Nokia Networks Demonstrates 5G Mobile Speeds Running At 10Gbps Via 73GHz 55

Mark.JUK writes The Brooklyn 5G Summit appears to have provided a platform for Nokia Networks to demo a prototype of their future 5G (5th Generation) mobile network technology, which they claim can already deliver data speeds of 10 Gigabits per second using millimeter Wave (mmW) frequency bands of 73GHz. The demo also made use of 2×2 Multiple-Input and Multiple-Output (MIMO) links via single carrier Null Cyclic Prefix modulation and frame size of 100 micro seconds, although crucially no information about the distance of this demo transmission has been released and at 73GHz you'd need quite a dense network in order to overcome the problems of high frequency signal coverage and penetration.

    10 gigabits per second! Sweet! I can run through my entire Verizon monthly 2 gig allottment in under 2 seconds, and run up $10 a second per gig in overage!

      Your calculations are off by a factor of 8. You'd get whole 16 seconds, not 2, you ungrateful customer you!

    • My thoughts exactly. The bandwidth caps are so low and the prices are so high that honestly I'd be happier with 2G speeds and unlimited data. By all means, make it slow as shit... I just don't want to worry about the data. And if I have to worry about it then the last thing I need is for it to be so fast that I can blow through my data budget in an eye blink.

      Until the business model changes radically in cellular data, we can't have faster speeds. The costs are already unreasonable at existing speeds.

      • That's one of the reasons that I like T-Mobile. I can go over my data allotment, and all they do is throttle me.

    • They carriers need to offer reasonable rates for data.
      I would be happy to drop my cable internet for a wireless option, but it isn't economical.

      Heh heh yeah. I generate 2-3 GB a week in skydiving videos. Last week the municipal internet guys came around and ran gigabit fibers to my house. I started my upload for a long high pull video and it was uploaded before I could finish typing the description. I'm pretty sure my home internet is now faster than any place I've ever worked. In fact, I'm pretty sure my home internet is now faster than the local network speed of any place I've ever worked.
    • Funny, but completely misses the point. The real news here is that mobile data speeds are going to start competing with traditional wired home ISPs in the near future. Verizon has already stated they are not laying any more [expensive] new fiber cables to focus on their mobile services. You can read between the lines. As for pricing, the market will figure that out for sure. Consider this very real possibility: what if a mobile provider had a 5G [or next-gen] cell tower in a suburban area and offered everyo

    Shouldn't this be named "1/25 of an inch Wave", or "OTFOAIW"?

  • this has any appreciable range, and instead of reserving the band for cellular towers, they put this stuff in consumer available gear, we can all interconnect wirelessly and tell comcast, verizon, et-al to go to hell.

    • Absorption by water molecules really picks up above about 6 GHz. This limits the practical range for high frequency signals.

    faster cellular networks aren't all that interesting. It will take forever for them to be deployed, and

    Now give me an 802.11ZZZ or something that can do just 20Mb/s or so at 10 miles NLOS with non-directional antennas, and you've got something useful.

      And, by necessity of physics, massively wasteful of rf frequency. Not sure why you need this, also?

    Over what distance? And with what power requirements? How many concurrent users at what bandwidth?

  • I'm going to take your "2×2 MIMO, single carrier Null Cyclic Prefix modulation" and trump it with my ingenious "3×3 MIMO, double carrier Pigeon"! Do your worst Nokia!

      That's not all that frequency does! Reading this [springer.com], "Low Intensity Electromagnetic Irradiation with 70.6 and 73 GHz Frequencies Affects Escherichia coli Growth and Changes Water Properties". So there are probably many unknown side effects that will start showing once this is in offices all over the place.

        Abstract

        Introduction. The interaction of mobile phone radio-frequency electromagnetic radiation (RF-EMR) with the brain is a serious concern of our society.

        Objective. We evaluated the effect of RF-EMR from mobile phones on passive avoidance behaviour and hippocampal morphology in rats.

        Materials and methods. Healthy male albino Wistar rats were exposed to RF-EMR by giving 50 missed calls (within 1 hour) per day for 4 weeks, keeping a GSM (0.9 GHz/1.8 GHz) mobile phone in vibratory mode (no ring tone) in the cage. After the experimental period, passive avoidance behaviour and hippocampal morphology were studied.

        Results. Passive avoidance behaviour was significantly affected in mobile phone RF-EMR-exposed rats demonstrated as shorter entrance latency to the dark compartment when compared to the control rats. Marked morphological changes were also observed in the CA3 region of the hippocampus of the mobile phone-exposed rats in comparison to the control rats.

        Conclusion. Mobile phone RF-EMR exposure significantly altered the passive avoidance behaviour and hippocampal morphology in rats.

  • I would take even 4G bandwidth anytime, if it could match the speed of ADSL, and I mean latency. I'm stuck with ADSL, fiber is in 50 m away, but none is going to dig it here.

    I hope someone could standardize realistic measure of speed, that takes account the latency. It's really important when browsing, as usual webpage these days contact to so many different sources.

  • 1) How much of the available frequency does this chew up, and 2) if it is directional, how tight is the beam?

    These are important considerations for things like mobile-service, which is typically not "narrow-beam."

    If the weather issue can be worked out, I see this as being useful for "fixed-wireless" applications, such as broadcast-television (think "cable TV without the cable and without the dish") and point-to-point communications (think "wireless U-Verse").

    Subject to downtime due to weather-related interf

    • Higher frequencies are easier to form into directed beams dynamically with phased arrays. Not that I have any indication that Nokia has done this.

  • I don't see much point to be honest.

    For a start, telcos these days have very stringent bandwidth caps. For an example, here in Singapore, a 2 year mobile data plan with 12GB/month costs ~USD 200/month. Other than light usage (e.g. browsing, bit of skype and youtube), you can't do much.

    And what about power consumption ? how fast can it drain your phone battery ?
