Over the past year, powered by Snapdragon 888, Wi-Fi 6 has become the key to many phone and routing choices, with theoretical speeds of up to 10Gbps, making it a fast alternative to wired networks. There will also be faster Wi-Fi 7 networks in 2023, and network chips will be upgraded to 6nm.
At the same time, the performance of the network chip is also the key. The more high-end network, the network chip also needs more advanced technology. Before, the mature technology such as 28nm was mainly used, but because 28nm is also an important process of vehicle-mounted electronic chip, the network chip faces the problem of production competition. So network chip manufacturers now advance the layout of 6nm and other advanced technology.
TSMC also has a 6nm RF process optimized for RF chips in its 6nm process. Products such as Wi-Fi 7 are expected to be used first, which not only provides higher throughput, but also reduces heat from advanced processes.
Wi-fi 7 has a theoretical peak speed of up to 46Gbps, but considering transmission and interference,The final realistic peak speed is expected to be about 40Gbps after commercial use.
However, even this means that you can download a 4K Blu-ray disc in seconds, so it's no wonder that Mediatek says Wi-Fi 7 is the first time that it really means wireless replacing the wired network.
Wi-fi 7 introduces a number of new technologies, such as 320MHz bandwidth and 4K QAM modulation, but the most anticipated is MLO (Multi-link operation), which will have significant implications for iot devices and is expected to be launched in 2023 and become available in early 2024.
