    Tesla was working with electromagnetic fields which is a short step away, if at all, from radio wave propagation. The fact that he didn't use today's accepted terminology does not detract from his accomplishments. Even the patent office did not know those terms! Semantics, pure and simple.

    Sure, Tesla didn't know what he had discovered/invented and neither did anyone else because it was virgin territory. The operator here is the word "invention" where Tesla didn't know or didn't have the terminology to define/explain the phenomena but neither did anyone else. There are no doubt other "inventions" that would fail the test now as to what was acceptable then even bearing the fact that nobody knew what they had discovered as far as fully and adequately defining it is concerned.

    Therefore, in retrospect we can conclude that Tesla "invented" radio apart from communication and if anyone wants to be convinced of it, read the books referenced in previous posts. On the other hand, equally inventing was Marconi but what he invented was radio communication. Tesla was more into radio transmission of electrical power and actually experimented with radiation and was equally in the dark as to what he had discovered. Furthermore, he realized that radiation was something he could not understand and stopped all experimentation with radiation because of its potential for damaging the human body.

    Stubblefield also invented radio but because it was more a matter of electromagnetic fields and not the propagation of radio waves, he is attributed the "invention" of Radio Broadcasting and this is partially because his communications were one-way, not two-way. However, much of what was being done in radio was gauged alongside the telegraph as far as communication was concerned. Bell's telephone was not only able to do two-way communication, it was able to do both sides of the conversation at the same time. This means that the whole communications scene was not so simple, after all.

    You have to give it to Marconi like that historical piece said: He took what others had done and were doing and he put it all together into a practical and successful method of radio communications. The priest in Brazil and Stubblefield, however, invented systems that used voice communication and this sets them apart from those who merely used coherers, decoherers, inkers and relays to operate other apparatus. Tesla does not take anything away from Marconi. In fact, both discovered ways of using radio but Tesla used it for power transfer and is more famous for phase manipulation while Marconi refined all the then extant technology into a viable communication system.

    The world has survived both Marconi AND Tesla. :)

    Wireless does not necessarily equal 'RF'. For example my IR remote control is 'wireless' but is NOT 'RF'

    No, it wasn't semantics. You need to go look at the patent claims, which are very clear that he was invoking a different (and incorrect) mechanism of propagation for his invention of wireless. He wasn't 'suggesting' an explanation. He was making it a requirement of the invention, through these claims. No one put a gun to his head to put that 'air conductor' language in the claims.

    Tesla saw his 'wireless' Tesla Coil lightning and assumed the air was conducting, and that as you got far enough away, the 'light' in lightning disappeared, but the conductive part did not. He was simply incorrect. And paid the price.

    There is no 'air conductor'.

    The reason he was rejected as the inventor of RF wireless--radio--IN HIS TIME was exactly because of these claims in his patents. They were not for anything like RF.

    No one brushed him off. He was just wrong.

    The Brits equate Wireless with Radio. So do I. Perhaps we are talking about the same thing, after all...

    However, the patent office revisited the patent claims later and further defined the terms. This is why Tesla did not get recognition for the discovery of radio since it conflicted with Marconi's claims. Reading the history of later patent claims shows this.

    The radio amateur in this video congratulates everyone on Radio Day.
    And Gulyemo Marconi was ... just a capitalist who loves money and fame.
    Do you love money and fame? Me not. )))

    An important element in this is the thinking about the ether in the day, treating it as a physical entity that could not be defined, sensed or seen.

    It's like the definition of the Atom in that we have electron microscopes but it cannot see the atom. Therefore, theories came around to explain the atom and one of my friends with a Master's in Physics and Electronics told me that Atomic Theory is a theory because it cannot be seen but is explained by mathematics. He said the theory works mathematically and until another workable theory comes along, they are going with it. Therefore, until another good theory came along, the then theory of electromagnetic waves, they used the term Ether. This I have no doubt fogged the issue and just like the old idea that there is no such thing as perpetual motion, it was a moot subject, but in this case, it all centers on the definition of Perpetual Motion, doesn't it"

    In retrospect, we are all experts and some of us are truly geniuses... :p

    I have to give some comment to the video. For those who do not speak Russian as well as I do.)))
    This is a humorous video.
    Assistant Popov asks: Do you want to connect with Moscow?
    Popov answers: Why? I already know what they will say to me from Moscow.
    I'm curious about what will be said about my invention in New York.
    From New York speaks " the voice of America":
    We have just been informed that some Russian scientist Alexander Popov has finally invented Radio!

    And if seriously - in Russia is really May 7 - Radio Day!

    See page 51 of...

    Tesla wasn't talking about 'ether'--he was specific about air, and ground, conductors.

    No 'ether' shows up in his patents.

    Still struggling with terminology? In the day when Tesla was dealing with man-made lightning, they also did not use ether in the sense of radio propagation. IT WAS ALL NEW TO THEM...

    I have read the books about Tesla. Have you read those books? Do you think it would be a waste of time? Have you only read what was written at the time that in retrospect has to be further defined?

    I have read the books. Tesla was all about experimentation and theory based on what they knew at that time. Edison hired him and Tesla solved a problem that Edison had worked on for years and Tesla did it in three weeks...! And when Edison would not pay him what he promised saying it was just a joke, Tesla quit and went to dig ditches. That was where Westinghouse found him and got him to design the Niagara Falls power plant and the generators are working yet today. Marconi could not have done that. But Marconi wrapped up the accumulated wisdom of the day relating to radio and "invented" a radio communication system.

    What else needs to be said? This is what history tells us. No need to redefine history, is there?

    No,

    I wasn't struggling with anything.

    The facts are apparent to anyone who cares to view them. I just provided you with the easy access. You can look at the patent claims yourself. Please do.

    The fact is that Tesla, himself, didn't, and didn't claim to, invent 'radio'.

    Bright, weird, inventive, dysfunctional, and odd fellow, but not the inventor of radio.
