LoRa is regulated by FCC as well (It’s just license free similar to the ISM band but you do have some limitations, which when exceeded means that you’re disobeying the law. You don’t need a license to use a cordless phone as well). By the way this regulation limits the number of messages that are allowed to be transmitted every hour by limiting the transmission duty cycle to between 0.1% and 1.0% per day depending on the channel. Another note, it’s quite easy to triangulate such a device to find the transmitter so beware when you disobey the law. Also you forgot to mention that the fastest transmissions speed for LoRa is 22Kbps (kilobit, not kilobyte) which will only work for short range communication (not much of a WiFi replacement lol). In order to increase the range to the numbers you’ve talked about you have to reduce the speed to be 0.3kbps or slower. At maximum speed at 1% duty cycle you’re limited by law and not allowed to transmit more than 2.376 megabytes per day. There are less limitations on LoRa for HAMs in case the transmission is in one of the HAM bands (for example some LoRa chips use the 433Mhz band). This case requires a license and has some other limitations. For example encryption is not allowed as well as you’re required to transmit your call sign every time you start a transmission and every 10 minutes of transmission.

This is not even remotely WiFi

Yea i have not seen a wifi like this couse its lora duh

Heh, the "might not be up for long because industry giants prefer you not see this", that is usually the sign of a scam video or article.

Back in 1960 I at 5 to 7 yrs old,was given a small device( radio) that you clamped onto a lampshade steel bracket( back when lampshades used a brass or steel shade bracket),or some peice of steel.it was able to pickup radio stations with no battery and worked on static electricity . It had a volune control and staion changer,was the size of half a cigarette.

good intro... but for now what you said is just straight bullshit. LoRa is regulated to use different frequency in different part of the world, like 915MHz, 867MHz, 433MHz, and then there is the data rate, right now, LoRa theoretically top out at around 250kbps with 2.4GHz LoRa specification. You can't even watch your own video with that kind of bandwidth. You are misleading those people who don't have a strong background. In no world will LoRa replace WLAN. Then again, if your are already using 2.4GHz band, why not use Wifi then? It has way more bandwidth and crucially generally supported by most devices nowadays. If you would like to use on DIY project, why don't use a ESP32 then? It just as easy to use and it's way cheaper then LoRa modules. You are a very smart guy and I did learn a lot from watching your other videos, but probably should have done more digging before making this video.

I spent several years in the Industrial controls industry and the company I worked for made hardware and software peripheral devices for Programmable Logic Controllers of different vendors. Our serially connected devices used the computer's serial port (9-pin or 25-pin) and, although versatile it was bound by the slowness of the UART (pronounced "You-art"). (UART stands for Universal Asynchronous Receiver Transmitter). The data rate of the UART is known as the Baud Rate (pronounced "bod rate"). Nobody in the industry (and I spoke with a LOT of engineers and systems integrators) ever called it the "boud rate". It's baud, rhymes with "Maud".

Just an FYI, 'BAUD' rate would rhyme with Applaud, Maraud, Fraud, etc. It is not pronounced like it rhymes with Loud, Cloud, or Shroud. GREAT video though, well done.

27 kbps WiFi killer

FYI, UART is generally considered an acronym, not an initialism. That means you pronounce it "yoo-ahrt" (like a word), not "yoo-ay-ahr-tee" (individual letters).

LoRa is not entirely unregulated. You'll be in trouble if a single device is on over 1% duty cycle.

I'm still using ancient XBee's for my long range open source communications. Good enough for a serial terminal via wireless FTDI interface, with 25km range easily achieved. Only downside is low bandwidth, as well as lack of encryption. If you can catch the signal, you can decode or jam it (by tuning to the same frequency and transmitting white noise). It's quite fragile and susceptible to interference. I also liked using 1st gen BlueSmirf boards, graded for industrial use. Bluetooth with a 100m radius. Can you imagine! That's what card skimmer thieves used to put into their gadgets, so they could drive by and retrieve data without even getting out of the car.

These are amazing little modules, easy to use with simple Serial control and insane range. Using decent tuned DIY antennas they easily make 11 miles LOS so far. As a side note: no reason for the "wifi killer?" thumbnail thing, kinda clickbaity for something that is in no way at all related to wifi. That's like showing a picture of a Ford Focus with "Learjet killer?" You can't really run to the corner store in a Jet and you can't drive a Focus across an ocean, why pretend to compare them?

there is a swiss youtuber, who toys around with lorawan (european bands) and he tested it in alpine settings. connect to a known base station from a mountain, with a good antenna: maximum range 200km. or in other words: the main problem is suddenly the earths curvature. totally scary idea: what would be required for EME (moonbounce). regular moonbounce transmission require more than 100W sending power, way more than what lora specs allow. but since the requirements for a successful connection are lower too, a few watts might be sufficient.

How many people watching this immediately thought "Hayes modem commands"?

Once I heard him pronounce "baud" I started to doubt everything else that followed.

so.... a LoRa... thank you for the clickbait title

Data trooper is a massive thing you have to consider because you can’t just replace Wi-Fi with this and connect 100 clients with no problems
