Abstract :
A simple model of communications capability projected for the mid-1970s is formulated. The spectral dependence of the future state of the art is examined in terms of antennas, noise, diffraction effects, etc. The model suggests that the frequency spectrum in the vicinity of 1010 Hz would allow maximum information transfer and that radio-frequency techniques may be superior to the laser.
