    Summary of the 4th NPRM
    
        1. In the Second Notice of Proposed Rule Making, 61 FR 14041, March 
    29, 1996, the Commission requested comment regarding a spectrum 
    etiquette for operation in the 59-64 GHz band. The Commission provided 
    one year for a spectrum etiquette to be submitted and encouraged 
    industry to form a working group to develop a spectrum etiquette to 
    permit efficient use of the 59-64 GHz band. In response, the Millimeter 
    Wave Communications Working Group (MWCWG) was formed and proposed a 
    Spectrum Etiquette for equipment operating in the 59-64 GHz band. The 
    MWCWG proposed Spectrum Etiquette can be accessed at [http://
    www.fcc.gov/oet/dockets/et94-124/]. MWCWG seeks adoption of its 
    proposal to permit efficient use of the spectrum by enabling greater 
    frequency reuse and lowering the probability of interference.
    
    [[Page 45381]]
    
        2. The 4th NPRM seeks comment on a proposed spectrum etiquette for 
    unlicensed services in the 59-64 GHz frequency band. The proposed 
    spectrum etiquette seeks to: (1) Establish a coordination channel 
    located at 59.0-59.05 GHz to be used exclusively to establish 
    techniques that various transmitters could use to help mitigate or 
    eliminate interference; (2) establish a format for transmitter 
    identification by requiring a 60 GHz transmitter with an output power 
    of 0.1 mW or more to transmit information that contains the FCC ID 
    number, the serial number of the transmitter, and a user definable 
    field of up to 24 bytes of information; (3) adopt a limit for peak 
    equivalent isotropically radiated power of 20 W for 60 GHz 
    transmitters; (4) limit the peak transmitter output power to 500 mW; 
    and (5) limit the peak transmitter output power for transmitters 
    employing a 6 dB bandwidth of less than 100 MHz, as measured with a 100 
    kHz resolution bandwidth spectrum analyzer, according to the following 
    formula: P  500 [bandwidth in MHz/100] mW.
        3. The Commission seeks comments on whether it should adopt the 
    standards contained in the MWCWG proposal. The Commission is 
    particularly interested in comments regarding the proposed transmitter 
    identification requirements and the designation of a coordination 
    channel. The Commission wishes to clarify, however, that the reference 
    in the MWCWG filing for ``radiated power'' actually refers to 
    transmitter output power.
        4. Parties commenting on the proposed peak limits and measurements 
    should be aware of the possible application of a pulse desensitization 
    correction factor. Comments should be directed towards the specific 
    substance contained in the proposed Spectrum Etiquette and we remind 
    parties that the actual regulations adopted may differ from those 
    contained in the proposed Spectrum Etiquette.
    
    Initial Regulatory Flexibility Analysis
    
        5. Need for and Objective of the Rules. This rule making proceeding 
    is initiated to obtain comments regarding the proposed Spectrum 
    Etiquette for general unlicensed operation in the 59-64 GHz band. The 
    Commission seeks comment on a spectrum etiquette proposed by the 
    Millimeter Wave Communications Working Group for the purpose of 
    minimizing interference among general unlicensed systems operating in 
    the 59-64 GHz band.
        6. Legal Basis. The proposed action is authorized under Sections 
    4(j), 301, 302, 303(e), 303(f), 303(g), 303(r), 304 and 307 of the 
    Communications Act of 1934, as amended, 47 U.S.C. 154(i), 301, 302, 
    303(e), 303(f), 303(g), 303(r), 304 and 307.
        7. Reporting, Recordkeeping and Other Compliance Requirements. We 
    propose to establish a spectrum etiquette that would apply to and 
    minimize interference between general unlicensed systems operating in 
    the 59-64 GHz band. The spectrum etiquette will require measurements to 
    be reported to the Commission as part of the normal equipment 
    authorization process under our certification procedure.
        8. Federal Rules Which Overlap, Duplicate or Conflict With These 
    Rules. None.
        9. Description, Potential Impact and Number of Small Entities 
    Involved. We expect that multiple manufacturers will manufacture 
    transmitters to operate in the 59-64 GHz band for fixed field 
    disturbance sensors and high speed computer to computer transmission 
    systems.
        10. Any Significant Alternatives Minimizing the Impact on Small 
    Entities Consistent With Stated Objectives. None.
