Wi-Fi 6 will be popular this year Wi-Fi 7 will be available next year: the rate can reach 40Gbps

Wi-Fi wireless network is already an indispensable part of home travel, after this two years of efforts, Wi-Fi 6 has penetrated into cell phones, routers and notebooks and other devices, this year's Wi-Fi 6 shipments are up to 2.3 billion, PC penetration rate of more than 50%, next year will see the launch of Wi-Fi 7. The theoretical rate of Wi-Fi 6 can reach 10Gbps, and many cell phones and routers can achieve the actual rate of 2Gbps, which is faster than wired bandwidth and has very low latency. According to the Wi-Fi Alliance, the number of Wi-Fi 6 devices shipped is expected to reach 2.3 billion in 2022, and the number of enhanced Wi-Fi 6E devices will be 350 million. After the maturity of Wi-Fi 6/6E, MediaTek, Qualcomm, Rene, and other manufacturers are also actively preparing for the next generation of Wi-Fi 7 technology, three manufacturers of Wi-Fi 7 chips have been successfully developed, of which Qualcomm, MediaTek faster progress, this year on production, Rene's Wi-Fi 7 chip to the second half of 2023. According to the introduction, Wi-Fi 7 will support 2.4GHz, 5GHz, 6GHz three bands, and through 320MHz channel, 4K QAM orthogonal amplitude modulation technology, in the conditions of using the same number of antennas, the transmission speed than Wi-Fi 6 as much as 2.4 times faster, theoretical peak network speed of 46Gbps, but taking into account the transmission, interference and other circumstances, it is expected that after the commercial However, taking into account transmission and interference conditions, the realistic peak speed is expected to be around 40Gbps after commercialization. However, Wi-Fi 7 devices will not be available until at least 2023, and the complete specification and product maturity will not be available until 2024.
