Spectrum Management
Overview
• The primary focus of spectrum management is to obtain an
approved frequency license from the controlling authority at
the international, national, host nation, unified command,
allied, or military department-level.
• Spectrum management is the planning, coordinating, and
managing the use of the electromagnetic spectrum through
operational, engineering, and administrative procedures
• The goal of spectrum management is to enable electronic
systems to perform their functions in the intended environment
without causing or experiencing unacceptable interference.

12-Step Lifecycle
4 Major Deliverables
Some activities
are conducted
simultaneously;
others are
completed in
succession.
UNCLASSIFIED
UNCLASSIFIED
Step 1: Define Policy
• Reading and understanding existing policies/guidance and
modifying, if necessary for mission
• Deliverables include:
 JTF spectrum management concept
 Spectrum requirements data call message
UNCLASSIFIED
UNCLASSIFIED
Step 2: Gather Requirements
• Capturing and documenting spectrum requirements of all
spectrum users (includes comm, non-comm, and “receive
only” systems)
• Satellite Access Requests / Authorizations (SAR/SAA)
authorizations for UHF / SHF / EHF satellite use
• Capturing undocumented requirements from sources external
to spectrum management coordination
UNCLASSIFIED
UNCLASSIFIED
Step 3: Develop Spectrum
Requirements Summary
• Compilation of requirements identified from data call
• Can be used to quantify necessary spectrum, determine
frequency sharing and reuse needs, help in developing
allotment plans
• Tool for Spectrum Manager to make decisions on efficient
spectrum use and requirements definition
UNCLASSIFIED
UNCLASSIFIED
Step 4: Define Electromagnetic
Battlespace
• Common, single, authoritative source for spectrum-use
information for all friendly, enemy (to extent available), neutral,
and civil emitters and receivers
• Common spectrum-use database
• Identifies factors effecting signal
propagation (e.g., environmental
characteristics and terrain)
• Ongoing activity
UNCLASSIFIED
UNCLASSIFIED
Step 5: Obtain Spectrum
Resources
• Requested from host nations unless forced entry
• Previous activities and evaluating EME help determine amount
of spectrum needed

• Resources created and stored
as allotment plans

Step 6: Develop SM Plan
• Establishes JTF specific guidance for managing, requesting,
coordinating, and assigning spectrum use; JRFL, JCEOI, and
other processes
• Documents how to address interference problems, reporting,
and resolution steps
• Becomes SM appendices to Annex K of OPORD
• Depends on products from previous activities
• Evaluated continuously
UNCLASSIFIED
UNCLASSIFIED
Step 7: Nominate and Assign
Frequencies
• Implements the spectrum management plan
Database Only
Spectrum XXI Infrastructure
• Initial assignment of frequencies (may be
delegated)

