What a good test! That's a huge distance. Keep sharing with us your projects with Esp32.

Woow outstanding results!!! You did great job man, now I want to explore this board as well. Thank you!

This was very informative. Thank You! Just getting started with LoRa and will bookmark and favourite this vid.

Awesome! I am currently tinkering with an ESP32 + Bluetooth Low Energy and am now very happy that I bought a few more than I actually need. Looks very promising and isn't even really 'done' yet.

The Guy with the swiss accent has gone Back to the Future

wow i thought you have two of these antennas! Impressed how far the signal goes from the esp.

a video full of information. very nice. ive tinkered with 433 Mhz modules, but never came across all these formulas, which wouldve helped me a great deal

great project! greetings from 10km further away :)

Also the conditions are really favourable because transmitter is on the hill. If terrain was flat, both receiver and transmitter would need to be raised high to to ensure the Fresnel zone is not obstructed. By the way it is possible to play with the polarisation of the signal by turning antennas 90 degrees to enhance the signal quality.

Super good high quality work!

SUBSCRIBED, i love these kinds of channel, fun learning

that is damned impressive I would never have thought of this.. Well done fellows.. well done indeed!

I have no business sending any signal over wifi to such distance. But boy, the video is awesome.

This great!. Most interesting part is the ONE WAY telecommunication via Wi-fi!. While watching the video i asked my self "but wifi is bi-directional... how can??" and then you answered the question !!! :)

Very interesting experiment, thanks!

Awesome video! I once tested something similar by sending data from the Teck :'D

Wow, it is looking good for my next project! I think It can replace LoRa modules, thanks for simple explanation!

cool video! loved your experiment!

Great content mate!

Loved your work

5 years later of this video being released I'm still amazed. Future is not old man.

Damn, how is that I find these so interesting. When I was in college, I used to hate these.

Good video, little muddy on logic and rules, both ends are "the transmitting end"

@Jeija Hi, what cable did you use to connect the USB WI-FI Adaptor to the antenna?

Super Erklärungen zur Theorie. Interessantes Experiment.

Pretty impressive!! 👍

omg that's very impressive!

Excellent. liked and subscribed ;-)

Impressive.Nice work

Amazing work 👌👌👌

i remember reading a blogpost about a guy using what he calls wifi-broadcast, where the cummication is unidirectional too but he uses UDP to send video signal

The style used in this video reminds me of 3blue1brown. Nice video.

You just earned my subscription

Very nice video keep doing this🤗

Thats really smart, the one way wifi hack allows you to legally use high gain directional antennas as they are only used to receive.

Great R synopsis. Make a video solving E=mc^2 for time.. really thought provoking.

Excellent video

Very cool, I have the camera built into an ESP32 that is sitting in a drawer doing nothing along with several other ESP32's and 8266's. Perhaps I should put them to work, I have been playing with that idea for some time, this video simply adds to my desire to see it work. I have no need to go 10 K but putting the camera in the back window of my Ford Edge that is hooked to my 35 foot Class A motor home and putting the monitor on the dash of my rig sounds like a wonderful idea. I already have the backup camera system but my rig is over 10 years old now and the innards of the poor old B&W monitor have taken a beating, I need to rewire the power to get it working 100 percent, but now I have it at about 65% with the need for a sharp crack from my fist when it goes out. I have been repairing broken traces on the main board of the little monitor now before every major move, and it is getting to be a pain in the back climbing under the dash to access it all the time.

I'll pay whatever, so i can have internet from Starbucks at my home......

WOW, great video!

great video do you think we can get the same results if we use omni directional antenna ?

Great project man ;-) Schöne Grüße in den Süden ;-)

amazing work)

Yes, wifi protocol needs a package acknowledge in a time slot equivalent to the time the waves travel 100m, otherwise, the protocol assumes the packages was lost. So it is not technically possible to increase the distance of wifi without changing or ignoring this parameter. The use of promiscuous mode is a clever workaround for a unidirectional transmission, though.

Very good job!

What if you could use a directional antenna at ESP32-side? Of course a little bit smaller antenna than receiver, because ESP32 can not feed big antenna, I think. With directional antenna at ESP-32 could you increse the distance?

Fun fact. You can split the transmit and receive signals out to different antennas. Use a higher gain antenna for rx and a lower gain for tx. Battabing butta bang, Bidirectional long range communication.

very nice video , I have question is it single directional this ESP32 only to receive or it can be used to send/receive data either ?

Schönes Experiment! Wäre interessant es mal mit zwei Antennen und zwei Sendern aus unterschiedlichen Richtungen gleichzeitig zu probieren.

good to know, i have fiber 2km away from me, now i can install router fiber in my cousin house and use it!

For a moment I was wondering how your going to establish the link without any RX from the ESP end. Great work.

Great video, thanks for sharing. Do you think there would be a way to do this in reverse but with just audio. So, to describe what I mean more, I would like to transmit audio using a directional antenna to a receiving device (or even better, many esp32 devices that will listen) that is in listen only mode. The idea is for on a large farm in Australia, multiple farm vehicles can be equipped with an ESP32 with a roof omni antenna so they can listen to internet radio streams while out in the fields (where no radio reception is available). I note your receiving antenna is a very large directional antenna, this is why I am wondering if it could be done in reverse so that a truck/car that would be moving around could just have an omni antenna. The directional antenna (or high gain omni) would be at the base, elevated on a roof top or mast.

