How to test carrier aggregation in LTE-Advanced networks

In order to properly test LTE-Advanced, the test system needs to support a number of network test and verification features including support for carrier aggregation testing. For example, the Aeroflex TM500 Test Mobile was used in an early demonstration of LTE carrier aggregation at the 2011 Mobile World Congress, combining 800 MHz and 2.6 GHz

An Introduction to Carrier Aggregation Testing

Carrier Aggregation 2.1 Component Carrier Combination and Bands CA is realized by using up to five component carriers with a total maximum bandwidth of 100MHz, but initially only two carriers are deployed. Each component carrier can have bandwidths of 1.4, 3, 5, 10, 15 or 20 MHz. In FDD the number of aggregated carriers can be different in DL

How to test carrier aggregation in LTE-Advanced networks

This will not be possible with just a single carrier in the limited spectrum bands available to most operators. Consequently, carrier aggregation—the ability to combine multiple carriers scattered around the spectrum—will be a key measure to achieve the wider effective bandwidth that will be required, typically up to 100 MHz.

What is Carrier Aggregation Explained (2020) Beebom

May 19, 2020· 3 Types of Carrier Aggregation; In Carrier Aggregation, the component carriers are assigned in three ways. First off, when two or more component carriers belong to the same frequency band then they are placed together. This arrangement is called intra-band contiguous carrier aggregation. It’s the most common one in wireless communication.
