BushLAN

Technology

A successful wireless development requires a familiarity with information science, DSP, electromagnetism and electromagnetic wave propagation, skills in radiofrequency electronic design, digital design for DSP, measurement techniques in radiofrequency electronics and propagation, and a practical understanding of networking protocols. We are currently active in the following areas:

  • Terrain Modelling
  • Radiofrequency Electronics and Software Defined Radio
  • Radiofrequency Propagation and channel measurements
  • Signal Processing
  • Networking Protocols

Wireless Regional Area Networks

The U.S. Federal Communications Commission (FCC) is currently investigating the use of cognitive radio based wireless networks in TV white space spectrum. A new wireless standard (IEEE802.22, Wireless Regional Area Networks) is being developed to meet this demand. This decision provides BushLAN with the opportunity to deploy technology commercially.

Background

The standard of internet services in rural communities is typically much worse than that in more populated areas. This is largely because of the unwillingness of the community to focus on the real causes of the problem. The BushLAN project seeks the best solution to provide long range cost effective broadband to regional and remote areas.

The BushLAN project was started at the ANU in 2001 as an exercise in undergraduate education. The scope of the project was to cover all aspects of the Bush Internet problem including an evaluation of the physical constraints that impede long range communications, market surveys that quantify the need for such a service, a mandate to make the public aware of the problem and its solution and finally the development of a new wireless technology to address the problem. To date over 40 honours, masters and PhD students have worked on various aspects of the BushLAN project.

Collaborators

Standard Communications in Sydney have worked with us in the development of a new system to exploit the UHF TV spectrum from 520 - 820 MHz. They were partners in an linkage project grant funded by the ARC. The BushLAN project is the current holder of an apparatus license for emission on 50-52 MHz in the ACT region. We are interested in groups within the ACT that would be interested in providing test cases for a BushLAN solution.
