特朗普的“大而美法案”要给Wi-Fi 7降速？

Core Viewpoint - The battle for the 6GHz spectrum is intensifying globally, with the Wi-Fi camp celebrating a victory in India for unlicensed use of the lower band (5925—6425MHz), while facing uncertainty in the U.S. due to Trump's recently signed "Big and Beautiful Act" which complicates the ownership of the 6GHz spectrum [1][7][21]. Group 1: Legislative Changes and Implications - Trump's "Big and Beautiful Act" includes provisions for spectrum auctions as a means to support large-scale tax cuts, restoring the FCC's auction authority and requiring the release of at least 800MHz of spectrum within eight years [3][5]. - The mobile communication industry currently holds only about 5% of the commercial spectrum in the 3GHz—8.4GHz range, while 60% is controlled by the federal government, including military use [3][5]. - The Senate's revision of the bill expanded the spectrum available for auction, removing the exclusion of the 5.925–7.125 GHz band, which poses a risk to the previously allocated 6GHz spectrum for Wi-Fi [7][10]. Group 2: Industry Reactions and Economic Impact - The Wi-Fi Alliance expressed gratitude for the initial exclusion of the 6GHz band from auction, emphasizing its importance for the future development of Wi-Fi technology [6]. - The Wi-Fi industry had anticipated benefiting from the release of more spectrum but now faces the potential loss of the 6GHz band, which could impact the deployment of Wi-Fi 7 networks [8][16]. - Major tech companies and industry organizations, including Apple and Meta, have urged senators to support the unlicensed use of the 6GHz band, highlighting its projected economic value of approximately $2.4 trillion by 2027 [12]. Group 3: Political Dynamics and Future Outlook - Senator Ted Cruz, a strong proponent of spectrum auctions, argues that expanding the auction range will increase federal revenue and enhance U.S. competitiveness in 5G/6G networks [10][11]. - The ongoing conflict between the Wi-Fi Alliance and the CTIA reflects deeper industry divisions, with the CTIA advocating for the allocation of the 6GHz band to mobile operators to address competitive disadvantages [16][21]. - The "Big and Beautiful Act" has created a policy battleground over the 6GHz spectrum, which may influence global markets, particularly in Europe, where similar spectrum battles are ongoing [20][22].
