    Are you worried about 5G?

      nah im more worried about the computer science essay i have to do on it... (u guys kindof saved me)

      Yes I was going to live in a place but then my parents saw a tower with 5g right behind the house and my dad had so much family that couldn’t have children from living close to these and cancer overall sickness I think if it can affect people’s lives negatively already it’s definitely something or worry about

      Let’s reach 100 subscribers I love you New Zealand has loads of 5g towers and they ZERO problems,also they no cases of corona virus. I bet tanning salons are more harmful than 5g waves.

      I'm some what worried about it since health insurence companys have said that it isn't safe and they wouldn't lie about that since if it does they'll lose money.

    Thank you for making this episode it’s nice to have people talk about things deeply when often these are the things people brush off and don’t think about

    Great episode! Really informative. How long did the research take you? How ever long it was it definitely gave me a much more positive view of 5G. Thank you

    The whole problem is commercialism fuelling disposable technology. As pointed out in this video the attitude is very much: this is the next technology, then there'll be the next technology. That's without any concern for what happens to the technology we already have, and what with climate change and overpopulation, this really needs to change.

    7:25 There is encoding in analog, to an extent. In digital data transmission, you use methods known as 'keying' where a certain parameter of a carrier is set a certain way in response to the input byte. The simplest are amplitude shift keying (ASK), where the loud sound is a 1 and the quiet sound is a 0, or frequency shift keying (FSK) where the high pitch sound is a 1 and the low pitch is a 0. The more common keying now is phase shift keying (PSK), where the waveform is inverted for a 1 vs a 0, as that allows for faster switching rate. You can also encode 2 bits per cycle using 1/4 wave phase keying, or quadrature amplitude keying but that is getting more advanced.
    In analog electronics, the term is 'modulation' and fits into 1 of 5, Amplitude Modulation (AM), Frequency Modulation (FM), Phase Modulation (PM), Ring Modulation (RM), or Pulse-Width Modulation (PWM).
    To break it down, AM and FM is the analog version of ASK and FSK, with the analog compliment of PSK being PM. AM and FM are used to encode a digital audio signal into a radio frequency carrier, PM much less common for analog signals, but some old versions of satellite TV used it. RM is used mostly as an instrument, or in audio engineering, and PWM has many applications, mostly in the realm of power electronics. By increasing the duty-cycle of the square wave, you can determine how much power is being transferred, and you can linearly modify both the voltage and current without depending on resistors or diodes, which have tolerances and thermal voltage variation.

    20:40 4k is 3840x2160, which works out to just shy of 8.3megapixels. This is commonly called UHD. 2k is 1920x1080, or just over 2 megapixels, often called FHD. QHD is 2160x1440, or about 3.1megapixels.
    What is technically HD is 1280x720, or 920kilopixels. That means 4K more than 8x the number of pixels as HD. You also have SD, or standard definition which is 640x480, or classically 480 scan lines. This comes from the days of CRT, and when digitized gives about 300kilopixels.
    Remember that each pixel of each frame requires 3 bytes of data. That means HD takes 2.76MB, FHD takes around 6MB, QHD takes about 9.3MB, and UHD takes a whopping 25 MB per frame. You should expect no less than 30fps on most displays, so that gives 750MB per second for 30fps uncompressed UHD, more than a gigabit connection could handle, which is 125MB/s. 60fps would require 1.5GB/s. You can get to streaming 60fps UHD video on a gigabit connection using video compression, the most common being mp4. That can reduce file size to about 10% before it stars to become unwatchable. That can get you down to 150MB/s, right at the upper end of what's possible on a gigabit connection.

    The only issue I am aware of regarding 5g is how it may interfere with aircraft radar altimeters. In short, planes can usually land up bad weather using VHF and UHF radio guidance, or using the GPS equivalent. These are called ILS and LPV approaches respectively. These don't interfere with 5g. However, planes also use EHF radar to tell it's altitude if you want to land in worse weather than that.
    A typical ILS is called Category 1, and allows you to descend to 200 feet above the runway. You don't need a radar altimeter for this, as the ground guidance is accurate enough down to 200 feet. With a Category 2 ILS, you can descend to 100 feet, and Category 3 has no minimums, only forward visibility restrictions. Category 3(c) is the worst, indicating zero ceilings and zero forward visibility. As I understand it, all planes doing a category 3 approach need 2 redundant radar altimeters, and category 2 approaches need just 1 radar altimeter. These radar altimeters take up the same frequency domain as 5g, meaning the plane can mistake a 5g transmission for an echo, leading to erroneous readings. Worst case, something like Alitalia 404. Realitically, the pilots would go around, report instrument error, and maybe divert to an airport with better weather. All you need is 200 feet to do a regular Category 1 approach.

    The 4s scandal is less likely to be a problem because there will be so many antennas all over the place. 5G also has beamforming so it can bounce the signals off obstacles around you

    One problem with 5G is that the demand will likely be higher than the technology can cope with, in the same way as 4G is packed. 5G is a huge leap, but the demand may be much bigger

    You really need to research information properly.. I understand you may not be experts in IT or wireless networking, but this episode was riddled with misinformation. Genuinely disappointed over this guys People trust your opinions as fact and that means you should do you homework properly.
