ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: By this action, the Commission makes available 15 new channel pairs for cordless telephones. This action is taken to relieve [[Page 21985]] congestion on existing channels and is intended to improve the operation and convenience of cordless telephones, making it easier for consumers to obtain improved wireless access to telephone service. EFFECTIVE DATE: June 5, 1995. FOR FURTHER INFORMATION CONTACT: Anthony Serafini, Office of Engineering and Technology, (202) 776-1628. SUPPLEMENTARY INFORMATION: This is a summary of the background to the Commission's Report and Order, in ET Docket 93-235, Adopted April 5, 1995 and released April 10, 1995. The complete Report and Order is available for inspection and copying during normal business hours in the FCC Reference Center (Room 239), 1919 M Street NW., Washington, DC, and also may be purchased from the Commission's duplication contractor, International Transcription Service, (202) 857-3800, 2100 M Street NW., Suite 140, Washington, DC 20037. 1. On August 20, 1992, the Personal Communications Section of the Telecommunications Industry Association (TIA) submitted a Petition for Rule Making (RM-8094) seeking additional frequencies for cordless telephones. TIA stated that additional cordless telephone channels are needed to relieve channel-crowding problems, due to the widespread popularity of these devices. TIA suggested that an additional 15 channel pairs using 30 frequencies near 44 and 49 MHz be made available for cordless telephone use. 2. On August 20, 1993, the Commission adopted a Notice of Proposed Rule Making (Notice), 58 FR 51299 (October 1, 1993), in this proceeding. In the Notice, the Commission proposed to make available for cordless telephone use the additional 15 channel pairs suggested by TIA. These frequencies are currently allocated to the Private Land Mobile Radio Service (PLMRS). The Commission also proposed to require that cordless telephones operating on these new frequencies incorporate a mechanism for automatically monitoring and preventing activation on any occupied channel. The proposed frequencies in the 44 MHz band are used internally by TV receivers. The Commission therefore proposed to designate the lower frequencies near 44 MHz, for base units in order to minimize interference to TV receivers and not to require any specific pairing of frequencies. It further requested comment on certain other technical aspects associated with cordless telephone operation. Namely, it requested comment on whether to continue to allow cordless telephone operating frequencies to be offset from the center of cordless telephone channels and whether 20 kHz is the appropriate bandwidth for operation on the new frequencies. 3. The commenting parties representing cordless telephone manufacturers agreed that there is a need for additional cordless telephone frequencies to relieve channel congestion. Some of these parties raised concerns with respect to specific technical requirements and implementation procedures. Other parties, generally representing land mobile and broadcast interest, expressed concern about potential interference problems and questioned the need for additional cordless telephone spectrum. 4. Based on these comments, the Commission adopted the Report and Order to allow new cordless telephone frequencies. Accordingly, it is ordered that Parts 15 and 90 of the Commission's rules are amended as specified below, effective 30 days after publication in the Federal Register. Furthermore, it is ordered that the Petitions for Reconsideration filed by the Telecommunications Industry Association and Uniden America Corporation in GEN Docket No. 89-626 are granted with regard to the offset channel rule. This action is taken pursuant to the authority contained in sections 4(i), 302, 303(e), 303(f), and 303(r) of the Communications Act of 1934, as amended. List of Subjects 47 CFR Part 15 Communications equipment. 47 CFR Part 90 Communications equipment. Federal Communications Commission. William F. Caton, Acting Secretary. Amendatory Text A. Title 47 of the Code of Federal Regulations, parts 15 and 90, as amended to read as follows: PART 15--RADIO FREQUENCY DEVICES 1. The authority citation for part 15 continues to read as follows: Authority: Secs. 4, 302, 303, 304, and 307 of the Communications Act of 1934, as amended, 47 U.S.C. 154, 302, 303, 304, and 307. 2. Section 15.233 is amended by revising the section heading and paragraphs (b) and (d), to read as follows: Sec. 15.233 Operation within the bands 43.71-44.49 MHz, 46.60-46.98 MHz, 48.75-49.51 MHz and 49.66-50.0 MHz. * * * * * (b) An intentional radiator used as part of a cordless telephone system shall operate centered on one or more of the following frequency pairs, subject to the following conditions: (1) Frequencies shall be paired as shown below, except that channel pairing for channels one through fifteen may be accomplished by pairing any of the fifteen base transmitter frequencies with any of the fifteen handset transmitter frequencies. (2) Cordless telephones operating on channels one through fifteen must: (i) Incorporate an automatic channel selection mechanism that will prevent establishment of a link on any occupied frequency; and (ii) The box or an instruction manual which is included within the box which the individual cordless telephone is to be marketed shall contain information indicating that some cordless telephones operate at frequencies that may cause interference to nearby TVs and VCRs; to minimize or prevent such interference, the base of the cordless telephone should not be placed near or on top of a TV or VCR; and, if interference is experienced, moving the cordless telephone farther away from the TV or VCR will often reduce or eliminate the interference. A statement describing the means and procedures used to achieve automatic channel selection shall be provided in any application for equipment authorization of a cordless telephone operating on channels one through fifteen. ------------------------------------------------------------------------ Base Handset Channel transmitter transmitter (MHz) (MHz) ------------------------------------------------------------------------ 1....................................... 43.720 48.760 2....................................... 43.740 48.840 3....................................... 43.820 48.860 4....................................... 43.840 48.920 5....................................... 43.920 49.020 6....................................... 43.960 49.080 7....................................... 44.120 49.100 8....................................... 44.160 49.160 9....................................... 44.180 49.200 10...................................... 44.200 49.240 11...................................... 44.320 49.280 12...................................... 44.360 49.360 13...................................... 44.400 49.400 14...................................... 44.460 49.460 15...................................... 44.480 49.500 16...................................... 46.610 49.670 17...................................... 46.630 49.845 18...................................... 46.670 49.860 19...................................... 46.710 49.770 20...................................... 46.730 49.875 21...................................... 46.770 49.830 22...................................... 46.830 49.890 [[Page 21986]] 23...................................... 46.870 49.930 24...................................... 46.930 49.990 25...................................... 46.970 49.970 ------------------------------------------------------------------------ * * * * * (d) The fundamental emission shall be confined within a 20 kHz band and shall be centered on a carrier frequency shown above, as adjusted by the frequency tolerance of the transmitter at the time testing is performed.
