S. Korean telcos to share 5G networks in remote areas

Can you even imagine? US telco’s are too busy entrenching to do anything like this for the public good.

S. Korean telcos to share 5G networks in remote areas:

South Korea’s three major mobile carriers will share their 5G networks in remote coastal and farm towns in a move to accelerate the rollout of the latest generation networks, the ICT ministry said Thursday.

The carriers — SK Telecom Co., KT Corp. and LG Uplus Corp. — signed an agreement so that 5G users can have access to the high-speed network regardless of the carrier they are subscribed to in 131 remote locations across the country, according to the Ministry of Science and ICT.

Under the plan, a 5G user would be able to use other carrier networks in such regions that are not serviced by his or her carrier.

The ministry said telecom operators will test the network sharing system before the end of this year and aim for complete commercialization in phases by 2024.

The ministry said the selected remote regions are sparsely populated, with a population density of 92 people per square kilometer, compared with those without network sharing at 3,490 people per square kilometer.

The move comes as the country races to establish nationwide 5G coverage, with network equipment currently installed in major cities.

The three telecom operators promised in July last year to invest up to 25.7 trillion won ($23.02 billion) to update their network infrastructure by 2022.

As of February, the country had 13.66 million 5G subscriptions, accounting for 19 percent of its total mobile users. South Korea was the world’s first country to commercialize 5G in April 2019. (Yonhap)

Alerting resembles action

Let’s talk about security fatigue for a minute.

Korean COVID-19 text alerts to be reduced amid public weariness:

The central and local governments will reduce their emergency coronavirus text alerts amid mounting complaints that frequent arrivals of such messages have increased the public weariness in the prolonged pandemic, the interior ministry said Wednesday.
The revised guidelines for coronavirus-related text alerts, which go into effect Thursday, require only essential information to be sent out to the public and for the alert system to be turned off between 10 p.m. and 7 a.m.

To deal with growing public fatigue on the matter, the Ministry of the Interior and Safety specifically banned releasing information such as detailed reports on new patients and their itineraries, already widely known virus rules and promotions of local governments’ virus responses.The emergency notification system has played a key role in containing COVID-19 by swiftly delivering relevant information, including details on new infection cases and antivirus measures.

There was one day last week where I received 7 alerts across my iPhone and Apple Watch. That’s 14 unactionable alerts, many of them coming stacked like in the image above.

More than 15,500 such messages were sent out by state authorities from January to February, which translates into a daily average of 263, according to data compiled by the ministry.

The figure jumped six times from 2,711 recorded in the same period last year when the country was at the early stage of the pandemic.

Never mind the fact that they are only in Korean. Most often the alerts are purely informational. They would often include a URL that pointed to the same data on-line.

But at the same time, more people have complained of its excessiveness and redundancy, with the same information available on the central and provincial governments’ websites and social media pages.

… “It is time to shift how the text alert system works considering the persistence and routinization of the pandemic,” Interior Minister Jeon Hae-cheol said, asking people to better utilize online information made available by authorities. (Yonhap)

I work with customers who have their Security Operations Center (SOC) set up to do the above – alert excessively on things that are informational or aren’t actionable or have relatively low impact to the customer. Why?

Alerting resembles action.

The (not so) new pollution

Smog in Seoul
Ultrafine dust density soars to ‘very bad’ level in greater Seoul:

The greater Seoul area was blanketed by extraordinarily heavy concentrations of locally generated ultrafine particles on Friday, but its air quality will return to normal over the weekend due to rainfall, a state monitoring agency said.

The institute forecast that the density of ultrafine and fine particles will remain at bad to very bad levels in the central region, including Seoul, throughout the day, as locally generated air pollutants accumulate due to stagnant atmospheric conditions.

But the central region’s air quality will return to normal beginning Saturday afternoon due to atmospheric diffusion and rainfall, it said. (Yonhap)

When I woke I could only see about 4 blocks. Turns out it wasn’t my eyeglasses needing a good scrubbing after all.

My nightmare

That stair is my nightmare.


I have a recurring nightmare where I am climbing a stair outside of a tall building. “No one would put an exposed staircase outside of a building at that height,” I told myself.

I lived happily in that lie for years.

That lie is no more.

I took the pictures from the 37th floor … and shot up!

Korea day 19 breakfast

It’s a COVID-buffet at the hotel. I am uncomfortable with a) the crowd, and b) the buffet.

The coffee is burnt as well.

That is what I grabbed on a fast attack mission into the sea of humanity:

  • Salmon
  • 2 buns of unknown type
  • Yogurt

This is, without a doubt, the worst breakfast I’ve had in Korea.

The buns are nothing but steamed dough.

Disappointing. I will have to plan my weekend breakfasts accordingly.
