As used in this chapter, the following words are defined as
follows:
The Telecommunications Act of 1996.
Capacity is considered to be "adequate" if the grade of service
is p.02 or better based on the Erlang "B" formula 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).
Coverage is considered to be "adequate" within that area
surrounding a base station where the predicted or measured median
field strength of the transmittal signal is greater than or equal
to -95 dbm 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 -95 dbm, as long as the signal regains its strength
to greater than or equal to -95 dbm farther 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 or equal to -95 dbm.
A device which is attached to a tower or other structure, for transmitting and receiving electromagnetic waves, including, but not limited to, the transmitting and receiving of electromagnetic waves in conjunction with radio and television services. For the purpose of Article IV, this term shall not include antennas which are incidental to an accessory use.
The 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 and which is available for
rental to the applicant at fair market prices and terms, and on which
space and location will provide necessary coverage.
The primary sending and receiving site in a wireless telecommunications
network. More than one base station and/or more than one variety of
personal wire service provider can be located on a single tower or
structure.
The segment of the radiation spectrum from an antenna which
carries one signal. An antenna may radiate on many channels simultaneously.
A structure located at a base station designed principally
to enclose equipment used in connection with personal wireless service
transmissions.
Unit of measure of the power level of an electromagnetic
signal expressed in decibels referenced to one milliwatt.
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 telecommunications engineer. The use
of available technologies to alleviate such interferences shall be
considered when making this determination.
Electromagnetic field.
Effective radiated power.
A 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 wireless service facility(ies) and required landscaping
are located.
The Federal Communications Commission, the government agency
responsible for regulating telecommunications in the United States.
One billion hertz.
A 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.02, which means that 98% of callers
will connect on their first try. A lower number (p.01) indicates a
better grade of service.
One hertz is the frequency of an electric or magnetic field
which reverses polarity once each second, or one cycle per second.
Any change in maximum power input or output and/or number
of channels or number of antennas and/or change in operating frequency
approved under an existing special permit or site plan.
Any change, or proposed change, in power input or output,
number of antennas, change in antenna(s) type or model, repositioning
of antenna(s), change in number of channels per antenna above the
maximum number approved under an existing special permit. Also, any
increase or proposed increase in dimensions of an existing and permitted
tower or other structure designed to support personal wireless service
transmission, receiving and/or relaying antennas and/or equipment.
One million hertz.
The measurement, by the use of instruments in the field,
of the electromagnetic radiation from a site as a whole, or from individual
personal wireless service facilities, towers, antennas or repeaters.
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 I, Section 1.1307
as IEEE C95.3 1991. The ZBA may, as the technology changes, require
by written regulation the use of other testing protocols. A copy of
the monitoring protocol shall be on file with the Town Clerk.
Commercial mobile services, unlicensed wireless services,
and common carrier wireless exchange access services, which services
are regulated by the FCC in accordance with and as the term "personal
wireless service" is defined in the Communications Act of 1934, as
amended by the Telecommunications Act of 1996, 47 U.S.C. § 332(c)(7)(C),
or as hereafter amended. These services include cellular services,
personal communications services (PCS), specialized mobile radio services,
and paging services.
Any equipment used in connection with the commercial operation
of a personal wireless service facility as defined in the Communications
Act of 1934, as amended by the Telecommunications Act of 1996, 47
U.S.C. § 332(c)(7)(C), or as hereafter amended, to transmit
and/or receive frequencies, including, but not limited to, antennas,
monopoles, equipment, appurtenances, and structures.
An entity licensed by the FCC to provide personal wireless
services.
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(s), antenna(s) gain energy dispersion
characteristics, and topography of both 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 personal wireless telecommunications service facility
proposed for that site.
A small receiver/relay transmitter of not more than 20 watts'
output designed to extend service to areas which are not able to receive
adequate coverage directly from a base station, using the same channels
as the base station.
A static construction or an assembly of materials, the use
or occupancy of which requires a fixed location on the ground or attachment
to an object having a fixed location.
An unstaffed facility in connection with the commercial operation
of a personal wireless services facility as defined in the Communications
Act of 1934, as amended by the Telecommunications Act of 1996, 47
U.S.C. § 332(c)(7)(C). Such facility usually consists of
an equipment shelter, a support structure and/or other transmission
and reception devices.
A lattice structure framework, or monopole, that is designed
to support personal wireless service or other communications system,
transmission, receiving and/or relaying antennas and/or equipment.
A facility utilizing satellite dishes of greater than 2.0
meters in diameter designed for two-way communications with satellites,
and intended for use by multiple owners, lessees or rental customers.
The Zoning Board of Appeals of the Town of Stockport.
