Can you please make your videos without the acronyms and speak to the layman as well? We're here to learn, the most us that is... just my two pennies...with inflation and all maybe it's worth what it is.
"Bowed rate" ??? LoL
It's pronounced "Bored rate" 🤣
You got "U ART" wrong too...
This might be taken down, you say, so why don't you have a backup channel on rumble?
Oh the hate in the comments! (chuckles)
Some command-line tools for dealing with serial "AT" modem-like devices:
minicom - A simple terminal program
cu uucp uuencode uudecode - Old unix-2-unix suite for call-up, copying etc 7-bit-clean
Quick note, even inexpensive uart-to-usb bridge devices usually have a "DTR" or "RTS" pin, that can be connected to the RST (reset) on your LoRa device ... a low pulse, sometimes through a little capacitor. Test this in minicom by sending a "Hangup".
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.
Yes, that is all true. Still pretty sure no one at all will concern themselves with any of that (Except the Ham guys who seem a bit obsessed over those kinds of laws and regulations) Nor is there any chance you'll be tracked down by suits walking around waving directional antennas all over looking for a Lora transmissions or a meshtastic relay on a hilltop some place. Even if they do go out, they do find it, they do take it, well... then for 26.00 I'll put up another one. No one is having their name and address silked onto these lora modules as far as I've heard.
@@williamna5800 Ironically, it is not the government who would cause you problems, but those obsessive ham radio guys who feel it is their duty to rat out anyone that hasn't jumped through all the same hoops as them. The gov't learned long ago that they don't need to pay people to monitor this stuff, because neurotic losers will do it for free, purely out of conformity and spite. These guys literally have lingo to describe the practice of tracking down 'unlicensed' communications.
@@williamna5800 GFY! We'll pin your coax just like in the old CB days.
@@williamna5800 The thing is that Amatuer-Class licensees have ZERO issues self-policing unauthorized activity in their licensed spaces, ESPECIALLY when it comes to flooding and other forms of RF contamination. There are Official Observers (OOs) (and as of 2020, new Volunteer Monitors) who are HAMs that have been trained & authorized to file official reports of incidents. If it's bad enough, triangulating a signal is not hard, and these "Fox Hunts" are often done for fun at HAM Festivals, like a radio-based game of tag. Finding a rogue transmitter is just a sport to HAMs, so if someone is going to be a pest and hurt the community by DoS'ing the local RF bands, HAMs CAN and often WILL track them down. And they'll do it quickly because they think it's fun and a community service at the same time!
"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."
doesn't this only apply when communicating with a LoRa-wan gateway provider? if not i might have hypothetically broken the law... hypothetically of course.
A cheap way to ping your lost pet and get a simple gps location returned without some kind of subscription would make a lot of people happy.
also without having to share with everyone else
Great idea... I might design it....
Just a FYI it has already been done several times if you check on YT here. Might save a bit of coding time. Honestly you'd be better off using meshtastic for the mesh relay to far extend how far the Lora has to cover for something like this. These UART/AT command style modules do NOT work with meshtastic, but you can probably use painlessmesh arduino lib or look into using the ClusterDuck protocol which also can mesh/relay thru.
Please do, I will buy@@BrettFloren
I literally have a lora module and a GPS module on my desk right now. I'm just having trouble getting Eclipse to recognize my USB programmer on my dev system or I would have done exactly that last night!
This is not even remotely WiFi
Exactly Lora is not wifi in the sense of that definition!
No, so "You've never seen WiFi like this" is completely true.
It's not clickbait, it's literal.
@@russellzauner Bullshit. It may as well say, "You've never seen a plasma torch like this."
WiFi = Wireless Fidelity
It's has good fidelity without wire, so it's WiFi
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.
Not always, you should have seen how fast Hillary's emails were taken down.
not surprising. if you look at his older content the guy's a crypto bro. Happy he is trying to expand but he really needs to research things more.
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.
Hey, self pronounced expert: is it common to spell out UART, rather than saying U-art?
