1.1.1 Base Station Replacement Applications

Main Application: Solving the challenges of site selection for new or relocated base stations.

With the ongoing development of urban economies and the rising cost of housing in cities, the rental cost of mobile communication machine rooms has increased significantly, and coordination has become more difficult. Choosing a machine room has increasingly become one of the most critical issues in network optimization. Additionally, this has resulted in longer cycles for building or relocating machine rooms, which hinders the ability to quickly and efficiently provide high-quality coverage services, directly affecting customer service quality.

The 5G high-power fiber optic repeater station product uses a new outdoor unit design. The compact design is suitable for outdoor environments and does not require dedicated machine rooms, effectively solving the issue of site selection. Moreover, the equipment is easy to install, reducing construction time and quickly resolving network complaints and improving service quality. This solution is a fast and efficient method for network optimization.

• Centralized Machine Room Application

This method targets new or relocated base stations that do not have space for a machine room. By utilizing the fiber optic long-distance extension and equal coverage functionality of high-power fiber optics, the machine rooms can be centralized at one location. Alternatively, spare capacity in surrounding base station machine rooms can be utilized by expanding the cabinet as the fiber optic source. A digital fiber optic system (collecting and splitting high power) is used to achieve equivalent coverage to that of a base station.

1.1.2 Sector Blocking Applications

Main Application: Solving the problem of sector blocking in urban base stations.

As urban areas develop and new high-rise buildings emerge, the original base station layout becomes affected by new obstacles such as buildings, creating shadow zones or areas with weak signal coverage. This leads to more significant network coverage issues. Currently, most solutions involve building or relocating new base stations, which greatly increase operators' investment costs. A 5G high-power repeater station can effectively solve these problems without needing to relocate base stations, optimizing shadow zones or weak areas and improving network quality.

The primary solution is to use the original base station solely for signal source purposes, and replace the coverage area with a high-power fiber optic repeater station. Additionally, a second remote unit with a one-to-two configuration can cover the shadow zones. This makes use of the fiber optic product's delay adjustment functionality, avoiding the challenges of network optimization or the complexity of building or relocating base stations.

The solution is applicable to urban, suburban, and rural areas.：

1.1.3 Residential Area Applications

Current challenges for residential areas include:1.High sensitivity to base stations.2.Difficulty in covering low-rise areas.3.The "ping-pong effect" in high-rise buildings.For these coverage issues, several solutions are recommended:：

• Solution 1: Base Station Coverage

This solution targets low to mid-rise residential areas (6-7 floors, typically without elevators or basements). Particularly, areas with high points inside or outside the complex can use a high-power fiber optic repeater station combined with base station aesthetic antennas to optimize coverage. The sector division can be adjusted based on actual needs.：

• Solution 2: Combined Indoor and Outdoor Coverage

This method is aimed at residential complexes with significant coverage challenges, typically those with basements, elevators, low floors, and high floors. The indoor system uses a distributed solution, while the outdoor system optimizes coverage with either long-distance base station signals or outdoor distributed antennas, using aesthetic antennas for optimization.

• Solution 3: Indoor Distributed Coverage

This is used for mid- to high-rise residential areas, employing indoor distribution systems to solve the coverage issues.

• Solution 4: Outdoor Distributed Coverage

   This solution is designed for low- to mid-rise residential areas, using outdoor aesthetic antennas (e.g., lamp-post or billboard-style) and distributed high-power fiber optic repeater stations installed in decorative cabinets for optimized coverage.

1.1.4 Scenic Area Applications

For scenic areas and other environments with high aesthetic requirements, a centralized high-power fiber optic repeater station combined with aesthetically designed base station antennas provides an optimal solution. The system uses a single or three-sector configuration in a centralized cabinet, with antennas that have been beautified.

1.1.5 Highway Long-Distance Coverage Applications

For coverage of regular highways, expressways, bridges, valleys, rivers, and other elongated areas with low traffic volume, long-distance coverage within the same sector can be used. This ensures even signal coverage and reduces the number of handovers. The high-power fiber optic repeater station can make full use of its delay adjustment and serial-parallel grouping functionality to achieve continuous optimized coverage. Additionally, using the collecting and splitting function can improve the uplink anti-fading characteristics, ensuring the signal quality. The serial-parallel function helps maximize fiber optic resource utilization.：

1.1.6 High-Speed Railway Optimization Applications

With the continuous development of high-speed railways in China, network issues on high-speed railways have become increasingly prominent, including insufficient handover zones and weak coverage strength, which severely affect mobile communication services. The high-power fiber optic repeater station is used to address these issues. By using serial-parallel functionality and delay adjustment, the system overcomes delay problems and reduces noise introduced by excessive cascading devices. This solution effectively solves the issues of too many handover zones, utilizing delay adjustment and serial-parallel networking functionality. It enables long-distance coverage with the same-sector signal and supports network configurations of up to 4 (parallel) * 6 (serial), with low investment costs and short construction cycles.：
