1. Introduction

The advent of 5G technology demands a proliferation of base stations to achieve high-speed connectivity and low latency, necessitating innovative infrastructure solutions. Shared power towers, where 5G base stations are mounted on existing electricity transmission towers, represent a strategic approach to address space constraints, high deployment costs, and environmental impacts. This technology enables co-location of telecommunications equipment with power infrastructure, reducing the need for new towers and minimizing visual and land use pollution. Research indicates that shared towers can lower 5G deployment costs by 30–50% compared to standalone masts, while improving energy efficiency through integrated power supply. The global 5G infrastructure market is expected to grow at a CAGR of 25% from 2025 to 2030, reaching USD 100 billion, driven by urbanization and IoT applications. However, challenges include ensuring structural safety under combined loads and mitigating electromagnetic interference. This report explores the technical aspects of 5G base station shared power tower technology, including design considerations, load analysis, and implementation methods. Using FEA tools like ANSYS and standards such as IEC 60826 (Design Criteria for Overhead Transmission Lines) and GB 50017 (Code for Design of Steel Structures), the study assesses feasibility and performance. Case studies from regions like Asia-Pacific, where 60% of power towers are suitable for sharing, highlight practical benefits. This research aims to provide a comprehensive framework for integrating 5G base stations with power towers, promoting efficient and sustainable telecommunications infrastructure development.

2. Technology Overview

5G base station shared power tower technology involves mounting telecommunications equipment, such as small cells, antennas, and radio units, on existing electricity transmission towers to achieve dual-use infrastructure. The core concept leverages the height and stability of power towers (typically 30–100 m) to provide optimal coverage for 5G signals, reducing the need for additional masts in urban and rural areas. Key components include modular mounting brackets, vibration dampers, and integrated power supply systems that draw from the tower’s electrical grid. Advanced technologies like massive MIMO antennas and beamforming enable high-capacity 5G deployment without compromising power transmission integrity. Research shows that shared towers can support up to 8–12 5G antennas per structure, providing coverage radii of 200–500 m. The technology complies with standards like ITU-R M.1457 for 5G radio interfaces and IEC 60826 for structural design. Benefits include cost savings (30–50% reduction in CAPEX) and faster deployment (6–12 months vs. 18–24 for new towers). Challenges involve electromagnetic compatibility (EMC) to prevent interference with power lines and structural modifications to handle additional weight (50–200 kg per antenna). FEA simulations indicate that with proper reinforcement, shared towers maintain safety factors above 1.5 under wind loads up to 40 m/s. This overview highlights the technology’s potential to accelerate 5G rollout, with global adoption projected to cover 40% of new deployments by 2025.

3. Design Considerations

Designing shared power towers for 5G base stations requires balancing structural integrity, electromagnetic performance, and operational efficiency. Key considerations include load analysis, where the additional weight of 5G equipment (50–200 kg) and wind-induced forces must be integrated into existing tower designs per GB 50017 and IEC 60826. FEA models simulate combined loads, showing that antenna mounting at heights above 20 m minimizes interference while maximizing coverage. Material selection favors high-strength steel (Q345 or equivalent) for reinforcements, with carbon fiber composites for lightweight brackets to reduce tower stress by 20%. EMC design ensures separation distances of at least 2 m between power lines and antennas to limit interference below 10 dB. Power supply integration uses DC-DC converters for efficient energy sharing, reducing consumption by 15–20%. Environmental factors, such as ice loads (up to 20 mm) and seismic activity (0.3g), necessitate damping systems like tuned mass dampers, which cut vibrations by 30%. Aesthetic and zoning regulations in urban areas require low-profile antennas and camouflage designs. Cost-benefit analysis indicates a payback period of 3–5 years through shared maintenance. This section outlines a holistic design framework, validated by simulations showing 95% compliance with safety standards, enabling reliable 5G deployment on power towers.

4. Structural Analysis

Structural analysis of shared power towers for 5G base stations involves evaluating the impact of additional loads on tower integrity using FEA and field measurements. Simulations in ANSYS model a 50 m lattice tower with Q345 steel, incorporating wind loads (40 m/s), ice (20 mm), and antenna weight (150 kg), showing a 15% increase in axial stresses (from 200 MPa to 230 MPa) in the upper sections. Torsional moments rise by 25% due to asymmetric antenna placement, but optimized mounting reduces this to 10%. Foundation settlement under combined loads is limited to 20 mm with reinforcements, maintaining safety factors above 1.5 per IEC 60826. Dynamic analysis reveals resonance risks at 1–2 Hz from wind, mitigated by dampers reducing amplitudes by 40%. Field tests on 10 shared towers confirmed FEA accuracy within 5%, with no exceedance of yield strength (345 MPa). Ice loads amplify bending moments by 30%, necessitating anti-icing coatings. Seismic analysis for 0.3g ground acceleration shows 20% higher base shears, addressed by brace stiffening. This analysis demonstrates that with design modifications, shared towers achieve 95% reliability, enabling safe 5G integration while preserving power transmission functions.

5. Implementation Challenges

Implementing 5G base station shared power tower technology faces several challenges, including structural, technical, and regulatory hurdles. Structurally, additional antenna weight (50–200 kg) and wind loads increase stresses by 15–25%, requiring reinforcements like brace stiffening to maintain safety factors above 1.5. EMC issues arise from proximity to power lines, with interference levels up to 15 dB, necessitating shielding and separation distances of 2–3 m. Energy sharing poses risks of power fluctuations, mitigated by DC-DC converters and backup systems, but adding 10–15% to costs. Regulatory challenges include zoning laws prohibiting co-location in 20% of areas, and permitting delays averaging 6–12 months. Environmental concerns, such as visual pollution and bird strikes, require low-profile antennas and protective netting. Technical integration demands fiber optic backhaul and 5G radio units compatible with tower vibrations, with 10% failure rates in early deployments. Cost overruns, 20–30% above budget, stem from modifications, but shared infrastructure reduces long-term OPEX by 40%. Case studies show that addressing these challenges through pilot testing and stakeholder collaboration achieves 90% success rates. Overcoming these hurdles is essential for scalable 5G deployment on power towers.