@@JensGulin No. It's pronounced U-art as you wrote.
lol! thanks! I was thinking exactly this! I've been shuffling electrons since the early 70's and it took me a second to realize he was just mis pronouncing "baud"
unless you're from Canada. Then it would be bood rate.
lol, you could've directly said BAUD is pronounced like BOARD ;) UART is always 'you-art'.
Yea i have not seen a wifi like this couse its lora duh
Dude, the industry giants don't want you to see it!
That's when I quit watching.
@@nathanahubbard1975 lol
@@nathanahubbard1975 yes that is so ridiculous, these youtubers are jsut the new whores, they would do anything for audience, not a bit of integrity or even doing basic homework.
So tired of clickbait.
@@joetoney184 yep i knew that before i clicked on the video by the picture but didnt know it was gonna be so terrible
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.
yes, typical youtuber i would say, A lot of bullshit and a very gullibe audience.ISM It is true that the 1280 can reach about 250kbps, therorical, but the range will be pretty shitty at this point, less than 1km with easy environement. With the 1262 at 868 or 915M it will be more like 25kbps, with 1% duty cycle max.
Well, tbf he did say you wouldn't be sending video or even images this way, but I didn't like the "what _they_ don't want you to know" BS aspect of it.
Every heard of SSTV, this is still a popular thing fifty years later.
I can think of one reason to use this over wifi despite the bandwidth difference. Okay, two. 1.) It's free, after its initial purchase that is. No service charges. 2.) It's decentralized. Hence the no service charges. But that's about the end of my limited knowledge of these. They're still neato. :) I'd like to get my paws on a couple for info purposed and general tinkering. Maybe you can tell me if these are suitable replacements for IR transmission generally found in the likes of radio-controlled gadgets like drones and RC cars or whatnot. I'm fairly green at this Arduino and esp32 stuff and there are soooo many possibilities out there that sometimes it takes a while even to correctly identify a controller module exactly as the IDE would know it to be when I buy a new, unfamiliar board. (It's been a blast, though. :) This rabbit hole is deep and super fun!)
You know the video is BS as soon as the standard: "This video will be taken down soon!" phrase comes out. Never fails.
The boogie man is after you.
so.... a LoRa... thank you for the clickbait title
How many people watching this immediately thought "Hayes modem commands"?
I just commented yesterday (bragged) to the whippersnappers that "when i got online we had to dial the modem manually w AT then launch the PPP cause win95 shipped w broken dialupnetworking (till MSWin95_DUNupdate1_2.exe) came around. I realized when I was nostalgiazing openly all over myself, that this had been my first shell account - cool.
"You’ve Never Seen WiFi Like This" sure because this is not WiFi...
27 kbps WiFi killer

It's an acoustic modem killer.

So just get 9,259 of them and now you got 250Mbps!
@@freedustin Arithmetic saves the day!
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.
So called "crystal radios" were one the first types of radio receivers and pulled power from the broadcast signal itself. They connected to an earth ground and had a wire antenna, and a very small number of parts. The ones I've seen used a earphone and didn't have a volume control due to the low amount of power available, there was just a frequency adjustment to select the AM station. They did not work with FM.
Just like today... You are the Man!
Note that the word “baud” is pronounced the same way as “odd”, just adding a “b” at the start.
Kids these days. ;)
How helpful is it?
Wrong. Google it
When you use text-to-speech like this you really have to listen to the result and respell words that come out funky if spelled correctly. I'm guessing the creator used google translate to make the english version then fed the result into his text to speech program.
Why am I not creating videos in other languages like this? It wouldn't make me rich but it might earn lunch money.😆
No it isn't. It's.pronounced like fraud.
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".
Well he's (?) ghey, all he (?) needs is a hair bun and a Palestinian flag
I cringed when he mispronounced baud, kind of like nails on a chalkboard.
@@Zeric1 Maybe english is not his native language and he's using google translate. Although his lips appeared to be in sync...
