Carrier Aggregation refers to the technique in which the modem aggregates multiple portions of the spectrum so that the user has greater bandwidth, resulting in higher data rates. Thanks to these developments, mobile networks are increasingly being used as primary Internet connections for offices, governments and stores.
The Carrier Aggregation technique combines two, three or more carriers in a single channel. These carriers can be of the same or a different band. With Carrier Aggregation technique, the regular data rate can double or triple by increasing the bandwidth. Carrier Aggregation for 5G is predicted to play an important role in extending coverage and increasing network capacity.
Kom in contactCarrier Aggregation is a technique that combines multiple frequency bands to give you bandwidth, resulting in faster data rates. In wireless communications, bands are spectra of specific frequencies used for communication between devices. If there is only one band to send and receive data, it takes longer to complete the operation. If you can put different frequencies together, you can communicate and send data in a fast and efficient way at the same time.
In Carrier Aggregation, multiple frequency bands are assigned to a single device. The frequency bands are also called component carriers. There are six specific frequencies: 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz. Of these, you can combine up to five component carriers to transmit a total bandwidth of up to 100 MHz. If you combine two component carriers together, we call it 2CA; if there are three components: 3CA, and so on. The more component carriers that are combined, the better the data rate.
In Carrier Aggregation, component carriers are allocated in three ways. First, through Intra-band Carrier Aggregation. When the component carriers belong to different frequency bands, they are placed in separate frequency blocks. This arrangement is the most complex variant, but produces a much better data rate. Inter-band Carrier Aggregation is further divided into two parts: Contiguous and Non-contiguous.
Contiguous Intra-band aggregation is the easiest form of LTE Carrier Aggregation to implement. In this case, the carriers are contiguous. In this case, you only need a single transceiver, since the signal is considered a single augmented signal.
Non-contiguous intra-band Aggregation is somewhat complicated because the component carriers come from the same frequency band but are separated by a spectrum gap. So you need two transceivers because the signal cannot be treated as a single signal, which increases complexity and cost.
By increasing throughput (the time it takes to transmit data from one location to another), the network can deliver fast data to users in the targeted geographic area. This means that Carrier Aggregation increases network capacity, which helps to increase mobile data rates.
In addition, Carrier Aggregation also increases download and upload speeds, enables seamless playback of high-resolution videos, and allows large files to be downloaded in less time. With Carrier Aggregation, you can provide multiple users with a seamless experience and the ever-increasing demand for bandwidth in the office.
What is the difference between bonding and carrier aggregation?
With bonding different WANs – think 4G, Fiber, VDSL – are combined so that a larger bandwidth can be realized. The difference with CA is that with that technique the router can simultaneously be connected to 2 or more 4G/5G frequency bands or channels of the mobile network of 1 mobile network operator.
