FIGS. 5A and 5B provide an example network environment 500 showing available first and second component carriers CC₁, CC₂ associated with expected KPIs 450, 450a at a first location 430a (FIG. 5A) that are different than the expected KPIs 450, 450b at a second location 430b (FIG. 5B). In the example shown, the available first and second component carriers CC₁, CC₂ are supported for carrier aggregation by a UE 300 at the first and second locations 430a, 430b to communicate with a serving base station (e.g., eNB) 102. The eNB 102 provides a first serving cell SC₁ associated with operation on the first CC₁ and a second serving cell SC₂ associated with operation on the second CC₂. The first CC1 may include a high frequency band of 1.9 Gigahertz (GHz) while the second CC₂ may include a low frequency band ranging from about 700 megahertz (MHz) to about 800 MHz. Generally, high frequency bands are suitable for attaining high throughput so long as a line of site between the UE 300 and the eNB 102 is not obstructed and/or a distance between the UE 300 and the eNB 102 is not too far. For instance, the line of site between the UE 300 and the eNB 102 is not obstructed when the UE 300 is located at the first location 430a, but when the UE 300 moves to the second location 430b, a building 590 disposed between the UE 300 and the eNB 102 obstructs the line of sight therebetween. Low frequency bands, while providing slower data rates than high frequency bands, are capable of serving larger geographical areas and providing frequencies capable of penetrating buildings, structures, or other objects that may otherwise obstruct the line of site between UE 300 and the eNB 102.
