back to article Euro mobile standards chiefs eye tiny beauty: It's the KEY to 5G

The European Telecommunications Standards Institute (ETSI), which sets the standards for mobile comms, has just started work on five specifications for millimetre Wave Transmission – the 30GHz to 300GHz range. The new Industry Specification Group on millimetre Wave Transmission (ISG mWT) held its first meeting last week and …

    ask the HAMS

    Apparently this body is looking for something the amateur radio community is already actively researching.

    Several experiments are regularly undertaken with amateur tv connections in the 24ghz spectrum.

    Biggest issue with these high frequencies will be influences from the weather (humidity etc.).

    Even a wet pane of glass will constitute a 10DB attenuator.

    73!

    Large numbers of small cells

    Vernor Vinge's "localisers", anyone?

    WTF?

    Am I being stupid here?

    Loads of tiny cells controlled by lower-frequency super-cells? Why not just connect the end-user devices to the super-cell?

      Because 30GHz and up only works over short distances and gets wiped out by rain.

      Presumably the supercells will have wave guides so that they can reuse the standard spectrum more efficiently

        Ahh. That makes sense

    Deja vu all over again

    Back nearly 20 years ago while working for Motorola, I chanced upon an internal noticeboard advertising for RF engineers asking for people wanting to work on "3G" at "60GHz"....

    If that's the frequency range 5G is one, I think LTE has a very long lifetime, as does Wifi :-)

    Roofs

    house roofs to High Altitude platforms.

    It's useless for Mobile, even if every lamp post had it. Behaves too much like IR or light links.

    Nothing to do with 5G, if anyone ever decides what 5G actually is.

    Can't see such high frequencies being very useful

    Line of sight is required, so they don't go around buildings and even the leaves of trees will kill the signal (try to aim your satellite dish through leaves and you'll see what I mean, and that's at lower frequencies)

    Without a use case for gigabit links to mobile devices it seems like they're putting the cart ahead of the horse a bit. Not saying we'll NEVER need gigabit links to mobile devices, but maybe a less aggressive version of 5G or further evolution of LTE would be more productive at this point in time.

    (Waiting for the inevitable downvotes from the "technology must march on whether it is needed or not" and "if you build it, the use cases will come" crowd)

    ITU working away on mm wave

    So the ITU-R Study Group 5 working party on IMT systems is meeting this week in New Zealand, and future use of mm wave for cellular use (above 6 GHz) is on the agenda. Will be interesting to see what comes out after next Wednesday and heads towards to World Radio Conference at the end of the year in Geneva.
