How to test carrier aggregation in LTE

Jun 27, 2021For LTE-Advanced, 3GPP Release 10 introduced several new features to augment the existing LTE standard, and these are aimed at raising the peak downlink data rate to 1 Gbps and beyond, as well as reducing latency and improving spectrum efficiency. Targets have also been set enabling the highest possible cell edge user throughput to be achieved.
