"It's GSM!/UMTS!": In Canada, we have long used the GSM EDGE standard and WCDMA standard which has been upgraded overtime to support UMTS, HSPA, and HSPA+ meaning yes, my 2G is GSM/EDGE my 3G is UMTS/HSPA+. I am on the CITYFONE carrier which is a subsidiary of Rogers. Look up more about CITYFONE and Rogers wireless if you want exact network details. "How do you record these sounds?": Search through the comments, I've already replied to this question multiple times. "What about 4G?": 4G is the same as LTE. To explain the history behind it, when 4G originally came out, the first few releases did not meet the standard criteria of being a "4G" network, so LTE short for "Long Term Evolution" was made to fill in the gap between 3G and the original goal of 4G. Since then the criteria has been changed to a point where 4G could be considered any network with significant performance and technical improvements over third generation networks (3G). Nowadays the terms LTE and 4G are often interchangeable and "4G" is also typically used when phones are set to a language other than English. "What about 5G?": I do not have 5G yet. Though CITYFONE is a subsidiary of Rogers which has a 5G SA network, CITYFONE has no 5G plans yet probably due to Rogers not allowing them to use the network. I cannot control this and I'm not planning to switch to another carrier, so either I'll have to wait to get 5G, or get one of my friends who has 5G service to collaborate with me, both of which will take time. "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?
It also depends on the phone/firmware. As example, a stock Xiaomi phone shows 4G, while the same phone flashed with, say, LineageOS or a Google Pixel will show LTE.
I’m very familiar with the 2G sound as 2G would often interfere with AM radios so often you would hear that sound in your radio if your phone was near it! :)

@@WTC7 It’s very possible that the older smart meters that were installed between 1998 and 2006 used 2G to connect to the network to transmit their readings to your electricity company in real-time.

LTE just gets angrier the more work you put on it, 3G is just like an retro game of some sort, 2G is for the reason why the old speakers would just do an rythm when you recived a phone call and also the higher and lower pitches mean downloading and uploading
1:25 The reason upload sounds like static is because these systems are usually duplex, using different carrier frequencies for the upload and download channel, meaning the upload channel might be more out of tune for whatever circuit is picking up the radio
Analog radio is a fun topic and an even more fun rabbit hole for those that care. This is a piece of the puzzle for sure but probably not the biggest one. The static sound is because of the bitrate exceeding the frequency response of the human ear, and in this case over video, the microphone and then again youtube's compression, THEN the human ear. Walking back to 56kbps dial-up, you'll get a similar sound although you'll hear both transmit and receive at similar volumes. 56kbps, or in a good analogy, 56kHz in theory, is way beyond the typical 18-21kHz range of human hearing, 20-30kHz range of audio recording equipment, 16-18kHz range of youtube's audio compression, and 11-19kHz range of audio listening equipment. Even before scrambling (a fun google rabbit hole in its own right) we'll only be hearing the brief pops and crackles of when the signal (accidentally, because it's not a good thing) stays high or low for quite a few bits in a row (or at least averages out differently to the rest within our hearing range). This is only the transmit side, too. The speakers probably don't pick up the receive side beyond the (ack)nowledgement "hey i got that data" transmits back. Received data sounds the same if you ever go back and listen to high speed dial-up captures. There IS a relation to whether it responds to certain carrier frequencies better or worse, but the bigger difference here is hearing the radio inches away from the speaker versus probably not hearing the radio miles away that we're talking to, at all. The static sound itself, has more to do with scrambling, and just how absurdly high the data rate actually is. Rant end, hope someone learns something.

I remember when I was in first school, about six years old so 11 years ago and I heard the 2g sound on the teachers computer speakers, the school was in the country side so the phone obviously had to have quite a strong power output to overcome the impedance of the air. Heard it several times into the future but it died out with 3G coming in.
@@BluelightAmeliayou almost certainly do not have 1g service as that’s basically just fm radio and anyone could listen to those phone calls, as well as only ~50 people could access a tower
That 2G sound threw me back to high school in 2005 lol One class We had, the teacher left the TV on all day every day, just usually on a black screen. If it ever made this sound, the whole class would be like "oooooh someone's got a cell phone on!" and the teacher would just give this stern look while someone sheepishly pulled the phone up over the desk and turned it off (or acted like they were entitled to having it on). Such moments
2G is very loud compared to the others. I only ever could hear the 4G noise with an old headphone amp connected directly to the phone. But 2G went into almost everything. In a very small town I noticed the provider deployed 3G when the noise was gone.
