I think it was the digital side (packet switching etc.) of things that
the US military and others were playing with in more recent times. The
basic cellular concept (sans automatic switching) as described in e.g.
:-http://en.wikipedia.org/wiki/Cellular_network
involves earlier zoned use by taxi firms in populated areas as a means
of re-using the same frequency on a relatively local basis by
providing sufficient distance from the nearest adjacent zones/cells
using the same frequencies but has no reference to military use.

The following is the BSTJ issue on cellular.

A search of "mobile" on the BSTJ site produces many articles over the
years. Things like "An Extended Correlation Function of Two Random
Variables Applied to Mobile Radio Transmission", and "Frequency-Hopped
Single-Sideband Modulation for Mobile Radio", and "Frequency Economy
in Mobile Radio Bands"
