BT LTE Coverage Open SIgnal 180Fotis Karonis sees everything before that as "proof of concept." He's Managing Director of Mobile and also IT, where he's advancing Software Enabled Networks. He believes BT will be first in Britain, implying the other British companies will be later. He didn't say the "first commercial" cells in 2020 will be many, so his date doesn't conflict with the 2022-2024 plan for volume mmWave from NTT's Seizo Onoe.

He acknowledges that BT still has a long way to go in LTE deployment. While they claim 99% population coverage with LTE, these maps from Open Signal suggest they are not using a robust measure of actual coverage. The map above is based on tested connections to LTE. Below, the 4G and 3G maps are side by side. Note how many places 3G is working but you can't even get 4G. That's strongly suggestive of either a crowded LTE network or optimistic coverage estimates.  

Karonis is strong on the need for reliability, particularly as BT adds security services as customers.

Stanford Professor Paulraj has been particularly strong on the need for reliability as we become more dependent on telco networks. Everyone agrees that's critical for 5G, but we'll see whether networks are built to that standard.   

In this video interview with Justin Springham of Mobile World at HWMBBF16, Fotis is clearly talking about mmWave as 5G but not Massive MIMO. At that show, I learned that both Softbank Japan and China Mobile on ordering thousands of Massive MIMO cells, getting 3X to 10X capacity improvements with better to follow. I think if he thought about it, he'd include Massive MIMO in "5G," and make clear when he's discussing mmWave exclusively. Here are the video and the two maps.

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%.

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.
