A significant challenge in the development of 5G technology is the need for extensive infrastructure upgrades and investments. Deploying 5G networks requires the installation of numerous small cells to improve coverage and capacity, especially in urban areas. Additionally, ensuring interoperability with existing technologies and addressing concerns around security and health implications complicate the rollout. Regulatory hurdles and spectrum availability further exacerbate the challenges in making 5G widely accessible. Overcoming these obstacles is crucial for realizing the full potential of 5G connectivity and its transformative impact.
