5G Network Coverage Planning and Analysis of the Deployment Challenges

Area of Science:

• Telecommunications Engineering
• Wireless Communication Systems
• Network Infrastructure

Background:

• 5G cellular networks utilize mid-frequency bands (3-6 GHz) for enhanced performance and high-frequency bands (24-100 GHz) for greater capacity and lower latency.
• High-frequency bands in 5G experience significant propagation loss, limiting cell site radius to approximately 100 meters.
• Mobile network operators face challenges in planning and acquiring numerous small cell sites for uniform 5G coverage.

Purpose of the Study:

• To describe 5G coverage planning using traditional three-sector cells.
• To propose an improved cell architecture for enhanced 5G coverage.
• To identify challenges and future research directions in 5G network deployment.

Main Methods:

• Analysis of traditional three-sector cell architecture for 5G coverage planning.
• Proposal of an updated six-sector cell architecture.
• Integration of an advanced antenna system within the proposed architecture.

Main Results:

• The proposed six-sector cell architecture with advanced antennas offers improved 5G coverage compared to traditional designs.
• The study highlights the necessity of dense small cell deployment for high-frequency 5G bands.
• Significant challenges exist in site acquisition and planning for massive 5G infrastructure.

Conclusions:

• A six-sector cell architecture presents a viable solution for optimizing 5G coverage.
• Addressing deployment challenges requires innovative planning and advanced antenna technologies.
• Further research is needed to refine 5G network deployment strategies and ensure ubiquitous coverage.
