I checked the 5G speed in the shopping mall.

The average speed is around 500 megabytes per second.

It is far short of the promise of 20 gigabytes, which is 20 times faster than LTE.

[Kim Young-ji |

Gwanak-gu, Seoul: I don't know if (5G) is that fast enough to feel it.

I don't know how to feel it, but I think it's burdensome to have to pay 5G (fee).]

5G service uses a frequency of 3.5 gigahertz or 28 gigahertz, but 20 times the speed is possible at 28 gigahertz frequency.

At the time of frequency allocation in 2018, telecommunication companies promised to install 45,000 28 GHz base stations, but the current installation is only about 10%.

This is because 28 gigahertz is expensive because of its short reach and the need to install many base stations.

Telecommunication companies have created so-called hotspots by installing 28 gigahertz base stations in 11 crowded areas, such as baseball fields.

However, after the pilot project, some areas have stopped service.

He also promised to open 28 gigahertz high-speed Wi-Fi in Seoul subways by the end of the year.

I went to the subway and checked the speed.

On average, it is around 400 megabytes, which is faster than the existing Wi-Fi, but it does not reach the 700 megabytes set by the government as a target.

Many sections have not yet been approved for installation of optical cables and routers.

Due to the poor network, even smartphone manufacturers are not releasing terminals that can use the 28 GHz frequency.

[Byun Jae-il |

Member of the National Assembly Science and Communications Commission: Four years have passed since the (28GHz frequency) was allocated.

However, it has not been used properly so far.

In a way, it is even pointed out whether this is a failure of the 5G policy.] The

28 gigahertz frequency allocation period is scheduled to end in the second half of next year, and the Ministry of Science and ICT, the main ministry, is only looking for ways to use it for the fourth year.
