File No. SES-LIC-20070409-00466
Dear Ms. Birkelbach:
On April 9, 2007, MCI Communications Services, Inc. FKA MCI WorldCom 
Communications, Inc. (MCI) filed the above-captioned application seeking an earth station
license to operate a VSAT Network in the extended and conventional Ku-bands.1  
Section 25.112 of the Commission’s rules, 47 C.F.R. § 25.112, requires the Commission 
to return, as unacceptable for filing, any earth station application that is not substantially 
complete, that contains internal inconsistencies, or that does not substantially comply with the 
Commission’s rules. MCI’s application contains several omissions and discrepancies that render 
it unacceptable and subject to dismissal.  These deficiencies are as follows:
Pursuant to the U.S. Table of Frequency Allocations, 47 C.F.R. § 2.106, use of the 12.2-
12.7 GHz band is limited to the Broadcast Satellite Service.  In its application, MCI does not 
propose to provide Broadcast Satellite Service.  Further, MCI indicates that its earth station will 
receive in the 12.7-12.75 GHz band.  The Table of Frequency Allocations designates this band for 
uplink transmissions only.  MCI does not request a waiver of the Table of Frequency Allocations 
to permit its proposed non-conforming uses.
In addition, the 10.95-11.7 and 12.2-12.75 GHz bands are shared on a co-primary basis 
with the Fixed Service.  Section 25.203(c) of the Commission’s rules, 47 C.F.R. § 25.203(c),
requires earth station applicants seeking authority to use these bands to include a Frequency 
Coordination Report with respect to Fixed Service operations.  In response to Question E18 of 
Schedule B, however, MCI incorrectly states that frequency coordination is not required and did 
not submit a Coordination Report.  
Finally, in Schedule B of the license application, MCI indicates that the only Points of 
Communication for the proposed earth station are ALSAT-designated satellites.  Only those 
fixed-satellite service earth stations that are both two-degree compliant and operate in the 3700-
  
1 10950-11700, 11700-12200, 12200-12750, and 14000-14500 MHz bands.

4200 MHz, 5925-6425 MHz, 11.7-12.2 GHz, or 14.0-14.5 GHz bands can request ALSAT as a 
point of communication.  Because MCI proposes operations in the 10.95-11.7 and 12.2-12.75 
GHz bands, the application must identify the specific satellite or satellites with which the 
proposed earth station seeks to communicate in these bands.2  
Accordingly, pursuant to Section 25.112(a)(1) of the Commission’s rules, 47 C.F.R. 
§25.112(a)(1), and Section 0.261 of the Commission’s rules on delegations of authority, 47
C.F.R. §0.261, we dismiss the application without prejudice to refiling.3
Sincerely,
Scott A. Kotler

Provide Domestic and International Services in the United States, First Order on Reconsideration, IB 
Docket No. 96-111, 15 FCC Rcd 7207, 7214-16 (paras. 16-20).

corrected information, it need not pay an application fee.  See 47 C.F.R. § 1.1109(d).
