May 1, 2019. Korea has pulled far ahead in 5G, by almost every measure. Half the country is covered with 5G, with 90% expected by the end of 2019. Korea Telecom has 100,000 subscribers and the country 260,000. The hope is for 10% of users will be on 5G by the end of 2019, four to five million. SKT projects 6-7M subscribers by the end of 2020. That would suggest the three carriers will have 8-10M subscribers in a year. It will be difficult to impossible for any other country to catch up until 2021 or later. 

Takeaways: The government "suggested" the companies move quickly, effective industrial planning. KT CFO Kyung-Keun Yoon on its financial call said, "The investment into 5G is actually inevitable for us." I believe this pattern will be common: one company moves fast on 5G and the others feel they must match. Ericsson data is:

More than half in China, one-third in South Korea and one in four in the US and Australia will change either immediately or within six months should this be the case. 

Ericsson wants to sell radios and is not an objective source, but all indications are that if 5G is offered at the same price as 4G, consumers will buy. I expect this will especially be true later this year when numerous 5G phones hit the market at about US$600. 

Korea is deploying in 3.5 GHz, with an expected peak/laboratory speed of perhaps a gigabit. Consumer speeds should usually be 100-450 megabits down based on data from DT in Warsaw and Nikkei tests in Korea. Samsung is providing radios for KT & SKT; Huawei is servicing LG+. Nokia is behind schedule and is being replaced by Samsung in early plans. 54,000 base stations are active and the country is turning on 3,000 per week. 

The only phone is a US$1300 Samsung Galaxy, but the LG phone is expected shortly. Consumers are complaining about service problems. I'm optimistic they will soon be solved, but everyone is watching. 

Some government data.

Welcome On Oct 1, 2019 Verizon turned on the first $20B 5G mmWave network with extraordinary hopes. The actual early results have been dismal. Good engineers tell me that will change. Meanwhile, the hype is unreal. Time for reporting closer to the truth.

The estimates you hear about 5G costs are wildly exaggerated. Verizon is building the most advanced wireless network while reducing capex. Deutsche Telekom and Orange/France Telecom also confirm they won't raise capex.

Massive MIMO in either 4G or "5G" can increase capacity 3X to 7X, including putting 2.3 GHz to 4.2 GHz to use. Carrier Aggregation, 256 QAM, and other tools double and triple that. Verizon sees cost/bit dropping 40% per year.

Cisco & others see traffic growth slowing to 30%/year or less.  I infer overcapacity almost everywhere.  

Believe it or not, 80% of 5G (mid-band) for several years will be slower than good 4G, which is more developed.
