Nokias chosen use cases 230

According to a thoughtful 47-page analysis by the world's #3 manufacturer of 5G, Nokia. Looking at the top eight 5G use cases, Nokia confirms

"All are feasible with 4G."

 The inference: 5G is not essential for most of the progress in these areas*. As I looked further into each of these areas, it became clear none of them are likely to drive demand growth sufficient to raise carrier revenue significantly. **

5G will be good for the industry because it will lower costs and increase capacity, not because of new uses. In addition, most consumers believe the myth of 5G miracles and are likely to buy. One million Koreans signed on in the first two months.

5G phone prices will drop significantly sometime in 2020; China Mobile and Huawei predict prices from US$150 to US$300. At that point, I expect very rapid demand growth.

As Dean Bubley points out, we already would be seeing in the 4G era significant growth in any of these applications which have high demand in the near term. We aren't. Actually, the rate of wireless traffic growth in the West has been falling. Cisco, Ericsson, and your author expect the growth rate to continue to mostly fall. 

My guess is this will not change significantly past the 4-5 years of this report. The rate of technology change communications is so high any projections past 3-5 years are likely to be wrong. 

In particular, autonomous cars and video do not appear likely to require bandwidth that would break the trendline. Several applications likely to grow slowly are worth cultivating for future possibilities, especially AR & VR. 

Here are two illustrations. The first is from STL, showing estimates of low growth. Almost all analysts have similar conclusions. The second is the Nokia chart, larger.

*The inference would not be true if the 4G networks will run out of capacity. Fortunately, 4G technology already deploying can raise capacity 10X to 25X at a reasonable cost. Traffic growth is slowing significantly, except in China and India. Cisco estimates wireless traffic growth in the U.S. will fall to 30%/year by 2021. I have many confirming datapoints. Conclusion: Within today's carrier capital budgets, almost all Western carriers can supply the capacity needed through at least the middle of next decade. 

**The possible exception is fixed wireless, especially where Verizon will offer gigabit mmWave. In most countries, fixed wireless will likely be limited.

dave ask


Samsung has delivered 5G chip samples to BBK's Oppo and Vivo, the #2 or #3 phones manufacturer. Samsung is facing off against Qualcomm in the 5G market. Qualcomm is unfazed and reportedly moving the production of their next chip from TSMC to Samsung. 

Sprint's 2.5 GHz 5G is delivering 100-500 megabit downloads consistently. That bodes well for China Mobile, using the same frequencies.

Vodafone, BT, and soon 3UK are delivering modestly sized 5G mid-band networks. Vodafone is also live in Spain and Italy. 

Sunrise in Switzerland is using 5G mid-band for fixed wireless in rural areas.

Welcome  1,000,000 Koreans bought 5G in the first ten weeks. The demand is there, and most of the technology works. 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.
