> Eric Xu, current Huawei Chairman, concludes "consumers would find no 'material difference between 5G & LTE'.” Louise 
> Lucas and Nic Fildes,  Financial Times He added, "Since 4G is robust, we don’t see many use cases or applications we 
> need to support with 5G.” 
>
> Last May, I reported similar thoughts from Telefonica CTO Enrico Blanco. In November, DT CTO Bruno Jacobfeuerborn,  
> FT/Orange SVP Arnaud Vamparys, and BT CEO Gavin Patterson chimed in. The politicians & marketers screamed "5G 
> Revolution." The engineers knew better.

> Andrus Anders and Roberto Viola at the EU, as well as Jessica Rosenworcel & Ajit Pai in the U.S., are still lying to 
> themselves and too proud to face their errors.

> Latency:  Ericsson has promised LTE latency of 9 ms in 2018. AT&T's 5G latency is 9-11 ms.
>
> Speed: 4G LTE 2018 is hundreds of megabits, peaking over a gigabit. 90% of 5G on the way is midband, the same 
> hundreds of megabits. Only 10-20% of the first few years will be millimeter wave, often a gigabit.
>
> Applications: 5G's main application around the world will be more capacity, a good thing for telcos. But most of the 
> other claims are b______.

> Connected cars are already on the road, using lidar & radar, not the phone network. Xu points out, “even today we 
> have the technology that can support autonomous driving”.
> The talk of remote surgery is totally ridiculous unless you believe in operating from the beach. The wireless part of 
> the transmission is only a small part of the speed.   From the local connection to the operating room will be 20-50 
> ms. Whether the wireless is 2, 5, or 10 ms. is a minor factor. 
> IoT will rarely require speeds more than 100's of megabits. Most actually is kilobits. If there so many connections 
> that LTE is overwhelmed, a local Wi-Fi or LTE picocell can handle almost everything.
> VR experts tell me they are fine at 10-15 ms.
> Outside the U.S., very little fixed wireless requires 5G speeds. AT&T and Verizon will use mmWave where they don't 
> have decent broadband, about 75% of the country in each case. Nearly everywhere else, the telco covers the whole 
> country with landlines.
> "5G Revolution" is dead. Millimeter wave and Massive MIMO will be crucial to telcos going forward; midband spectrum 
> will be important, running at LTE speeds and really LTE with a minor software tweak and a press release. Until 2018, 
> it was called TD-LTE.

> Verizon's D.C. rep, CTIA, has nonsense claims for 5G, based on 4G applications.
