How should I name interface and implementation projects?

I am just starting to design a new project, however I am unsure how I should be naming these projects to best allow me team to understand their function without asking.

The solution is split up into Entities, Business and Data Access.

Each of these implements a an interface from another project. The way I have named these projects before is as follows:

Entities(Implementation) -> ClientEntities (Interfaces)

DataAccess(Implementation) -> ServerEntities (Interfaces)

What would be a suitable alternative? The problem I'm trying to solve is that there is no real indication as to the purpose of these projects within the name
