((B)) ** Comparable capability of systems** For purposes of subparagraph (A), comparable capability of systems—

((i)) may be achieved by relocating a Federal Government station to a new frequency assignment, by relocating a Federal Government station to a different geographic location, by modifying Federal Government equipment to mitigate interference or use less spectrum, in terms of bandwidth, geography, or time, and thereby permitting spectrum sharing (including sharing among relocated Federal entities and incumbents to make spectrum available for non-Federal use) or relocation, or by utilizing an alternative technology; and

((ii)) includes the acquisition of state-of-the-art replacement systems intended to meet comparable operational scope, which may include incidental increases in functionality.

Unless disapproved within 30 days, the estimate shall be approved. If disapproved, the NTIA may resubmit a revised initial estimate.1

((6)) ** Implementation of procedures** The NTIA shall take such actions as necessary to ensure the timely relocation of Federal entities’ spectrum-related operations from frequencies described in paragraph (2) to frequencies or facilities of comparable capability and to ensure the timely implementation of arrangements for the sharing of frequencies described in such paragraph. Upon a finding by the NTIA that a Federal entity has achieved comparable capability of systems, the NTIA shall terminate or limit the entity’s authorization and notify the Commission that the entity’s relocation has been completed or sharing arrangement has been implemented.
