Wi-Fi 7, also known as IEEE 802.11be or Extremely High Throughput (EHT), is the developing standard for the next generation of Wi-Fi technology, aiming to provide faster and more efficient wireless connectivity.

Key features of Wi-Fi 7:

1. Larger Channel Sizes

Wi-Fi 7 doubles the bandwidth by increasing channel width from 160 MHz to 320 MHz. Wider channels mean higher data transfer speeds and increased simultaneous data transmission capability.

2. Multi-Link Operation (MLO)

MLO allows devices to aggregate two or more channels from different frequency bands (6/5/2.4 GHz), enabling simultaneous transmission and reception across frequency bands, particularly useful in scenarios requiring low latency and greater bandwidth, such as video conferencing and augmented reality gaming.

3. 4096-QAM Modulation

Wi-Fi 7 offers enhanced 4096-QAM modulation, achieving higher speeds through more efficient data encoding techniques.

4. MU-MIMO

Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) enables Wi-Fi routers to communicate simultaneously with multiple devices, improving wireless connection efficiency. Compared to Wi-Fi 6, Wi-Fi 7 increases the number of spatial streams from 8 to 16, effectively doubling the physical transmission rates.

5. Automatic Frequency Coordination (AFC)

AFC is a spectrum utilization coordination system used by Wi-Fi 7 when operating in the 6 GHz frequency band. It aims to reduce interference with other services, ensuring normal wireless service.

Comparison between Wi-Fi 7 and Wi-Fi 6:

Wi-Fi 7 Applications and Deployment:

Wi-Fi 7 is still in the development phase, expected to be formally standardized by 2024, but market adoption might occur before then. Some companies like TP-Link and Netgear have introduced compatible devices, but widespread adoption will take some time.

Should You Upgrade to Wi-Fi 7:

Wi-Fi 6 won't quickly become obsolete, but for users facing issues like network congestion or buffering, Wi-Fi 7 promises substantial improvements. Especially in high-density environments like public spaces and large events, Wi-Fi 7's advantages will be more pronounced.

In summary, Wi-Fi 7 offers faster speeds, increased capacity, and lower latency, catering to scenarios requiring high-performance networks such as online gaming and virtual reality. Even if your network speed doesn't reach gigabit levels, Wi-Fi 7's performance enhancements can improve local device communications, supporting seamless connections for devices like VR headsets.
