6GHz频段争夺战风云突变

Core Viewpoint - The competition for the 6GHz frequency band has intensified, with the FCC's recent decision to auction off parts of this band marking a significant shift in the global telecommunications landscape [1][11][12]. Group 1: Importance of 6GHz Frequency Band - The 6GHz frequency band is a critical resource due to its combination of wide coverage and high capacity, making it a strategic asset for both mobile communication and WiFi technologies [1][5][6]. - The 6GHz band is seen as essential for the development of future mobile communication systems, particularly 6G, over the next 5 to 10 years [7][13]. Group 2: Global Positioning and Strategies - China has already taken a clear stance by allocating the upper part of the 6GHz band (6425—7125MHz) for IMT systems in 2023, positioning itself as a leader in the global telecommunications race [1][15]. - The U.S. initially opposed this allocation, having designated the entire 6GHz band for WiFi use in 2020, but has now reversed its position to allow for IMT system usage through an auction process [1][11][12]. Group 3: Industry Dynamics - The mobile communication camp, including major operators and equipment manufacturers, has united to advocate for the use of the 6GHz band for mobile systems, highlighting its importance for future developments [7][13]. - Conversely, the WiFi camp is pushing for access to the 6GHz band to alleviate congestion issues faced by existing 2.4GHz and 5GHz bands, which are becoming increasingly inadequate for modern applications [7][8]. Group 4: Regional Developments - India has also announced its allocation plan for the 6GHz band, designating the upper part for 6G systems and the lower part for WiFi, reflecting a trend towards a balanced approach in frequency allocation [10][14]. - The FCC's recent decision aligns with a growing consensus among global telecommunications operators, including those in Europe, advocating for the upper part of the 6GHz band to be reserved for mobile networks to maintain competitive advantage [13][14].
