5G fragmentation happens because of various factors, such as the diversity of 5G use cases, the complexity of 5G technology, the competition among 5G stakeholders, and the regulatory and policy differences among 5G regions. For example, 5G use cases range from enhanced mobile broadband to massive IoT to ultra-reliable low-latency communications, each requiring different network architectures, frequencies, and capabilities. Similarly, 5G technology involves multiple layers, components, and interfaces, such as radio access network, core network, edge computing, network slicing, and orchestration, each posing technical and operational challenges. Moreover, 5G stakeholders, such as vendors, operators, and regulators, have different interests, strategies, and priorities, leading to divergent and sometimes conflicting approaches to 5G deployment and management. Finally, 5G regions, such as North America, Europe, Asia, and Africa, have different regulatory and policy frameworks, affecting the availability, affordability, and accessibility of 5G spectrum, infrastructure, and services.
