High Speed Data Communications
Our ICT-based society has an insatiable demand for bandwidth. While fibre-based links now provide most of our wired communications for fixed terminals, there’s great demand for gigabit wireless communications, either to mobile terminals or to remote areas with limited fibre infrastructure.
The provision of very high speed wireless transmission is a challenging problem due to requirements for small, low power terminals, the need to deal with frequency-selective channels and the limited availability of radio-frequency spectrum.
ITR is working on very high-speed transmission systems on a number of fronts, including the following:
Gigabit millimetre-wave wireless local area networks: At 60 GHz, more than 5 GHz of ISM bandwidth is available for short range gigabit wireless systems. ITR has been working with other partners to design and test components of these next-generation WLAN systems
Higher resolution satellite imagery demands higher speed downlinks. ITR has developed a prototype gigabit demodulator for earth-resource satellites and is assisting with the commercialisation of this product
As we run out of RF bandwidth, free space optical links offer an alternative method of realising gigabit links for satellite downlinks or terrestrial applications. Unfortunately FSO links are affected by atmospheric scintillation, in a similar fashion to fading on RF channels. ITR is applying advanced coding methods to dramatically improve the performance of FSO communications
