# 6G Use Cases and Scenarios: A Comparison Analysis Between ITU and Other Initiatives
## 4 6G Industry Association (6G-IA)  
The 6G-IA is an initiative by European Industry and Research, and it represents private companies of 5G PPP and the Smart Networks and Services Joint Undertaking (SNS-JU) [12]. It focuses on future communication networks and services, and it aims to contribute to European leadership in BY5G/6G research and development. The 6G is considered a transformative technology that will revolutionize the way enterprises operate and do business. It will enable convergence in areas such as connectivity, robotics, intelligent transport systems, cloud, and secure commerce. 6G will also create universal digital replications of real-world entities and advanced emulation platforms, allowing for Digital Twinning in various sectors, e.g., manufacturing, smart city, etc. In the case of the transportation system, the possibility of emulating in the lab a communication system to manage and control a vehicle (e.g., a train) is very important in developing and testing the communication system before its test on the field, [13]. This approach can reduce the costs for the development of the system and the new related services. The widespread deployment of 5G has led to a new era with distributed cell-free networks operated by millions of players. The need for the remote operation of converged ICT and OT platforms will require the optimization of fixed-wireless connectivity infrastructure. The differentiation between 6G and 5G focuses on global solutions that require significant \begin{table}

Regulations, such as multi-level net neutrality, will be needed to ensure fair competition and open access to 6G specialized connectivity. The indications and opinions of the 6G-IA members are detailed in [14] along with potential services, related use cases, and key strategies. The key strategies that have been identified are listed in the following points:  
* 6G Technological Sovereignty, in terms of components and microelectronics, open SNS solutions, cloudification and distributed computing, network intelligence, security and privacy, and knowledge base;
* Environmental, societal, and economic sustainability (according to UN SDGs).