Great project

Very cool! Do you have a recommendation for a decent ESP32 development board? The smaller the better.

Great video

4:13 where did you get that Ubuntu bag from?

I do have 24 dbi grid panel . Problem is obstacles , can't use it practically for long distance.

man, this maths can burst my brain.

i think its possible to send the signal even further, but you're limited by line of sight, the 2.4Ghz have a limited NLOS ability, basicaly 4/3 beyond the horizon distance. i remember there was a record for wifi transmission done from 2 montains on different islands with over 300km distance.

Nice backpack (4:22)!

Outstanding!

Nice project

This is your daily dose of Recommendation So far Wireless range

that's 。。。。。wonderful！！！！！太得劲了大兄弟

Brilliant!

Just curious about the delay and timing advanced for the transmission.

I gotta say, I didn't notice the video author until I saw that Lua controller channel image in the end of the video, then I remembered who you are Edit : imagine a minetest mod where you connect an esp32 to a Lua controller and possibly a new graphical display

please can you tell me how do you connect your usb wifi adapter with the antena?

In case someone, as me, try to understand how Jeija did this... There is no connection between emitter/receiver, this is achieved by not using conventionnal wifi but just the broadcast mode that is usually only used by the AP to advise any device that it's own network is in range, that mean this data isn't sent specifically to one device but to all of them able to listen (mainly this is network name, kind of password safety...etc). In the esp32-80211-tx sketch, we roughtly take the first part of the beacon frame, then add the false SSID name and then add the end of the beacon frame before to send it. By this way the hidden AP make believe that some other's network/AP are availables. That don't change the beacon frame size, it only make believe another sender exist. The same process can be use to carry data instead of fake SSID's, but the beacon frame isn't extensible so only, 32 bytes can be carried by SSID part, 6 bytes by BSSID (mac address) part and 253 bytes by the beacon Information Element part of the beacon frame. That mean the data to send must be splited in some consecutive beacon frame's with an ID number so that the receiver can reassemble the payload of each frame in order to reconstitute the original data. This process can be use for advertising or some other's legal stuff or... to stole data by a hacker. As you understood it's not an usual way to use the wifi beacon frame, that mean despite the screen of Jeija during the video look like a web page, there is no adress to connect to it because there is in fact no connection between emitter/receiver, it act few like terrestral numeric television (TNT). So it's necessary to have a special program on the receiver side that decode each beacon frame, extract each small payload data and reassemble it. This is probably the impressive job that Jeija did and it's really pity that for some reason (maybe good reason's), he seem to don't want to share specifically his camera example which is really amazing. Understand the code of esp32-80211-tx sketch and even modify it seem possible but the program to decode is definitely out of range regarding my knowledge... My aim was to make a target camera with numeric quality and long range (500 to 1200m). I won't do it ue to decoding program, if someone can and share, I would be very glad.

How can i build a audio transmitter? Sending and receiving

Wait if the communication is one way for long distance if we use two devices 1 for transmit and 1 for receiving we can make two ways communication is that right? (Sorry my English is bad)

OMG I still have one of those giant antennas in the garage... used it for Wifi in the 90s was connected via card in PCI card reader.

nice antena! have you used ESP NOW protocol? is also in 2.4g ghz band.

This is very cool :)

Outstanding

With the 24dB Antenna and 500mW I made contact to the QO100 Satellite. 36000km in 2,4 GHz

I would use this for my home

Alles in einem recht informatives Video... wusste gar nicht daß man da so viel herausholen kann mit einer guten Empfangsantenne. Auf der Senderseite war nur die PCB-Antenne des ESP-moduls nehm ich an? Mich würde auch interessieren was das für ein mega-zoom-rohr sein musste um so nah herangehen zu können. Da gabs doch mal so ein Russen-Rohr (eher ein Teleskop mit M42 canon bajonet wenn ich mich recht entsinne...)

Just unbelievable

100% love this

@Jeija ! Hi I am highly interested in your current set up do you think you could e-mail me the parts required to do what you did, would be very handy for my sounding rocket project

Can you pls list the used components?

Excelent !!!

did u really just use this on-board antenna on the transmitter side? and if so how strong would it be if u would use a good external antenna on the transmitter side, too?

In the UK all the matters is the power of the TX power of the device.

Dear author, would it be possible to publish 1) the final code that actually streams the jpeg data from esp32 with that one-way data stream and 2) some info how your notebook is able to receive it in that "monitor" mode? It would really-really helpful.. The published code (broadcasting some rickrolling SSIDs) is not really helpful to understand how the final project works. Thanks!

Nice video! What kind of program did you use to create the "math formula" part of your video?

Awesome ~~😆

Very good

very nice

Forget the wifi, how did you get that little lens to zoom in like that?

I can only work with arduino ESP32, can the sketch be modified into *.ino?

your video is quite helpful for me for data transmission. Thank u from india

what adapter you use to wifi adapter to antenA cable i need that

So we can stream video from a drone for that distance with just wifi adapter

5:13 Is your mode close to the performance of the ESP-Now LR? Or would that further improve range?

How much power needed to transmit signals to and fro from Mars? Anyone? Does Mars rover has a big receiver or a transmitter?

4:15 ~ Did he say 60 year old antenna? You can get those on Amazon. Great content. Thanks.

So how can we use the built in antenna to transmit and the parabolic to receive? Will it pass thru trees?

Hohenneuffen Castle, da war ich schon einige Male oben, super Aussicht bei gutem Wetter. Kommst du von dort?
