A new wireless LAN standard `` Wi-Fi 6E '' with 6 GHz band available is announced
Wi-Fi Alliance, which formulates wireless LAN standards, extends the new standard ' Wi-Fi 6E ' that extends the frequency of wireless radio waves used for communication to the 6 GHz band (5.925 GHz to 7.125 GHz) Announced.

Until now, the Wi-Fi standard supported two frequencies, the 2.4 GHz band and the 5 GHz band, but with the increase in Wi-Fi compatible terminals in recent years, it is expected that available frequency channels will be insufficient. Was. Especially in the 2.4GHz band, it is easy to interfere due to the channel, and there may be situations where satisfactory communication cannot be performed.
Wi-Fi 6E is a standard that adds a 6GHz band to Wi-Fi 6 (IEEE 802.11ax) announced in October 2018 as a frequency that does not require a wireless license. Wi-Fi 6E is suitable for high-resolution video streaming and high-speed data communication. In the 6 GHz band, 14 channels of 80 MHz width and 7 channels of 160 MHz width are prepared. The Wi-Fi Alliance says that communications in the 6GHz band will be available immediately with regulatory approval.
Research firm IDC says Wi-Fi 6E will be used first in consumer access points and smartphones, and later in enterprises for applications such as machine learning analytics, remote maintenance, and employee VR (virtual reality) training applications I expect it to be.
'If regulatory approval is granted and the 6GHz band becomes available, products supporting the 6GHz band will rapidly increase, as IDC research director Phil Solis said. It is enormous and is used efficiently by Wi-Fi 6 and later versions of Wi-Fi.In the United States, the Federal Communications Commission has already released the 6 GHz band to unlicensed frequencies , Europe and the Pacific・ The use of 6GHz is being approved in the Asian region. '
According to the Wi-Fi Alliance, `` Wi-Fi is recognized as a fundamental technology of the Internet of Things (IoT), and it has made a significant contribution to the global economy by enabling the provision of 5G to areas where communication network services are not enough. 'Wi-Fi 6E uses 6GHz to provide highly anticipated VR and AR (Augmented Reality) use cases for the consumer, business and industrial environments.'
