Closed subscriber group (original) (raw)

A closed subscriber group (CSG) is a limited set of users with connectivity access to a femtocell. When a femtocell is configured in CSG mode, only those users included in the femtocell's access control list are allowed to use the femtocell resources.On the other hand, a femtocell can be also configured in Open Access mode, in which any user is allowed access to the femtocell.
