The following pictures show the 35-meter monopole telecommunication tower being packed and shipped. The tower body is wrapped with cloth to protect it from damage during transportation. Climbing belts are also used in the container to fix the tower body to prevent shaking and ensure the safety of customers' unloading. The part where the bottom of the single-tube tower contacts the container is also padded with wood to prevent damage caused by friction during transportation.  

This week, the National Telecommunications and Information Administration (NTIA) released the results of a two-year "Open RAN" test, showing that although Open RAN technology has passed the early stage, it will take time to reach the same maturity as traditional single-vendor solutions.   NTIA is an agency of the US Department of Commerce, part of its responsibility is to provide telecommunications policy advice to the president.   The program was announced during the Biden administration in 2022 and aims to "accelerate the adoption of open interfaces, interoperable components and multi-vendor solutions to promote the development of an open 5G ecosystem." Competition activities.   Radisys, Capgemini, Mavenir and Fujitsu are said to have participated in the 2022 challenge. Mavenir, NewEdge, Radisys, Fujitsu and GXC participated in the 2023 event. Technological breakthroughs and the gap between reality   NTIA's test report (report link at the end of the article) outlines the current status of open RAN with a set of data:   Four of the vendors have successfully achieved cross-vendor equipment networking - completing the interconnection of O-CU, O-DU and O-RU from different vendors through the Xn interface, and realizing call switching on the N2/Xn interface.   This shows that the open RAN interface technology has made substantial breakthroughs, but the report also points out that compared with the single-vendor solution, there is still a significant gap in the software maturity of open RAN, especially in the upgrade of AI/ML algorithms required for network optimization.   A total of nearly 20 entities' products participated in the test, and NTIA did not disclose the list of companies that passed the test. This practice of "only giving results but not lists" has caused speculation in the industry about the integrity of the test. Industrial competition under policy pushers   Behind this technological competition is the deep projection of the Sino-US technological competition. The "Open RAN Plan" launched during the Trump administration is essentially a strategic extension of the "de-Sinicization" of communication networks.   NTIA under the US Department of Commerce supports local companies through a $1.5 billion funding plan, and the Department of Defense has included open RAN in the military procurement list.   However, the reality is contrary to expectations:   Mavenir and Parallel Wireless, American manufacturers trying to replace Huawei and ZTE, are in financial difficulties; AT&T, which claims to fully embrace open RAN, still relies heavily on Ericsson equipment for its network.   The most ironic thing is that Dish Network, which is regarded as a benchmark for "de-Sinicization", has an open RAN network consisting of 24,000 base stations, and the core equipment mainly comes from Samsung - this Korean manufacturer is neither a traditional equipment manufacturer nor a local American com...

The evaluation experts reviewed the technical data and, after questioning and discussion, believed that the project team had systematically carried out theoretical numerical simulation, experimental and applied research on the anti-collision performance of engineering structures under multi-hazard coupling, and achieved the following major innovative results:   1. The stress and damage mechanism of various types of structural components such as steel columns, steel-concrete composite columns, and highway steel guardrails under impact was revealed, and a full-process analysis method for the dynamic response of structural components and a calculation method for anti-impact bearing capacity based on the dynamic amplification coefficient were proposed, and the basic theory of anti-impact of engineering structural components was developed.   2. A method for evaluating the damage of structural components after impact was proposed, and a method for evaluating the residual bearing capacity after impact considering the coupling effects of load, material, and geometric parameters was established, realizing the quantitative evaluation of damage during the entire impact process and performance-based design.   3. Developed a multi-hazard coupling impact test system, achieved stable load application during impact and accurate capture and control of the hammer after impact, developed a large open-and-close tubular furnace that meets the IS0834 standard heating curve requirements and matches the impact system, and solved the "fire-impact" multi-hazard cooperation test problem.   The project has been granted 14 national invention patents and 1 computer software copyright, and its research results have been included in 4 industry standards. 64 academic papers have been published (24 of which are included in SCI and 32 in EI). The results have been applied to the anti-collision evaluation of more than 20 projects such as Shanxi Xiaohe International Conference Center, Dalian Sports Cente...

C114 News Beijing time May 8 (Ace) According to foreign media reports, recently, 12 major European telecom operators jointly called on regulators to allocate the entire upper half of the 6GHz band (C114 Note: Data shows that this mainly involves 6.425-7.125GHz) to mobile communication services, saying that this move is crucial to ensure that Europe does not lag behind the United States in 6G technology research and development and commercial deployment.   These operators include companies such as Vodafone Group of the United Kingdom, Deutsche Telekom, Telefonica, Telecom Italia and Orange of France. Their chief technology officers jointly signed an open letter and said that they will continue to invest in the construction of European communication networks, but urged a strategic allocation plan for the upper half of the 6GHz band.   The United States opened the band for Wi-Fi in 2020, and China allocated the band for 5G/6G two years ago. Europe has not yet made a final decision on the allocation of the band. Most European countries have previously auctioned spectrum resources in the 3.4GHz to 3.8GHz band for the initial deployment of 5G networks.   The open letter pointed out that the current demand for spectrum resources is growing, and future services including 6G are coming soon. "It is urgent to allocate the entire upper half of the 6GHz band to mobile networks." The letter wrote, "It is expected that by 2030, the mobile communications sector alone will contribute 8.4% of global GDP. If the spectrum resources in the upper half of the 6GHz band cannot be used, the role of mobile communications in promoting GDP growth will be greatly limited." Regarding the development prospects of 6G, operators warned that insufficient spectrum resources will lead to "severe limitations on the service capabilities of this band, and ultimately jeopardize Europe's opportunity to play a leading role in 6G deployment." The letter specifically mentioned that they are worried that American stakeholders are still trying to use this band for Wi-Fi, but emphasized that telecom operators are the main providers of Wi-Fi services for local consumers and enterprises in Europe. If European operators continue to delay their decision to obtain spectrum in this band, and relevant American technology companies are allowed to obtain more 6GHz spectrum resources, then "Europe's competitiveness will face a major threat."
