Study Notes

Frequency Reuse and Handoff

The main objective of frequency reuse in cellular networks is to increase the capacity of the system by allowing different cells to use the same frequency band.

Hard and Soft Handoff

The main difference between hard and soft handoff in cellular networks is that hard handoff involves a abrupt transfer of the mobile station from one base station to another, whereas soft handoff involves a simultaneous connection to multiple base stations.

Cell Cluster

A cell cluster is a group of cells that use the same set of frequencies, where each cell in the cluster uses a different frequency from the set.

Reuse Distance

The reuse distance refers to the minimum distance between two cells that can reuse the same frequency without interfering with each other.

Two users can typically share the same channel in a cellular network if they are at a distance of at least one reuse distance from each other.
