Belfort Wikipedia
Gets ARCEP permission to test. Ted Rappaport at NYU has convinced the industry that high-frequency, millimeter wave wireless can work. But many questions remain. What are the effects of walls, windows, rain, and distance? We have only partial answers.

France Telecom/Orange intends to find out. They just receive approval for a year's worth of testing in the ancient city of Belfort. Much of the testing to date has been in Manhattan, Brooklyn and other highrise areas. Belfort is ideal for testing low-rise and suburban regions.

Millimeter wave is newer technology that's getting much of the early 5G news flow. It remains unclear in what areas it will be the best choice. In urban areas, the French are proving you can get enormous capacity at minimal cost by turning on a second SSID in every home gateway. MIMO is ready to go from 2 antennas to 8; Henry Samueli of Broadcom is working on 50 antennas. UCSD has a prototype with 256 antennas. Massive MIMO prefers millimeter wave for the smaller antennas but  you can fit many medium-sized antennas on buildings and even some towers. 

No good engineer doubts gigabit wireless is coming.

Thanks to TelecomTV for pointing me to this story.

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 US#2/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 6 days sold 300,000 5G Mate 20s. Delivery begins on 8/16. 

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%. 

5G phones spotted from Sharp and Sony

NTT DOCOMO will begin "pre-commercial service Sept 20 with over 100 live bases. Officially, the commercial start is 2020.

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.
