Mr Graham Daniels.

Mr Graham Daniels completed a Bachelor of Science (physics, pure mathematics) in 1970 and a Bachelor of Electronics with first class honours in 1972 at the University of Sydney, New South Wales, Australia.

He began his career as a Research Assistant to Dr Robert (Bob) Frater (then Senior Electronics Lecturer) at the University of Sydney, School of Electrical Engineering.

He worked mainly on the commissioning of the first (analogue correlator) version of the Fleurs Synthesis Telescope, in which an area of particular interest was analogue circuit design.

From 1974–91, he worked as a Senior Design Engineer and System Architect for Summit Electronic Systems and Summit Communications on data communications, security, and industrial control products based on embedded microprocessors.

Many of these products were intended for remote or unattended operation, so an area of particular significance was resistance to transient faults and to hardware/software tampering.

In December 1991, he joined the 'PLANS' group at the CSIRO Division of Radiophysics (now the ICT Centre) following informal discussions with Drs Bob Frater and John O'Sullivan to work on the development of high data rate wireless LAN technology.

This work proceeded for several years and extended into low-level communications protocols, ad hoc network architectures, communications resource management, communications system security and reliability.

More recently it has included multi-dimensional (space-time, cellular etc.) wireless communication techniques. He is currently a Senior Principal Research Scientist with CSIRO's ICT Centre working on communications protocols and ad-hoc network architectures.

Following on from the initial WLAN work, Mr Daniels worked on:

  • MIMO systems using single and multi-carrier modulation
  • low-rate ELF through-rock (cellular) emergency mine communications (Pat. US 7043195)
  • reliable, tamper-resistant sensor-actuator networks for array blast initiation
  • underwater acoustic communications networks
  • broadband galvanic isolators for coaxial RF transmission lines.

Currently, Mr Daniels is working on the development of Intrinsically Safe, a through-rock, emergency communication systems for underground (coal) mines. This work (through CSIRO) is an extension of earlier CSIRO investigations, and is for an Australian company.
