The launch of WiFi 7 will further improve network speed, capacity and efficiency, bringing users a better network experience. This article will explore the characteristics and advantages of WiFi 7 in depth and take you to understand this technology.

Understanding WiFi 7

WiFi 7, also known as IEEE 802.11be, represents the next generation of wireless networking standards. Building on the foundation laid by WiFi 6 and WiFi 6E, WiFi 7 is designed to offer unprecedented data rates and improved efficiency. While WiFi 6 introduced features like Orthogonal Frequency Division Multiple Access (OFD

MA) and Target Wake Time (TWT) to enhance performance, WiFi 7 takes these innovations further, aiming to deliver Extremely High Throughput (EHT) and improved spectrum utilization. This advancement is crucial as the demand for faster and more reliable internet connections continues to grow, driven by the increasing number of connected devices and bandwidth-intensive applications.

Key Features of WiFi 7

WiFi 7 is characterized by several groundbreaking features that set it apart from its predecessors:

Extremely High Throughput (EHT): WiFi 7 is expected to support data rates up to 30 Gbps, significantly higher than WiFi 6’s maximum of 9.6 Gbps. This boost in speed will enhance the user experience, particularly in data-intensive applications like 8K video streaming and virtual reality. The ability to deliver such high throughput is essential for supporting future technological advancements that demand high-speed data transmission.

Enhanced Multi-Link Operation (MLO): One of the standout features of WiFi 7 is its ability to use multiple links simultaneously. This multi-link operation allows for more stable connections and reduces latency, making it ideal for applications that require real-time responsiveness, such as online gaming and video conferencing. By utilizing multiple frequency bands at once, WiFi 7 can intelligently manage network traffic, ensuring consistent performance even in congested environments.

Wider Channels and Better Spectrum Utilization: WiFi 7 supports wider channels of up to 320 MHz, compared to WiFi 6's 160 MHz. This increased bandwidth allows for more data to be transmitted at once, improving overall network capacity and efficiency. The use of wider channels is particularly beneficial in areas with high device density, where network traffic can easily become congested.

Improved Latency and Connectivity Stability: With advanced features like MLO and wider channels, WiFi 7 significantly reduces latency, ensuring that devices remain connected without interruptions. This improvement is crucial for emerging technologies that require stable and fast connections, such as autonomous vehicles and remote-controlled machinery.
