Shadows of the future in vehicular communication

This paper constitutes a discussion of certain changes in vehicular communication services and equipment that may be expected in the not too remote future. These changes are related, not only to technology, but also to the problems created by the slow but sure depletion of the available radio frequency spectrum space. Attention is directed to the great potential that exists for better utilization of the spectrum through improvements in the space (or volume) and time dimensions. It is pointed out that the effective use of air time through automation of routine or repetitive type communications promises to give, in effect, a many-fold increase in the available spectrum.
