Sec. 25.212  Narrowband transmissions in the Fixed-Satellite Service.

    (a) Except as otherwise provided by this part, criteria for 
unacceptable levels of interference caused by other satellite networks 
shall be established on the basis of nominal operating conditions and 
with the objective of minimizing orbital separations between satellites.
    (b) Emissions with an occupied bandwidth of less than 2 MHz are not 
protected from interference from wider bandwidth transmissions if the 
r.f. carrier frequency of the narrowband signal is within &177;1 
MHz of one of the frequencies specified in Sec. 25.211(a).
    (c) In the 14 GHz band, an earth station with an equivalent diameter 
of 1.2 meters or greater may be routinely licensed for transmission of 
narrowband analog services with bandwidths up to 200 kHz if the maximum 
input power density into the antenna does not exceed -8 dBW/4 kHz and 
the maximum transmitted satellite carrier EIRP density does not exceed 
13 dBW/4 kHz, and for transmission of narrowband and/or wideband digital 
services, if the maximum input power density into the antenna does not 
exceed -14 dBW/4 kHz and the maximum transmitted satellite carrier EIRP 
density does not exceed +6.0 dBW/kHz.
    (d) In the 6 GHz band, an earth station with an equivalent diameter 
of 4.5 meters or greater may be routinely licensed for transmission of 
SCPC services if the maximum power densities into the antenna do not 
exceed +0.5 dBW/4 kHz for analog SCPC carriers with bandwidths up to 200 
kHz, and do not exceed -2.7 dBW/4 kHz for narrow and/or wideband digital 
SCPC carriers.
