3 years ago, 5G service, which was said to be 20 times faster than LTE, started, but it is difficult to hear that they enjoyed this speed properly.
It is pointed out that the investment is slow due to the cost, although it is possible to enjoy this speed by installing more ultra-high frequency base stations in various places.

I measured the 5G speed at 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.
5G service uses a frequency of 3.5 GHz or 28 GHz, and 20 times the speed is possible at 28 GHz.
At the time of frequency allocation in 2018, telecommunication companies promised to install 45,000 28 GHz base stations, but only 10% of them are currently installed.
This is because 28 GHz has a short reach and requires a lot of base stations to be installed, which is expensive.
Telecommunication companies have created so-called hotspots by installing 28GHz 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 28GHz 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.
Many sections have not yet been approved for installation of optical cables and routers.
[Byun Jae-il/Member of the National Assembly Science and Communications Commission: 4 years have passed since the (28GHz frequency) was allocated.
However, it has not been used properly so far.
In a way, it is pointed out that this is not a failure of the 5G policy.]
The 28GHz frequency allocation period is scheduled to end in the second half of next year, but the Ministry of Science, Technology and Information and Communication, the main ministry, is only looking for ways to use it for the fourth year.
