Spectrum, Requirements, and Trends of 5G
Abstract
The spectrum allocation for 5G is a critical factor in the successful deployment of next-generation wireless networks, influencing the efficiency, coverage, and capacity of 5G services. It involves balancing sub-1 GHz, mid-range (1-6 GHz), and high-frequency millimeter-wave bands (above 6 GHz) to meet diverse application needs. While lower frequency bands provide broader coverage for rural areas, high-frequency millimeter waves enable ultra-fast data rates essential for urban and industrial use cases like augmented reality and autonomous vehicles. Global regulatory bodies, such as the ITU-R, are pivotal in defining the spectrum frameworks for 5G, focusing on the 24-86 GHz range to support various applications. These efforts ensure timely deployment and address challenges like spectrum allocation, fair access, and non-discriminatory authorization models. Regulatory bodies face the challenge of establishing equitable spectrum authorization models to ensure fair access for stakeholders” (ITU-R, 2019)
