As Sun Tzu said, "Every Battle is won before it is fought" https://lnkd.in/gFqp29ad COP28 wasn't the only recent big deal in Dubai. The International Telecommunication Union World Radio Conference 2023 (WRC-23) https://lnkd.in/g5a-DKYX wrapped, with the US scoring a victory by maintaining protections for #DefenseDepartment #radars from #spectrum #interference (Big for Navy's Aegis)— while at the same time opening up room for expanding spectrum use by #5gtechnology and future #6gtechnology mobile communications networks but limiting China Huawei 5G ambitions. According to US official Steve Lang, State Department deputy assistant secretary for international information and communications policy and lead for the US delegation, told reporters today that WRC-23, which began Nov. 20 in #Dubai, “has been a clear success for US interests.” In particular, Lang said, the US won ITU approval for its plan to “further harmonized spectrum available for 5G across the Americas” by allowing wireless mobile phone networks to use frequencies in the 3.3 to 3.4 gigahertz and the 3.6 to 3.8 gigahertz bands in the region — freeing up some 500 megahertz of spectrum for 5G wireless use while also “ensuring protection for important incumbent systems.” Lang added that the WRC-23 also enacted “steps to ensure protection of radio location systems [radar] that are crucial to national defense and identified new frequencies for aviation and maritime transportation safety systems as well.” Within the US, part of the 3 GHz band is allocated first and foremost to use by radar systems owned by government agencies, particularly DoD. WRC-23 was a significant event for China, #Huawei, and global 5G development. China actively pushed for new mid-band spectrum allocations for 5G, advocating for 1490 MHz total compared to the US proposal of 100 MHz. This move aimed to increase 5G capacity and potentially benefit Chinese vendors like Huawei. While unsuccessful, this attempt underscored China's vision for future network technology. US successfully protected its Pentagon radar spectrum. Despite China's proposals, the US and its allies maintained exclusive use of specific frequencies for military purposes. They limited progress on 6 GHz band harmonization and no consensus was reached on globalizing the 6 GHz band for 5G, leaving the issue unresolved for now. https://lnkd.in/g-vSYy4h WRC-23 did achieve positive outcomes in allocating spectrum for various satellite orbits, which could benefit broader telecommunications infrastructure. However International regulators have left the door open to relaxing a cap on #satellite transmission #power in non-geostationary #LEO and #MEO orbit as soon as 2027, NGSO operators say, even as their geostationary peers assert any change has been blocked until at least four years later.
