Abstract
Systems and methods for performing a handoff of an access terminal from a macro node to a femto node are disclosed. To direct handoff of the access terminal, an identity of the femto node is determined. A femto node provided may be identified by at least a difference between the offset of a first pilot signal and the offset of a second pilot signal.
