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.)

Rethinking Jan 27: Coronavirus could invalidate all projections. I reported on AIDS for 2 years. This could be worse because it spreads in air. Let us hope and pray.

Welcome  Asia is installing hundreds of thousands of 5G radios and adding 5G subs by the tens of millions. The west is far behind. 200,000,000 in 2020

The demand is there, and most of the technology works. Meanwhile, the hype is unreal. Time for reporting closer to the truth.
