Frequency Reuse
Frequency reusing is
the concept of using the same radio frequencies within a given area, that are
separated by considerable distance, with minimal interference, to establish
communication.
Frequency reuse
offers the following benefits −
- Allows communications within
cell on a given frequency
- Limits escaping power to
adjacent cells
- Allows re-use of frequencies
in nearby cells
- Uses same frequency for
multiple conversations
- 10 to 50 frequencies per cell
For example,
when N cells are using the same number of frequencies
and K be the total number of frequencies used in systems. Then
each cell frequency is calculated by using the formulae K/N.
In Advanced Mobile
Phone Services (AMPS) when K = 395 and N = 7, then frequencies per cell on an
average will be 395/7 = 56. Here, cell frequency is 56.
