Nowadays W band (75 - 110 GHz) is an experimental frontier since no satellite telecommunication mission has been developed and the technology at these frequencies is still poor and relatively not ready. In this framework, a preliminary useful step toward the W band exploitation in satellite telecommunications is represented by the analysis and the validation of a terrestrial link operating at these...
Recently, scientific experiments are being carried out targeted to test the suitability of W-band (70-110 GHz) for the provision of broadband satellite services. W-band is a large and almost interference-free spectrum portion. For this reason, it is theoretically possible to forecast aerospace connections able at approaching the "dream value" of Gb/s data rate. This work aims at proposing...
The development of a technology demonstration payload for experimental broadband communications at Q/V bands has been funded by the Italian Space Agency. This payload will be embarked on the Alphasat satellite for testing fixed broadband ground-satellite communication services. However, the interest in the further experimentation of aeronautical mobile satellite communication services has been recognized...
The possibility to transfer huge amount of data in a very short time via satellite is attractive both for civil (i.e. telemedicine, tele-learning) and military applications. The use of EHF frequency bands is a viable possibility to reach this objective, even if, especially for the W-band, many challenges arise. The Italian Space Agency has invested in that direction with the conviction that will bring...
Q/V band frequencies are expected to play a key role in enabling challenging and unproven broadband communications missions for a wide range of applications. In the perspective to exploit these frequencies, several satellite missions have been proposed to explore the physics of the satellite channel. The strategic importance of probing higher and higher frequencies has been recognized by the Italian...
