Copying some of the FAQ from part 1: "Can I use this in my ___?": Yes, although I did record these sounds and could say others aren't allowed to use them, I think saying I own the sounds of radio interference would be a little silly, no? "How do you record these sounds?": You will need some kind of audio equipment that is susceptible to the phone's RF interference. That can include old headphones, speakers or a single speaker, sound systems, microphones, amplifiers, TVs or radios could work depending on the age, guitar amps work too. If you are capable of building your own electronics, there are also ways to make devices that are sensitive to and can capture RF interference. Depending on the device and your knowledge, you may be able to take apart an existing speaker or audio device and remove the shielding yourself. To record the audio, you can either use some kind of audio output into another recording device if the device you are using has an audio out. If it is or is connected to a speaker, you can also just use a separate device and microphone to record it. Most modern audio equipment has shielding to protect it from radio interference though as the interference caused to the audio by cell frequencies is of course well known by now and filtered out as to make it so it doesn't bleed into your music! This means that your audio device of choice either has to be older as shielding wasn't needed as much before cellphones became widespread, or it just has to be cheaply designed as to not include the shielding. In the case of headphones and speakers, I'd recommend to use kinds that have a separate power source as the device will need to be powered in order to capture the frequency. Devices that use a 3.5mm jack for power may not work. I hope this info helps. Good luck!

I recently managed to record 5G interference from my phone while i was waiting for this video and I love the sound for some reason. I am now obsessed with trying to reproduce the sounds from these videos for some reason and I love it! Judging by the sounds I think my phone primarily operates on the 3500MHz version of 5G, but my phone tells me next to nothing about its connection so im not sure :/
If you want to see cellular connection stats, afaik, you'll need a modern Samsung Android phone or a modern Apple iPhone and access to their respective field test menus, or a Pixel Phone with a 3rd party cellular network monitor app. Otherwise, you'll have to root a phone if it's from a different brand.
I have an older cheap-ish CRT television on my desk that I use as a computer monitor and the speakers make these exact same buzzing/crackling noises and I never knew it was inference until now, that explains a LOT, thank you for quelling my curiosity 😭
I am unfortunately not able to with my current phone actually, it is not rooted and there are no built in band selector options. This is the reason this video took so long actually, I needed to get some equipment for portable recording so I could go to different areas where certain frequencies are stronger and capture them.
this makes me wonder how loud it would be if you could hear the interference of every device connected to a tower, now imagine them all doing speedtests
I find it interesting how different carriers don't sound alike, even when using the same frequency. I recorded various networks here in the US, and they sound different from your recordings. i tested NSA on bands n2 and n77, and n2 on Verizon sounds very different from your 1900mhz 5G. n77 (3700mhz) sounds about the same as your n78 though. Your AWS 5G actually sounds like verizon's 1900mhz 5G. I also tested all 3 major US carriers for LTE, and T-mobile sounds different from verizon and AT&T. I also managed to record NR SA via a t-mobile network pass. I tested 600mhz, 1900mhz, and 2500mhz. NSA and SA sound mostly the same for mid-band, but when you are idle, i notice the LTE sound more than the NR sound (for t-mobile). for verizon, NSA always sounds like NR, and LTE isnt noticeable in the interference. If you would like to hear some of the US networks i uploaded them on my channel. I am currently working on a video of T-mobile n25 NR SA (1900mhz).
It is very interesting. I checked out some of your videos and I'd definitely be interested to hear more. I'm in Canada here and these were all from Rogers, I know that would still count as North America so there is a lot of similarities to US networks but there are some differences such as the fact Canada only has up to C-Band 3500MHz at the moment due to the fact Canada hasn't officially allocated mmWave spectrum yet. I also mentioned I'm not sure if my Canadian version of the Google Pixel 7 has SA support, I know the US version does, but not sure about Canada or global. The Rogers network here does apparently have SA infrastructure though. The AWS one is interesting as well, that one I actually recorded at a subway station which they just installed service in last year, I'm thinking the reason for that is because in most places a radio spectrum license isn't required to use the AWS band, so Rogers probably chose to use 5G AWS so they could build the new infrastructure quicker and more easily. As for the other Canadian carriers, I haven't recorded any of the sounds from them yet. I know Bell and Telus now have 5G small cells in my area, I've seen them on the poles in my neighborhood so that would be an interesting test. Freedom Mobile also started offering 5G last year, but they're not on 3500MHz yet and are using the LTE bands as of right now, so that might be interesting to test too. (Bell, Telus, and Freedom Mobile are also only NSA at the moment to my knowledge) Also, if you didn't see the first part of this series, looking through your videos and some things I've heard in the past as well, Rogers LTE sounds very similar to Verizon's as well.
