The best results are on track. Korea Telecom is using 100 MHz of spectrum at 3.5 GHz and tested at 193-430 Mbps down. Upload was at 4G speeds. Verizon is using 400 MHz at 28 GHz and the best results were 600-900 MHz. Note that these almost all were clear line of sight, no windows or walls, and only a short distance. Two tests through windows saw a 60-80% drop-off.

Speeds will probably go up as the equipment improves; speeds will probably fall as more people connect. Below, a table with 7 independent test results. More very welcome.

430 Mbps corresponds to what Deutsche Telekom measured on a similar system in Warsaw and what Sprint & T-Mobile expect when they turn on their 5G:

In “daily-use” cases (farther away from the station, on a street, in our #5G_LAB building) we are registering speeds around 350-500 Mbps, which is really great considering the circumstances.

85% or more of "5G" will be similar to the Korean and DT systems. Verizon and AT&T mmWave should be about three times as fast.

600-900 for 400 MHz mmWave is actually more than the 450 megabits Verizon press release suggested. (Below) 400 MHz should provide 2-5 gigabits shared in the lab and often reach a gigabit to individual users. Verizon has 800 MHz to eventually use. No carrier has suggested consumer speeds above about a gigabit, although two gigabits should be practical for fixed wireless with larger antennas. 

Lots of bugs, inconsistencies, and problems have to be fixed but the best results are on track. 

Verizon estimated latency would be less than 30 ms. Actual tests were 16-26 ms, probably because of Verizon's improved backbone/transport. An Edge cloud brings latencies to 15-20 ms consistently in Verizon and AT&T labs. Verizon has said they will start deploying an Edge Cloud later in 2019.

LTE averages 40-55 ms latency on the currently deployed systems, a few years out of date. Sascha Sagan of PC MAG found LTE latency of 25 ms at Verizon Chicago. (Sagan has been doing consistently valuable testing. Michael Thelander of Signals Research found LTE and 5G latency very similar in an email to me but emphasized this is very early.

Ericsson and Huawei's new radios can bring LTE "air latency" down to 10-13 ms, close to the 8-12 ms of 5G NR today. 5-30 ms must be added to air latency for the time from the tower to the server. URLLC can reduce air latency to 1-5 ms, but that will be mostly in the labs for years. 

The "1 ms latency" and "10-20 gigabit speeds" for consumers are fantasies or worse.

Here are the first 7 independent tests in the U.S. and Korea, followed by Verizon's press release.  Measured results at Verizon were better than the press release claims.

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.
