For the purposes of this chapter, the following terms, phrases, words, and their derivations shall have the meanings given herein. Words not defined shall be given their common and ordinary meaning.
ADEQUATE COVERAGE. Coverage is considered to be "adequate" within that area surrounding a WTF where the predicted or measured median field strength of transmittal signal is greater than or equal to -95dbm for at least 75% of the intended coverage area, it is acceptable for there to be holes within the area of adequate coverage where the signal is less than -95dbm, as long as the signal regains its strength to greater than or equal to - 95dbm further away from the WTF. 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 or equal to -95dbm.
ADEQUATE CAPACITY. Capacity 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 service 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 chapter shall apply only to the capacity of the radio components.
ANTENNA. Any panel, whip, dish, or other apparatus designed for communications through the sending and receiving of electromagnetic waves, excluding any support structure other than brackets.
(1) ANTENNA, PERSONAL USE. Any antenna and earth satellite dishes designed only to receive AM and FM radio, CB radio, television, and satellite television broadcast transmissions and receive and transmit amateur radio signals, for the use and enjoyment of the property owner. Such uses are an accessory use of the property and shall be governed by provisions specified in this chapter and Chapter 152.
ANTENNA SUPPORT STRUCTURE. Any building or other structure other than a tower utilized as a location for wireless telecommunications facilities.
CHANNEL. The segment of the radiation spectrum from an antenna which carries one signal. An antenna may radiate on many channels simultaneously.
CO-LOCATION. The use of a tower or antenna support structure by more than one wireless telecommunications provider.
DBM. Unit of measure of the power level of an electromagnetic signal expressed in decibels referenced to 1 milliWatt.
ELECTROMAGNETICALLY ABLE. The 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 interferences shall be considered when making this determination.
EFM. Electromagnetic frequency.
GRADE OF SERVICE. A measure of 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.
MONITORING PROTOCOL. An approved testing protocol as defined in the most current FCC regulations. As of August 15, 1997, the most current practice is referenced in FCC Regulations, Title 47, Part 1, Section 1.1307 as IEEE C95.1-1992.
ENGINEER. Any engineer licensed by the State of Ohio.
EQUIPMENT SHELTER. The structure in which the electronic receiving and relay equipment for a wireless telecommunications facility is housed.
FAA. The Federal Aviation Administration and any legally appointed, designated or elected agent or successor.
FCC. The Federal Communications Commission and any legally appointed, designated or elected agent or successor.
MONOPOLE. A structure constructed as a single, self-supporting hollow metal tube securely anchored to a foundation.
RADIATION PROPAGATION STUDIES OR RADIAL PLOTS. Computer generated estimates of the radiation emanating from antennas or repeaters sited on a specific tower or structure. The height above ground and above mean sea level, power input and output, frequency output, type of antenna, antenna gain energy dispersion characteristics, and topography of both the site and its surroundings are all taken into account to create these situations. They are the primary tool for determining whether a site will provide adequate coverage for the personal wireless telecommunications service facility proposed for that site.
RIGHT-OF-WAY. Land areas obtained by easement or deed by railroads or government entities for a public interest, to allow movement by trains or vehicles.
TOWER. A self-supporting, monopole, or guyed structure, constructed from grade, which supports wireless telecommunications facilities. The term tower shall not include amateur radio operator's equipment, as licensed by the FCC.
WIRELESS TELECOMMUNICATION FACILITY (WTF)
.
Any cables, wires, lines, wave guides, antenna(s) and any other equipment or facilities associated with the transmission or reception of communications at a particular site as authorized by the FCC which a person seeks to locate or have installed upon a tower or antenna support structure. However, the term wireless telecommunications facilities shall not include:
(1) Any satellite earth station antenna two meters in diameter or less which is located in an area zoned industrial or commercial.
(2) Any satellite earth station antenna one meter or less in diameter, regardless of zoning category.
(3) Antennas used by amateur radio operators.
(4) Antennas used as an accessory use of a property for the purpose of receiving AM and FM radio transmissions, and television transmissions. Such antennas shall not exceed the lesser of the following:
(a) Height of the existing principle structure by 20 feet.
(b) Maximum height of the zoning district by 20 feet.