Step 8: Generate JCEOI
Two part document:
• Part 1 – directory of frequencies, call signs,
call words, and net IDs listed by time period
• Part 2 – supplemental procedures for
electronic, visual, and verbal interactions
(sign/countersign, smoke/pyrotechnics,
suffix/expanders)
• Responsibility of the J-6; normally
delegated to JSME/JEMSO
UNCLASSIFIED
UNCLASSIFIED
Step 9: Develop JRFL
• Time- and geographical-oriented list of functions, nets, and
frequencies requiring protection from friendly EW
• Protects JTF C2 comm nets, enemy comm nets being
exploited, and JTF and civil noncombatant’s safety-of-life
frequencies
• Consolidated effort among JTF
staff organizations and functional/
Service components
UNCLASSIFIED
UNCLASSIFIED
Step 10: Perform EW Deconfliction
• Supports EW activities
• Provides IO cell with
analysis of potential impact of friendly EW operations on
friendly forces
• EWCC decides if benefits of jamming mission outweigh
dangers. This capability has historically been underutilized.
• Time sensitive and produced as needed
UNCLASSIFIED
UNCLASSIFIED
Step 11: Resolve Interference
• Daily activity once deployed; not part of planning process
• Includes interference analysis and attempts to resolve
• Uses EMB to determine if problem was overlooked or
miscalculated
UNCLASSIFIED
UNCLASSIFIED
Step 12: Interference Reporting
• Interference always a reality; too many emitters to preclude all
interference
• Documents results of interference
analysis
• Reports maintained in a database
for historical record (JSIR O)
• Includes ongoing maintenance of
the database until JTF is dissolved
UNCLASSIFIED
UNCLASSIFIED
Spectrum
Management Tools
• Systems Planning Engineering and Evaluation Device (SPEED) is a software
program for communications planning and. SPEED provides a standard set of
software components to perform RF link analysis and engineering, spectrum
management, and interference & deconfliction
• Afloat Electromagnetic Spectrum Operations Program (AESOP) is an integrated
operational radar, combat system, and communications frequency planning tool
• Joint Communications Electronic Operating Instructions Automated
Communications Software (JACS) is a software used to generate JCEOI’s and
deconfliction frequencies based on assignments obtained via SPECTRUM XXI. This
software produces a phonebook like document for frequencies
• SPECTRUM XXI is a client/server, Windows-based software system that provides
Frequency Managers with a single information system that supports operational
planning, assigning compatible frequencies, and performing Spectrum engineering
tasks
UNCLASSIFIED
UNCLASSIFIED
Spectrum
Management Tools
• Host Nation Spectrum Worldwide Database (HNSWDO)
– https://hnswdo.jsc.mil/Introductory.aspx
– Web application providing worldwide visibility of host nation RF spectrum
dependent equipment's supportability.
– Automates distribution of host nation coordination requests and combatant
command submission of host nation supportability comments.
– Available on unclassified and classified network.
• Joint Spectrum Data Repository (JSDR)
– Contains DoD, national, and international spectrum-related information up to
the Secret level and can be accessed via the JSC Data Access Web Server
(JDAWS) tool
– features the following spectrum-related databases: Joint Equipment, Tactical
and Space (JETS), HNSWDO, Spectrum Certification System (SCS) Database,
Background Environmental Information (BEI), Government Master File (GMF),
Frequency Resource Record System (FRRS), Area Studies
• JSC Data Access Web Server (JDAWS)
– Provides user access to the database components of JSDR except Equipment
Location-Certification Information Database (EL-CID)
UNCLASSIFIED
UNCLASSIFIED
Spectrum Management Tools
Spectrum Situational Awareness Systems (S2AS)
• S2AS is comprised of a hardware component (Rohde & Schwarz PR100 receiver) to
collect the spectrum and a software component (Multi-spectral Ambient Noise
Collection and Analysis Tool - MANCAT) used to analyze the collection.
• Provides the ability to take a real time snapshot of the electromagnetic environment
and compare the database records against the actual spectrum picture.
• The spectrum manager can analyze the collected spectrum for compliance with the
static database, locate rogue signals, direction find on signal transmitters, and
resolve frequency interference.

– Mercury
Spectrum Management Tools
• Mercury was developed to coordinate spectrum used with host
nations.
• http://mercury.dreamhammer.com/app/
• Mercury is a spectrum coordination application - NOT a
spectrum management tool but it has some basic spectrum
management functions.
• Mercury allows users to request and receive frequency
assignments via an unclassified web-based environment.
• Builds Databases that are both PUB 7 and PUB 8 compliant.
• Cloud-based application accessible by any web browser.
• Simplified frequency request form for ease of use by nonspectrum managers
– Contains text messaging, drop-down menus, limited help
features and auto and pre-populate features.
• Language translation feature for cross-border coordination

architecture.
• EW tool to check the affect of a jammer on assigned
frequencies.
• JRFL now able to be published and shared with all SXXI

What’s Expected from
a Spectrum Manager
• SME for the Commander on spectrum related issues. The Spectrum
manager advises the commander on the pros and cons when issues
surface.
• Technically proficient or familiar with spectrum management tools, policies
and regulations, and equipment required to perform Spectrum
Management tasks.
• Top Secret Clearance is desired. This allows spectrum managers to
understand the EW and Intel requirements which often are not captured
through routine activities.
• Able to articulate requirements needed to accomplish any given units
mission while using spectrum efficiently.
• Enable the CDR to make decisions based on JEMSO Cell inputs for
spectrum related issues.