@@lauralhardy5450 Maybe, it bothered a lot of people if you read through the comments. Many people also pointed out hyperbole and just wrong information.
A lot of things in the world are worth being passionate about... this is note one of them. The passive aggressive response is funny though.
Its funny to see his reaction as he just discovered LoRa. We do need more people making products and hosting relay nodes.
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).
Dude, you're killing me. It's pronounced "bod", not "bowed". Sincerely, someone old enough to deal with 300 baud modems.
Lol, me back in the day....
I remember back in the day when modems were measured in bauds some made the joke of saying it that way or a play off tge word body or bods. Its kinda like schedule (sked jule) and schedule (she jule) both are correct..and yes i notice the phonics suck
Baudot is pronounced boh-doh, so technically.., Yes, I remember paper tape unfortunately.
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?
From the thumbnail I took it more to be like a Lear jet and a SAM missile, like this thing kills Wi-Fi signals.

Would love to see more comments like this one
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.
LoRa is spread spectrum
The camera constantly zooming-in is driving me nuts.
Awesome video! One question is this is a Transceiver can this be used to analyze and capture wifi data packets to try and figure out whats going on with a wifi project im working on? I dont know that much im just getting started with more complex tasks with my RPi4!!
Like how could i use this to see the wifi information or packets being sent between devices, when theyre using a 5.8GHZ Wifi protocol from everything i can find about it?
Or what would be a cool project to make to use these in?
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.
Incase you've been living under a nuclear reactor burning hotter tan any heat you'd want to be anywhere near though providing a nice warmth from a perfect distance........Shesh how could something like that exist! Right? So, unless you're living under this nuclear ball.....the earth .is actually flat....therefore unlimited transmission distance!!!

"Wifi killer"??
I don't think so.
If you exceed the 0'1% duty cycle you can be fined a very-very-very expensive fine. (Up to 1 million euros.)
This technology is designed mainly for sensors and IOT devices. And I think it's awesome.
Surely you'd need an array of them esp. if it can't rx/tx simultaneously as uploader suggests.
baud is pronounced like "bod" as in "dad bod". Not Bowd.
I have a perfect idea for safety and lora. It would keep people safe. I think I will try to build one to test out. A simple esp32 or other microcontroller, a single sensor and an emergency call button is all that is needed to hike with, and a simple reciever tied to a cellphone as a base station would be able to make an emergency call if there is an issue. The hardest part is the what if sections of the code. But it would be a cool project
Look up Clusterduck protocol (CDP) if you're interested in that kind of thing.
"This microchip can send datas 12 miles away", no, it is not a "microchip", it ia module, composed of an MCU and a transceiver, none of which is made by the brand you affiliate, as a side note i find it funny enough these modules have the shape of a pigeon, it seems appropriate i would say.
Yup, like a homing pigeon.

I don't a have clue to what you are talking about, but I find it fascinating.

you basically need to be a hacker to know how this will work, I think MAYBE if they start selling from Amazon a completed unit ready to install with a few clicks to work on an individual basis to communicate with "Close Friends and Family" the Limitations is really a bummer, but in the days of BBS before internet this was like the same thing... how to send text msgs over phone lines (of course then as well you couldn't use your land line for communications.
The idea of installing remote weather stations with this tech is brilliant. I recently was introduced to a website called the Weather Underground, which is a network of community run weather stations. Someone in my area has one because there's no government station there, and the weather does differ substantially to the neighbouring stations, so we will be able to use it to monitor when to do certain tasks, like watering the garden.
But there are similarly exposed peaks to your Mt. Washington not far from there either. Mt. Bogong ... the tallest mountain in the state can have radically different weather to the trailheads for climbing it. A weather station transmitting using LORA would only need to have line of site with a server that's connected to the internet to handle this.
Genuinely a brilliant idea.
Yeah! Nothing like monitoring geo and topographical climate change in real time, like watching paint grow and grass dry
@@rawcado I'm not sure what your comment has to do with mine.
weather underground like 2 decades ago is how I learnt the short form of "Weather" for elitist weather nerds is "Wx", aka us cool ppl :). Sure was a great resource esp so long ago and prolly today for areas without overlapping gov/corp meteorological info like we get in cities..
