          File No. 0060—EX—ST—1998
          Expedited Treatment Requested


Dear Sir/Madame:

        Pursuant to Sections 5.56, 5.57(a) and 5.202(i) of the Commission‘s Rules, 47
C.F.R. Sections 5.56, 5.57(a) and 5.202(i), Teligent, Inc. and its wholly—owned
subsidiaries Teligent License Company I, L.L.C. and Teligent License Company II,
L.L.C. (collectively "Teligent"), hereby request an additional Special Temporary
Authority ("STA") to operate non—type accepted equipment in the 24 GHz Digital
Electronic Message Service ("DEMS") band for six months. Teligent‘s current STA to
conduct the type of experimental testing requested in this application will expire on June
9, 1999.‘ Grant of this request is consistent with the Commission‘s March 14, 1997,
order that required: (1) the relocation of 18 GHz DEMS band to satisfy national security
requirements; (2) the discontinuance of 18 GHz DEMS operations in the Washington,
D.C. market and Denver, Colorado areas as of June 5, 1997; and (3) the discontinuance
of 18 GHz DEMS operations in all other areas by January 1, 2001.

       Specifically, Teligent seeks an authorization for six months to continue the
following operations related to DEMS relocation in markets where it currently holds 24
GHz DEMS licenses: (1) testing of various non—type accepted equipment for the 24 GHz
DEMS band; and (ii) provision of commercial service to customers using non—type

    accepted equipment for the 24 GHz DEMS band until such equipment is type accepted.
    Grant of this STA serves the public interest by facilitating DEMS relocation to the 24
    GHz band on an expedited basis, enabling Teligent to continue providing service to
    existing customers, and to continue marketing competitive local telecommunications
    services to other potential customers using its fixed wireless 24 GHz licenses. Currently,
    Teligent is aware of only one vendor that has type accepted point—to—point equipment for
    the 24 GHz DEMS band. Therefore, grant of this STA is needed as soon as practicable to
    facilitate the continued development of radio technique, equipment, operational data and
    engineering data related to DEMS, as discussed further below.



    L.     BACKGROUND


       Teligent holds licenses to construct and operate DEMS systems in the 24 GHz
frequency band in more than 70 markets. A list of Teligent‘s DEMS licenses is attached
hereto as Exhibit 1.

       On March 14, 1997, pursuant to a request by the National Telecommunications
and Information Administration ("NTIA") to alleviate potential between DEMS
operations and U.S. government military satellite operations, the Commission adopted
the DEMS Relocation Order relocating DEMS from the 18 GHz band to the 24 GHz
band in order to accommodate these sensitive national security interests. The
Commission also adopted amended service rules for 18 GHz and 24 GHz DEMS and
directed the Wireless Telecommunications Bureau to issue modified DEMS licenses
authorizing operations in the 24 GHz band. To ensure the protection of government
satellite operations, the Commission required incumbent DEMS licensees to cease
operations using the 18 GHz band within a 150 kilometer area of the government‘s earth
station facilities in Washington, D.C. and Denver, Colorado, as of June 5, 1997, the
effective date of the Commission‘s amended DEMS rules." In all other areas, incumbent
DEMS licensees must cease operations using the 18 GHz band by January 1, 2001. The
Commission also requires coordination between DEMS systems and existing Federal
Aviation Administration ("FAA") radio navigation radar facilities in the Washington,
D.C. and Newark, New Jersey, areas until such facilities are decommissioned."


       Although one vendor has obtained type acceptance for specific types of point—to—
point DEMS equipment at 24 GHz, equipment suppliers are still in the process of
obtaining type acceptance for both point—to—point and point—to—multipoint 24 GHz DEMS
equipment. Therefore, Teligent will continue to need to use non—type accepted
equipment to provide commercial service to customers, including customers in those
areas where relocation of operations from the 18 GHz band was mandated by June 5,

point—to—point operations in these licensed areas.

    1997, until the Commission grants type acceptance for all of the 24 GHz DEMS
    equipment which Teligent intends to deploy.

    IL.    THE INSTANT REQUEST

            Teligent seeks an additional six month STA for the following operations related to
    DEMS relocation in markets where Teligent is currently licensed. First, Teligent will test
    non—type accepted equipment to determine its viability for the 24 GHz DEMS band and
    all DEMS services areas and frequencies. Second, Teligent will provide commercial
    service to customers using non—type accepted equipment for the 24 GHz DEMS band. In
    accordance with the DEMS Relocation Order, Teligent will certify coordination with the
    FAA to ensure that its use of 24 GHz equipment does not cause any harmful interference.

           In light of the extraordinary circumstances surrounding the mandatory relocation
    of DEMS from the 18 GHz band to the 24 GHz band on an expedited basis, grant of
Teligent‘s STA request is clearly warranted under section 101.31 of the Commission‘s
rules. It would be inefficient and costly for Teligent to deploy 18 GHz equipment that
will have to be removed before the end ofits useful life. Such a requirement would
impose an unnecessary financial burden on Teligent as it transitions to 24 GHz.
Moreover, in order to facilitate the transition to 24 GHz, Teligent must continue to
conduct testing of the newly designed DEMS equipment in a variety of weather
conditions and environments. In any event, it is Teligent‘s understanding that vendors
are no longer pursuing type acceptance for point—to—multipoint radios in the 18 GHz band.
Thus, Teligent‘s only option to deploy and test point—to—multipoint equipment is in the 24
GHz band.

           The need for an additional STA is particularly compelling within the 150
kilometer area around Washington, D.C. and Denver, Colorado due to the fact that the 18
GHz band may not be used in these markets. Teligent is also providing commercial
service to customers markets across the country® and requires an STA to ensure that
service to such customers can continue, using point—to—point and point—to—multipoint
equipment. Moreover, 24 GHz equipment is currently available from manufacturers for
deployment. Therefore, failure to grant this STA will prejudice the public interest which,
according to Section 5.56, 5.57(a) and 5.202(i) of the Commission‘s Rules, justifies
expedited processing of an STA request.

           The Commission recognizes the "need to move DEMS quickly and with as little
impact as possible" in the DEMS Relocation Order.° Grant of the instant STA request
serves the public interest by facilitating the continued relocation of Teligent‘s DEMS
operations to satisfy national security requirements. Specifically, the STA will enable
Teligent to continue to serve customers at 24 GHz with point—to—multipoint equipment,
rather than deploying point—to—point equipment for some interim period which will

eventually need to be replaced. Furthermore, Teligent will be able to provide continued,
or initiated new, service to its customers in the aforementioned and other markets during
the transition from the 18 GHz band to the 24 GHz band. The STA also serves the public
interest by allowing Teligent to test non—type accepted equipment in various real world
environments whether it functions properly. This testing will foster a "quick" relocation
to 24 GHz with "as little impact" to the public as possible, consistent with the
Commission‘s goals set forth in the DEMS Relocation Order.
