[Added 4-1-2008 by Ord. No. 1545]
A.
Except as otherwise provided, no person shall maintain,
own, erect, construct, remodel, renovate, or provide an addition of
more than 20% to any building or structure or any part thereof or
cause the same to be done which fails to support adequate radio coverage
for the Sarpy County Radio Communications System (SCRCS), including
but not limited to emergency service workers, firefighters and police
officers. Descriptively, adequate coverage means the ability for SCRCS
users to transmit into the building an intelligible voice signal that
may be heard; the ability to receive an intelligible voice signal
transmitted and originating from within the building; and the ability
to transmit and receive intelligible voice signals among users who
are within the building.
B.
For purposes of this article, adequate radio coverage
shall include all of the following:
(1)
A minimum received signal strength in the building
of one microvolt (-107 dBm) available in 90% of the area of each floor
when transmitted from the SCRCS;
(2)
A minimum signal strength of one microvolt (-107 dBm)
received by the SCRCS when transmitted from 90% of the area of each
floor of the building;
(3)
The frequency range that must be supported shall be
806 MHz to 869 MHz; and
(4)
A ninety-percent reliability factor shall be required.
A.
Initial tests.
(1)
It will be the building owner's responsibility to
have the building tested to ensure that two-way coverage on each floor
of the building is a minimum of 90%. At a minimum, the test shall
be conducted using a Motorola MTS 2000, or equivalent portable radio,
talking through the SCRCS. Radios may be obtained for conduct of the
tests from the Sarpy County Communications Department (SCCD). The
gain values of all amplifiers shall be measured and the test measurement
results shall be provided to the SCCD and kept on file so that the
measurements can be verified each year during the annual tests. The
SCCD will be informed of the schedule for such testing and, at its
discretion, may participate as an observer.
(2)
A certificate of occupancy shall not be issued to
any structure if the building fails to comply with this section.
Buildings and structures that cannot support
the required level of radio coverage shall be equipped with any of
the following in order to achieve the required adequate radio coverage:
a radiating cable system or an internal multiple-antenna system with
or without FCC-accepted bidirectional amplifiers as needed. If used,
bidirectional amplifiers shall include filters to reduce adjacent
frequency interference at least 35 dB below the National Public Safety
Planning Advisory Committee (NPSPAC) band. The filters shall be tuned
to 825 MHz and to 870 MHz so that they will be 35 dB below the NPSPAC
frequencies of 824 MHz and 869 MHZ, respectively. Other settings may
be used, provided that they do not attenuate the NPSPAC frequencies,
and further provided that they are not more than one MHz from the
NPSPAC frequencies. If any part of the installed system or systems
contains an electrically powered component, the system shall be capable
of operating on an independent battery and/or generator system for
a period of at least 12 hours without external power input. The battery
system shall automatically charge in the presence of an external power
input.
SCCD personnel, after providing reasonable notice
to the owner or his representative, shall have the right to enter
onto the property to conduct field testing to ascertain the required
level of radio coverage is present.
This article shall not apply to buildings permitted
in residential districts; any building constructed of wood frame;
any building 35 feet high or less; as long as none of the aforementioned
buildings make use of any metal construction or any underground storage
or parking areas. For purposes of this section, parking structures
and stairwells are included in the definition of "building" and stair
shafts are included in the definition of "all parts of a building,"
but elevators may be excluded.
