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 Zinfra Audit compliant

Devices – Phase 1

• 3G • Ethernet/ADSL• ZigBee• Back-up memory• MDL

• ZigBee• 433MHz• 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

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

“RF” in 2013

“RF” in 1980 … well, in fact WWII

Data integrity comes from user supervision, not from the system

“Old RF” –vs.- NewThe primary advantage of “old RF” is that it is ultra-

low costThe 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

Fundamentals of Mission Critical Systems

Example “Old RF” Problem

Strong signal quality

Reasonable signal quality

Weak signal quality

“Old RF” - Interfering Sources

Weak signal area no longer available

Old Data Collection Paradigm

May only send receive once per day

New Data Collection Paradigm

Emails synchronise across network in close to real time
