Is carrier aggregation the same as MIMO?

A primary component carrier (PCC) is complemented with one or several secondary component carriers (SCC) . The PCC handles all the control signaling while the SCC is used to increase the data throughput.

MIMO (Multiple Input Multiple Output) combines signals and data streams from multiple antennas to improve signal quality and data rates, whereas Carrier Aggregation (CA) combines multiple frequency carriers (channels) to enhance the bandwidth and data rates.

Carrier Aggregation is the foundation for deploying high-performing 4G and 5G networks . It provides the unique capability of aggregating several frequency bands for higher peak rates and increased cell coverage. Ericsson offers an industry-leading portfolio of Carrier Aggregation features for both 4G and 5G.

From Wikipedia, the free encyclopedia. Carrier aggregation is a technique that is used in wireless communication to increase the data rate per user, whereby multiple frequency blocks (called component carriers) are assigned to the same user .

Carrier Aggregation (CA) is a feature of LTE-Advanced that allows mobile operators & devices to combine two or more LTE carriers into a single data change . It leads to an increase in the capacity of the network and the data rates by exploiting fragmented spectrum allocations.
