Nevile Ray Signature 230Only wireless engineers will believe Neville Ray's sworn statement, "We have publicly announced that we will commence building the T-Mobile 5G network in 30 cities, including New York, Los Angeles, Dallas, and Las Vegas, during 2018. Because 5G-capable devices are not yet available, we do not anticipate offering 5G mobile services until sometime in the first half of 2019. This network build will include approximately xxx cell sites and will provide an average throughput of 25 Mbps."

AT&T's 4G network averaged 70 Mbps in May of 2019 and T-Mobile slightly over 50 Mbps. (PC Mag, picture below) It's usually higher now, especially where equipment was upgraded for 5G.) On 4G, PCMag actually tested live service in Manhattan at over 500 Mbps. (Using advanced LTE & LAA.)

25 Mbps average for 5G must be impossible, right. WTF?

What every wireless engineer knows is that low-band 5G is really 4G with some software, 5G NR. 5G NR does almost nothing for performance.

(That was in 2018. Some things have improved and I wouldn't be surprised it's up to 50 Mbps.)

CFO John Stephens says AT&T is going to cut capex soon.

Bharti in India has lost 45M customers who did not want to pay the minimum USS2/month. It's shutting down 3G to free some spectrum for 4G. It is cutting capex, dangerous when the 12 gigabytes/month of use continues to rise.

Huawei in 16 days sold 1,000,000 5G Mate 20s.  

China has over 50,000 upgraded base stations and may have more than 200,000 by yearend 2019. The growth is astonishing and about to accelerate. China will have more 5G than North America and Europe combined for several years.

5G phone prices are down to $580 in China from Oppo. Headed under $300 in 2020 and driving demand.

No one believed me when I wrote in May, 90% of Huawei U.S. purchases can be rapidly replaced and that Huawei would survive and thrive. Financial results are in, with 23% growth and increased phone sales. It is spending $17B on research in 2019, up > 10%.

Welcome  1,800,000 Koreans bought 5G in the first four months. 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.
