Signal band
Optical (Laser)
Laser communication encodes data on an infrared beam instead of radio waves. Its far shorter wavelength packs data into a tighter beam, promising data rates 10–100× higher than radio — the frontier of deep-space communication, demonstrated by DSOC on the Psyche spacecraft.