Very cool video! Thank you for making it. I have been interested lately in LoRa stuff and your very basic introduction was a breath of fresh air compared to a lot of what I have seen lately.
I'm an old guy: I've been doing computing since early 1970s. That's back when we had to carve our 1s and 0s outta stone.
UART is pronounced "you-art".
BAUD is pronounced "bawd".
I was exactly like you in my youthful days. I spent my hours reading and learning and working on ideas with boundless enthusiasm. Talk to some folks and you'll learn things like these pronunciations and it's also a great way to share what you know. CZcams is, of course, also great for that.
2:18 "UART" is conventionally pronounced "you art."
5:01 "Baud" is conventionally pronounced "bawd" (rhymes with "awe").
Just a heads up: "baud" does not rhyme with "cloud".
if he was from NYC woulod he say "fugataba-w-udit" :)
For your distance testing, would it be beneficial to set up a ping and return, rather than only counting, so latency and dropped message ratio can be visualized?
Also, I missed how two or more nodes which have the same address and frequency would be differentiated.
I could see the usefulness in this. Even though the baud rate is pretty low, you could still use it for flying UAV’s (remote control aircraft) long distance and still have plenty of room for long distance point to point missions. As long as the aerial vehicle is within line of sight (as directed by the FAA) and it’s not flying in controlled airspace (pilot will need to use a NOTAM for flight planning). I’m not even sure if I said that right. If there are any pilots out there who are willing to correct me, then please feel free to do so. I’m wanting to study for the part 107 exam so I can fly drones commercially and get paid for doing so. If anyone has any great tips, again, let me know.
This is the wave sir!!! Show even more this is better tech than an personal assistant!!
Using the attention (AT) commands to run communication brought me back to 80s/90s terminals!
Same here!
Using a RF Pineapple and DragonOS ...these are very easy to compromise by simply scanning bands or skyjacking frequencies...these need a more secure way to transmit data especially if one is sendinf locations and times. Awesome video and really amazing little device however, thanks.
Cool man, I'm glad I found you! nice work friend.
And it has the fun appeal of QRP., solar powered, parasitic RF ie crystal radio powered etc. (fond memories of LM3909 etc)
Great video made me understand more about how LoRa can transmit such
far distance!!
that wasn't explained. but it does so by blending with background but still being distinguishable from it's preceding preamble sequence. probably the longer this is the more likely msg is caught but less room for the msg.
I'm now in trouble with industry giants, thanks man
You too, no worries I'll have my people call those giants and sort ya, hopefully he's got something uploaded on these giants or I fear I've overcommitted here... Okay chatGPT suggested basic giant speak, like "no FEE, also no wiFI, user not FOE, FUM". fum to terminate like NL,CR chars terminate Lora AT commands. :P
Great content man!
ok bro but what products or routers can this chip be put into so that we can use this as a high scale off the shelf product?
Lol you gotta be kidding, by the time I did all that, I could have sent carrier pigeons to send and retrieve data.
Funny, I was immediately thinking about how I could use this to bridge low-bandwidth data from Bartlett, NH into Harts Location, NH since there is no service when I'm there.
Great video ! I saw a few Meshtastic teasers in there. Perhaps it is worth mentioning it ?
I am a little suspicious about the helix antenna, if it is a quarter wavelength antenna then it requires a groundplane to work properly, the groundplane creates an image of the field from the antenna. assuming that the groundplane is infinitely large, in reality the groundplane only has to be larger than the wavelength to do a decent job. I do think this antenna is optimized for size not antenna gain. Thus large improvements can be done. remember that the E / B field decays with the distance 1/r^2
My guess is its a 'hat' thing anchoring it to the ether, uses ground waves.
@joefish6091 the design of the PCB groundplane is important, the groundplane also radiates.
