2 Scope The next generation telecommunications systems of the Battlefield Communications System (Land) BCS(L) provides the Communications and Information Systems (CIS) infrastructure to all deployed forces operating in the land environment. Defence has fielded the Enhanced Position Location Reporting System (EPLRS), and the smaller MicroLight dismounted radio system, as the next generation Tactical Data Distribution System. 11/14/ Discussion EPLRS Rollout Information on parameters to further exploit the effectiveness of this radio system Outline of planned developments Establishment of a baseline for the new communications architecture regarding the TDR network within the Battle Group and Below Command, Control and Communication (BGC3) context 11/14/

3 Radio Hardware Vehicular Receiver/Transmitter IP based device Data Rate Adjustable to 1Mbps TDMA, FDMA and CDMA Direct Sequence Spread Spectrum Frequency hopping BLOS via Automatic Relaying Embedded Security Embedded Time of Flight Position Location Mhz (XF Mhz) MicroLight Man-Portable Receiver/Transmitter 11/14/ EPLRS Software EPLRS Network Planner (ENP) Required to Construct EPLRS Communications Plans EPLRS Network Manager (ENM) Runs on Standard Pentium Windows Laptop Required for Initial Plan Deployment Not Required for Ongoing Network Operation Required for Crypto and Radio Updates 11/14/

4 Communications Technology Multiple access modes Contention access multiple broadcast Dedicated access multiple broadcast Point to point permanent / switched virtual circuit Bandwidth allocated on demand Position Determination Radios determine own location via time of flight, barometric pressure sensor and from a percentage of GPS or geo-referenced radios within the network Net Management Radios can be configured in real time 11/14/ Multi-Hop Networking Relay chains are self forming, self healing Automatic adaptation to dynamic RF environment Multicast relaying without self-jamming (mutual interference) 11/14/

5 Time of Flight Radios automatically measure time of flight from next hop radios Time of flight converted to distance measurement Multiple distance measurements used to compute relative location Referenced Node Un-located Node Located Node Time of Flight Position Location Time of Flight Positioning Operates in GPS Denied Environments 11/14/ Rollout Approximately 1500 RT-1915 (Vehicle) and 440 RT-1922 (Dismount) purchased under JP2072 Ph 1 Majority of assets within 7BDE, 1 BDE 3 BDE Deployed on HAMEL 2012 and Talisman Sabre 2013 Predominantly BMS Fires Battlefield Command and Support System (BCSS) Support: Australia Field Support Representatives Engineering Technical Repair US Engineering Modelling and Simulation 11/14/

6 Current Baseline EPLRS network Single Mobile Ad-Hoc Network (MANET) Suited to multicast traffic profiles 2-hop neighbourhood, OSI Layer 3 functionality allows for frequency and timeslot re-use Bandwidth dynamically allocated based on need within neighbourhood Guaranteed contention-free transmissions on Fair and Priority slots Each radio constantly calculates which specific radio wins each slot Single Channel Allocated Multiple Channels available Supporting Army-HQs, ADF Plan IP Addressing Schema Naming conventions Unit Reference Number (URN) 11/14/ Planned Developments EPLRS is a software programmable radio Radio software upgrades generally released twice per year Software updates include enhancements and anomaly fixes driven by customer and the OEM Relative to current firmware the latest release includes: Multicast improvements Updates to the multicast relay algorithms to increase multicast message completion rate Relay selection based on link quality Duplicate multicast packet error detection Tailor MANET to increase available bandwidth configurable by ENM Max unicast relay hops Max multicast relay hops All these enhancements increase EPLRS scalability 11/14/

7 Future Enhancements Connectivity to digital trunk Multiple connection points Multicast Improvements Improved relay selection Enhanced Routing Reduces operator programming of edge router 11/14/ Baseline for new Communications Architecture Focus is on ability to scale Additional functionality provided by recent firmware release Stacked MANET networks Frequency separated Interlinked Primarily Multicast traffic Nodes can be managed by an ENM from anywhere on the network Tuned to the Battle Management System, BGC3 11/14/
