cell phones use low power transmitters so that the frequency can be re used.i want the clear exp regarding?

Question

how it can be so.what is the operation of low power transmitters

Answer 1

Frequency reuse is more a factor of cell coverage by the base stations than anything the phone does on its own.

The use of multiple cells and multiple sectors within cells at a given base station site allow for two things: channel and frequency reuse at a single location, and smaller RF footprints at each cell/sector. Thus, cell phones themselves do not need to blast away at higher wattages in order to be recognized.