Cell radio's been getting more efficient over the years. 2G is very high power (and coincidentally both immensely more harmful than the "5G microwave your brain" meme and now banned if memory serves right for that reason (and its interference with other lower power things). 3G less so, and 4G even less so. The range isn't as good as it used to be, but it's better range for the power used regardless.
Used to run lights/sound for a small theater and the interference from the audience's cell phones was pretty irritating. I assumed they changed the frequency or something cuz it didn't happen as much after a while. Cool video, thank you.
Back when I was in high school (early 2000s), hearing the RF interference (2G/2.5G) from speakers was a dead giveaway when somebody had a cell phone turned on (we weren't allowed to use cell phones, but could carry them if turned off). Especially GSM phones (Cingular/AT&T, T-Mobile) which seemed to be super noisy compared to CDMA.
It's because GSM (and the old IS-136 D-AMPS system) used TDMA, so the transmitter was turned on in pulses. GSM had 8 time slots per channel and IS-136 had 6, so to get the same energy per bit the TX power level had to be 6 or 8 times higher than a CDMA based system like IS-95 - the average power was the same, but since the peaks are larger you get much more breakthrough with TDMA.
@@Coolshows101 I'm sure some kids did put theirs in airplane mode, although back then it was just easier to turn them off/on-- most Motorola and Nokia phones then turned on pretty fast compared to smart phones.

@@Jdjdjdjdhfjbgdgjd Yeah, you're right. The airband is VHF and most cell frequencies are UHF if I remember correctly. Still, I guess the airlines want to be absolutely sure.
Dude god it's so weird to think about what's in each signal. First it's looking for a tower and so it's basically just pinging until it gets a pong. Then it starts out with carrier information from the SIM, information about the phone, then it goes into your internet protocol info (i.e your IP and MAC address), and then finally does a request to the website and then starts downloading or uploading any data related to that web activity. And yet, because each evolution had to cram more bandwidth into a narrower frequency band, they all sound so completely different because they follow such different protocols, even though they often share many elements (GSM is GSM is GSM)
LTE sounds will always remind me of being at the cabin. There's a radio there that I would put on to sleep. And usually, I'd have LTE on and it would interfere. It would get REALLY loud close up.
You don't really need a "powerful" guitar amp. It works just fine with my little Valeton Rushead Max. I think only the pickups play a role here, as they are essentially electromagnets.
I'm planning to record the 5G sounds in the future, but do you know if there's any difference in the sound between low band and mid band 5G? Cause I have 3500MHz in my area now but I'd also be interested in recording 600MHz, 2100MHz and so on and so forth.
@@raiacad0564 I can tell you for sure there is a difference, but i don't know what mid band sounds like. Mid band is a completely different frequency range, so it would have to be different. Low band sounds a lot like 4G LTE. I wish i got mid band, but I don't (or my phone lacks that antenna, thanks samsung). This is what my speakers pick up for 5G (if links aren't disabled): th-cam.com/users/shortsORO5LSxhL5E?feature=share Its incredible how easy it is to hear mobile data.

@@raiacad0564there likely is, 600 MHz is FDD while 3500 MHz is TDD meaning it will sound different when uploading. Though it would be similar on TDD-LTE and FDD-LTE.
If your carrier uses NR-NSA for 5g then it will sound very similar to 4g as it piggybacks off of the existing LTE infrastructure to get 5g deployed quicker
I have a cb radio and cell signal booster in my pickup. I work in forestry and we have firewatch to do every day after work in the summer, usually 1 to 2 hours depending on the time of season and severity of fire weather. When sitting in my pickup, i will hear the lte signals in my cb speaker. Theyre very faint and can only be heard when the pickup is off and all of its own modules have stopped talking after a few minutes. Took a bit to figure out what was making the noise, then i figured out every time i scrolled or went to another web page, the noises came back. Then i remembered the antennas for the cb and cell booster are a couple feet apart on the roof, so it made sense the cb was picking up the the lte signals. I also have a phone with 5g and it sounds identical to my older 4g lte phone. Likely because they share similar tech in the towers to get 5g out
That might be your phone, because I just changed mine to 2G and it worked. Will say though, sometimes you may need to wait for a bit longer because it's taken a bit of time to connect for me before.
@@NIMKAOriginal Didn't see this comment but yes, I figured that out later though and told this person somewhere else. For the record though, I am on a Rogers subsidiary and Rogers is the final carrier to have a 2G network in Canada. Rogers also shut down 1900MHz for 2G and 3G in 2021, so only 850MHz is still available.
