What is carrier aggregation and why is it used?
Carrier aggregation is a technique used in wireless communication to increase the data rate per user, whereby multiple frequency blocks (called component carriers) are assigned to the same user.
The sum data rate of a cell is increased as well because of a better resource utilization..
What mean LTE?
Long Term EvolutionLTE stands for Long Term Evolution. It’s a term used for the particular type of 4G that delivers the fastest mobile Internet experience. You’ll usually see it called 4G LTE. Using a 4G smartphone on Verizon’s 4G LTE network means you can download files from the Internet up to 10 times faster than with 3G.
What is LTE component carrier?
The CCs can be of different bandwidths. Each aggregated carrier is referred to as a component carrier, CC. The component carrier can have a bandwidth of 1.4, 3, 5, 10, 15 or 20 MHz and a maximum of five component carriers can be aggregated, hence the maximum aggregated bandwidth is 100 MHz.

Is LTE a cellular network?
When describing cellular networks, you’ll commonly hear the terms 3G, 4G, and LTE. This identifies the generation of network technology: 3G, or the third generation network, was developed before 4G. … LTE stands for Long Term Evolution, and currently 4G LTE is the most advanced option available.
Is 4g and LTE the same?
LTE, sometimes known as 4G LTE, is a type of 4G technology. Short for “Long Term Evolution”, it’s slower than “true” 4G, but significantly faster than 3G, which originally had data rates measured in kilobits per second, rather than megabits per second.
