Typo: It could be defined, for a two way data transmission system, as repeated meaningful transmission of data x over distance d, and return in average time t of transmission t of a meaningful response message f(x), as v = t/(2d). Correction: It could be defined, for a two way data transmission system, as repeated meaningful transmission of data x_i over distance d, and return in average time t of a meaningful response message f(x_i), as v = t/(2d).