I don’t understand why switch off 2G? Should be kept as an ultimate backup incase of an emergency. Old and reliable, 2g signals at lower frequencies travel further and penetrate buildings more. If a storm takes out your local 5G tower you’d wish you had 2G to make an emergency call pinged from a tower that could be much further away than a 4g/5g tower
I once had a 3g dongle near a soundboard I was passing my Computer's audio through to my headphones and I was wondering why I kept hearing strange noises through my headphones. Then I noticed how close the 3g dongle was to it and realised it was interfearence from that
When using my old iPhone 8 and some cheap crappy earbuds I could sometimes hear LTE interference, and it sounded like a bunch of angry pixels moving away
I had a headphone amplifier and was about 300m away on a hill from a millitary radar situated also on another hill. It had a short burst every 6 or was it 10 seconds, it is because they send in pulses just like our semi-duplex phones sends data. I could hide behind a rock and not get hit. And during decend it wasnt many degrees lower than its horizon I could hear it.
I remember Nextel phones making a very strange and unmistakable sound when something near it would be affected by those phone's radios. I could definitely identify that sound out of a "lineup" like these LOL
2g also has sound, often you hear speakers 2g noise a little bit before phone actually starts ringing. I remember the sound being like short with tiny gaps of silence repeated few times i think
3:05 ahh that brings me back to my early teens when i got an AIM message on my sidekick 2 in front of my VAIO computer speakers playing a Linkin park mp3 rip with a misspelled title
Now I wonder if my iPhone is actually connected to 3G when it says LTE because my interference sounds more like it Edit: Wikipedia says my model of iPhone (the 13) supports: GSM, CDMA, 3G, EVDO, HSPA+, 4G LTE, and 5G Well, it might be useful to know that the signal is pretty dogcrap inside my home, so you have to be facing a certain direction and be in one of the patches of "coverage zones" (as I like to call them) to get any service. You also need AT&T to get any service in my area (they're the only ones who decided to build towers out here). The towers do support 5G, I've been near one and indeed it says 5G, just it covers barely any area because of the mountainous terrain
Interesting. Although I doubt it's 3G as that's been shut down in the US. I am not sure which technologies AT&T is using though and what band of LTE they are using. I am in a large city so I typically get 1900MHz + 600MHz or 1900MHz + 700MHz LTE Advanced. You might be on something like 700MHz or 850MHz LTE considering the range.
I totally freaked out once when I left my cell phone near a CRT monitor during a LAN party and it distorted the hell out of the picture just before receiving a call. I don't remember if it was GSM or if it was still D-AMPS (aka TDMA), thas was over 20 years ago. That day I learned CRTs don't like cell phones. 😂
i think this happens because your receiver can pick up the frequency of the connection of the internet. and the lower the G the lower the frequency so thats why 2g is so loud

And yet, because each evolution had to cram more bandwidth into a narrower frequency band, they all sound so completely different because they follow such different protocols, even though they often share many elements (GSM is GSM is GSM)
The 2G sound brings back childhood memories of dance class when our instructor was setting up the music 😌
I used to be terrified of the 2G sound ahaha
I love the sound of mobile phone interference, 2G is just so nostalgic...
0:15 LTE sound
1:30 3G sound
3:01 2G sound (Turn down your volume, its loud)
It’s funny to hear the speed difference , but I surely miss the 2G interference sound. It’s like nostalgic to a lot of us I guess.
Ahh the 2G sound. That auditory snitch that told the teacher that someone was on their phone
3G is infinite horror game potential
LTE: the more work the more screaming 3G: “ calm “🏕️ 2G: PANIC 🗿
LTE sounds will always remind me of being at the cabin. There's a radio there that I would put on to sleep. And usually, I'd have LTE on and it would interfere. It would get REALLY loud close up.
Yup, when 2G stepped in the ring, even thought I knew it's the video, but I still had that mini heart attack when I get a call, lol.
I love how they go crazy when it says Speedtest
Wait, so old dial-up modem sound effects never went way? They just hid them?? 😂😂😂
2g sounds like a swarm of pissed off hornets
You can also do this with a powerful guitar amp and putting you phone next to the guitar pickups
You don't really need a "powerful" guitar amp. It works just fine with my little Valeton Rushead Max. I think only the pickups play a role here, as they are essentially electromagnets.
A fly in your room when you're trying to sleep be like...
ah, old radio sets.... you always knew you get a call before even the phone rang :'D
2G sound brings back memories
I love the old sound of an incoming SMS or call back in the good old days. Nothing like destortion
i've actually done this
dropped my phone by a set of speakers and heard sounds. 5G sounds a lot like 4G.
