In this video we will be having a closer look at popular phone jammer & booster videos you can find on KZfaq. 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!

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 KZfaq, 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 KZfaq content is fake nowadays.

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 :)

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.

@ANANTHASANKAR_UA 23 күн бұрын

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.

@npiper 22 күн бұрын

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.

It is almost impossible to prevent people from finding schematics of non working electronic devices. But what one can do is not spread schematics or link to them if one has not tested them or does not know whether it is a working design or not. In a forum about electronics I visit on a regular basis we started including comments IN the image of a schematic stating whether a design is TESTED/WORKING or UNTESTED, so that if the schematic is picked up by some search engine (typically the text normally accompanying the schematic is lost), the status of the schematic is clear to the person finding it. This will hopefully help a beginner who can not see for himself whether a circuit makes sense or not to decide whether he wants to spend time and money on it or not.

Greetings from Argentina! Great work stating the pure facts without nonsensical claims and unnecessary statemens while going right down to the point. After being an senior electronics tech, designer and service tech for 33 years, having started very young as a hobbyist and a diyer, i get sick to my stomach every time i see these fake videos pop up in my feeds. 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... Today we open a video streaming platform and we find this junk!. I try putting myself in the mindset of an electronics hobbyist in his o her first steps into this great trade and hobby and i feel so bad for them and how discouraging their "unknown" failures at building some circuit because of these fake channels with fake impossible-to-work "circuits".
