Possible Correction: AT&T Says "All-Fiber," Not Fiber to the Basement and G.fast

If so, my article that AT&T will use 400-700 megabit G.fast to five million is a mistake. AT&T's press release I just read (below) promises "Within 4 years, AT&T will offer its all-fiber Internet access service to at least 12.5 million customer locations, such as residences, home offices and very small businesses." It may well be that the pr people at AT&T don't understand the technology being used and much of the build will in fact be Fiber to the Basement and copper, probably G.fast, to the apartment. But if I may have an error, it's my job to issue a correction.

Mobile: "Huawei Kirin 950 Takes Performance Lead"

Shenzhen 280 wikiopediaMarket for mobile chips disappearing. When Henry Samueli shut down Broadcom's cellular baseband business, I happened to be visiting one of the founders. Many of the 3,000 engineers affected were his friends and the pain was apparent. However, I could see why the decision was necessary. Apple and Samsung dominate the mobile phone business and each made their own chips. Those two companies had growing market share and there just wasn't enough merchant business to sustain the chip vendors. Qualcomm's scale gives them a major advantage and the very efficient Mediatek has also grown.

Huawei, #3 or #4 in cell phone sales, is taking a similar path. Top analyst Linley Gwennap (quote in the headline) is enthusiastic about the new Huawei chip. He believes, "The new chip will outperform both the Snapdragon 810 and the Exynos 7420 on most mobile benchmarks, setting a new bar for smartphone performance."

Spain Leading the West with 15M Fibered Homes Passed (75%)

Flamenco-DancerFT/Orange Spain going to 10M & 14M. Without much publicity, Spain has pulled far ahead of other large nations in fiber homes. The U.S., Italy and France have passed fewer than 25%, Germany and England less than 10%.

2018: More African, Indian Net Users Than Americans

Kai-Krauses-remarkable-true size of africa430The center of the Internet has moved South. Carter Horney of Forward Concepts has just published a Global 4G analysis with a detailed geographical breakdown. His projection for 2018 is 315M smartphone Internet users in India and 317M Africans connected. The U.S. population is 315M, some of them under 4 years old and not connecting to the net. His estimate is close to the 300M in 2017 I projected with Cisco's help http://bit.ly/Africa300M last year. 

These estimates are very rough but the trend is clear. Both India and Africa have over a billion people. $50 smartphones are affordable to hundreds of millions more than are connected today. Carlos Slim told me two years ago that $50 smartphones will connect two billion more people. He's proving right.

2-3 Gigabits Spectrum Unused at Dish, Verizon, Sprint & AT&T (AO)

Detail of Cedalion standing on the shoulders of Orion by Nicolas PoussinDetail of Cedalion standing on the shoulders of Orion by Nicolas PoussinEngineers know this because they stand on the shoulders of giants. Policy people  are too often blinded by the fog of interests. With just the spectrum already allocated, AT&T Blind mice from zhouxuanand Verizon could easily triple their network capacity without breaking the capital budget. The technology is obvious but the change in business models is unlikely. Sprint has remarkable holdings around 2.5GHz. Dish spectrum is totally unused.

There's enough available spectrum to build at least three Verizon-sized networks. The currently allocated but unused spectrum is allowing both AT&T and Verizon to double their wireless capabilities. I wrote this article because <yet another generally very knowledgeable> person just left that doubling out of his predictions. It's commonly overlooked.

My estimate is that spectrum, advanced technology and investment can easily provide a 25x gain many without blowing out capex budgets - if policy is smarter.  The increased costs should be no more than 2% of sales and probably much less.

400M Indians, 50M French Going LoRa. Is LTE Obsolete for IOT

Hedy LaMarrLamarr really was an inventor of spread spectrumPromised: 10 year battery life;, very low power; 15 km reach; 50-meter ground penetration; not stopped by seven walls; doesn't need a spectrum allocation. It's also darned cheap. The performance is a dismal 0.3 kbps to 50 kbps but it still sounds impossible. 

Little chipmaker Semtech seemed to be tilting at windmills until Bouygues turned on Grenoble and Paris. Bouygues plans 20 cities in France by the end of this year. France Telecom responded they will cover "the entire nation" by the end of next year. Now Tata, a $100B conglomerate, announced they will serve 400M people in India's cities. Swisscom and KPN have announcements.

Verizon 2017?: 5-10x Faster 5G M-MIMO

Verizon and Nokia refuse to wait for 2020 for 5G. Massive MIMO promises major speed jumps in the same spectrum. Testing in 2016 for Massive MIMO, beamforming and interference cancellation. Hopes for huge speed boost starting in 2017. Think 64 antennas and 5-10x throughput. Good engineers tell me it's possible but didn't expect it so soon. 

Verizon Ready to Try Massive MIMO and Beamforming

Beginning trials soon would suggest deployment in 2017 if they go well. That's not guaranteed. Lowell McAdam plans "Staying ~two years ahead of competitors in network performance." They are getting ambitious, including going to Alcatel's TWDM PON for 40 gig. "VZ will soon begin market trials of 5G capabilities including 'massive MIMO' (which is when a large number of antennas are packed into a single device) and beam forming (which is when a wireless signal is concentrated on a specific location)."(Paul de Sa) Much more http://bit.ly/5G256Ant

Nokia's Moliin: Massive MIMO/Interference Cancellation is Ready

CTO Hossein Moiin intends to test Antonio Forenza's pCell technology early next year. There have been stadium field trials that went well. Very big improvements are close in wireless. Four world-class engineers were comfortable with the forecast wireless capacity would soon increase 50 times or more.