I'm planning to record the 5G sounds in the future, but do you know if there's any difference in the sound between low band and mid band 5G? Cause I have 3500MHz in my area now but I'd also be interested in recording 600MHz, 2100MHz and so on and so forth.
@@raiacad0564 I can tell you for sure there is a difference, but i don't know what mid band sounds like. Mid band is a completely different frequency range, so it would have to be different. Low band sounds a lot like 4G LTE. I wish i got mid band, but I don't (or my phone lacks that antenna, thanks samsung).
This is what my speakers pick up for 5G (if links aren't disabled):

Its incredible how easy it is to hear mobile data. Just grab some old computer speakers and put your phone next to them. This trick also works with some other radio devices, such as handheld radios.
It is very similar because both 4G and 5G are QPSK to 256QAM although 5G additionally brought back BPSK.
@@raiacad0564there likely is, 600 MHz is FDD while 3500 MHz is TDD meaning it will sound different when uploading. Though it would be similar on TDD-LTE and FDD-LTE.
If your carrier uses NR-NSA for 5g then it will sound very similar to 4g as it piggybacks off of the existing LTE infrastructure to get 5g deployed quicker
As a kid when I heard the 2G interferrence I thought it was aliens trying to connect with my pc
The 3g sounds kinda like those creepy undertale sound clips or like coming from a horror indie game XD
I have a cb radio and cell signal booster in my pickup. I work in forestry and we have firewatch to do every day after work in the summer, usually 1 to 2 hours depending on the time of season and severity of fire weather. When sitting in my pickup, i will hear the lte signals in my cb speaker. Theyre very faint and can only be heard when the pickup is off and all of its own modules have stopped talking after a few minutes. Took a bit to figure out what was making the noise, then i figured out every time i scrolled or went to another web page, the noises came back. Then i remembered the antennas for the cb and cell booster are a couple feet apart on the roof, so it made sense the cb was picking up the the lte signals. I also have a phone with 5g and it sounds identical to my older 4g lte phone. Likely because they share similar tech in the towers to get 5g out
3G sounds a bit like retro noise..
this playlist is a bop
until recently there was 2g in my area and i had wired earphones. whenever i was going online while wearing them, i was hearing that 2g sound
This sounds like the old desktop speakers my grandma used to have
Please make a 10 hour version of this banger
damn, so my speakers aren't broken, it was just LTE interference for these past few years lmao
As a kid i never realised. So this was why my computer speakers made that sound whenever a call came or something else.
Loading small websites by 3G sounds like summer evening rain ♥️
Man, I remember when I was sitting in my dad's truck, then hear the 2G interference from his speakers, then he would answer the call like: "Hello?"😂
This is really interesting! How did you get 2G to work? My phone would never connect properly if I changed the settings.
That might be your phone, because I just changed mine to 2G and it worked. Will say though, sometimes you may need to wait for a bit longer because it's taken a bit of time to connect for me before.
Pretty sure that your carrier doesn't support 2G and lower anymore
@@NIMKAOriginal Didn't see this comment but yes, I figured that out later though and told this person somewhere else. For the record though, I am on a Rogers subsidiary and Rogers is the final carrier to have a 2G network in Canada. Rogers also shut down 1900MHz for 2G and 3G in 2021, so only 850MHz is still available.
@@raiacad0564O2 is very old and Giffgaff runs on o2 so my carrier still supports 2g
I don’t understand why switch off 2G? Should be kept as an ultimate backup incase of an emergency. Old and reliable, 2g signals at lower frequencies travel further and penetrate buildings more. If a storm takes out your local 5G tower you’d wish you had 2G to make an emergency call pinged from a tower that could be much further away than a 4g/5g tower
2G so nostalgic
i like this. if i ever get into making music im gonna use these sounds in songs
I once had a 3g dongle near a soundboard I was passing my Computer's audio through to my headphones and I was wondering why I kept hearing strange noises through my headphones. Then I noticed how close the 3g dongle was to it and realised it was interfearence from that
Weird...I've heard these sounds randomly before through audio equipment. Now I know what it's from.
I turned my volume up to 100 for 2G
When using my old iPhone 8 and some cheap crappy earbuds I could sometimes hear LTE interference, and it sounded like a bunch of angry pixels moving away
I had a headphone amplifier and was about 300m away on a hill from a millitary radar situated also on another hill. It had a short burst every 6 or was it 10 seconds, it is because they send in pulses just like our semi-duplex phones sends data.
