Wi-Fi 7 is heralding a new revolution in wireless communication technology. Also known as the IEEE 802.11be Extremely High Throughput (EHT) standard, Wi-Fi 7 surpasses the existing Wi-Fi 6 and 6E standards, achieving a quantum leap in data transmission speed, stability, energy efficiency, and other aspects, making it a next-generation wireless communication technology.

The most notable feature of Wi-Fi 7 is undoubtedly its ultra-high data transmission speed. The supported bandwidth has doubled from the previous 160MHz to 320MHz, and the modulation efficiency has also been enhanced from 1024QAM to 4096QAM, theoretically enabling ultra-high speed transmission of up to 46Gbps. This is about 4.8 times faster than the maximum 9.6Gbps of Wi-Fi 6 and a staggering 13 times faster than Wi-Fi 5. You can now stream large 8K videos in real-time or download 15GB files in approximately 25 seconds.

In addition, Wi-Fi 7 employs MLO (Multi-Link Operation) technology, allowing a single device to simultaneously utilize multiple frequency bands, including 2.4GHz, 5GHz, and 6GHz. This enables the diversification of transmission paths and efficient utilization of bandwidth, resulting in significantly improved throughput, reduced latency, and enhanced reliability and efficiency.

Moreover, Wi-Fi 7 can utilize not only existing bands but also the newly authorized 6GHz band, minimizing the impact of interference in crowded frequency environments. Wi-Fi 7 also incorporates Multi-RU technology for more efficient utilization of frequency resources. This allows for the waste-free use of limited frequency resources, maximizing transmission efficiency.

With 16-stream MIMO technology, multiple devices can transmit simultaneously, enabling connected home environments to reliably support more than four times the number of devices compared to Wi-Fi 6. This provides the infrastructure to meet the growing demand for devices in the Internet of Things.

Wi-Fi 7 also incorporates Preamble Puncturing technology, enabling the utilization of previously inaccessible overlapping frequency bands. This maximizes the acquisition of valid frequencies, increasing pure transmission bandwidth and maximizing transmission efficiency.

Furthermore, Wi-Fi 7 enhances its value as a next-generation wireless communication technology by supporting the more advanced security protocol WPA3 and improving power efficiency. It is expected to be utilized in various environments such as virtual/augmented reality, 4K/8K streaming, cloud gaming, and remote healthcare.

Such forward-looking innovations in Wi-Fi 7 are poised to overcome the limitations of wireless communication we have been experiencing. This is the reason why so much attention is focused on the Wi-Fi 7 standard specifications that will be finalized in 2024. We should pay close attention to the advancements of Wi-Fi 7, which will open new horizons in wireless communication technology.
