The Central Government may, to promote optimal use of the available spectrum, assign a particular part of a spectrum that has already been assigned to an entity, known as the primary assignee, to one or more additional entities, known as the secondary assignees, where such secondary assignment does not cause harmful interference in the use of the relevant part of the spectrum by the primary assignee, subject to such terms and conditions as may be prescribed.

The Central Government may, notwithstanding anything contained in any other law for the time being in force, after providing a reasonable opportunity of being heard to the assignee concerned, determines that any assigned spectrum has remained unutilised for insufficient reasons for such period as may be prescribed, terminate such assignment, or a part of such assignment, or prescribe further terms and conditions relating to spectrum utilisation.
