§ 22.859 Incumbent commercial aviation air-ground systems.
This section contains rules concerning continued operation of
commercial aviation air-ground systems that were originally authorized
prior to January 1, 2004 to provide radiotelephone service using
narrowband (6 kHz) channels, and that have been providing service
continuously since the original commencement of service (hereinafter
(a) An incumbent system may continue to operate under its
authorization, for the remaining term of such authorization, subject to
the terms and conditions attached thereto. Wherever such technical and
operational conditions differ from technical and operational rules in
this subpart, those conditions shall govern its operations.
(b) Notwithstanding any other provision in this chapter, the licensee
of an incumbent system shall not be entitled to an expectation of
renewal of said authorization.
(c) During the period that an incumbent system continues to operate and
provide service pursuant to paragraph (a) of this section, air-ground
systems of licensees holding a new authorization for the spectrum
within which the incumbent system operates must not cause interference
to the incumbent system. Protection from interference requires that the
signals of the new systems must not exceed a ground station received
power of −130 dBm within a 6 kHz receive bandwidth, calculated assuming
a 0 dBi vertically polarized receive antenna.
