On whether 5G will come faster"Do it all so much faster than either company could on its own,” Legere said in the release. T-Mobile CTO Neville Ray told MWCT-Mobile Building Out 5G in 30 Cities This Year ...and That’s Just the Start.He also committed to the entire country by 2020. My comment, admittedly snarky, is, "The only way the new T-Mobile could bring 5G faster is to build it in 2017." That would be difficult at this point. It's also unlikely to cover the whole country any earlier than 2020. Tmo VP Technology Karri Kuoppamaki last week emphasized how their 600 MHz spectrum will let them reach the whole country by 2020.
"5G" is not "5G." Much will not be the truly high speeds of millimeter wave. Much of what is now called "5G" is a marketing invention in the last year, including T-Mobile's 600 MHz "5G." Low & mid-band "5G" is the same as 4G LTE with a software tweak (NR - New radio.) Only millimeter wave is much faster than 4G from 2018 equipment. mmWave can be 2-3 times faster than the LTE at 500 meg T-Mobile is rolling out. Verizon and AT&T are using millimeter wave, 28 & 39 GHz. T-Mobile is using 600 MHz & a pr campaign. A year ago, millimeter wave and perhaps Massive MIMO were considered 5G. (See IMT-2020 in standards.) In 2017, lobbyists and marketing people extended the definition of "5G" to anything with a software improvement that does little for speed or capacity. (NR) Corporate run 3GPP expanded the standard. Amazingly few reporters realized that meant most 5G deployments were nothing special. AT&T & Verizon are doing millimeter wave but low and mid-band will be 80% to 90% for at least several years.
Is even the real 5G, millimeter wave, revolutionary? I have quotes rejecting the 5G hype from CEO, CTOs,, or other senior technical people at AT&T, Verizon, British Telecom, Deutsche Telecom, Orange and Telefonica. D.C. has fallen for spin. So have too many reporters. Professor Gerhard Fettweis, the leading expert, told a conference last week. "Autonomous cars will not use 5G because they have to work on all roads. They use radar and LIDAR instead." (Story to come.) VR, AR, and telemedicine are working well today without 5G. Remote surgery only needs 5G if doctors intend to work from the beach. (Ask me if you don't see that.) Nearly all the independent technical people see more and faster broadband as the primary use for 5G for years. That makes 5G important for the industry but definitely not world-changing.
"5G offers more reliability than 4G or LTE" Washington Post. Reliability is planned for 5G URLLC (Ultra Reliable and Low Latency Communications.) The full standard for that isn't expected until late 2019 and wide deployment mostly long after. T-Mobile's nationwide "5G" network does not support URLLC and may never do so, Some engineers are dubious about whether the reliability will be achieved, so firm statements are probably dubious. While 5G may offer more reliability one day, using the present tense is an actual error.
Is 5g required for autonomous cars? The very respectedProfessor Gerhard Fettweis from Dresden last week at a conference said, "Autonomous cars do not need 5G." They work on LIDAR and radar. 5G mmWave will not cover most roads for a decade or more. There will always be places not covered. Autonomous cars have to be able to work without 5G. IEEE has video of the session; I haven't written it up yet. At least one on the panel disagreed. I would recommend checking with an engineer currently active in the field before publishing on the topic. Many policy people are giving false information, mostly because they don't understand.
Is 5G needed for telemedicine or IoT? The answer is probably not, but I don't have time to research and write it right now. Again, much of what's said is simply inaccurate; a newspaper we all respect made an error here.
