The Battle Between LTE and Wi-Fi May Have Left LTE-U Out In the Cold (networkworld.com)

alphadogg quotes a report from Networkworld: After more than a year of rancor over whether it would hurt Wi-Fi, a technology that lets LTE networks use unlicensed spectrum may have already missed its window of opportunity. LTE-Unlicensed is designed to improve cellular service by tapping into some of the frequencies used by Wi-Fi and other unlicensed technologies. But almost as soon as LTE-U was proposed in late 2014, Wi-Fi supporters pounced. They charged that it would drown out Wi-Fi signals because LTE didn't know how to make room for other users. Now carriers may be getting ready to bypass LTE-U altogether in favor of another system, called LAA (Licensed Assisted Access), that does the same thing but with additional protections for Wi-Fi. The LAA standard is complete, and products are expected to start shipping later this year.

    Nope. Just economics. Basic economic science. Educate yourself about the Tragedy of the Commons, for starters. It's exactly what it's about here.

    Was I the only one left thinking this is a good thing, despite the article seeming to nudge towards the opposite?

    A new standard came along, some people pointed out a problem with it so it wasn't adopted and now a better standard has come along which is unaffected by those problems but retains the original benefits.

    Ermmm, what's the problem?

    That's completely wrong on LTE-U. Part of the problem with the standard is that while the data channel is over the unlicensed bands the control channel is over licensed spectrum. Only companies who have licensed spectrum could have ever used LTE-U. I'm still looking at how LAA works, but LTE-U is a technology that only cell phone companies could use. Perhaps you are thinking about one of the other potential standards like MuLTEfire.

    Actually the electromagnetic spectrum is infinite, at least in theory
    it could get a bit hazardous if we start using X=rays and gamma rays though.
