Abstract
This paper studies the use of W band in a future high throughput satellite (HTS) system alongside the Q/V band. First the available spectrum in W band is reviewed along with the propagation effects that contribute to the signal’s degradation. Then a mathematical framework for the assessment of the global feeder link availability is presented and the design challenges of a combined Q/V+W gateway system are analysed. The advantages and disadvantages are highlighted. A preliminary assessment of the feeder link availability of a combined Q/V+W band systems is given.
