The frequency reuse in WCDMA RAN is one, 1. This means that all cells can use the same 5 MHz for frequency band or uplink and the same 5 MHz for downlink
One operator will probably have licenses for 3-4 of the 5 MHz carriers. In order to increase capacity of the system, the operator can choose to create Hot Spots, by adding a second 5 MHz carrier to the cell. The advantage with frequency reuse is that it increases capacity.
