Samsung testing 5G wireless tech capable of downloading entire HD movies in seconds

“South Korean tech giant Samsung says it has developed a wireless transmission standard hundreds of times faster than today’s 4G LTE, one that could see users downloading entire movies in seconds,” AppleInsider reports.

“Samsung on Sunday announced that it had developed a core component of its 5G network by solving a problem that has stymied the wireless industry, Yonhap News reported,” AppleInsider reports. “Using the 28GHz waveband, Samsung says it has achieved download and upload speeds of tens of gigabits per second (Gbps). Current 4G LTE networks top out at around 75 megabits (Mbps). ”

AppleInsider reports, “In practice, that speed would allow wireless users to download a full HD movie in seconds… Samsung used 64 antenna elements in order to accomplish the high-speed data transfer, and said the company expects that it can commercialize the technology by 2020… Samsung is not alone in developing next generation wireless technology, nor is its recently announced demonstration the fastest of its kind. NTT DoCoMo in February announced that it had successfully conducted a 10Gbps wireless test in Japan last year using the 11GHz band.”

  1. 64 antenna elements! No wonder Samsung keeps pushing their phones to ever more user-unfriendly hand brick sizes. They need the room. Remember the old Motorola cell phones of the ’80s? Welcome them back in the form of Samdung Phalaxy hand bricks of the 20-teens.

    1. I’m envisioning something literally the size of a BRICK with the Samsung logo on it, 64 wire antennas sticking out of the top of the thing and flopping over like a fiber optic fountain, or like wild hippy hair. Wave it around to amuse the kids. Scare the cat with it. Watch the dog attack it and shake it around in its teeth to break its neck. Fun for the whole family! Samsung.

  2. Until 2020, it’s just vapor. The real news today is that Samsung makes cheap knock-off crap and gets away with it. If Apple tried this, it would be all over the news. Well, at least NYT and WSJ.

  3. 5G is not an invention or technology. Rather, it is a generation jump compromised of several technologies and infrastructure. If you remember 4G/LTE/HSPA+ chaos. That’s why Apple didn’t adopt the so-called generation because it was spotty at best when first introduced. 2020 is perhaps possible but then they have to roll out the 5G infrastructure. More antennas!

    1. And it’s already showing competing technologies for 5G. If we have 5G by 2020, I’d be shocked (real, true 10GB/sec load times, not some marketing 5G).

      Wireless providers are already taking years and investing billions of dollars to roll out LTE, so now they’re going to jump on additional billions for 5G in 7 years? I doubt it.

  4. First, Samsung *demonstrated* 1 Gbps (not GBps). They did not demonstrate 10s of Gbps. That’s just the theoretical limit of the waveform.

    Second, it is based upon 32 x 32 MIMO. Thus the system needs to differentiate at least 32 *different* paths in order to achieve those data rates. Cell phone towers will need to be a minimum of three sets of 32 antennas. That will be costly.

    Third, it is going to be a HUGE design challenge (but not impossible) to implement 32 distinct antennas in a cell phone. {Maybe that’s why Samsung’s phones are getting larger and larger and larger — a 15″ diagonal screen cell phone could realistically have 32 distinct antennas.)

    Fourth, the system is implemented at 28 GHz which has over 300 times the atmospheric losses as the 800 MHz to 1.9 GHz frequencies of today’s cell phones. I just can’t wait to have to say, “Damn, my connection dropped back to LTE-A because it’s raining!”

    Fifth, LTE-A already supports speeds up to 1 Gbps download and 500 Mbps upload. There have already been a few scattered implementations and several major carriers will be rolling out LTE-A in late 2013 and 2014. LTE-A will get a LOT of maturity between 2014 and 2020. LTE-A at 1 Gbps will be an old, tried and true implementation long before 2020.

    Sixth, there are several competing standards for “5G”. Samsung’s implementation is just one of those many. If I had to lay a bet at the moment, I’d choose the 3GPP committee’s evolving waveform. They’ve had the widest release and most accepted version (3G UMTS/HSPA, LTE, LTE-A) of the last few generations. I see no reason for their string to end.

    Could some part of Samsung’s demonstrated implementation end up in the “5G” standard? Certainly. Will the “5G” standard be 100% based upon Samsung’s implementation? Absolutely not.

    1. Shadowself has pointed out a number of significant issues. The most significant of them as far as I’m concerned is the use of 28GHz. At such extremely high frequencies, radio waves behave more like light than conventional RF and it’s very easy to disrupt the signal.

      It’s hard to imagine how this technology could be of practical use in real world situations. It’s more of a laboratory experiment to demonstrate a concept ( and impress journalists who don’t understand such things ).

      Having said that, I was involved in some very early BlueTooth demonstrations about twenty years ago and they were ridiculously unreliable and virtually unusable – we resorted to faking the results for a TV show. I was convinced at the time that BlueTooth was unlikely to ever work reliably, but Samsung are now talking about working at ten times that frequency.

    2. Thank you Shadowself for providing seriously great information. There is very little of it around here regarding mobile technology. I’ve been doing my best to post what meagre data I can find and comprehend. It looks like you’ve got some solid training and understanding of the field! Please stick around.

      [For newbies: LTE-A = LTE Advanced, which I cover in further detail below…]
