Mobile phones are the easiest device to use in this generation. Mobile phones, mobile phones, mobile phones, mobile phones, handhelds, handhelds, or pocket phones (sometimes simply abbreviated as mobile phones, mobile phones, or just phones) can make calls over radio frequency links. It is a mobile phone that you can receive. The user moves within the  telephone service area. Today we are gradually using the internet. But we were also unaware of many things on our phone and in our lives. The term "carrier aggregation" is overshadowed by our vision. Now it's time to know: what is carrier aggregation?  

            Before that the mobile towers are carriers which connects through the internet. It sends the frequencies to our mobile phones.

An easy way is to connect the pipe  to the tank and fill the  empty container with the pipe. On the other hand, three pipes are connected to the same tank, and the pipes can fill the same container. Yes, we all  know that the second will fill up soon. The same concept applies to carrier aggregation. If a cell phone receives multiple frequencies from the nearest cell tower, it means that carrier aggregation is enabled on that cell phone and cell tower. Various types of carrier aggregation are available here. These are 1CA, 2CA, 3CA, etc ...  

If the mobile phone receives only one frequency from the cell tower, it is 1CA. When it receives two frequencies, it becomes 2CA and continues ... Mobile phones that support 1CA can receive a frequency band of up to 20MHz, and  2CA can receive a frequency band of up to 40MHz. When receiving three frequencies, 3CA can receive a frequency band up to 60Mhz and then move to a multiple of 20Mhz. The question arises here. How do you determine if your mobile phone supports carrier aggregation? The next step is as follows: A plus icon appears in the notification bar. These are the ones that need to be supported by carrier aggregation. It must first be supported in hardware, then in the mobile phone's operating system, in support of processor continuity, and finally in carrier aggregation in the cell tower  connected to the mobile phone. .. The carrier aggregation SIM has been activated and must be inserted into the first SIM slot. First and foremost, it  depends on where you receive carrier aggregation and your network. This is UNNOTICE DPLUS, which is our life and is now in the spotlight.
