As used in this article, the following terms shall have the meanings indicated:
ADEQUATE CAPACITYCapacity is considered to be "adequate" if the grade of service (GOS) is p.05 or better for median traffic levels offered during the typical busy hour, as assessed by direct measurement of the personal wireless facility or regulated facility in question. The GOS shall be determined by the use of standard Erlang B calculations. As call blocking may occur in either the land line or radio portions of a wireless network, adequate capacity for this regulation shall apply only to the capacity of the radio components. Where capacity must be determined prior to the installation of the personal wireless service facility or regulated facility in question, adequate capacity shall be determined on the basis of a 20% busy hour (20% of all offered traffic occurring within the busiest hour of the day), with total daily traffic based on aggregate estimates of the expected traffic in the coverage area.
ADEQUATE COVERAGECoverage is considered to be "adequate" within that area surrounding a base station where the predicted or measured median field strength of the transmitted signal is such that the majority of the time, transceivers properly installed and operated will be able to communicate with the base station. In the case of cellular communications in a rural area like Haddam, this would be a signal strength of at least -90 dBm for at least 75% of the coverage area. It is acceptable for there to be holes within the area of adequate coverage where the signal is less than -90 dBm, as long as the signal regains its strength to greater than -90 dBm further away from the base station. The outer boundary of the area of adequate coverage is that location past which the signal does not regain strength of greater than -90 dBm.
ANTENNAThe surface from which wireless radio signals are sent and received by a personal wireless service facility or regulated facility.
CAMOUFLAGED OR STEALTH FACILITYA wireless communication regulated facility that is disguised, hidden, part of an existing or proposed structure, or placed within an existing or proposed structure.
CARRIERA company that provides wireless services.
CO-LOCATIONThe use of a single mount on the ground by more than one carrier (vertical co-location) and/or several mounts on an existing building or structure by more than one carrier.
COMMISSIONThe Planning and Zoning Commission of the Town of Haddam.
ELEVATIONThe elevation at grade or ground level shall be given in "above mean sea level" (AMSL). The height of a wireless service facility shall be given in "above ground level" (AGL). AGL is a measurement of height from the natural grade of a site to the highest point of a structure. The total elevation of the wireless service facility is AGL plus AMSL.
ENVIRONMENTAL ASSESSMENT (EA)The document required by the Federal Communications Commission (FCC) and the National Environmental Policy Act (NEPA) when a wireless communication facility or regulated facility is placed in certain designated areas.
ENVIRONMENTAL IMPACT STATEMENT (EIS)A report which shall evaluate the existing conditions of the proposed regulated facility and the full impact of construction on the existing conditions, terrestrial ecology, environmental setting and cultural resources through the actions of grading, soil disturbance, facility construction, site drainage and any other above- or below-ground disturbance.
EQUIPMENT SHELTERAn enclosed structure, cabinet, shed or box at the base of the mount within which are housed batteries and electrical equipment necessary for the operation of the communication facility or regulated facility.
FALL ZONEThe area on the ground within a prescribed radius from the base of a wireless communication facility or regulated facility. The fall zone is the area within which there is a potential hazard from falling debris (such as ice) or collapsing material.
GUYED REGULATED FACILITYA monopole or existing lattice tower that is tied to the ground or other surface by diagonal cables.
LATTICE REGULATED FACILITYA type of mount that is self-supporting with multiple legs and cross-bracing of structural steel for an existing lattice tower.
LICENSED CARRIERA company authorized by the FCC to construct and operate a wireless communication facility or regulated facility.
MONOPOLE TOWERA regulated facility that involves a type of mount that is self-supporting with a single shaft of wood, steel or concrete and a platform (or racks) for panel antennas arrayed at the top.
MOUNTThe structure or surface of a regulated facility upon which antennas are mounted, including the following four types of mounts:
A. Roof-mounted: mounted on the roof of a building.
B. Side-mounted: mounted on the side of a building.
C. Ground-mounted regulated facility: mounted on the ground.
D. Structure-mounted: mounted on a structure other than a building.
PANEL ANTENNAA flat-surface antenna usually developed in multiples such as whip antennas, panel antennas, and dish antennas.
PROPAGATION STUDIES or COVERAGE PLOTSComputer-generated estimates of the signal emanating, and prediction of coverage, from antennas or repeaters sited on a specific regulated facility structure. The height above ground, power input and output, frequency output, type of antenna, antenna gain, topography of the site and its surroundings are all taken into account to create these simulations. They are the primary tool for determining whether a site will provide adequate coverage for the telecommunication facility proposed for the site.
REGULATED FACILITYAll regulated facilities as defined by this section, including mounts, towers and antennas, service and/or sites where these facilities are proposed or exist, or service is to be provided from, relating to personal communication services and any other wireless telecommunication service subject to local zoning regulation. A regulated facility, service and/or site includes, but is not limited to, a proposed co-located regulated facility, service and/or site.
REPEATERA small receiver/relay transmitter of not more than 20 watts' output designed to provide service to areas which are not able to receive adequate coverage directly from a base station.
SECURITY BARRIERA locked, impenetrable wall, fence or berm that completely seals an area from unauthorized entry or trespass.
SEPARATIONThe distance between one carrier's array of antennas and another carrier's array.
