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.

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.

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

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

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

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.

great project! greetings from 10km further away :)

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 !!! :)

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

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

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

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

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

SUBSCRIBED, i love these kinds of channel, fun learning

Super good high quality work!

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

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?

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

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 ?

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

Great content mate!

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)

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

Loved your work

Very interesting experiment, thanks!

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

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

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

omg that's very impressive!

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

Pretty impressive!! 👍

cool video! loved your experiment!

Super Erklärungen zur Theorie. Interessantes Experiment.

How can i build a audio transmitter? Sending and receiving

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.

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

@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

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

Amazing work 👌👌👌

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

Impressive.Nice work

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

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?

Excellent video

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.

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.

what that antenna is being used here, and does it matter as long its 24dbi? also would the use of 30 or even 36dbi antennas possible as i seen some for comercial use

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

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!

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

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

What is the range like with normal antenna like can i use it for a arduino based plane ?

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

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

You just earned my subscription

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.

Excellent. liked and subscribed ;-)

Hello I have one question, with Alfa AWUS036NHA and antenna Alfa aga-2424t can I have 5 km or not

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

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

WOW, great video!

amazing work)

which development enviroment did you use for that project?

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

Great video

Can you pls list the used components?

Outstanding!

Very good job!

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

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

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.

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

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.

Very nice video keep doing this🤗

Great project

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

Brilliant!

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...)

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

Nice project

Can you make a video according weak mobile signal gaining from tower of network. For gain full mobile network

Sir Is there any sensor for 1 kilometer range that can identify the object?

Hello, which antenna are u using?

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

100% love this

man, this maths can burst my brain.

Hi What was the bitrate of the video stream? Was any compression used? cheers Peter

Outstanding

so could you build the same setup in reverse. so the castle has a receiver as well and you have a transmitter as well.Then you duplex them together (I'm not sure on how you would do that). You could then setup a link caperble of transmission and receiving 10k which is also working inside the law?

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.

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

Just unbelievable

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

This is your daily dose of Recommendation So far Wireless range

Вітаю. А де зйомки були? На Україні? . Hello. Where you filmed this video on Ukraine?

where they are? Do you know sigfox?

For example, there are 5 Wi-Fi signals at a distance of 2 km. Can this device receive them and they appear on the screen of my device.I want to use this device to receive signals even if I don't have the password

that's 。。。。。wonderful！！！！！太得劲了大兄弟
