Recently, a friend asked: now the world is vigorously studying 5G (with the exception of Huawei, Huawei has begun to study 6G), is there still room for 4G? Will it be eliminated as quickly as the previous 2G and 3G? On this issue, let's have a chat today (just represent your personal opinion)!

Make every effort to develop 5G technology

2019 is an important year for fifth-generation wireless connectivity. More than 40 operators around the world have opened their 5G networks at an unprecedented speed. By contrast, only four networks were enabled for 4G LTE in the first year. This is a very remarkable thing.

Let's first take a look at the milestones in the development of international communications:

The United States recently added AT&T and T-Mobile and launched their 5G network. Sub-6 refers to 6 gigahertz (or lower) spectrum, which provides a wide range of coverage, but does not have super capacity and speed, or will be the main advantage of 5G. The latter will take longer, and operators will need to invest heavily in infrastructure to deploy in 5G.

On December 6th, wireless network operator T-Mobile launched its first national 5G network in the 600MHz band, covering more than 200m people in the United States. They also began offering the first two 5G phones in stores. Compared with 4G LTE, the performance of its 5G Sub-6 network is improved by 20%.

On Dec. 12, wireless network operator AT&T opened 5G Sub-6 networks in 10 markets for consumers, provided they also bought the only phone that currently supports this feature: Samsung Galaxy Note10 + 5G.

Verizon has achieved its goal of providing initial 5G UWB (also known as 5G mmWave) services in 30 cities in the United States. The overlay is available here.

Other operators have begun to launch 5G on a limited basis and will expand it in the future.

4G to 5G migration planning

The exciting thing about 5G is that it has unprecedented speed and low latency, which makes many people want to adopt it as soon as possible. Jumping on the bandwagon is more important than jumping into the competition. Others recalled (and surprised) the experience during the shutdown of 2G and 3G networks and wanted to make sure they were not caught off guard.

Fortunately, as 5G is gradually introduced over the next few years, 4G LTE will remain safely in place. In fact, due to a new technology called dynamic Spectrum sharing (DSS), 4G LTE is not expected to be operational until at least 2030, and may even take longer, which will allow 4G and 5G networks to share the same frequency band, thus speeding up transmission. The launch of 5G and the life of 4G LTE.

With that in mind, companies eager to take advantage of 5G don't have to wait for it to become cheaper or more widely distributed. Instead, companies can start modernizing with 4G LTE technology to validate applications and business models. Then, as 5G becomes more widely available, they can be refined and expanded. Connect 4G LTE and accelerate 5G.

If you want to know why the old "G" must be completely eliminated, it is only due to limited spectrum problems. With the emergence of a new generation of cellular technology, network operators need to turn off the old technology in order to reuse the spectrum and reuse the spectrum. Because the new generation of devices are more efficient, they can transmit more data faster over the same spectrum bandwidth.

So, we boldly use 4G, at least for a long time 4G will always exist! After all, 5G to cover all aspects of the need for a long period, after all, the signal base stations need to pay for!

OK, the above is our discussion on 5G and 4G technology, more product-level specifications and product knowledge, you can consult in the product center or contact customer service personnel!
