alex87 Posted August 31, 2014 Share Posted August 31, 2014 Hi. I would like to ask about applications of 70 GHz radio in different fields, except cellular comm that already known. Maybe someone can help meP.S. 70 GHz (E-band) communication system able to work with speed up to 3 Gbit/s on distance about 5 miles (8 km).

Enthalpy Posted August 31, 2014 Share Posted August 31, 2014 Hi Alex87, welcome here! I'm surprised by stiff figures about a throughput and a range. The frequency alone doesn't decide that. Generally, frequencies over 40GHz have a limited range in the atmosphere because of absorption, but would propagate in space. Then, you have all the uses where a limited range is fine: an intrusion detector, a ranging radar (to park your car), a liquid height meter... There are so many! As components are already good at such frequencies, all traditional uses of GHz are possible excepted long-range transmissions. That's a lot! Do you mean a specific band around 70GHz? The whole spectrum to 300GHz and over is already sliced among possible uses, so each band has one intent: terrestrial communications, mobile communications, amateur, Ism, radioastronomy, and so on. There: http://www.itu.int/pub/R-REG-RR contents certainly available on the Web. Link to comment Share on other sites More sharing options...
