In view of the rapid increase in Wi-Fi applications and the increasing reliance of users on wireless Internet access, the Wi-Fi Alliance expects that by 2020, Wi-Fi data transmission will exceed the current non-authorization. The upper limit of the capacity that spectrum resources can support. To this end, the Wi-Fi Alliance called on the competent authorities to re-examine the video spectrum policy and adjust the current allocation ratio of unlicensed spectrum and licensed spectrum to meet future Wi-Fi transmission requirements.
The Wi-Fi Alliance recently released its commissioned spectrum requirements research report, which is designed to assess whether the currently available spectrum resources can meet the market's need for Wi-Fi technology. The report pointed out that by 2020, the number of Wi-Fi devices in use worldwide will increase from the current 8 billion to 12 billion, and Wi-Fi will be used in applications with larger data transmission traffic. Therefore, the spectrum resources of the 5 GHz band will not be available at that time.
Edgar Figueroa, president and CEO of the Wi-Fi Alliance, said that Wi-Fi technology makes life easier for users, such as using Wi-Fi to connect with others, learn, work, and even manage a range of autonomous smart applications. . Therefore, users are increasingly dependent on Wi-Fi. Due to the increasing demand for Wi-Fi, it is necessary to review the existing spectrum allocation policies to meet the large demand for Wi-Fi.
The report suggests that if Wi-Fi demand grows at its estimated rate, by 2020, Wi-Fi will have to use resources in the 500MHz to 1GHz band to meet user demand; but if Wi-Fi applications grow The speed is faster than the study estimates, and by 2025, the 1.3GHz to 1.8GHz spectrum must be released for Wi-Fi. Moreover, since Wi-Fi will be used in applications with larger data traffic, these new bands must be as continuous as possible to support channel bandwidth of 160 MHz.
Alex Roytblat, senior director of global policy affairs at the Wi-Fi Alliance, said that over the years, the Wi-Fi industry has continued to develop innovative solutions to provide wireless connectivity to billions of users while meeting bandwidth and policy constraints. However, according to the estimates of this research report, the application scale of Wi-Fi has been developed to the point where more unlicensed bands must be used, and these spectrum resources must be released as soon as possible in order to keep up with the growth of Wi-Fi demand.
