Dear Dr. Schoene,
Approval is hereby granted for LStelcom AG (LStelcom) to operate its “TV bands database system” to 
provide service to the public.  This database system will provide support to unlicensed radio devices that 
transmit on unused channels in the spectrum bands used by broadcast television (TV white spaces, or 
TVWS).
The Commission’s Part 15 rules (47 C.F.R. § 15.701 et seq.) require that unlicensed radio transmitting 
devices that operate in the broadcast television bands contact an authorized database system to obtain a 
list of channels that are available for their operation (i.e., channels not occupied by authorized radio 
services) at their individual locations and operate only on those channels.  These devices are required to 
provide their geographic location, by means of a secure Internet connection, to a TV bands database 
system authorized by the Commission.  The database will then return a list of the channels available for 
operation by the device for its reported location.  
LStelcom, along with a number of other entities, was conditionally designated as a TV bands database 
administrator under the Part 15 rules in an Order issued by the Commission on January 26, 2011, 26 FCC 
Rcd 12827 (2011).  Final approval for each designated database administrator’s operation of a TV bands 
database system was subject to compliance with requirements that it: 1) supplement its previous filings 
with sufficient information to demonstrate how it will comply with the rule changes adopted in the 
Second Memorandum Opinion and Order (ET Docket No. 04-186, 25 FCC Rcd 18661 (2010)); 2) agree 
that it will not use its capacity as a database manager to engage in any discriminatory or anti-competitive 
practices or any practices that may compromise the privacy of users; 3) coordinate closely with the 
agency to ensure competency, consistency, and compliance with the rules; 4) participate in a series of 
mandatory workshops conducted by the Commission’s Office of Engineering and Technology (OET) to 
address implementation issues and to ensure consistency and compliance with the rules; and 5) subject its 
database to real-world testing for a period of not less than 45 days.  This public trial is intended to allow 
interested parties an opportunity to check that the database provides accurate results before being made 
available for actual use by TV bands devices.
LStelcom has provided the required submissions and has participated in the workshops in compliance 
with conditions 1 through 4.  In addition, it conducted a public trial of its database system as required by 
condition 5 from June 24, 2013 to August 8, 2013, Public Notice released June 18, 2013, DA 13-1401.  In 
this trial, LStelcom made its channel availability calculator, as well as its procedures for registering 
protected facilities, including low power auxiliary services (principally licensed and unlicensed wireless 
microphones), MVPD receive sites, and temporary broadcast auxiliary links that are not in the FCC 
2databases available for testing by the public.  During the trial LStelcom received and satisfactorily 
resolved several comments and concerns regarding the performance of its database system.  Actions taken 
in response this feedback from the public included several changes to improve the functioning of the 
database system.  LStelcom’s final report on its 45-day public trial was placed in the record of the TV 
white spaces proceeding, ET Docket No. 04-186, and comments were requested in a Public Notice 
(Public Notice) released November 14, 2013, DA 13-2182. 
No comments were received regarding LStelcom’s final report or other aspects of the trial.  Given that 
many parties examined the LStelcom database system during its public trial, we find the absence of 
comments on the data base content, channel availability calculator and registration features to be 
indicative that the system is now satisfactory in those areas.
Based on our own examination and testing of the LStelcom database system, the results of the public trial, 
including comments submitted to LStelcom during the trial and LStelcom’s responses to those comments, 
and the fact that no comments expressing concerns were submitted in response to the Public Notice on 
LStelcom’s final report, we find that LStelcom has demonstrated that its channel availability calculator is 
able to properly determine the unused channels at a location that may be used by the different types of 
unlicensed TV bands devices.  We also find that its registration procedures properly record, store and 
retrieve protected facilities that are not in the FCC databases.  In addition, we find that the LStelcom 
database system properly synchronizes registration records with the TV bands databases of Spectrum 
Bridge, Inc., iconectiv (formerly Telcordia Technologies, Inc.), Google, Inc. and Key Bridge Global LLC
using the White Space Database Administrator Group’s Database-to-Database Synchronization 
Interoperability Specification, Version 1.01 September 12, 2011.  We therefore find that LStelcom’s TV 
bands database system is compliant with the Commission’s rules for TV bands database systems and 
ready for operation. We have not yet tested this database system with an actual TV bands device.  When 
an application for a TV bands device that accesses LStelcom’s database system is processed, we will 
verify that the database’s provisions for securing communications between a device and the database are 
functioning in accordance with the rules in conjunction with our testing of the device itself.
As the implementation of the Commission’s plan for operation of TV bands devices proceeds, we 
anticipate that there may be additional changes, generally minor, in various aspects of the plan.  There 
may also be elements of LStelcom’s database system that will need to be adjusted as experience is gained 
with TV white spaces operations by the Commission, the database administrators, device manufacturers, 
and device users.  We will provide instructions to LStelcom and the other database administrators to 
incorporate and test refinements at such time as they may be developed.  We do not generally expect that 
such refinements will necessitate additional testing through a public trial.  We anticipate that operation of 
these features will be verified by the OET staff.  Nonetheless, we are reserving the option to request that 
LStelcom undertake additional public trial testing if we determine that such testing is necessary to ensure 
that the database systems properly determine available channels and protect authorized services.  
However, it is also possible that the Commission could adopt major changes to the rules for TV bands 
devices.  Depending on the nature of such changes, the Commission could also require that the 
operational TV bands databases undergo additional testing and public trial to ensure that they comply 
with those changes.
3Accordingly, we are granting approval for LStelcom AG to operate its database system to provide service 
to certified unlicensed devices that operate in the broadcast television bands as described above.  
Authority for this action is provided in Section 0.241(h) and Sections 15.701-.715 of the Commission’s 
rules, 47 C.F.R. § 0.241(h) and §§ 15.701-.715 and Sections 4, 5, 303, 304, 307, 336, and 554a of the 
Communications Act of 1934 as amended, 47 U.S.C. Secs. 154, 155, 302a, 303, 304, 307, 336, and 624a.
Sincerely,
Julius P. Knapp
