What is "Fiber Optic Microcellular"?

Question

It is a current research area in optical fiber communications, but I don't have an idea what it is about.

Answer 1

The link in the source gives a short description of one potential application:

"We consider a urban fiber-optic microcellular environment in which a cigar-shaped cell consists of several microzones with their own antenna sites connected to a central station through optical fibers. To increase the efficiency of radio resources and to reduce unnecessary handoff calls between microzones, we propose a movable safety zone scheme in which each communicating user has his own safety zone not permitting cochannel reuse. His safety zone also can move if his cochannel interference is not met as he moves to an adjacent microzone."

It sounds as if it is basically a way of dividing cells up into smaller regions so that lower power transmissions can be used, while increasing the total available bandwidth within the main cell without requiring the use of any additional parts of the spectrum.
