E 'already been received with great enthusiasm the news of the launch of the satellite fully dedicated to internet KaSat. Eutelsat, the company that manages the European satellites, launched from the Baykonur polygon, in Kazhakstan, at the end of 2010.
In many see the end of the digital divide, but we believe that improving the ' terrestrial cable infrastructure would be easier, safer and less expensive . Meanwhile, we know, the technology race is too seductive, and the main news point out that this satellite will be in Europe earlier than in the U.S. (sad record for us in the U.S. have cable television for several years and were quite clever by costruistri better infrastructure!)
This signal will cover most of this satellite, bombing our heads with electromagnetic waves at frequencies of 20-30 GHz. Recall that it is dangerous to use such high frequencies. Indeed the higher the frequency , most electromagnetic waves interact with matter and then with our own flesh. Moreover, since these reports must cover large distances (one satellite will cover all of Europe) and the Internet traffic is usually very high, even the ' intensity of this radiation will be very high ! But, in our opinion, the most dangerous thing is that usifruire of this traffic must adopt a set-top box with an antenna that can send at 20-30 GHz signal to the satellite, so let's say an antenna powerful and polluting. And since this satellite will provide not only in high speed upload download, but also, there are strong limitations in the emissions.
The subscription price for the end user starts it is estimated that between 30 and 35 € more expensive then that of an ADSL classic. It is not clear so why should not we ask and fight for a DSL cable.
