Group 1 - The Regulatory Agency for Communications (RAK) in Bosnia and Herzegovina has not established a legal timeline for shutting down 3G networks, nor does it have a clear strategy for introducing 5G networks [1][2] - RAK emphasizes that 3G services can only be terminated once sufficient 4G coverage is ensured, and the current telecommunications policy does not mandate a specific deadline for the closure of 3G services [1][4] - The transition from 3G to 4G is complex, requiring detailed planning from operators, and timely communication to users is crucial to ensure a smooth transition [1][4] Group 2 - The issuance of 5G licenses and the establishment of regulatory rules for 5G are not prioritized in Bosnia, as the focus remains on achieving 4G coverage requirements set for mid-2024 [2][3] - The draft policy for the electronic communications sector (2023-2027) anticipates the possibility of issuing licenses for 5G, but it has not yet been approved [2][3] - Neighboring countries like North Macedonia and Montenegro have made significant progress in 5G coverage, while Bosnia, Serbia, Turkey, and Ukraine are still awaiting the introduction of 5G networks [2] Group 3 - RAK has identified three frequency bands available for new generation network licenses: 700MHz, 3.5GHz, and 26GHz, with a transition period for spectrum migration extending until the end of 2026 [3] - The preparation for licensing requires a detailed analysis to determine appropriate spectrum allocation methods, considering economic and market factors affecting 5G network implementation [3] - The passage of a new Electronic Communications Law is crucial for improving spectrum allocation and 5G deployment, aligning with the European Electronic Communications Code [3] Group 4 - Telecom operator Mtel is gradually shutting down 3G technology and migrating users to 4G, confirming that RAK has not mandated a closure timeline [4] - Mtel's 4G network currently covers 97.76% of the population and 97.30% of the roads in Bosnia, laying a foundation for successful migration from 3G to 4G [4] - The industry faces challenges such as unclear regulatory policies, the need for spectrum resource coordination, and delayed strategic planning, which contribute to uncertainty in the transition to 5G [4]

Core Viewpoint - Colombia aims to strengthen cooperation with China in communication technology to bridge the digital divide in the region [1] Group 1: Key Areas of Cooperation - The Colombian Ministry of Communications, led by Deputy Minister Perdomo, visited China to discuss topics such as digital infrastructure, next-generation networks, spectrum management, satellite capabilities, cybersecurity, and artificial intelligence [1] - The visit is intended to enhance bilateral technical and policy dialogue through experience sharing and practical cooperation [1] - Collaboration with Chinese information and communication research institutions is expected to uncover opportunities in telecom infrastructure, institutional capacity building, and regulatory practices [1] Group 2: Focus on Education and Training - Discussions during the visit included talent development, technical training, academic exchanges, and professional certification [1]

Core Viewpoint - The Chinese delegation successfully completed its tasks at the International Telecommunication Union's Radiocommunication Sector (ITU-R) meetings, contributing significantly to international spectrum management efforts [1] Group 1: Meeting Overview - The meetings took place in Geneva, Switzerland, from June 9 to June 19, focusing on the third session of the SG1 and its working groups in the research cycle for the 2027 World Radiocommunication Conference (WRC-27) [1] - SG1 is responsible for spectrum management, with three working groups dedicated to spectrum engineering technology, management methods and economic strategies, and spectrum monitoring [1] Group 2: Key Discussion Topics - The discussions centered on visible light communication, wireless charging, spectrum availability assessment, and revisions to the spectrum monitoring handbook [1] - The meeting reviewed and approved three recommendations and two report revisions [1] Group 3: Contributions from the Chinese Delegation - The Chinese delegation submitted ten documents addressing the impact of wireless charging on radio communication services, economic issues in spectrum management, and calculations of total radiation power in external fields, all of which were adopted by the meeting [1] - The outcomes of the meeting included multiple contributions to international spectrum management, showcasing China's ongoing commitment to this field [1]
