Verizon 3.5 GHz Experiment Proposal

1. Introduction
Verizon Communications Inc. (Verizon or the Company) is a holding company that, acting
through its subsidiaries, is one of the world’s leading providers of communications, information
and entertainment products and services to consumers, businesses and governmental
agencies. With a presence around the world, we offer voice, data and video services and
solutions on our wireless and wireline networks that are designed to meet customers’ demand
for mobility, reliable network connectivity, security and control. We have two reportable
segments, Wireless and Wireline. Our wireless business, operating as Verizon Wireless,
provides voice and data services and equipment sales across the United States (U.S.) using
one of the most extensive and reliable wireless networks.

2. Experiment Description
Verizon is working with partner companies to develop equipment that will use LTE technologies,
using Citizens Band Radio Service (CBRS) spectrum, also known as Band 48, using 3GPP
terminology. As part of the technology validation, Verizon plans to conduct a series of field tests
with Category B Citizen Band Service Devices (CBSDs) at one or more locations, restricted to
the frequency range 3650 MHz – 3700 MHz (i.e. the upper 50 MHz of the CBRS band)

The purpose of the proposed tests is:

1) Evaluation of the radio propagation characteristics of 3.5 GHz for outdoor installations
2) Evaluation of end-to-end CBRS architecture
3) Evaluation of TDD-LTE using 3.5 GHz
4) Evaluation of inter-band carrier aggregation between 3.5 GHz and licensed bands using
3GPP Band 2, Band 4, Band 66 or Band 13 (Verizon’s legacy licensed bands)

Field tests will be conducted in a trial network, closely resembling a production network, in a
highly controlled field environment, in order to assist in the development of commercial
products. The testing will benefit the public interest by enabling the pre-commercial testing of
new products outside of a lab environment but in a controlled and managed manner.

This field trial will consist of an aggregate of no more than ten (10) Category B CBSDs, for all
the trial locations. The CBSDs will use the transmission parameters and operate inside the
geographic regions defined below. Some of the tests will use solely base stations and user
equipment operating in CBRS spectrum only. Some equipment however, includes 3GPP LTE
base stations that operate on 3GPP Band 2, Band 4, Band 66 or Band 13, also known
respectively as the US 1900 MHz PCS, AWS bands and 700 MHz operated under 47 CFR Part
24 and Part 27. Transmission on PCS, AWS or 700 MHz spectrum will occur using VZ’s legacy
licensed spectrum.

Mobile devices will also operate within the RF coverage area of the small cell devices. Some of
the tests with mobile stations will be using CBRS spectrum only. The majority of the tests,
however, will include mobiles and base stations with LTE transmitters that operate on 3GPP
Band 2, Band 4, Band 66 or Band 13, in carrier aggregation mode (in both Downlink and Uplink)
with Band 48.

Although the initial devices are prototypes and have not completed formal equipment
authorization, the equipment used in these trials will be compliant with FCC rules. As time
progresses, pre-commercial devices will be introduced. Equipment from multiple equipment
manufacturers will be used in the evaluation testing. Verizon has the ability to shut down all
transmissions operated under the experimental license in the unlikely event any interference
occurs.

3. Hours of operation and equipment shut down
The intent is to operate the evaluation devices, both small cells and mobile units, 24 hours per
day, 7 days per week, during the test period. Equipment can be shut down speedily, if the need
arises, by contacting one or more of the interference coordinators identified in the section
“Interference Coordination”

4. Interference Coordination
Immediate requests to stop transmissions under this STA can be communicated to Sergio
Aguirre, Verizon Network Planning at 682-831-6060 or by email at
sergio.aguirre@verizonwireless.com or Wai Shun Wilson Wong, Verizon Network Planning at
(925) 279-6847 or by email at waishun.wong@verizonwireless.com

5. Trial Duration
Approximately one year, beginning in September 2019.

6. Evaluation Equipment Transmitter Information
Small cells supporting a subset (3650-3700 MHz) of Band 48 will be operating in compliance
with FCC Part 96 rules. Directional antennas will be used with the small cell systems within the
maximum EIRP and antenna gain constraints as specified in the FCC rules.

LTE mobile devices support LTE-TDD operation with an LTE uplink in Band 48 (3650 – 3700
MHz) and receive in the same band. Upon availability of mobile devices supporting inter-band
carrier aggregation, CBSD devices supporting one or more of Verizon’s licensed bands will be
used.

• Up to ten (10) Category B CBSDs (EIRP ≤ 50 dBm/20 MHz using Band 48
• Multiple mobile terminals (approximately up to 10 mobile terminals) operating in Carrier
Aggregation (CA) mode, using licensed bands B2, B4, B66 or B13 or a subset of these,
in CA aggregation with B48, using LTE(FDD/TDD), with a maximum transmitter EIRP =
24 dBm

For outdoor Category B CBSD radio installations, integrated antenna as well as directional
antenna with horizontal orientation ranging from 36-degree to 360-degree in step of 36-deg (i.e.
36°, 72°, 108°, 144°, 180°, 185°, 216°, 252°, 288°, 324°, 360°) will also be evaluated for
transmission and reception.
