Core Viewpoint - The article discusses the ongoing debate in Europe regarding the allocation of the 6 GHz frequency band, with mobile network operators advocating for its exclusive use for 5G and 6G services, while the Wi-Fi Alliance and Dynamic Spectrum Alliance (DSA) argue for its continued availability for Wi-Fi applications, highlighting the potential impact on digital development in Europe [1][2]. Group 1: Stakeholder Positions - The Wi-Fi Alliance and DSA express concerns that restricting Wi-Fi access to the 6 GHz band would severely hinder digital development in Europe, emphasizing that Wi-Fi is a primary means for consumers to access the internet [2]. - A spokesperson from Germany's Federal Ministry of Digital and Transport indicates that the demand for the 6 GHz band from mobile network operators is considered higher than that for Wi-Fi applications, suggesting a shift in policy [2][3]. - The DSA claims that blocking Wi-Fi access to the 6 GHz band would have a devastating impact on the future of Wi-Fi technology in Europe, which is crucial for maintaining the Wi-Fi ecosystem and fostering digital innovation [2]. Group 2: Technical and Regulatory Context - Reports indicate that the spectrum available for Wi-Fi is significantly less than that for mobile networks, with demand for the 6 GHz band from Wi-Fi expected to exceed that of mobile networks [3]. - Vodafone has previously tested the 6 GHz band, achieving download speeds of up to 5 Gbps, and argues for opening the band to enhance cellular network capacity as existing bandwidth becomes exhausted [3][4]. - The International Telecommunication Union (ITU) has supported the mobile communications sector by designating the 6 GHz band for cellular services at the 2023 World Radiocommunication Conference [4]. - The European Commission plans to make a technical coordination decision regarding the 6 GHz band, with a report from the European Conference of Postal and Telecommunications Administrations (CEPT) due by July 2027 [4].
