PART 101_FIXED MICROWAVE SERVICES--Table of Contents

 

                      Subpart C_Technical Standards

 

Sec. 101.139  Authorization of transmitters.



    (a) Unless specified otherwise, transmitters used in the private 

operational fixed and common carrier fixed point-to-point microwave and 

point-to-multipoint services under this part must be a type that has 

been verified for compliance.

    (b) Any manufacturer of a transmitter to be produced for use under 

the rules of this part may request certification or obtain verification 

by following the applicable procedures set forth in part 2 of this 

chapter.

    (c) Certification for an individual transmitter may also be 

requested by an applicant for a station authorization, pursuant to the 

procedures set forth in part 2 of this chapter.

    (d) A transmitter presently shown on an instrument of authorization, 

which operates on an assigned frequency in the 890-940 MHz band and has 

not been certificated, may continue to be used by the licensee without 

certification provided such transmitter continues otherwise to comply 

with the applicable rules and regulations of the Commission.

    (e) Certification or verification is not required for portable 

transmitters operating with peak output power not greater than 250 mW. 

If operation of such equipment causes harmful interference the FCC may, 

at its discretion, require the licensee to take such corrective action 

as is necessary to eliminate the interference.

    (f) After July 15, 1996, the manufacturer (except for export) or 

importation of equipment employing digital modulation techniques in the 

3700-4200, 5925-6425, 6525-6875, 10,550-10,680 and 10,700-11,700 MHz 

bands must meet the minimum payload capacity requirements of Sec. 

101.141.

    (g) After April 1, 2005, the manufacture (except for export) or 

importation of equipment for operation in the 21,200-23,600 MHz band 

must meet:

    (1) The 0.001% frequency tolerance requirement for digital systems 

in Sec. 101.107(a) or the 0.03-0.003% frequency tolerance for analog 

sytems; and

    (2) For equipment employing digital modulation techniques, the 

minimum bit rate requirements of Sec. 101.141(a).

    (h) 71,000-76,000 MHz; 81,000-86,000 MHz. For equipment employing 

digital modulation techniques, the minimum bit rate requirement is 0.125 

bit per second per Hz.

    (i) 92,000-94,000 MHz; 94,100-95,000 MHz. For equipment employing 

digital modulation techniques, the minimum bit rate requirement is 1.0 

bit per second per Hz.
