Wi-Fi 7, officially known as 802.11be, is set to revolutionize wireless connectivity by significantly enhancing speed, efficiency, and reliability. One of its most impressive advancements is supporting channels up to 320 MHz wide, effectively doubling the bandwidth possibilities of Wi-Fi 6E. This expansion enables much higher data throughput, especially in the less congested 6GHz band.
A key feature of Wi-Fi 7 is the introduction of Multi-Link Operation (MLO). MLO allows for simultaneous connections across various frequency bands and channels, such as 2.4 GHz, 5 GHz, and 6 GHz. By intelligently distributing traffic, Wi-Fi 7 offers smoother connections in dense environments where interference is typical.
In terms of theoretical maximum throughput, Wi-Fi 7 significantly surpasses its predecessors, reaching speeds of approximately 46 Gbps, which is nearly five times greater than Wi-Fi 6’s maximum of 9.6 Gbps. This substantial increase in throughput will support future data-intensive tasks, higher device densities, and improved connectivity for real-time applications.
Wi-Fi 7 does not exclusively operate on the 2.4 GHz frequency band. Instead, it continues the multi-band approach of previous standards by utilizing 2.4 GHz, 5 GHz, and the recently introduced 6 GHz bands from Wi-Fi 6E. The 2.4 GHz band is crucial for long-range connectivity and compatibility with legacy devices, while the 5 GHz and 6 GHz bands offer higher throughput and lower latency due to reduced congestion and interference.
Beamforming technology and advanced modulation schemes, such as 4096-QAM (Quadrature Amplitude Modulation), further boost Wi-Fi 7’s efficiency and performance. The higher modulation rate allows more data to be transmitted with each signal, enhancing speeds and network responsiveness.
