| Micro Cells |
In large cities, mobile phone operators are increasingly
converting their networks to small cell structures (cells).
Larger mobile phone cells with diameters from 10 to 20 miles
are "macro cells". Radio cells in the mid- range (with a diameter
of about one mile) are "micro cells". Even smaller are pico
cells, which often only range a few hundred meters. The miniaturization
of radio cells allows more subscribers to be supplied over a
given area. |
