In this video we will be having a closer look at popular phone jammer & booster videos you can find on KZbin. Such circuits either block your phones reception or increase it. So I will build 2 very popular ones, show you how they work and whether you should maybe try them out as well. Let's get started!

Great Scott Sir, there is a another channel name ET DISCOVER has made a signal jammer and signal booster, so sir i kindly request🙏🏻🙏🏻 you to investigate on his video also sir.

[@edwardfletcher7790]

Thank you for exposing this idiocy !! Dave from EEVBlog exposes them too, so you're in good company 👍

[@IshaqIbrahim3]

If there is an electronic component that is common across the videos, then they might be scamming people to empty out excess of junk they have in their stores by making the videos.

[@greatscottlab]

Will do :-) Thanks

[@Speeder84XL]

Yes, that's great - expose them as much as you can. I acutally don't really care, if some people "steal money" from a greedy company like google (who has ruined KZbin, compared to what it once was, anyway), by getting payed for views, that would otherwise not be there (because that's what all is about. There are probably very few people who put up fake content, just for fun. At least not electronics - political content could be a different story though. It's pretty much all about geting an easy way to make money). But, it has gotten to a level where it indirectly becomes a problem foreveryone - especially beginers (who try to build shit that doesn't work and often think they do something wrong them self and because of that wastes a lot of time). Like 50% of KZbin content is fake nowadays.

Some people make thesis about antenna design for these frequencies 😀 and in these videos the dude just coils wire...

[@irreverend_]

​​@@user-kr8tp3ko8zI mean to be fair at those frequencies a little bit of coiled wire (of the correct length of course) would generally suffice. Receiving 1090mhz ADS-B from aeroplanes only needs about a 6.5cm dipole antenna (so about 13cm total). EDIT Which is exactly what I have attached to my window, furthest plane I've picked up so far with full location data being 381km away

You are doing a great service by debunking their disservice. I started with electronics when I was 14 (over 40 years ago) and though it is not my occupation I still play around with it as a hobby. What those channels are doing is beyond dishonest because they not only present BS as facts but also discourage people who want to learn. They will try and make one of those circuits work when it doesn't they won't be able to understand why which may frustrate them to the point of giving up. So, yes, keep fighting the good fight :)

[@lunalangton5776]

[@danielbedrossian5986]

[@lbgstzockt8493]

[@steveg5166]

Definitely expose them! I hate these channels that use false information and even AI, combined with click baity titles to get views. This type of content just serves to clutter up the internet and discourage novices that might try to build the circuits and just blame themselves when it doesn't work.

[@user-vb2ll8nl6g]

While it's obvious that circuits like these can't work at radio frequencies, it should be noted that the capacitive load of a passive scope probe will affect the circuit and most common oscilloscopes can't measure such high frequencies anyway.

[@JakEneAS]

It's a good thing the power output is low. Interference around 125MHz is gonna piss off two regulatory authorities simultaneously. Aviation and communications!

[@shrirajpoojary1871]

I took engineering in the field of electrical and electronics because of Greatscott, electroboom, plasma channel , now i am graduated , time flies fast!!!

[@esuomi]

Past 3G all 3GPP standards have used multi-band radios, so a single band jammer wouldn't work anyway. This combined with the split signal on each band having less power than the cosmic RF background radiation gets into some very interesting physics.

Even 2G at least in Germany uses the 900 and 1800 MHz bands. Though in a rural area, a single-band jammer could work since often times, there only is 800 and/or 900 MHz LTE available there. Most commercial jammers jam all sorts of bands.

[@esuomi]

It's unfortunately a (lot) more complicated than that. For example in Germany for the O2 operator on the 900MHz band has frequencies 880 to 890MHz (downlink) and 925 to 935MHz (uplink) reserved for their use, and both are divided up to 8 simultaneous connections, practically meaning 8 simultaneous full duplexes, probably frequency based so 1,25MHz send/receive for a single device. "Wait, only 8? But there's like 15 000 people in one area!" Yeah, now we're already jumping into Time Division Duplex, asymmetricity and literal quantum mechanics...and we're only in 2G! Anyway, multi-band radios mean they can use multiple channels within one band allocation simultaneously, so that still sticks, it's just a lot lot lot lot more complex than one could imagine right off the bat, and the silly thing is - even if you knew almost nothing or you knew way too much about all this, the end result/solution would still be teh same one, just jam everything :)

@@esuomi 1.25 MHz is CDMA, O2 uses GSM however, which has 200kHz channels (they have 6.4 MHz LTE by having a 10 MHz channel with some LTE RBs being blanked + 3.2 MHz GSM by the way). TDD also isn't used on GSM, but TDMA. Anyways, that's not the point I'm trying to make. The point is, that for short distances it's relatively easy to especially mess up LTE (GSM and NR are much more resilient) by straight up flooding the spectrum with noise. I tried for myself and even a Raspberry Pi with RPiTX and 1/2 length wire antenna apparently was enough to kill the signal for like 10ft. The harmonics caused even killed LTE band 3. On GSM, the MCS got completely messed up. This would be enough for anyone with malicious intentions in mind.

[@esuomi]

Easiest way to disrupt 2.4GHz randomly is to break the Faraday cage of the office microwave oven :)

[@ANANTHASANKAR_UA]

Absolutely right!! We can’t block or boost mobile RF signal by simply these things. The mobile RF system use complex modulation technique such as OFDMA and transmission technique such as MIMO will make them more immune to external interferences. The frequency hopping spread spectrum technique will spread the signal over a wide frequency range, making it more resistant to interference and noise. Modern mobile communication systems employ sophisticated error detection and correction algorithms, such as Forward Error Correction (FEC) and Automatic Repeat request (ARQ). These techniques detect errors in the received data and correct them automatically. It also adapt to changing conditions by adjusting parameters like transmission power, modulation schemes, frequency band and data rates based on environmental conditions. From these observations it is very clear that mobile jamming / boosting is not a simple task. It requires more specialized RF IC and well-designed antenna systems along with complex signal processing algorithms.

FHSS isn't used on LTE/5G and if there only is 900 MHz GSM/LTE available, a simple single band jammer would technically be enough. However, often times you have all sorts of bands available.

[@wireless80211x]

Industry standard for boosting are Cel-Fi GO units.

[@npiper]

RF jamming is EXTREMELY simple, so simple in fact it is possible to do it accidentally, all you have to do is (metaphorically) scream louder than the nearest tower on all the frequencies you want to block. What isn't simple is SELECTIVELY jamming ONLY mobile phone signals and doing it in a way that doesn't end up with you destroying your device while a representative of the FCC (or your local equivalent) observes you.

Whenever possible I do report them after reviewing their contents... Back in my days i was taught by good old school techs, engineers and also my father who was an electrical engineer with extensive knowledge in industrial and digital electronics...
