Work Continues on 5G -- Shame Nobody is Sure what It's for Yet

5G is – surprise, surprise – dominating this year's Mobile World Congress [MWC] as more emphasis is heaped on how non-telco vertical sectors can use the fledgling technology.

Unlike 4G or any previous cellular generation, 5G aims to cover a wider set of use cases from the outset: not only enhanced mobile broadband, but also massive machine-type communications and ultra-reliable low latency applications. The new capabilities could broaden cellular-based networks to potential new users, particularly in vertical industries from automotive to factory automation.

To achieve that, the telecom sector is seeking input from other verticals on 5G use cases and technical requirements that will help them to shape standards. During the last 18 months to two years, the telecom industry has been urging vertical sectors to get involved and there are now signs of engagement.

    Like 10ms ping to my game servers like I have now on cable broadband?

    How is this magical 5G going to get around satellite distance lag? Speed up wave propagation? (joke)

    Best ping to IP addresses from my iPhone over AT&T 4G/LTE is like 55-75ms now.

    It would be nice, if it works, but I'm not holding my breath.

    ultra-reliable low latency applications

    One totally stereotypical way to work around fading and interference is to ruin low latency to increase reliability. Of course you can trade off higher SNR. Possibly they're not really improving or changing much just slightly adjusting the proposed tradeoff point to have slightly lower latency at slightly higher power / lower noise / wider bandwidth / higher bit error rate / higher battery power use for the modem. Since the claim ultra reliable (which has no technical meaning) then they're probably not messing with the BER or perhaps they're doing something diabolical like banning raw UDP packets in favor of TCP error corrected streams only.

      So in scientific terms, this would be a vapor kluge of a workaround for a clusterfuck.

          I think we've all worked there in spirit, although technically that's from Scoggin's book, isn't it? If not, it should have been.

      no, i'd say its totally a stereotypical way that regular people see wireless phone network connectivity

      he's a consumer with a consumer view. gaming doesnt mean IT expert -- it used to mean the guy had a chance to be a whiz kid, but young male gamers are now among the most clueless of users there are, instead of their moms as it used to be when they first got onto AOL.

      they might be able to show you how to install free apps or something, but they wont be fixing anyones computer. infecting it yes, fixing it no.

      then theyll blame poor optimization and coil whine and high ping times in no particular order

    Please note, your average cellphone isn't a satellite phone. It's getting a signal from a ground based tower. Otherwise, your ping would likely be averaging somewhere between 700ms and 1500ms as most satellites aren't low earth orbit.

      Wat???

      That tower interfaces via microwave relay, which is often satcom-based. Why the fuck would we need "communications satellites" if all we need is fucking towers?
