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...

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."

The following pictures show the monopole antenna pole packing site and packaging reference. The antenna pole is packed with flannel cloth and stainless steel rolled tape.   Also packed are the artificial palm leaves of the bionic palm tree tower. Palm leaves are packed in cartons for protection, 50 leaves per box. Every two branches are packed into a bundle, which is convenient for customers to unload.   

The following pictures show the trial assembly of the leaves of the  palm tree monopole tower and some technical parameters. The branches are made of fiberglass and do not contain steel bars. The leaves are made of PE material and have no impact on the frequency band of mobile communication signals. And the length of the foliage can be OEM from 3m to 4.5m as per the client's demand.    

The following pictures show the packaging of the three-legged angle steel communication tower. They are all suitable packaging methods for sea transportation, and bumps are avoided as much as possible during the packaging process.    

The following pictures show the packaging site of the 45 Meters 3-Legged Angle Steel Telecom Tower before delivery. We use flannel to pack the angle steel parts at the beginning and end, and fix them with stainless steel binding tape. The remaining parts are connected in sequence with iron wire to prevent omission and confusion.    

The following pictures show the zinc layer thickness test of the three-leg angle steel tower after galvanizing. We will strictly inspect and test each batch of galvanized products according to ASTM A123 standards to ensure that the zinc layer thickness meets the quality requirements.、 Reference Standards： ASTM A123/A123M: Specifies requirements for galvanized coatings on steel products. Key parameters include: Minimum Average Thickness: Varies with steel thickness: ≥6.35 mm (1/4 inch): 100 µm (3.9 mils) average, 85 µm (3.4 mils) minimum local. <6.35 mm: 50 µm (2.0 mils) average, 45 µm (1.7 mils) minimum local. Sampling: Test 3 articles per lot, with 3 measurements per article (9 total).  

The following pictures are on-site photos of packaging and shipping, in total 7 sets of monopole tower loaded in 3 containers. Each tower body is wrapped with foam cotton to prevent scratches during shipping and transportation.  

As shown in pictures is the trial assembly site of 45m 3 legged angle steel tower for our Samoan client. Trial assembly before hot-dip galvanization helps ensure that all components of the angle steel tower fit together correctly and align properly before galvanization. It allows for the identification of any discrepancies or issues in the assembly process that can be addressed and corrected before the final galvanization step.  Ensuring proper fit and alignment through trial assembly before galvanization can contribute to the long-term durability and performance of the angle steel tower, reducing the risk of premature corrosion or structural issues.
