T-Mobile Licensee LLC
Request for Part 5 Experimental
Special Temporary Authority
ELS File No. 0709-EX-ST-2017

NARRATIVE STATEMENT

Pursuant to Sections 5.3 (j) and Section 5.61 of the Commission’s rules, 47
C.F.R. §§ 5.3(j), 5.61 (2016), T-Mobile Licensee LLC (“T-Mobile”) hereby
respectfully requests experimental special temporary authority (“STA”) from
May 10 to November 10, 2018, to evaluate the technical performance of pre-
production License Assisted Access (“LAA”) equipment. The experiments will
operate in AWS-1 spectrum licensed to T-Mobile as well as in unlicensed 5 GHz
spectrum (in a downlink-only mode). As T-Mobile is the licensee for the AWS-1
spectrum, experimental authority is only needed for the 5 GHz spectrum. The
testing will be in a highly controlled field environment that will help T-Mobile to
allow the pre-commercial testing of new products outside of a lab environment
but in a controlled and managed manner.

A. Purpose of Operation and Need for STA:

T-Mobile is working with equipment vendors to conduct product testing of new
LAA equipment. The trials at the various locations listed below will allow
T-Mobile to test pre-production equipment in outdoor and indoor setting prior to
equipment certification. The trials will consist of up to 10 small cells and access
points that will use the transmission parameters detailed below in Section C.
Mobile units will operate within the RF coverage area of the small cell stations.
The mobiles will be receive-only in the unlicensed 5 GHz band but will also
include an LTE transmitter that will operate in the AWS-1 spectrum. T-Mobile
anticipates using as many as 10 mobile units at each location.

B. Location of Proposed Operation:

T-Mobile intends to conduct testing within 5 kilometers of the 10 locations with
the address and approximate reference coordinates (in Datum: NAD83) of each
of the fixed locations:

C. Technical Specifications:

1. Frequencies Desired

T-Mobile will be using AWS-1 spectrum for the testing as well as
unlicensed 5 GHz spectrum. Specifically, T-Mobile will be transmitting
in accordance with the table below:

Device Transmit ERP ERP Emissions Technology
Type Frequency Band (W) (dBm) Designator
(MHz)
Small cell and 5150-5250 2.4 33.83 60M0W7D LAA
Access Point
Small cell and 5725-5850 2.4 33.83 60M0W7D LAA
Access Point
Mobile 5150-5250 0.3 24.83 60M0W7D LAA
5725-5850

2. Equipment To Be Used

T-Mobile will be using prototype equipment that has not yet received
FCC certification. This equipment will be provided by a number of
vendors.

D. Protection Against Causing Interference:

T-Mobile is requesting use of the unlicensed 5 GHz spectrum bands. T-Mobile
understands that it must accept any interference from any users of this band and
that all operations by T-Mobile will be on a secondary basis. T-Mobile has
established a point of contact identified below with “kill switch” authority should
any interference occur to primary licensed services. Should interference occur,
T-Mobile will take immediate steps to resolve the interference, including, if
necessary, arranging for the discontinuance of operation.

E. Restrictions on Operation:

T-Mobile is not seeking authority to perform a market study under the requested
STA. Moreover, no fees will be charged to entities using the equipment during
this test. Entities will be advised in accordance with Section 2.803 of the
Commission’s rules, 47 C.F.R. §2.803, that any unapproved devices which have
not been authorized as required by the FCC are not being offered for sale or
lease, or sold or leased, until authorization is obtained.

F. Public Interest:

2

T-Mobile submits that issuance of the STA as requested is in the public interest,
convenience, and necessity. Grant of an STA will help T-Mobile to develop and
test innovative equipment to provide service to consumers.
