- Investigate the history of the CSIRO Wifi patent which was recently up-held in courts in the United States. This patent covers significant aspects of the OFDM implementation which is used in modern Wifi devices, 3rd and 4th generation mobile phones, and also wired communication.
You should investigate the development of OFDM, and the CSIRO patent, and in particular, answer the following questions:
1. When was the CSIRO patent applied for and in which countries
2. When will it cease to apply? Are the dates different in different countries, and if so what are some examples of differences?
3. Which firms have agreed to license the technology from the CSIRO and how much have they agreed to pay?
4. What was the most important aspect of the CSIRO patent?
5. When was the term OFDM first used to describe this approach to wireless transmission?
6. Are other parties also credited with the invention of aspects of OFDM (and if so, who are they, and what was their contribution)?
7. Which modern wireless technologies use OFDM?
