What are 5G, 4G LTE, 4G+, and Carrier Aggregation?

Today we’ll discuss the carrier aggregation system & how 4G and 4G+ work. We’ll know how it’s able to deliver a better 4G experience!

Now the question is, what is this carrier aggregation? – Analysis of its name like various technical terms but within its name. The word aggregation in English means “unification”. This means that the technology of integrating multiple careers is called carrier aggregation. But wait, it doesn’t end there. Much remains to be said about carrier aggregation. Although these things are very complicated and technical. But, fortunately, we are here, and we’ll try to make everything as simple as we can.

5G Network

However, first, we need to know how your phone uses 4G technology. In Bangladesh, 4G services are available using three bands. 900Mhz, 1800Mhz, and 2100Mhz – 4G but many bands support which was not seen in previous 2G or 3G technology. This is why it is called LTE or Long Term Evolution. So that this service can be provided through different frequency bands.

In the past, mobile operators used 2G or GSM services using the bands of 900 MHz and possibly 1600 MHz. But when 3G comes, they have to adopt 2100 MHz. But there is no need to use any specific band for the 4G service, it supports different bands, so it is possible to provide 4G service from existing bands.

4G band support is really unmatched, our country basically provides 3G using 3 bands but it supports many more bands. Such as – 1900Mhz, 1700Mhz, 2600Mhz, 1500Mhz, and many more bands. You can see the details here.

What happens now is that when you are in the room the 1600 MHz signal gets much less so the phone gets connected to 900 MHz. Since mobile devices are designed to receive better signals. You may have noticed that when 4G is weak in your location, the phone automatically goes into 3G or 2G mode. The phone always tries to stay connected to the network to get the best signal.

Yes, this is exactly what the career advancement system works on. The technique of providing more bandwidth than just joining one band at a time rather than joining multiple bands or multiple carriers is called carrier aggregation. Your phone may be connected to two or more carriers, in which case the bands may be completely different or may be connected to multiple carriers in the same band. Simply put, it’s like using two or three internet connections at the same time. In that case, you can understand that the speed will be high.

4G Network

Suppose you were using 16G band 4G on a single channel, which would support bandwidth up to a maximum of 20 MHz. Suppose you were getting 100 megabits of speed (although this is a fantasy for us, so I told you to keep it in mind). Now if you connect to two more carriers through carrier aggregation, 2-3 times the speed can be provided effortlessly. In that case, you can consume bandwidth from 3 links.

There are basically two ways to aggregate a career. The first is called Intra-band Carrier Aggregation, where a single band can be used to split the band into a maximum of two parts, but the signal has to be quite wide. This is what most operators want to implement because it is much easier to set up and costs less. Signals can be transmitted from just a single transceiver.

3G Network

I realized that it is possible to fix the slow 4G speed through carrier aggregation. But how can that be used? – Now in this case there must be support from both sides. First of all, your mobile operator needs to support carrier aggregation, which means they need to provide a 4G + network. Second, your phone must be carrier forwarding supported or (CA) supported.

Now you need to know if your operator supports 4G +. As far as I know, Grameenphone and Banglalink only provide 4G in the 1600 MHz band. I don’t know about Banglalink but Grameenphone supports 4G + in some areas. Robi / Airtel, on the other hand, supports 4G in both 900 MHz and 1600 MHz bands. They used to support carrier aggregation but now I see a single band working on 4G. However, in some areas, I still see 4G + support.

You can easily check yourself, whether your operator supports 4G +. Basically, the 4G + icon e shows on many phones. However, from an app called Netmonster, you can easily find out which band your operator is providing 4G and whether they have carrier advancement support.

Here my operator Airtel has single band 4G with no carrier progress support. If supported, it would look like the screenshot below, with 1800 + 900, 2CC text, or 3CC text will appear in the status bar of the phone.
