$300 5G OnePlus Nord N10 T-Mobile. The 5G explosion moves west.

The OnePlus 6.5" 1080 screen with a 90 Hz refresh rate. It has a 64 megpixel main camera and three other cameras. A 30 watt charger is included. (Take that, Apple) The Qualcomm Snapdragon 690 is fast enough for almost all practical purposes. 

T-Mobile already covers a third of the US (100M+ pops) with mid-band 5G. CTO Neville Ray says median speeds are 300 Mbps, although that may go down as the network gets loaded. Neither AT&T nor Verizon has mid-band spectrum yet, so T-Mobile has a customer pleasing speed advantage. (There is almost no advantage to 300 Mbps vs 50 Mbps, but customers love it.)

You can buy the phone on Jan 15 through T-Mobile, which will give you $13 off a $60-$80/month plans. If you don't need much data - most of us these days - you can use the phone on the $20/month prepaid 2 gig plan.

OnePlus will sell you the phone, unlocked, with a $30 discount if you sign up for its mailing list by Jan 15. Apparently, you also get a $50 pair of wireless earbuds, although the website wasn't clear.

Farooq Khan and Jerry Pi's 2011! paper on 5G

Ted Rappaport's 2013 paper, "Millimeter Wave Mobile Communications for 5G Cellular: It Will Work!" brought industry focus to 5G but Ted has pointed me to the earlier work at Samsung. Farooq Khan and Jerry Pi wrote Millimeter Wave Mobile Broadband back in 2011. Until the Samsung and Rappaport work, almost everyone assumed mmWave was impractical for mobile.

Now, every iPhone 12 sold in the U.S. can connect to Verizon's mmWave network, often at a true gigabit, That's three or four times the performance of mid-band 5G from T-Mobile.

Verizon is also now confident most of the problems with mmWave fixed service have been solved with new chips. 70% of new customers self-install.

Khan's new startup, Exium, offers highly sophisticated cloud-based network security.

Broadcom's Wi-Fi 6E at 6 GHz is here

Vijay Nagarian has every right to crow about Broadcom's new Wi-Fi 6, which just passed FCC inspection. It more than doubles effective Wi-Fi capacity, especially when using many antennas. Pai's decision to open the spectrum is one of the most important moves in the last decade. Other nations are now copying it. 

He writes

Wi-Fi 6E: Ready for the road less traveled

Broadcom’s BCM4389 is world’s first FCC-certified Wi-Fi 6E chip
On December 7, 2020, the Federal Communications Commission approved Broadcom's BCM4389 chip as the world’s first ever Wi-Fi device to operate in the 6 GHz band. It is a historic milestone for the Wi-Fi industry. It is also a gratifying moment for Broadcom. Let me explain.

The culmination of a historic FCC decision
Back in April, the FCC announced that 1200 MHz of pristine spectrum in the 6 GHz band was being earmarked for unlicensed access. This was a once-in-25-years type of technology milestone that instantly tripled the available spectrum for Wi-Fi. With this spectrum, you will get multi-gigabit Wi-Fi into your palms — on your mobile devices. With all the Wi-Fi social distancing, this spectrum also delivers ultra-low latency of two milliseconds or so — a performance metric that is supremely critical for future Wi-Fi experiences including AR and VR. ...

With this week's certification of Broadcom's BCM4389 smartphone chip, the FCC closed the loop on this incredible 6 GHz vision. The authorization to operate in this new band signals the advent of the Wi-Fi space age. It is a harbinger for things to come in Wi-Fi innovation over the next two decades.

Broadcom claims 2 millisecond latency, a tenth of the latency on 5G (as deployed) or cable modems.

 

Are 20% of Comcast Gigabit Homes Actually Not Gigabit?

Tyler Cooper of BroadbandNow checked claims of gigabit service from the FCC. He founded that the carriers did not actually sell "gigabit" to a quarter of the claimed homes. Only 56% of addresses listed as "gigabit" could be served at over 900 Mbps.  I reviewed the findings with him. For certainty, more than 75 addresses need to be tested but his methods were sensible. 

