How To Check Carrier Aggregation On Your Phone

How To Check Carreir Aggregation Support

Carrier Aggregation was first unveiled in the year 2015 by 3GPPP. After which the OEMs and SoC manufacturers started to implement this so that further it can be used on mobile devices. Carrier aggregation can be helpful to a lot of users when it comes to connectivity of the internet or getting good and stable high-speed internet. So if you are unaware of carrier aggregation then go ahead and have a read to this article and I am sure you will get a lot of information about carrier aggregation, its working and there is a guide on how to check carrier aggregation on your phone so make sure to check that out if you want to know whether carrier aggregation is present in your smartphone or not.

What is Carrier Aggregation?

Carrier Aggregation is basically a technique that is used by the telecom brands and OEMs that combine more than one frequency bands to offer more bandwidth which leads to faster internet and better stability of the internet. Bands play a major role in wireless communication as they are the spectrums of specific frequencies which are used for communicating between devices. Consider it like the time taken to transfer data if there is only one band which is used to send and receive data and the time is taken for the same data to transfer with the help of multiple bands, the speed of transferring the same data could be double or even triple depending on the number of bands you are connected to.

As we all know by now that for carrier aggregation multiple frequencies are involved for a single device, so they are called component carriers and have six specific frequencies:1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz. usually, a user at a given specific time can combine only up to 5 of these component carriers to transmit the aggregated bandwidth of up to 100 Mhz. Aggregating two component carriers will be called 2CA. Similarly, for three-component carriers it would be called 3CA and so on.

Types of Carrier Aggregation

For Carrier Aggregation the component carriers are usually assigned in three ways.

  1. So when two or more component carriers are of the same frequency band then they are placed together. this is called intra-band aggregation. The intra-band carrier aggregation is one of the most common methods used in wireless communication.
  2. However, if the same intra-band carrier aggregation are of the same frequency but are separated with a spectrum gap then it is called intra-band non-contiguous carrier aggregation.
  3. Finally, if the carrier aggregation are done with different frequencies then they are not placed together instead are placed in a separate frequency block. This is called inter-band carrier aggregation and not to mention this is the most complex method of aggregating the frequencies, but in return, this is the one that gives out the most data speeds.

One major advantage of Carrier Aggregation is that it also helps in balancing the load in the transmission of data. Allow me to explain, most of the frequency band which are used in carrier aggregation or even in general has a primary component carrier called as PCell and an SCell(Secondary cell). So whenever, the PCell is fully occupied and cannot take any more load, then the SCell gets activated for data transmission, thus it eases the load of the PCell and it also gives faster data transmission as it works simultaneously.

How it Helps General Users

If you are someone who wants better connectivity and higher data speeds on your device no matter what then make sure before you purchase your next smartphone it dies support 3CA or 4CA arrangement. If your device would be having this then it will give good data speed even when the signal is pretty low, thus carrier aggregation is a must in a 2021 modern smartphone. Recently, Qualcomm introduced a new modem which is used in most of the smartphones that are powered by Qualcomm’s chipsets, the modem is called an X5 LTE modem and it comes with a 2CA arrangement.

Most of the Xiaomi and Redmi devices have been reported that it misses any type of carrier Aggregation even with the hardware being present it is disabled by software. When it comes to Carrier Aggregation OnePlus and Samsung does the best as far as we have tested.

How To Find Carrier Aggregation Support on a Smartphone?

if you have an Android device with whom you want to check the support of Carrier Aggregation then simply download this NetMonster app from Google Play Store.

  1. After you have finished installing the app, open the app and inside it, you will see the band combination mentioned on the top of the page.
  2. If it shows a + sign with the band frequencies then it means that your device supports carrier Aggregation.

It also depends on the area or the region you are living in or the network provider as well. There could be a scenario where your device might support carrier aggregation but your current location doesn’t have such bands which support carrier aggregation so it won’t show up.

Final Verdict

So with the help of Carrier aggregation, you can get high-speed internet and better connectivity as well. Make sure you choose the right network provider that supports Carrier Aggregation and the right smartphone which has support for Carrier Aggregation. For instance mostly, in metro cities, almost all of the big network providers do support Carrier Aggregation.
