Introduction

The ACMA is the Australian regulator for:

Broadcasting

Internet Radiocommunications

Telecommunications


3/36

Radiocommunications regulation

Spectrum planning

Spectrum management Licensing

Interference management and investigations


4/36

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)


5/36

Spectrum management contains elements of:


6/36

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)


7/36

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)

Australian Spectrum Planning


9/36

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


10/36


Public safety needs are highly variable

Competing and varying operational drivers lead to widevariations in technical requirements, including:

Coverage

Bandwidth

Topology

Availability/criticality

Security


11/36


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


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


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


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


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)


16/36

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


17/36

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


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


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


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


21/36

800 MHz in Australia and the 850 expansion


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


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


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


34/36

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


35/36

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
