Glossary Definition for: Carrier Aggregation

One of the biggest challenges facing mobile network operators is that they have lots of 5MHz and 10MHz bandwidth chunks of spectrum, but to offer the fastest possible speeds LTE requires 20MHz, and LTE-Advanced can take advantage of up to 100MHz.

Carrier aggregation solves the problem by combining discontiguous channels from different chunks of spectrum to make a higher bandwidth virtual channel that can support faster speeds.

Got Coverage?

This is one of the core features of LTE-Advanced, and some carriers and devices have begun to support this technology.
