Carrier Aggregation in Indian Telecom Networks

Carrier Aggregation (CA), a feature of LTE Advanced enables telecom operators and devices to combine two or more Long Term Evolution (LTE) carriers into a single data channel. The CA enables telecom operators to enhance the capacity of the data rates and the entire network by capitalising on fragmented spectrum allocations. The operators can apply the LTE Advanced feature either on their LTE Frequency Division Duplexing (FDD) variant or on the Time Division Duplexing (TDD) LTE variant with up to five component carriers. It has been said that the five component carriers can deliver up to 100 Mhz of total transmission bandwidth for a telecom operator.

Smartphones Supporting CA Delivers Higher Internet Speeds

The devices supporting CA offer users better speed and network connectivity as compared to devices with no support for CA. The CA enabled devices can club multiple LTE connections and treat them as one as compared to non CA devices that typically dial one LTE connection between the phone and the network. The devices supporting CA when latched onto a supporting network would deliver double or higher internet speeds due to the enhanced connectivity.

With the CA enabled devices, the users can prevent minor lags during online gaming while also preventing buffering when watching a high-definition video that are often caused by patchy networks.

Crucially, the CA enabled devices also prevents network oscillations that results in the smartphone delivering higher battery life.
