As used in this personal wireless service facilities article, the following terms shall have the meanings indicated:
ACTThe Telecommunications Act of 1996.
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 greater than —95 dbm. It is acceptable for there to be holes within the area of adequate coverage where the signal is less than —95 dbm, as long as the signal regains its strength to greater than —95 dbm further away from the base station. For the limited purpose of determining whether the use of a repeater is necessary or desirable, there shall be deemed not to be adequate coverage within said holes. The outer boundary of the area of adequate coverage, however, is that location past which the signal does not regain a strength of greater than —95 dbm.
ADEQUATE CAPACITYCapacity is considered to be adequate if the grade of service is p.05 or better for at least 50% of the days in a preceding month, prior to the date of application, as measured using direct traffic measurement of the personal wireless service facility in question, where the call blocking is due to frequency contention at the antenna(s).
ANTENNAA device which is attached to a tower, or other structure for transmitting and receiving electromagnetic waves.
AVAILABLE SPACEThe space on a tower or structure to which antennas of a personal wireless service provider are both structurally able and electromagnetically able to be attached.
BASE STATIONThe primary sending and receiving site in a wireless telecommunications network. More than one base station and/or more than one variety of personal wireless service providers can be located on a single tower or structure.
CHANNELThe segment of the radiation spectrum from an antenna, which carries one signal. An antenna may radiate on many channels simultaneously.
COMMUNICATION EQUIPMENT SHELTERA structure at a base station designed principally to enclose equipment used in connection with personal wireless service transmissions.
DBMUnit of measure of the power level of an electromagnetic signal expressed in decibels referenced to one milliwatt.
ELECTROMAGNETICALLY ABLEThe determination that the new signal from and to the proposed new antennas will not significantly interfere with the existing signals from and to other facilities located on the same tower or structure as determined by a qualified professional telecommunications engineer. The use of available technologies to alleviate such interference shall be considered when making this determination.
EMFElectromagnetic Frequency Radiation.
FACILITY SITEA property, or any part thereof, which is owned or leased by one or more personal wireless service providers and upon which one or more personal wire service facility(ies) and required landscaping are located.
FCCFederal Communication Commission; the government agency responsible for regulating telecommunications in the United States.
GRADE OF SERVICEA measure of the percentage of calls which are able to connect to the base station, during the busiest hour of the day. Grade of service is expressed as a number, such as p.05 (which means that 95% of callers will connect on their first try). A lower number (p.04) indicates a better grade of service.
HERTZOne hertz is the frequency of an electric or magnetic field, which reverses polarity once each second, or one cycle per second.
MAJOR MODIFICATION OF AN EXISTING FACILITYAny change, or proposed change in power input or output, number of antennas, change in antenna type or model, repositioning of antenna(s), change in number of channels per antenna above the maximum number approved under an existing special permit.
MONITORINGThe measurement, by the use of instruments in the field, of the radiation from a site as a whole, or from individual personal wireless facilities, towers, antennas or repeaters.
MONITORING PROTOCOLThe testing protocol, initially the Cobbs Protocol, which is to be used to monitor the emissions from existing and new personal wireless service facilities upon adoption of this bylaw. As the technology changes, the SPGA may require, by written regulation, the use of other testing protocols. A copy of the monitoring protocol shall be on file with the Dalton Board of Appeals and the Dalton Town Clerk.
MONOPOLEA single self-supporting vertical pole with no guy wire anchors, usually consisting of a galvanized or other unpainted metal, or a wooden pole with below grade foundations.
PERSONAL WIRELESS SERVICECommercial mobile services, unlicensed wireless services, and common carrier wireless exchange services. These services include: cellular services, personal communication services (PCS), specialized mobile radio services and paging services.
PERSONAL WIRELESS SERVICE FACILITYAll equipment (including any repeaters) with which a personal wireless service provider broadcasts and receives the radio-frequency waves which carry their services and all locations of said equipment or any part thereof. This facility may be sited on one or more towers or structure(s) owned and permitted by another owner or entity.
RADIATION PROPAGATION STUDIES OR RADIAL PLOTSComputer generated estimates of the radiation emanating from antennas or repeaters sited on a specific tower or 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 tools for determining whether a site will provided adequate coverage for personal wireless services facilities proposed for the 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.
STRUCTURALLY ABLEThe determination that a tower or structure is capable of carrying the load imposed by the proposed new antennas under all reasonably predictable conditions as determined by professional structural engineering analysis.
TELEPORTA facility utilizing satellite dishes of greater than 2.0 meters in diameter designed to uplink to communications satellites for transmitting in the C-band (4-6 GHz) spectrum.
TOWERA lattice structure or framework, or monopole, that is designed to support personal wireless service transmission, receiving and/or relaying antennas and/or equipment.