Also, a little update, here is a page on Wikipedia that shows the radio frequencies Rogers Wireless uses: en.wikipedia.org/wiki/Rogers_Wireless#Radio_frequency_summary
@@raiacad0564 To my knowledge, most phones sold in north america share the same band capability. Your bands are all similar to ours with the exception of the US using a more broad C-Band spectrum. Almost all US phones also support n78 even though there are no carriers who use it here. I'm fairly sure the pixel 7 supports SA in Canada. It has been a thing for some time now, and most devices support it. Phones typically support bands for international networks for roaming capabilities. Samsung has a utility that lets you select bands, and it shows many LTE bands we have never used (like B3, B1, and B7). I have watched your other videos on this, but the comments i left are under a different channel. The LTE you are testing sounds like TDD LTE, which we also have, however it is used for capacity. Verizon uses band 48 for this, and sprint used to use band 41 before the T-Mobile merger. The network is now n41 and has insane bandwidth (190mhz in my market). I tested AT&T in my area as well, but i do not have footage of the speedtest. It sounds almost exactly like Verizon. AT&T also uses LTE-A, which sounds the same except the lower pitch is missing. It is likely using B30 (2300mhz).
@@raiacad0564 Interesting how Rogers has n78 and n41. T-mobile has n41 here in the US, and AT&T/Verizon have n77. Ironically n41 is usually faster because they have 190mhz here, and it has a slightly longer range than most other networks (including their own LTE network). AT&T has a strange setup though. Verizon owns 200mhz of n77, but AT&T owns 2 different subsets of n77 that add up to 120mhz. They own 80mhz of C-Band, and an additional 40mhz of n77 known as DoD (department of defense) spectrum. They require separate antennas due to the frequency difference. DoD is at 3450mhz, and their 80mhz of C-Band is at the normal 3700mhz. Verizon has a more normal setup with 140-200mhz of C-Band depending on the market. They also own spectrum at 3500mhz known as CBRS. they have plans to deploy this as n48, but for the time being they have it set up as B48 LTE which is about as fast as high capacity 5G. Most sites in heavily congested areas with a lot of traffic have C-band and CBRS. I get over 400mbps on B48, which is pretty insane for a 4G standard. They use 80mhz of B48 usually, and sometimes they aggregate B66 as well. What's interesting is they do not use B48 as the anchor band. B48 is used as a SDL (supplemental downlink) band here, only being used for improved downloads. I cannot test out CBRS from my home, so the interference remains a mystery. It is only deployed where it is needed.
I'm a bit confused what you mean, do you mean cellular or something specialized? Cause Wi-Fi's bands are 2.4GHz, 5GHz, and 6GHz as far as I know, meaning there is no sub-GHz. That is unless you are talking about some more obscure 802.11 standard I'm not aware of or might not be able to get equipment for.
That’s technically what it is First you notice that all cords for computers have a cylinder on them That’s a magnetic core to reduce interference as a antenna is just a wire Old speakers don’t have those as there we’re not needed then Now with how much more radio devices are around such as WiFi and cell they have been added The video maker is useing one of these old speakers The speaker wire is picking up the signal witch is then going through the speakers internals out the headphone jack and into a recording computer
iirc it’s the synchronization signal, used to keep the connected devices on time with each other I’m not exactly sure why they have to be synched, but it’s an important optimization!
Easiest way is to find an old radio or speaker with not much filtering in the amplifier, and aim the antenna of the phone at it. I have an old GE under cabinet radio and that thing can detect a cell phone from like 10 feet away if aimed towards it. Still works great and it's a very clear sounding AM/FM radio and cassette player despite being probably 30+ years old, but it certainly is sensitive to interference. On a side note, I'm never getting rid of it, old electronics just live and live and live.
Yes a lot of 4G bands are shared with 5G. One of the reasons that 2-4g is being replaced with 5g is that it's more reliable since it has so many bands. It's faster and more efficient and has the possibility to travel a farther distance. Sadly though cell providers are using this as an opportunity to kill 2-4g support which is stupid especially in rural areas where 2g might be the only option. 5g essentially takes up all the space that 2-4g used, even though they could and should share the bands, they don't for whatever reason.
LTE and 4G is basically the same thing, but the reason is why it called LTE is that this new radio standard hasn't met some requirements to be an actual 4G standard
