It has been more than a year since three mobile communication companies started 5G service. In the meantime, there were constant quality complaints, but the government evaluated that the speed is far less than the content of the advertisement, and it is confirmed that the service is very limited.

In April of last year, the world's first 5G commercialization was expected to revolutionize.

The three mobile carriers advertised extensively that it is possible to transfer data up to 20Gbps, which is 20 times faster than LTE.

The results of the evaluation of the actual 5G service quality and the first evaluation in 1 year and 4 months have been released.

As a result of measurement in Seoul and six metropolitan cities, the average download speed of three mobile carriers is about 656 Mbps.

It was only 4.1 times faster than the LTE speed surveyed last year.

Of the multi-use facilities such as department stores and movie theaters, only 3,800 nations can use 5G.

However, 5G service was not smooth in a third.

Domestic 5G subscribers are close to 7 million, but they are not able to pay for expensive plans.

Since this survey is also a result of measurement in a place where 5G is built, consumers are exposed to inconvenience such as more frequent LTE conversions in daily life.

One of five dispute resolution applications received by the Korea Communications Commission over the past year has been related to 5G quality.

The three companies in Yitong plan to complete the 5G nationwide network in 2022, so quality complaints are inevitable.

Among the three mobile carriers, the fastest download rate is SKT, 5G access Among them, KT had the lowest rate of conversion to LTE, and it was found that connection safety was good.
