    There are some drone enthusiasts at work and one of them told me he has a drone which you can program GPS waypoints into and it will go off and fly to each waypoint and return with no input from him once it's on it's way - I think he said it has a range of 10 miles.

    I also know a drone instructor who certifies people to fly drones commercially if anyone wants any serious questions answered.
    I thought that would be the case.

    You would of thought the gov would set some sort of restriction on the use of certain frequencies. If they made it so that the drones used only certain frequencies they can be independently shut down without affecting other devices.

    If you look at the wireless spectrum there's no spare space anywhere in the higher reaches that you need for decent through put, baud rate is directly proportional to frequency (I can't remember the equation though)

    Is the correct answer. Anything else, even a BB gun will get you into big trouble.

    Are they using Wi-Fi for the control aspects then? I thought they only used that for the data / image stream?

    I don't know, I thought so as it seems weird to have multiple radios in one drone, I could look it up, but I'm not that interested.
    But, you would be better off using a lower frequency if you could because for the same output power a low frequency signal goes a lot further, but the data rate drops.

    Are you making it up instead?

    No, merely repeating what I've been told, I don't like drones, but I seem to know quite a few people who do.
    Unfortunately I do have to know about wireless data comms for my job - I wish I didn't because they're so unreliable due to the pathetic outputs that ate legally allowed, if you compare them with mobile phones, output power of WiFi is laughable, if something is going to microwave your brain, it's your phone, not your WiFi.

    I wonder if anyone has made a drone controlled and sending data back by 4G, apart from the average 60ms delay that all 4G networks have, it'd be really good.

    Google and you shall find

    https://botlink.com/4g-lte-cellular-...ne-control-xrd

    That really is quite scary from a being spied-on or weapon delivery point of view.

    Used to have a 1/2/3g mobile phone jammer. I got it from a friend in Israel. Actually I've still got it, but not much use these days. But when I was working in London it gave me a sense of deep joy to be able to shut up the shouty morons on trains and in pubs/cafes. It was basically about the size of a box of Swan Vestas, with three small stubby arials on the top, and an on/off button. Had a range of about 30 feet when in a bag or pocket.

    Effing Drones, and other rc objects that have cameras on them....They’re killing off a hobby that I’ve been involved in for over 45 years...lawmakers are getting serious with regard to legislation to absolutely regulation model flying out of existence. This being due to 2 reasons...
    1. Irresponsible drone fliers who will continue to ignore any regulations imposed upon law abiding modellers
    2. Monetizing the low level airspace for Amazon and other drone ‘delivery’ companies.
    Pissed off isn’t sufficient to describe how I feel about this

    something like this, but in reverse (bonus points if you chase the drone shooting fireworks out of your butt)
