Sec. 15.319 General technical requirements.
(a) [Reserved]
(b) All transmissions must use only digital modulation techniques.
(c) Peak transmit power shall not exceed 100 microwatts multiplied by
the square root of the emission bandwidth in hertz. Peak transmit
power must be measured over any interval of continuous transmission
using instrumentation calibrated in terms of an rms-equivalent
voltage. The measurement results shall be properly adjusted for any
instrument limitations, such as detector response times, limited
resolution bandwidth capability when compared to the emission
bandwidth, sensitivity, etc., so as to obtain a true peak measurement
for the emission in question over the full bandwidth of the channel.
(d) Power spectral density shall not exceed 3 milliwatts in any 3 kHz
bandwidth as measured with a spectrum analyzer having a resolution
bandwidth of 3 kHz.
(e) The peak transmit power shall be reduced by the amount in decibels
that the maximum directional gain of the antenna exceeds 3 dBi.
(f) The device shall automatically discontinue transmission in case of
either absence of information to transmit or operational failure. The
provisions in this section are not intended to preclude transmission
of control and signaling information or use of repetitive codes used
by certain digital technologies to complete frame or burst intervals.
(g) Notwithstanding other technical requirements specified in this
subpart, attenuation of emissions below the general emission limits in
Sec. 15.209 is not required.
(h) Where there is a transition between limits, the tighter limit
shall apply at the transition point.
(i) Unlicensed PCS devices are subject to the radiofrequency radiation
exposure requirements specified in Sec. Sec. 1.1307(b), 2.1091 and 2.1093 of
this chapter, as appropriate. All equipment shall be considered to
operate in a "general population/uncontrolled" environment.
Applications for equipment authorization of devices operating under
this section must contain a statement confirming compliance with these
requirements for both fundamental emissions and unwanted emissions.
Technical information showing the basis for this statement must be
submitted to the Commission upon request.
