Carrier Aggregation
Carrier Aggregation is a technology that helps mobile phones get faster internet speeds by combining multiple signal channels into one bigger channel. Think of it like turning several small roads into one wide highway for data. This technology is important in 4G LTE and 5G networks, making mobile internet faster and more reliable for users. When recruiters see this term, it usually means the candidate has experience with modern mobile network technologies and understanding of how to improve network performance.
