Spectrum Management in the ACMA
Guided by the Radiocommunications Act 1992
Spectrum Management:
The technical and regulatory foundation for the efficient and effective
use of the radiofrequency spectrum
Undertaken by both governments (national spectrum management)
and spectrum users (i.e. Defence)
-

Spectrum management contains elements of:
-

Why manage the spectrum?
It is a finite resource limited by interference
Interference management Quality of Service (QoS)
Standardisation and harmonisation (ITU, ETSI, IEEE) Economies of scale owing to global harmonisation
Government and community needs (e.g. Defence, public safety)

Australian Spectrum Planning Australian Radiofrequency Spectrum Plan (ARSP)
Largely shaped by international factors
ITU/APT-harmonised frequency bands
Standardisation
Various other instruments and mechanisms (eg. RALIs,embargos, FYSO)

Public Safety Communications
Object of the Act to make adequate provision of spectrumfor agencies responsible for defence, national security, lawenforcement and provision of emergency services
ACMA must balance these needs with those of the broadercommunity
Economy wide perspective in determining where spectrumshould be allocated

Public Safety Communications
Public safety needs are highly variable
Competing and varying operational drivers lead to widevariations in technical requirements, including:
Coverage
Bandwidth
Topology
Availability/criticality
Security
-
7/29/2019 A Kerans Apco Presentation
11/36
Public Safety Communications
Demand for services and bandwidth is time-variant and non-homogenous there is no one size fits all
Flexible, reticulated, multi-band approach is essential
Analogous to hierarchical command structures
End result is voice/data where and when the operatorneeds it
This necessitates a system of systems architecture
-
7/29/2019 A Kerans Apco Presentation
12/36
System of systems Combination of building blocks
Low, medium and high bandwidth systems
Varying topologies:
Fixed
Wide area mobile
Cellular mobile
Local ad-hoc
Peer-to-peer/mesh
Varying levels of supportinginfrastructure and spectrum demand
-
7/29/2019 A Kerans Apco Presentation
13/36
Low bandwidth systems Voice and text-based data, supporting:
Mission critical voice
Tasking/dispatch
Positioning
Supported by fixed and deployable base stations (startopologies)
Relevant ACMA work
Recent review of the 400 MHz band
Proposed VHF review
-
7/29/2019 A Kerans Apco Presentation
14/36
Medium bandwidth systems Text-based and rich data services and low-medium quality
mobile video, supporting:
Detailed tasking and reporting
Database interrogation (reachback)
Graphical/sensor-aided situational awareness
Supported by fixed and deployable base stations(cellulartopologies)
Recent ACMA work:
Participation in PSMBSC
800 MHz review
-
7/29/2019 A Kerans Apco Presentation
15/36
High bandwidth systems Localised rich data and (multiple) video streams, supporting numerous
localised/mobile applications:
Incident response/command support LANs
Multi-sensor linking
Short-term, wideband video linking (eg. air surveillance) Fixed backhaul for low/medium bandwidth systems*
Fixed video/other sensor linking*
Deployable base stations or peer-to-peer/short-term fixed
Fixed infrastructure on standby (if desired)
Recent ACMA work:
4.9 GHz review
* (Using non-public safety spectrum)

400 MHz review The ACMA recently replanned the 400 MHz band, with an emphasis
on provisions for Government use
Final decision paper released in 2010
NCCGR taking a leading role in managing the implementation for
Government users
Have drafted a RALI to guide implementation
Commonwealth security agencies into 380-400 MHz

Public Safety Mobile Broadband (PSMB) ACMA member of the multi-agency PSMB Steering
Committee
Committee set up to examine how an allocation of 800 MHzspectrum could help realise a PSMB capability
Gibson Quai-AAS engaged to examine and report on:
Data demand requirements
Deployment models and costs
Required amount of spectrum
-
7/29/2019 A Kerans Apco Presentation
18/36
Public Safety Mobile Broadband (PSMB) Some baseline assumptions:
Cellular topology
LTE-based
Part of a broader Public Safety communications eco-system
Pre-requisites for an allocation of spectrum
Sufficient demand
National (all jurisdiction) commitment to deploy
Inter-jurisdiction interoperability
Spectrum to be used efficiently
-
7/29/2019 A Kerans Apco Presentation
19/36
Potential PSMB delivery models Various combinations of:
Using private, fixed infrastructure in dedicated spectrum
Using private, transportable infrastructure in dedicated
spectrum Coverage for out-of-coverage areas
Supplementary capacity for in-coverage areas
Access to commercial networks via SLA
Roaming when PSMB network not available or fully-loaded
Negotiated prioritisation of public safety traffic
-
7/29/2019 A Kerans Apco Presentation
20/36
Public Safety Mobile Broadband (PSMB) Candidate spectrum between 805-825 MHz paired with 850-
870 MHz
3GPP standardised for LTE (bands 26 and 27)
Recognised under ITU Res 646 as a PPDR band
The ACMA will not make an allocation of spectrum for:
Contingency purposes
As a substitute for infrastructure
Demand that can be met by existing provisions
The ACMA will take an economy wide perspective whenconsidering if/how much spectrum is to be set aside for PSMB

22/36
The 4.9 GHz band 4940 4990 MHz to be made available for public safety use
NOT for non-emergency purposes such use will not be authorised
Primarily for responders, however access may be granted toother entities
Under agreement from an authorised responder
For support of emergency response only
On a short term basis only
Ideal for short range, high-capacity comms
Already in use in the US COTS public safety equipment available
-
7/29/2019 A Kerans Apco Presentation
23/36
Potential applications in the 4.9 GHz band Incident RLANs/command support systems
Short-haul, high bandwidth sensor linking (eg. video)
Coverage extension/meshing in remote areas
Supplementary capacity for PSMB Particularly where there is high, locally-concentrated demand
Analogous to data-offload from commercial to home wirelessnetworks
-
7/29/2019 A Kerans Apco Presentation
24/36
4.9 GHz planning implications Already in use in the US equipment available now
Class licensed
ACMA will specify technical conditions and provisions for
access ACMA cannot dictate operational details such as:
Channel assignment for whom and for what purpose?
Prioritisation
Interoperability provisions
Public safety at national/jurisdictional level will have aplanning role

International planning
ACMA contributes to studies and planning for publicprotection and disaster relief (PPDR) comms under ITUResolution 646
This includes participation in relevant ITU working groups
(under Working Party 5A) and regional fora (AWG)
Aim of participation in these meetings is to achieve a degreeof regional/international harmonisation in Australian publicsafety bands, which lead to:
Better economies of scale for devices and hardware (PPDR-spec orotherwise)
Improved scope for interoperability
-

International planning
Res 646 recognises that PPDR uses narrowband andbroadband systems
806-824/851-869 MHz used for PPDR in Region 3
This band is NOT limited to narrowband this is a myth
One ITU recommendation contains nband channel plan in this bandfor Region 3; however-
This is not the only relevant ITU recommendation
The band is being standardised for bband by 3GPP
Administrations can choose to accommodate either, or both,within the band
WRC-12 Resolution to study PPDR bband spectrum needs

Summary
The ACMA is committed to providing the necessary spectrumto meet public safety needs
Spectrum is in high demand and limited supply
Demand growth is exponential
Improved technology and sharing/ancillary access mechanisms willmitigate supply constraints, but only partially
The ACMA must balance the spectrum needs of all sectors
In an environment of constrained spectrum availability, public
safety needs are best met through a multi-layered approach Hierarchical, multi-band system of systems
