As used in this article, the following terms shall have the meanings set forth below:
ANTENNAAny transmitting or receiving device, including whip (omnidirectional antenna), panel (directional antenna), disc (parabolic antenna) or similar device, mounted in or on a tower, monopole, building or structure and used in communications that radiate or capture electromagnetic waves, digital signals, analog signal, radio frequencies (excluding radar signals), wireless telecommunications signals or other communications signals.
ANTENNA SUPPORT STRUCTUREAny structure that is designed and constructed primarily for the purpose of supporting one or more antennas for wireless telephone, television, radio and similar communication purposes, including monopoles. Lattice and guyed towers are not permitted antenna support structures. The term includes radio and television transmission towers, microwave towers, common-carrier towers, cellular telephone towers, camouflaged tower structures, and the like. The term includes the structure and any support thereto. The term does not include wireless facilities located in or on existing buildings or structures that previously existed or are being constructed for a primary purpose other than a wireless facility, e.g., water tower, electric utility pole, or church steeple.
BASE STATION EQUIPMENTEquipment integral to the operation of an antenna system. Base station equipment typically includes, but is not limited to, communications equipment cabinet/shelter, backup power supplies, generators, electric and telecommunications backboards, wiring, grounding loops, equipment enclosures, security fencing and lighting.
CO-LOCATIONThe use of a single mount on the ground by more than one provider (vertical co-location) and/or several mounts on an existing tower, building or structure by more than one carrier for the purpose of transmitting and/or receiving radio frequency signals for communications purposes.
EQUIPMENT SHELTERAn enclosed structure associated with the mount within which is housed the base station equipment for a wireless communications facility.
FALL ZONEThe area on the ground within a prescribed radius from the base of a wireless communications facility. The fall zone is the area within which there might be a potential hazard from falling debris or collapsing material, including the antenna support structure.
HEIGHTWhen referring to a tower or other antenna support structure, the height is the distance from the top of the structure at its highest point, including antennas, lightning protection devices or any other apparatus attached to the top of the antenna support structure, to the base of the structure, measured in feet above ground level (AGL). Absolute height is the distance from the top of the structure, including all attachments, to the height of mean sea level (MSL).
LATTICE ANTENNA SUPPORT STRUCTUREAn antenna support structure that has open-framed supports on three or four sides and is constructed without guy wires and ground anchors.
MODIFICATIONThe addition, removal, or change of any of the physical and visually discernible components or aspects of a wireless facility, such as antennas, cabling, radios, equipment shelters, landscaping, fencing, utility feeds, changing the color or materials of any visually discernible components, vehicular access, parking and/or an upgrade or replacement of the equipment. Adding a new wireless carrier or service provider (co-location) to a wireless communications tower or site is a modification. Modifications also include: extending the height of the antenna support structure above its current height, changing the footprint of the structure, expansion of the base station equipment or compound area, addition of antennas to an existing carrier's antenna array, re-orientation or relocation of existing antennas, changes affecting the operating frequencies, effective radiated power or number of operating channels. A modification shall not include ordinary maintenance, as defined herein.
MONOPOLEA freestanding antenna support structure consisting of a single pole, without guy wires or ground anchors.
MOUNTThe structure or surface upon which antennas are mounted and/or the location of the antenna, e.g.:
D. FLUSH-MOUNTEDMounted very close on a building or structure so that the profile of the antenna(s) is not readily apparent.
E. INTERIOR-MOUNTEDMounted within a building or other structure so that the antennas are not visible from the outside.
ORDINARY MAINTENANCEWork done to an existing wireless telecommunications facility and antenna support structure for the purpose of maintaining them in good operating condition. Ordinary maintenance includes inspections and testing to maintain functionality, aesthetic and structural integrity, and involves the normal repair of a wireless facility including the like-for-like replacement of damaged or defective components without otherwise adding, removing, or substantially changing anything and therefore does not include modifications.
RADIO FREQUENCY (RF) SIGNALThe actual beam or radio waves sent and received by a wireless facility. A signal is the deliberate product of a wireless antenna. The RF radiation is the by-product.
WIRELESS COMMUNICATIONS FACILITYAntenna or antenna support structure and base equipment, either individually or together, including permanent or temporary movable facilities (i.e., wireless facilities mounted on vehicles, boats or other mobile structures) used for the provision of any wireless service.
WIRELESS SERVICESCommercial mobile services, unlicensed wireless services, and common-carrier wireless exchange services, including, but not limited to, voice, data, images or other information, cellular telephone service, personal communications service (PCS), enhanced specialized mobile radio (ESMR) service, and paging service.
