I. Solution

To address the various challenges of construction in uninhabited areas, construction units have devised multiple strategies. In recent years, with the continuous development of the power market globally, tackling the communication blackout at construction sites has become a priority. To ensure seamless information flow and data collection between field crews and the command center, a practical solution was implemented: deploying multi-integration base stations along the mountainous route. These stations form a high-speed 5.3G/5.8G dual-frequency backbone link, enabling real-time, remote site inspection anytime, anywhere. The multi-integration base stations extend the network to self-organizing mesh network nodes, providing on-site video, voice, and Wi-Fi internet access for mobile phones and computers. This system allows the command center to be immediately informed of any emerging on-site incidents.

Advantages of Wireless Self-Organizing Networks: Portable and Flexible: Easily deployable and removable. Rapidly Relocatable: Capable of establishing a communication network in a short time. Functions of Multi-Integration Base Stations and Self-Organizing Network Base Stations: Production Dispatch: Supports voice calls, fax, and operational coordination. Network Integration and Data Transmission: Access to the internal network of PetroChina. Data transmission, interconnection of computer LANs, and Internet access. Remote Video Surveillance: Enables real-time video monitoring. Emergency Communication Platform Integration: Can be connected to emergency communication platforms. Emergency Communication Platform Access: Provides direct access to emergency response systems.

Multi-Network Convergence Base Station

►Dual-Band High-Speed MESH Bridging: Supports 5.3GHz + 5.8GHz dual-frequency operation for high-capacity wireless backhaul.

►Self-Organizing Network (SON) Base Station: Supports operation in the 1.4GHz frequency band for resilient, ad-hoc network formation.

►Public Network Access: Supports 4G/5G cellular network connectivity for wide-area backhaul and internet access.

ME2600AC is a high-performance tri-band MESH wireless bridge based on the Qualcomm 11AC Wave 2.0 platform. It integrates two independent high-power 802.11ac Wave 2.0 5G modules and one 2.4G Wi-Fi module, which operate without mutual interference. The device supports simultaneous tri‑band operation, where 5G_L and 5G_H can be used concurrently as a dual‑link MESH backhaul, while the 2.4G band operates independently for client coverage. It is suitable for a wide range of applications requiring high‑speed bridging, multi‑hop relay, high‑capacity access, and fast roaming in various project scenarios.

III. Solution Advantages

►Seamless Handover at the Protocol Level

Supports hierarchical grouping and roaming network architecture, extending the system's communication capabilities.

►Link-Independent Operation

The system requires no central network core and can be flexibly deployed as needed. It operates without reliance on traditional infrastructure such as equipment rooms or transmission networks, and can be freely configured. Coverage can be further extended through multi-hop relay networks.

►Multi-Link Data Diversity and Fault

Tolerance Equipped with frequency hopping to effectively improve anti‑interference and anti‑tracking capabilities. Digital filtering is introduced to effectively suppress remote interference. Simultaneously, an ARQ transmission mechanism is adopted, reducing data transmission loss and improving reliability.

►Strong Multipath Resistance

Utilizes COFDM technology, offering strong resistance to multipath effects. The system supports transparent transmission of various service data without requiring differential transparent transmission. Through wideband transmission, it can support clear voice, broadband data, high‑definition video, and other multimedia services.
