         OFFICE OF ENGINEERING AND TECHNOLOGY DECLARES TIME DOMAIN
    CORPORATION REQUEST FOR A WAIVER OF PART 15 FOR AN ULTRA-WIDEBAND
             SYSTEM TO BE A "PERMIT-BUT-DISCLOSE" PROCEEDING
                          FOR EX PARTE PURPOSES


        On February 2, 1998, Time Domain Corporation filed a petition for waiver of several sections
of Part 15 of the rules in order to permit the authorization, importation and operation of an ultra-
wideband system that could be used by public safety personnel for communications purposes and for
through-wall imaging radar systems.

        These transmission systems are centered within the 2-4 GHz band and occupy several gigahertz
of spectrum.  Accordingly, Time Domain seeks to operate in the restricted bands, shown in Section
15.205.  Time Domain also seeks to remove the requirement to apply a pulse desensitization correction
factor in measuring the emission from its system.  Time Domain indicates that it will comply with the
general emission limits in Section 15.209.

        The Office of Engineering and Technology (OET) is reviewing the request to determine whether
a waiver of the rules should be granted.  OET seeks comments from interested parties concerning this
request.  OET has concluded that in order to permit a fuller exchange on the complex issues under
consideration in this proceeding, it should be treated, for ex parte purposes, as a "permit-but-disclose"
proceeding, in accordance with Section 1.1200(a) of the Commission's rules, and is subject to the
requirements under Section 1.1206(b) of the rules.  Parties should note that these rule sections were
revised in a recent Report and Order, GC Docket No. 95-21, 62 Fed. Reg. 15852 (April 3, 1997).

        Interested parties filing comments or oppositions to this petition are invited to do so no later than
March 9, 1998.  Parties filing replies may do so by March 24, 1998.

        The full text of the waiver request is available for inspection and copying during normal business
hours in the OET Reception Area, Suite 480, 2000 M Street, N.W., Washington, D.C., and may also
be purchased from the Commission's duplication contractor, International Transcription Service, (202)
