM, quadrature amplitude modulation, is a standard for measuring the amount of data that can be encoded onto a radio signal. With 4K-QAM modulation, each symbol carries 12 bits instead of 10, boosting transmission rates by 20% and increasing overall throughput. Combined with a wider 320 MHz bandwidth, these advancements enable throughput speeds up to 46 Gbps.

Multi-Link Operation (MLO)

Traditional Wi-Fi devices use a single link (the 2.4 GHz, 5 GHz, or 6 GHz band) to transmit data at the same time. Wi-Fi 7 offers efficient and flexible multi-link options, allowing traffic to be distributed across three bands or quickly shifted from a congested band to a less crowded one. By allowing devices to connect to the 2.4 GHz, 5 GHz, and 6 GHz bands simultaneously, Wi-Fi 7 increases throughput, reduces latency, and improves reliability for online gaming, AR/VR, remote offices, and cloud computing.

Preamble Puncturing

Traditionally, busy channels limited the full utilization of frequency bands as data could only be transmitted through the primary channel. However, with the introduction of Preamble Puncturing, interference can now be selectively blocked. Unlike Wi-Fi 6/6E where any interference would disrupt the entire channel, this new technique enables the system to isolate and block only the affected portion of a channel, while continuing to use the rest for data transfer. By leveraging preamble puncturing to circumvent interference, Wi-Fi 7 can utilize wider channels even in challenging environments, ensuring uninterrupted and efficient data transmission.

Multi-RUs

With Wi-Fi 6/6E, a user can only use one resource unit (RU, the smallest unit of bandwidth in Wi-Fi communication) at a time. Imagine packing all your items in a small box. When transmitting large amounts of data, this “small box” could be inefficient and require multiple trips. Wi-Fi 7 introduces the Multiple Resource Unit (MRU), addressing congestion by assigning multiple RUs to a single user. This allows users to select the optimal size and number of RUs, enhancing efficiency, improving resource allocation, and boosting transmission stability.
