Germany latency Open Signal 230The typical latency difference between existing 4G and new 5G is about 10-15 ms. 5G latency in 2019 is ~30 ms in independent tests in the US, Korea, and England.  The latency is about the same in the other two dozen 5G deployments in 2019. That's what 5G equipment is designed for. 

The chart is based on Open Signal data from Germany early in 2019. In LTE, Vodafone had 40 ms latency and Deutsche Telekom 42 ms. That's higher than the 30 ms typical of 5G, but not wildly so. Very few applications will be affected. 

Latency on LTE networks will continue to fall as older equipment is replaced. New LTE equipment from Ericsson & Huawei brings air latency down to ~13 ms, only 3 ms more than today's 5G.

Latency will be reduced in many locations with Edge Networks (all of China) and/or improved backhaul/transport. (Verizon is doing both over the next few years.)

4G latency tests around the globe generally produce results between 35 and 55 ms. One LTE test at Verizon showed 23 ms and more than 55 ms is not uncommon. 

1 ms latency is a myth outside the labs for years.

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.
