In the telecommunications sector, AI is transitioning from proof-of-concept and localized pilots into the critical phase of large-scale commercial deployment; however, while leading global operators continue to ramp up AI investment, they have yet to realize commercial value commensurate with that investment. Successfully implementing large-scale AI deployment and translating AI investment into tangible business value has become a pressing challenge for the global telecommunications industry. The *DT4DI White Paper 4.0* notes that without a profound understanding of network structures, underlying mechanisms, and operational states, large models struggle to gain trust in critical production processes. To address this industry bottleneck, the white paper outlines three AI application approaches identified by the industry, identifying the third approach as the inevitable choice for handling complex tasks such as achieving AN L4+ (Autonomous Network Level 4 or higher) capabilities: Approach 1: "Large Language Model (LLM) + Retrieval-Augmented Generation (RAG)." This is limited to retrieving static information and generating text-based explanations; it cannot generate executable optimization commands to form a closed-loop business process, serving primarily as an information query tool.   Approach 2: "Large Language Model + Tool Use." While this represents a technical architectural upgrade, underlying execution still relies on legacy tools; its primary function is to optimize operational workflows and enhance human efficiency.   Approach 3: "Large Language Model + Digital Twin Network (DTN) + Telecom Domain-Specific Large Model." This approach aligns closely with architectural standards for advanced autonomous networks. Unlike LLMs, which focus primarily on interaction, DTNs and telecom domain-specific large models can determine the "Next Best Action" for optimization within the domain. Taking the SRCON 2.0 (Communication Network Reality Simulation 2.0) domain-specific large model as an example, this model reshapes the network optimization paradigm by leveraging comprehensive data collection and processing from intelligent wireless network elements, alongside domain-specific sub-models based on the Transformer architecture—specifically, the User Experience Diagnosis Large Model (UELM) and the Beam-Space Twin Large Model (BSLM). The UELM analyzes comprehensive wireless network data to autonomously identify experience issues and diagnose root causes within the wireless network, while the BSLM automatically simulates and generates global optimization schemes, deploying them to the network to achieve immediate closed-loop resolution. Thus, Digital Twin Networks and telecom domain-specific large models serve as the core engines of a trustworthy AI foundation.

Our company has completed the assembly of a lightweight 10-meter "Cell on Wheels" (COW) unit destined for Iraq. During equipment testing, the generator set and the equipment compartment—equipped with a temperature control module—were powered up simultaneously. All functions operated normally; additionally, the hydraulic system and the winch lifting system were tested and demonstrated smooth, uniform operation. In terms of airframe protection, a collision-cushioning module has also been added.  

Today, we completed the trial assembly of a three-legged tubular steel tower—manufactured for a Jamaican client—prior to the hot-dip galvanizing process to check for dimensional deviations. As each of the tower's three support legs features an independent three-pipe structure, dimensional tolerances are extremely strict. Inspections confirmed that all components meet structural dimension and safety requirements; the tower is now ready to be disassembled for hot-dip galvanizing.   

The shipment of foundation components, seamless steel pipes, and grounding equipment for a camouflage tree tower ordered by a client in Mauritius has been completed. Anchor bolts and positioning templates were dispatched in advance to allow the client to begin foundation construction early. In accordance with the client's specifications, the seamless steel pipes were not galvanized. The copper grounding equipment is intended for the maintenance and replacement of the client's existing local communication towers.

Our team has successfully completed the trial assembly of a 20-meter integrated communication shelter for a client in Morocco. The shelter's hydraulic lifting system has been rigorously tested and verified. Concurrently, all shelter modules have been fully assembled and are now equipped with batteries and power adapters, while the air conditioning system has been seamlessly integrated into the door panels. Once all components are verified to meet strict quality inspection requirements, they will undergo the following surface finishing processes in sequence: Hot-dip galvanizing – strictly in accordance with ASTM A123 / A123M (Standard Specification for Zinc Coatings on Iron and Steel Products). Powder coating – surface preparation and application following ASTM D7803 (Standard Practice for Preparation of Zinc-Coated and Galvanized Steel Surfaces for Powder Coating). Liquid painting – adhering to ASTM D6386 (Standard Practice for Preparation of Zinc-Coated and Galvanized Steel Surfaces for Painting). All three coating processes are executed in full compliance with the respective ASTM standards to ensure maximum corrosion resistance, coating adhesion, and long-term durability for the communication shelter in harsh environments.  

The custom-built 30-meter Cellular on Wheels (COW) unit, commissioned by our client in Zimbabwe, has been fully packaged and loaded into containers, ready for shipment to its destination. The assembly comprises the vehicle chassis, a telescopic tower mast, protective fencing, and an equipment shelter designed for housing communication modules. All exterior components have been safeguarded using protective foam padding; furthermore, within the shipping containers, the cargo has been securely anchored using ropes, fasteners, and wire ties to ensure absolute stability and prevent any shifting during transit.  

The 25m Cellular-on-Wheels unit, destined for Zimbabwe, has successfully completed its trial assembly and operational testing. Timed trials demonstrate that the entire deployment process—from arrival at the site to full operational readiness—can be completed within three minutes.  The chassis platform is equipped with a diesel generator and a power distribution box, enabling the power supply system to be entirely self-sufficient. The distribution box serves as the mounting point for air conditioning units, communication modules, and external circuitry, ultimately providing power to a small office located outside the base station.  

The accompanying image depicts a 15-meter Integrated Communication Shelter and a Power Generator Cabin being crated for shipment to Qatar. The Telecom Cabinet integrates power supplies, adapters, hydraulic systems, and antenna mounting poles; by consolidating all communication support equipment into a single unit, it significantly conserves space while ensuring ease of transport. The Power Generator Cabin is designed to house a generator, utilized for charging or powering mobile communication equipment. It features a fully sealed design that provides dust protection when the unit is idle; conversely, when the generator is in operation, the roller shutter door can be opened to facilitate heat dissipation.

Recently, the integrated communication shelter exported by our company to the United States was successfully deployed and is scheduled to be showcased at an upcoming exhibition in Las Vegas. Also referred to as an "integrated telecom cabinet," this shelter model features a maximum height of 20 meters, supports a maximum antenna load of 500 kilograms, and is rated to withstand wind speeds of up to 200 km/h. According to client feedback, the unit has already been equipped with 5G antennas and Starlink receiving equipment, and is currently operating normally.  

The MW remote-controlled tracking platform, integrated into the top of the Integrated Communication Cabinet, has been successfully developed and is now fully operational. As microwave applications necessitate both signal search and directional transmission capabilities, we adapted a satellite tracking mount to facilitate these functions through horizontal rotation and pitch angle adjustments, thereby ensuring the reliable operation of the microwave system. This equipment model is suitable for Integrated Communication Shelters measuring 20 meters or less.  

With the arrival of the spring plowing season, our company undertook a government contract to design and manufacture a radar support tower, which has now been operating smoothly for one month.
