Remote trans-national access is access to resources and services offered by the infrastructure/facility/installation without Users physically visiting the infrastructure/facility/installation.
Similar to Physical access, it requires competitive selection of the users to be served under the GA as usually it applies to resources that are not unlimited (e.g. computing hours on a supercomputer, digital tools or measurements/experiments performed by the facility staff for the user).
On the contrary, virtual access is wide, free access provided through communication networks to resources that can be simultaneously used by an unlimited number of users (e.g. a dataset available on the Data Centre).
