Wi-Fi 7: Revolutionizing Next-Generation Wireless Communication - A Journey Towards Enhanced Speed and Reliability

Wi-Fi 7 is ushering in a new revolution in wireless communication technology. Also known as the IEEE 802.11be Extremely High Throughput (EHT) standard, Wi-Fi 7 surpasses existing Wi-Fi 6 and 6E standards, representing a significant leap forward in next-generation wireless communication technology across various aspects such as data transmission speed, stability, and energy efficiency.

The most prominent feature of Wi-Fi 7 is undoubtedly its ultra-high-speed data transmission capabilities. With the supported bandwidth doubled from the previous 160MHz to 320MHz and modulation efficiency improved from 1024QAM to 4096QAM, theoretically, ultra-high-speed transmission of up to 46Gbps is now possible. This represents a speed increase of approximately 4.8 times compared to the maximum 9.6Gbps of Wi-Fi 6 and a staggering 13 times faster than Wi-Fi 5. It's now possible to stream large 8K videos in real-time or download massive 15GB files in about 25 seconds.

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

Moreover, in addition to existing bands, the newly authorized 6GHz band can also be utilized, minimizing interference in congested frequency environments. Wi-Fi 7 also introduces Multi-RU technology for more efficient frequency resource allocation. This eliminates waste in the limited frequency resources, maximizing transmission efficiency.

With 16-stream MIMO technology enabling simultaneous transmission from multiple devices, it can now reliably support over four times the number of devices compared to Wi-Fi 6 in connected home environments. This provides the infrastructure to meet the growing demand for devices in the Internet of Things (IoT).

Wi-Fi 7 also employs Preamble Puncturing technology, making it possible to utilize previously unusable overlapping frequency bands. This maximizes the acquisition of effective frequencies, increases the pure transmission bandwidth, and ultimately maximizes transmission efficiency.

Beyond that, Wi-Fi 7 continues to shine as a next-generation wireless communication technology with enhanced security protocols like WPA3 support and improved power efficiency. It is expected to find applications in various environments, including virtual/augmented reality, 4K/8K streaming, cloud gaming, and remote healthcare.

The incredible evolution of Wi-Fi 7, which anticipates the future, is poised to overcome the limitations we've experienced in wireless communication. This is why so much attention is focused on the Wi-Fi 7 standard technology specifications, which are set to be finalized in 2024. We must keep an eye on Wi-Fi 7, which is set to usher in a new era of wireless communication technology.
