In detail, for those interested!

Versatility and effectiveness of channels

Wi-Fi 6 uses a technology called Orthogonal Frequency Division Multiple Access (OFDMA) which allows to divide each channel into smaller sub-channels, called tones. Each tone can be assigned to a specific device, allowing for a more efficient use of channels and reducing data collisions. This versatility and efficiency of Wi-Fi 6 channels enable better network traffic management, thereby increasing the speed and reliability of wireless connections.

Increase in bandwidth

Wi-Fi 6 offers a significant increase in bandwidth compared to previous standards. This improvement is made possible by the use of wider channels in the 5 GHz frequency band, increasing from 80 MHz to 160 MHz. By allowing Wi-Fi 6 routers to transmit larger amounts of data simultaneously, this technology provides a dramatic increase in data transmission speed. Furthermore, Wi-Fi 6 uses a more advanced modulation technology, called 1024-QAM modulation, compared to the 256-QAM modulation of Wi-Fi 5. This new modulation allows for denser data transmission, resulting in a significant improvement in data throughput. By combining wider channels and better modulation, Wi-Fi 6 is able to meet the growing bandwidth needs of modern applications, such as 4K video streaming, virtual reality, and online gaming, providing users with a smoother and faster experience.

Better management of connected devices

Wi-Fi 6 standard allows for better management of connected devices by introducing a technology called "OFDMA" (Orthogonal Frequency Division Multiple Access). This technology divides Wi-Fi channels into smaller sub-channels, allowing a Wi-Fi 6 router to communicate with multiple devices at the same time. In other words, a Wi-Fi 6 router can more efficiently manage traffic from multiple connected devices simultaneously, reducing wait times and improving overall network speed. Furthermore, the Wi-Fi 6 standard also utilizes "MU-MIMO" (Multi-User Multiple Input Multiple Output) technology, which enables a router to communicate with multiple devices at the same time, further contributing to better management of connected devices on the network.

Improvement of energy efficiency

Wi-Fi 6 standard promises a significant improvement in energy efficiency compared to previous generations. This improvement is largely due to the OFDMA (Orthogonal Frequency Division Multiple Access) technology, which reduces energy consumption by fragmenting signals into smaller sub-carriers. Thanks to this fragmentation, devices can be turned on and off more quickly, resulting in more efficient energy consumption.

The use of MU-MIMO (Multi-User Multiple Input Multiple Output) technology in Wi-Fi 6 also contributes to energy efficiency by allowing a router to communicate with multiple devices at the same time. This reduces wait times and improves the use of wireless resources, leading to overall energy savings.

Additionally, the Wi-Fi 6 standard includes more advanced sleep features, such as Target Wake Time (TWT), which allows devices to synchronize their wake and sleep periods. This reduces energy consumption by minimizing the time devices need to remain active to communicate with the router.

In summary, the energy efficiency improvement offered by Wi-Fi 6 is based on technologies such as OFDMA, MU-MIMO, and TWT, which enable more efficient energy use and help reduce the ecological footprint of wireless networks.
