Sec. 90.733 Permissible operations.
(a) Systems authorized in the 220–222 MHz band may be used:
(1)(i) For government and non-government land mobile operations, i.e., for
base/mobile and mobile relay transmissions, on a primary basis; or
(ii) For the following operations instead of or in addition to a licensee's
land mobile operations: One-way or two-way paging operations on a primary
basis by all non-Government Phase II licensees, fixed operations on a
primary basis by all non-Government Phase II licensees and all Government
licensees, one-way or two-way paging or fixed operations on a primary basis
by all non-Government Phase I licensees, except that before a non-Government
Phase I licensee may operate one-way or two-way paging or fixed systems on a
primary basis instead of or in addition to its land mobile operations, it
must meet the following requirements:
(A) A nationwide Phase I licensee must;
( 1 ) Meet its two-year benchmark for the construction of its land mobile
system base stations as prescribed in Sec. 90.725(a); and
( 2 ) Provide a new 10-year schedule, as required in Sec. 90.713(b)(3), for the
construction of the fixed and/or paging system it intends to construct
instead of, or in addition to, its nationwide land mobile system; and
( 3 ) Certify that the financial showings and all other certifications
provided in demonstrating its ability to construct and operate its
nationwide land mobile system, as required in Sec. Sec. 90.713 (b), (c) and (d),
remain applicable to the nationwide system it intends to construct
consisting of fixed and/or paging operations on a primary basis instead of,
or in addition to, its land mobile operations; or
( 4 ) In lieu of providing the requirements of paragraph (a)(1)(ii)(A)( 3 )
of this section, provide the financial showings and all other certifications
required in Sec. Sec. 90.713 (b), (c) and (d) to demonstrate its ability to
construct and operate a nationwide system consisting of fixed and/or paging
operations on a primary basis instead of, or in addition to, its land mobile
operations.
(B) A non-nationwide Phase I licensee must first meet the requirement to
construct its land mobile base station and place it in operation, or
commence service (in accordance with Sec. 90.167) as prescribed in Sec. 90.725(f) or
Sec. 90.727, as applicable.
(2) Only by persons who are eligible for facilities under either this
subpart or in the pools included in subpart B or C of this part.
(3) Except for licensees classified as CMRS providers under part 20 of this
chapter, only for the transmission of messages or signals permitted in the
services in which the participants are eligible.
(b) See Sec. 90.720 of this part for permissible operations on mutual aid
channels.
(c) For operations requiring less than a 4 kHz bandwidth, more than a single
emission may be utilized within the authorized bandwidth. In such cases, the
frequency stability requirements of Sec. 90.213 do not apply, but the
out-of-band emission limits of Sec. 90.210(f) must be met.
(d) Licensees, except for licensees authorized on Channels 161 through 170
and 181 through 185, may combine any number of their authorized, contiguous
channels (including channels derived from multiple authorizations) to form
channels wider than 5 kHz.
(e) In combining authorized, contiguous channels (including channels derived
from multiple authorizations) to form channels wider than 5 kHz, the
emission limits in Sec. 90.210(f) must be met only at the outermost edges of the
contiguous channels. Transmitters shall be tested to confirm compliance with
this requirement with the transmission located as close to the band edges as
permitted by the design of the transmitter. The frequency stability
requirements in Sec. 90.213 shall apply only to the outermost of the contiguous
channels authorized to the licensee. However, the frequency stability
employed for transmissions operating inside the outermost contiguous
channels must be such that the emission limits in Sec. 90.210(f) are met over
the temperature and voltage variations prescribed in Sec. 2.995 of this chapter.
(f) A Phase I non-nationwide licensee operating a paging base station, or a
fixed station transmitting on frequencies in the 220–221 MHz band, may only
operate such stations at the coordinates of the licensee's authorized land
mobile base station.
(g) The transmissions of a Phase I non-nationwide licensee's paging base
station, or fixed station transmitting on frequencies in the 220–221 MHz
band, must meet the requirements of Sec. Sec. 90.723(d), (g), (h), and (k), and
90.729, and such a station must operate at the effective radiated power and
antenna height-above-average-terrain prescribed in the licensee's land
mobile base station authorization.
(h) Licensees using 220–222 MHz spectrum for geophysical telemetry
operations are authorized to operate fixed stations on a secondary,
non-interference basis to licensees operating in the 220–222 MHz band on a
primary basis under the conditions that such licensees:
(1) Provide notification of their operations to co-channel non-nationwide
Phase I licensees with an authorized base station, or fixed station
transmitting on frequencies in the 220–221 MHz band, located within 45 km of
the secondary licensee's station, to co-channel, Phase II EA or Regional
licensee authorized to operate in the EA or REAG in which the secondary
licensee's station is located, and to co-channel Phase I or Phase II
nationwide licensees;
(2) Operate only at temporary locations in accordance with the provisions of
Sec. 1.931 of this chapter;
(3) Not transmit at a power level greater than one watt ERP;
(4) Not transmit from an antenna higher than 2 meters (6.6 feet) above
ground; and
(5) Not operate on Channels 111 through 120, 161 through 170, or 181 through
185.
(i) All licensees constructing and operating base stations or fixed stations
on frequencies in the 220–222 MHz band must:
(1) Comply with any rules and international agreements that restrict use of
their authorized frequencies, including the provisions of Sec. 90.715 relating
to U.S./Mexican border areas;
(2) Comply with the provisions of Sec. 17.6 of this chapter with regard to
antenna structures; and
(3) Comply with the provisions of Sec. Sec. 1.1301 through 1.1319 of this chapter
with regard to actions that may or will have a significant impact on the
quality of the human environment.