Joe Biden wants to spend $20B to bring broadband to unserved rural areas and others in DC are talking $50-80 billion. Given that the recent FCC auction promises to bring 100 Mbps to about 98% of the country, that's a mistake - unless all the data we have being used is mistaken.

95% of the kids without connections could have one if the money is there. Comcast and Chicago are connecting all the kids for ~$10/month.  Charter, T-Mobile, Cox, Verizon, and AT&T have similar programs. This is a "just do it."

5.5G Comes After 5G. 6G is a decade away

Wang Tao of Huawei believes major improvements in 5G are needed as quickly as possible and far ahead of 6G fever dreams. He proposes

• UCBC, to focus on the construction of uplink capabilities, which will be important for industrial IoT. The uplink proposed in the 5G standard is not sufficient for many indoor uses.
• RTBC, focusing on the construction of broadband real-time interaction capabilities
• HCS scenarios, focusing on the construction of capabilities that integrate communication and perception. It would coordinate vehicle and road information

ITU 6G is fascinating to engineers and pr people. Sub-millisecond latency seems exciting until you think of the obstacles to wide deployment and unproven use cases.

5 US Net Giants $7,000,000,000,000 Trillion

Decent people lead Google, Facebook, and the other giants. They are very smart and hard-working. They are no more greedy than anyone else. However, corporate leaders in America put shareholders first. That does not always serve users and the public interest.

Seven trillion dollars of corporate power is unprecedented in my lifetime. These five companies are worth over three times as much as the top twenty-eight telcos across the world (below.) I believe each is now spending over $100 million/year for influence.

Consider a thought experiment. Would the world be better off if the giants were broken into smaller parts, say worth up to $500 billion? 

Capitalism works best with strong competition. If Instagram, Whatsapp, and Facebook how to contend with each other, they would be more innovative. One might even offer a service that didn't abuse your privacy.

Verizon's 25-50 ms "Mobile Edge" runs at 4G latency

Nicki Palmer, Verizon's highly respected Chief Network Officer, spoke of 10 ms latency for 5G Edge. "We have architecture up and running in New York City and we are seeing sub-10-millisecond latency right there as we continue to test," she said in May 2019. Sue Marek reports, "The latency obtained through the company's edge computing test in Houston were 15 ms or half of what's available on Verizon's LTE network." (Verizon 4G often is 30 ms or less, although 4G on many nets should be considered 35-50 ms.)

"Thierry Sender, director of edge computing can guarantee customers latency of between 25 to 50 milliseconds," Sue Marek reports. WTF?

Sender's comment implies has abandoned low latency Edge. It still is adding servers, looking to rent them out to Amazon and (they hope) gaming companies.

Carmakers' discredited spectrum claim

Harold Feld destroyed the carmakers' claim they need 75 MHz of dedicated spectrum for safety. Ajit Pai and a unanimous FCC decided to return 45 MHz to public and unlicensed use. The remaining 30 MHz is more than enough for safety needs. The battle now is whether the automakers get more spectrum to send you commercials and possibly to track you. Congressman Pete DeFazio wants to confuse and delay things. He has now asked the GAO to find a way to bring back the discredited safety arguments. (below)

Harold is the most important telecom consumer advocate and did an excellent job explaining this clearly. He writes at Techdirt

For the Auto Industry, It’s About the Money -- Not Saving Lives

Lobbyists have pressed the “safety band” argument consistently, while acting offended whenever someone points out that 30 MHz leaves them plenty of spectrum for actual highway safety uses if the industry just drops the commercial aspect. Of course, the auto industry says it’s “not about the money.” The industry claims it just expects even more awesome safety features at some indefinite time in the future and therefore requires all 75 MHz of spectrum for when that magical day arrives. In the meantime, though, the auto industry argues it might as well use the extra 45 MHz of spectrum for collecting people’s personal driving information and serving them personal ads -- solely in the name of efficiency, of course. 

For the last four years, the auto industry has refused a non-commercial condition on a band that the industry itself claims is strictly for safety.

Politicians lie, often stupidly. That won't change when Trump leaves town.
