Realme V3 230The Realme V3 5G  has a 6.5-inch screen, three rear cameras, and a 5,000 mAh battery. The Mediatek Dimensity 720 is similar to the popular Qualcomm 765 in Antutu testing. It should be fine for most practical purposes, although the main camera has only 13 megapixels. 

CEO Xu Qi expects to sell 50 million phones this year and soon reach 100 million. Realme, Oppo, Vivo & OnePlus are brands of BBK. Added together, in some quarters they are #2 in worldwide phone sales. They spend $billions on research.

 I'm probably going to raise my 2020 yearend estimate of 210,000,000 5G subs because of the low prices and rumors about iPhone 5G.

Qualcomm and Ericsson claim a "groundbreaking milestone" delivering millimeter wave 5G almost 4 kilometers. NYU Professor Ted Rappaport did 11 kilometers four years ago. Qualcomm's actual achievement is making the antenna smaller than the one Ted used. They should at least have acknowledged his work. See  from December, 2016

Put one radio high enough to provide line of sight and use directional antennas and of course mmWave can go a distance. It requires the perfect topography, although a radio on top of a high tower may have some practical use.

In the next few months, Verizon and others will be demonstrating new antennas that may solve the catastrophe that was early mmWave. Verizon in 2017 thought it would get 600-1000 meters of reach. In practice, it was often less than 200 meters. Verizon stopped taking orders although the publicity never stopped.

Ted pointed out:

Many people continue to propagate the incorrect myth that mmwave is severely limited in distance. This is not accurate. The fact is that the distances at mmwave will only be limited by rain and fog, not by the nature of mmwave. This is because the "lossiness" of mmwave, compared to lower frequencies, only occurs in the first meter of propagating distance, but this "higher loss" is canceled out by keeping the antennas the same physical size at all frequencies.

TSMC 7 nm 230Kevin O'Buckley of Marvell tells EE Times, “We’ve been able to achieve on average 40 percent lower power for a given design point and performance point. We’ve been able to achieve 40 percent greater integration, mostly measured as die area shrink, which can be used either to pack in more performance in a given die area or in some cases, lower costs.” Marvell finds, "TSMC’s 5nm technology which delivers approximately 20 percent faster speed or 40 percent power reduction compared to the previous 7nm generation."

Moore's Law is slowing down, but how much? Far too many claims are made based on inappropriate comparisons. O'Buckley answered me, "40% lower power was by taking some key designs in N7 and moving them to N5 at fixed performance (and lower voltage.)" (There is an immediate process, TSMC's N7+, which uses EUV.)

5G in China now has about 100 million subscribers but the results in the West have been dismal. T-Mobile is bringing lower-priced phones to the U.S. while upgrading ~3,000 towers per month. On the lightly loaded network, speeds average over 300 Mbps. A promotion drives the cost down to $200.

1/3rd of the U.S. will be covered with mid-band 5G yearend, and They won't stop. TMO has passed AT&T to become #2 in the U.S. and is going after Verizon. For at least a year and possibly two or three, TMO will have a much better network.

Both Verizon and AT&T have been cutting capex and praying consumers won't care that most of their "5G" is slower than decent 4G. Verizon's mmWave Ultra is the fastest network in the world, but 5G customers connect to it less than 1% of the time.

Zain KSA Riyadh 230 A. sent this speedtest from his 5G home router in Riyadh. 248 Mbps down, 5 Mbps up, and a remarkable ping of 17 ms. Opensignal average 5G speeds in Saudi Arabia test at 414 Mbps, highest in the world. See . His note:

"I have been a subscriber of 5G for my home internet with Zain KSA since last January. At the beginning, the internet was extremely slow (actually lower than 4G). However, the internet has been gradually improving lately I suspect that is related to the higher deployment of 5G small cells around my areas."

The low ping is surprising, lower than Verizon and almost all 5G worldwide tests. It implies that Zain has a new, state-of-the-art system for backhaul and core transport. While the headlines go to the latency of the 5G radio, the backhaul often has a larger effect. Verizon One Fiber has more impact on latency than anything related to 5G. 

The Gulf and Korea have gone faster to 5G than any others. 

5G speeds Opensignal August 2020 230

Opensignal released the first international comparison of 5G speeds. I was startled to discover that Saudi Arabia is far ahead in both coverage and speed. I did a little research and discovered that SA, along with the Gulf countries, is further along than anyone in Europe.

The average 5G speed in SA was 414 Mbps, In the USA, it was 51 Mbps, slower than 4G in Canada and most major US cities. Most U.S. connections were low-band, which by its nature tends to be slower than 4G.

Saudi Telecom has upgraded 3,000 of its 7,000 towers. Zain claims it has even wider 5G coverage than STC. Opensignal found that Saudis connected to 5G 34% of the time, leading the world. Kuwait was second, at 29%. It doesn't have data yet for the UAS or Qatar, but I know both also have relatively good coverage.

Korea was second, at 312 Mbps. That's less than half the figure of the Korean government, but much closer to results in other countries using similar spectrum to the Koreans. See . The Koreans have over 7 million 5G subscribers, 2nd or 3rd in the world.

Saankhya 5G RU 230Parag Naik is seeking government support for a 5G radio unit base on its software-defined radio chipset. He tells  ETTelecom's Muntazir Abbas

"The government needs to think strategically with a 5-year plan of building telecom gear giants in India with monetary and market support. It has to incentivize more R&D investments in this sector. ...  Our 5G Remote Units will be available from Q1 of 2021.

We have around 65 patents on [cognitive radio and 5G broadcast]. ... DoT can play a major role in carrying out the actual implementation of Atmanirbhar Bharat. ... Building RAN chipsets and solutions is a capital-intensive business, we need monetary support and market access to mature some of our solutions. Telecom network equipment requires a lot of field testing, trials, and hard for any new player that comes along. This is the only way to make Indian companies globally competitive."

Atmanirbhar Bharat (Self-reliant India) is India's answer to Made in China & Made in the U.S.A. Indian protectionism is succeeding in moving some phone manufacturing to the country.

70+% of phones purchased in China in 2021 will be 5G, so it's no surprise GM will start upgrading telematics to 5G. By 2022, about 80% of China will have 5G coverage. Parts for 5G have been coming down rapidly in price. The 5G upgrade will probably add about five dollars to the cost.

GM will also start incorporating V2X & V2V intelligent technologies. Those will probably work fine in 4G, although 5G has the theoretical ability to handle a million connections per square mile. So far, I've never found a system that requires more connections than 4G can handle.

The U.S. blockade on advanced chipmaking gear to China may cause a problem for GM. GM is strongly committed to "almost all parts coming from local suppliers." UNICOM, a Chinese company, is now making a 5G chip that could be manufactured at 12 nm in China. But the most advanced 5G chips require EUV lithography, only available from ASML in the Netherlands. The U.S. is currently blocking ASML from shipping the machines to China.

China is working hard on a Chinese EUV tool, but until that becomes available, GM will have to choose between sacrificing 5G performance or importing 5G chips.

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.

I'm Dave Burstein, Editor. I've been reporting telecom since 1999. I love to hear from readers and say thank you when you find an error.
