An Introduction to… Partnered with AGL, Alinta, Agility and Jemena Installed one of the first MDL’s & continued for 18 years Team consisting of Electrical & IT expertise High standard of service – KPI’s meet consistent high performance Service & Product Management Capability Product Roadmap with long term vision & succession plan Jemena and ZinfraAudit compliant
Devices – Phase 1 • 3G • Ethernet/ADSL • ZigBee • Back-up memory • MDL Gateway – provides external building network connection to Jemena server via internet & back-up data storage Repeater – provides internal building network for connection to MDL’s, signal repeaters and interface to wireless sensors • ZigBee • 433MHz • MDL
Proposed Devices – Phase 2 Wireless Sensor – provide wireless ZigBee based sensors for installation in new buildings or retrofit situations Junction Box – provide support for connection of wired sensors where an MDL is not present (existing installations for MDL replacement, or, new installations where wireless is not required)
Bespoke –vs.- Off-The-Shelf • Designed to meet all needs • Longer lead time due to custom R&D • High R&D cost (funded by supplier) • Future-proofing/flexibility opportunity • New, hence no case studies available • Available immediately • No R&D cost • Solution does not meet all needs • No/little control • No/minimal future proofing capabilities
Benefits • Reduction in phone costs • More efficient Service and Maintenance • Improved asset management • No Line-Rental • Improved Security • Scalable – ‘Guardian’ Network Module • Able to communicate via ZigBee or Standard RF (wireless meters) • Automated Diagnostics • Capacity to retrofit non-MDL sites Confidential
Integration with Existing Systems • ExistingData Logger System Existing Financial System
Installation Scenario 4 Old RF New RF
Installation Scenario 6 New RF New RF
“RF” in 1980 … well, in fact WWII Data integrity comes from user supervision, not from the system
“Old RF” –vs.- New • The primary advantage of “old RF” is that it is ultra-low cost • The disadvantages of “old RF” are; • One way communication only, hence, no “acks” • No/weak encryption • Prone to interference & only one channel available • No repeaters, hence, must always be in range • Point to point and star networks only Key point: people sometimes do not trust “wireless” because they are thinking of old RF technology
Example “Old RF” Problem Strong signal quality Reasonable signal quality Weak signal quality
“Old RF” - Interfering Sources Weak signal area no longer available
Why ZigBee? • Security • Repeaters • Mesh networks • Ultra-low power consumption • DSSS • Long range (can be LOS 1 – 2km+) • Network heartbeat • 2-way communications w/ “acks”

It’s 2013, “wireless” is now used for mission critical systems …
Old Data Collection Paradigm May only send receive once per day
New Data Collection Paradigm Emails synchronise across network in close to real time
