For purposes of Subsection
C(2), the following definitions apply:
BASE STATIONA structure or equipment at a fixed location that enables Commission-licensed or authorized wireless communications between user equipment and a communications network. The term does not encompass a tower, as defined in this subsection, or any equipment associated with a tower.
[1] The term includes, but is not limited to, equipment associated with wireless communications services such as private, broadcast, and public safety services, as well as unlicensed wireless services and fixed wireless services such as microwave backhaul.
[2] The term includes, but is not limited to, radio transceivers, antennas, coaxial or fiber optic cable, regular and backup power supplies, and comparable equipment, regardless of technological configuration (including distributed antenna systems and small-cell networks).
[3] The term includes any structure other than a tower that, at the time the relevant application is filed with the state or local government under this section, supports or houses equipment described in Subsection C(2)(b)[1] through [2] of this section that has been reviewed and approved under the applicable zoning process, or under another state or local regulatory review process, even if the structure was not built for the sole or primary purpose of providing such support.
[4] The term does not include any structure that, at the time the relevant application is filed with the state or local government under this section, does not support or house equipment described in Subsection C(2)(b)[1] through [2] of this section.
CO-LOCATIONThe mounting or installation of transmission equipment on an eligible support structure for the purpose of transmitting and/or receiving radio frequency signals for communications purposes.
ELIGIBLE FACILITIES REQUESTAny request for modification of an existing tower or base station that does not substantially change the physical dimensions of such tower or base station, involving:
[1] Co-location of new transmission equipment;
[2] Removal of transmission equipment; or
[3] Replacement of transmission equipment.
ELIGIBLE SUPPORT STRUCTUREAny tower or base station as defined in this section, provided that it is existing at the time the relevant application is filed with the state or local government under this section.
EXISTINGA constructed tower or base station is existing, for purposes of this section, if it has been reviewed and approved under the applicable zoning process, or under another state or local regulatory review process is existing for purposes of this definition.
SITEFor towers other than towers in the public rights-of-way, the current boundaries of the leased or owned property surrounding the tower and any access or utility easements currently related to the site, and for other eligible support structures, further restricted to that area in proximity to the structure and to other transmission equipment already deployed on the ground.
SUBSTANTIAL CHANGEA modification substantially changes the physical dimensions of an eligible support structure if it meets any of the following criteria:
[1] For towers other than towers in the public rights-of-way, it increases the height of the tower by more than 10% or by the height of one additional antenna array with separation from the nearest existing antenna not to exceed 20 feet, whichever is greater; for other eligible support structures, it increases the height of the structure by more than 10% or more than 10 feet, whichever is greater. Changes in height shall be measured from the original support structure in cases where deployments are or will be separated horizontally, such as on buildings' rooftops; in other circumstances, changes in height shall be measured from the dimensions of the tower or base station, inclusive of originally approved appurtenances and any modifications that were approved prior to the passage of the Spectrum Act;
[2] For towers other than towers in the public rights-of-way, it involves adding an appurtenance to the body of the tower that would protrude from the edge of the tower more than 20 feet, or more than the width of the tower structure at the level of the appurtenance, whichever is greater; for other eligible support structures, it involves adding an appurtenance to the body of the structure that would protrude from the edge of the structure by more than six feet;
[3] For any eligible support structure, it involves installation of more than the standard number of new equipment cabinets for the technology involved, but not to exceed four cabinets; or for towers in the public rights-of-way and base stations, it involves installation of any new equipment cabinets on the ground if there are no preexisting ground cabinets associated with the structure, or else involves installation of ground cabinets that are more than 10% larger in height or overall volume than any other ground cabinets associated with the structure;
[4] It entails any excavation or deployment outside the current site;
[5] It would defeat the concealment elements of the eligible support structure; or
[6] It does not comply with conditions associated with the local approval of the construction or modification of the eligible support structure or base station equipment; provided, however, that this limitation does not apply to any modification that is noncompliant only in a manner that would not exceed the thresholds identified in § 1.40001(b)(7)(i) through (iv).
TOWERAny structure built for the sole or primary purpose of supporting any Federal Communications Commission-licensed or authorized antennas and their associated facilities, including structures that are constructed for wireless communications services, including, but not limited to, private, broadcast, and public safety services, as well as unlicensed wireless services and fixed wireless services such as microwave backhaul, and the associated site.
TRANSMISSION EQUIPMENTEquipment that facilitates transmission for any Federal Communications Commission-licensed or authorized wireless communication service, including, but not limited to, radio transceivers, antennas, coaxial or fiber optic cable, and regular and backup power supply. The term includes equipment associated with wireless communications services including, but not limited to, private, broadcast, and public safety services, as well as unlicensed wireless services and fixed wireless services such as microwave backhaul.
