Ka-Band Represents the Future of Space Communications:

Imagine you're in a restaurant and it's nearly empty. You can talk to your companions, low-volume, easy and relaxed. But then more patrons start arriving and it gets more and more crowded. The noise level rises; you have to shout to be heard. There's no room to move. That's a picture of the demands on the world's communication frequency bands. Cellular phones, streaming entertainment, data communications, civil and commercial providers; they are all placing incredible strains on available spectrum bandwidth. In the electromagnetic spectrum, many NASA missions use what is referred to as S-band, and commercial businesses are putting pressure on the government to free up other bands within the electromagnetic spectrum.