I could hide behind a rock and not get hit. And during decend it wasnt many degrees lower than its horizon I could hear it.
i usually hear 2g when i get a phone call since my headphones broke so i gotta use old speakrs
0:57 when you turn on a old mega watchman with no fm radio:
1:47 looks like rain
I love how the sound sounds more spatial and fuller (fequency modulation to QAM instead of PSK) compare 2G to more advance trasmit standard
So THAT is where that noise on the speakers came from!
I could honestly fall asleep to this
3:06 This is legend!
I've never been so fascinated by random signal sounds...
The sound of 2G takes me back to the mid-2000s, pre-iPhone.
I remember when old speakers made the 2G sound, my dad has a digital alarm clock and at night I can hear the same interference sometimes lmao
I remember Nextel phones making a very strange and unmistakable sound when something near it would be affected by those phone's radios. I could definitely identify that sound out of a "lineup" like these LOL
I was wondering what that noise from my headset was sometimes. This explains it.
The best asmr I’ve heard so far.
2g also has sound, often you hear speakers 2g noise a little bit before phone actually starts ringing. I remember the sound being like short with tiny gaps of silence repeated few times i think
3:05 ahh that brings me back to my early teens when i got an AIM message on my sidekick 2 in front of my VAIO computer speakers playing a Linkin park mp3 rip with a misspelled title
Now I wonder if my iPhone is actually connected to 3G when it says LTE because my interference sounds more like it
Edit: Wikipedia says my model of iPhone (the 13) supports: GSM, CDMA, 3G, EVDO, HSPA+, 4G LTE, and 5G
Well, it might be useful to know that the signal is pretty dogcrap inside my home, so you have to be facing a certain direction and be in one of the patches of "coverage zones" (as I like to call them) to get any service. You also need AT&T to get any service in my area (they're the only ones who decided to build towers out here). The towers do support 5G, I've been near one and indeed it says 5G, just it covers barely any area because of the mountainous terrain
Interesting. Although I doubt it's 3G as that's been shut down in the US. I am not sure which technologies AT&T is using though and what band of LTE they are using. I am in a large city so I typically get 1900MHz + 600MHz or 1900MHz + 700MHz LTE Advanced. You might be on something like 700MHz or 850MHz LTE considering the range.
@@raiacad0564 I just checked the coverage map and AT&T uses 4G LTE
3G was oddly soothing
2g is the sound my baby monitor would make on road trips even when it wasn’t turned on
Funnily enough, I can hear these sounds when my phone is near my theremin. I suspected that this was the source.
i heard those LTE sounds when i put my phone in my top loading cassette tape player, pretty cool!! :D
WE GONNA GO TO BOOTH TUNNEL WITH TIS ONE 🗣🗣🗣🗣🔥🔥🔥🔥🗽🗽🗽🗽🗽🗽🗽🗽
I live in Japan but I never heard these noises while using cellphones near a speaker.
Didn't 2G shut down in Japan in 2012?
2:46 omg we heard that for the first time in my dad's car years ago, we thought the stereo was broken
2G is crazy
some people still get confused with 4g and LTE they are the same thing
Calling family in PR, I hear all three
everyone just loves the periodic 2g pings and then there's the pre call tut tut tut tut tut tut tutuuuuuut riiiing
fun what tdma does
It Sounds Like The Radiation Ringtone
i love how all of it just sounds like morse code but 17355367432 times faster
I totally freaked out once when I left my cell phone near a CRT monitor during a LAN party and it distorted the hell out of the picture just before receiving a call. I don't remember if it was GSM or if it was still D-AMPS (aka TDMA), thas was over 20 years ago. That day I learned CRTs don't like cell phones. 😂
the speedtest download is some nightmare fuel level shit
i work in telecom i am unfortunately accumosted to sounds like these
Should have done 2G calls and texts as those are most well known sounds of GSM
i think this happens because your receiver can pick up the frequency of the connection of the internet. and the lower the G the lower the frequency so thats why 2g is so loud
I wonder if AI can translate these sounds in future.
I remember hearing 2G sounds in my childhood. I didn't know they were 2G back then, but damn, those memories!
I can actually hear my phone’s LTE if I put it up to the side of my headset. Always wondered what the noise was and now I know.
Waiting for 4chan to glean your credit card info from the sounds
shoulda had this run through an oscilloscope to SEE what it sounds like too
Is this why I’m depressed I’ll assign it 9% of the reason.

@@Gabriel41932 =D
hmm, with a wide enough band one could probably decouple this like dialup
Huh. On speedtest is noticeable how much more is going on because your mobile provider gives you higher packet priority than usual.
A 56k drop would have really tied to video together.
2:56 maybe a ping test?
