Fiber to the 5G small cell – FTT5G: A Survey

The deployment of 5G networks requires high-capacity, low-latency connectivity to support the increasing demands of modern communication services. Fiber to the 5G small cell (FTT5G) has emerged as a crucial solution, enabling efficient small cell deployment by leveraging fiber-optic networks for reliable backhaul and fronthaul connectivity. This paper provides a comprehensive survey of FTT5G architectures, deployment strategies, and technical challenges, with a focus on Fiber-to-the-Home (FTTH) and Fiber-to-the-X (FTTx) solutions. The study highlights the role of fiber in addressing the bandwidth and scalability challenges of 5G small cell networks, ensuring seamless data transmission for next-generation applications. Additionally, the paper examines the economic and regulatory aspects of fiber deployment and explores strategies for cost-efficient network expansion. By offering insights into the integration of optical and wireless technologies, this survey serves as a valuable resource for researchers, industry professionals, and policymakers aiming to optimize fiber-based 5G infrastructure and enhance network performance.