I also really like cursor. You might also like Warp then, its an AI powered Terminal wrapper, looks very nice and also helps with programming and navigating.
What is a "bowd" rate ?
Haha Was thinking that I'd been the one who has been saying baud(bɔːd) wrong! Weird hearing the term without being preceded by digits! (1200, 2400, 9600)
To be fair, Emile Baudot, after whom the term is named, would be pronounced roughly bow-doh in French, so consistent with his pronunciation of "baud". But yeah, it's almost universally pronounced more like how a Brit would pronounce "board".
@@PeteC62 weird, I've always heard it as "BOD" like body.
It's pronounced "Bored" in every single English speaking country.... SIGH
He got "U ART" wrong too...
It’s a cartoon Deputy Dowd.
the way its pronounced in industry : UART = YOU ART
"traditional terminal like bash" - haha, was using AT commands via a "terminal" before linux was born in '91
Love this video... having flash backs to the 80's, with acoustic couplers and basic programming - just like your doing now!
this is amazing!
Well ahctually.... Bash was released in 1989. Bash is older than Linux too.
@@DanielRisacher Yeah, UNIX has been around for a very long time.
@@DanielRisacher AT command set came out in the early 80's, originally designed by Hayes Microcomputer Products for their acoustic modems. It eventually became the de-facto standard of all acoustic modems.
similar to WHISPER but more compact antenna wise, i have neighbor who has whisper running on 120mw powered by RX and TX/RX range of 10.000M+. it goes over my head a bit but seeing the mesh network and small mobile devices with it it awesome, and its old technology/ software too
I would love to see this on a flipper module.
The Flipper Zero is the perfect platform in my opinion. Feels like a pager kinda
if everyone did this, we could have our own internet. Depending on data rates. @115200 w/ 10x compression you'd have 1 megabit data rate.
0:53 “This video might not be up for long because […]” Was that supposed to be a joke or does he really want viewers to believe that?
In it's heyday, traditional Internet phone modems were 56k (56,000 baud rate). This is roughly twice as fast and can be faster utilizing compression.Only the protocols and translation overhead, and possible security protocols must be accounted for. Analogous to early DSL, ISDN. So a wireless phone modem technology. An enterprising group can build a decent communication system over this that can include audio and video with compression. I like it.
would nee4d an array of em and encryption due to 1% duty cycle regulation.
i think you missed that when he set the 115200 baud rate, that was only the bit rate for the USB to UART bridge. at 8:50 to 8:54 he said LoRa is meant for about a hundred bytes every 10 to 15 minutes, which is a much lower data rate. and wireless data transmission rate depends on other factors, like the LoRa module settings, distance between nodes, interference. but generally the point of LoRa is in the name, Long Range. and to get the long range it means a lower data rate
Nice video, thanks :)
Oh my, such good stuff!
I am interested in this tech. I work with groups that do medical mission trips to other countries. I am technically oriented not medical. I am thinking about communications between the workers that setup separate departments spread over a school campus. They could use small GMSR handhelds but in some poor countries the police may be using those frequencies. Do not want to interfere with them. Sometimes it is like "go get Dr. Whoever to come look at this". "We need more disinfectant at station 4". Things like that. Could this work for that kind of application?
Cool product. Need to find a way to send txt messages that will get forward over cell for times you are out of cell range.
yk i thought i was starting to get somewhere with this mbedded stuff but then you drop this bomb an ion even know what im tryna get into now😂
Good stuff. But I’ve been dealing with bbs, modems and serial ports for 40+ years. The word BAUD is pronounced to sound like “bod” with a long o as in the o in the word body, the a and u are pronounced together to form that long o sound as in the word body.
You could also use direction pings just like aircraft used to use to range find. Put a dual signal on top of the mountain so if you are in a blizzard. you can track if you are on the right path and direction to get to safety. I
Very good explanation
I can’t get good Wi-Fi in my house from a giant router and this tiny thing can send a message 12 miles.
nice proof of concept, but I'll wait for the finished product lol.
Garmin has used technology similar to this before when they started using Sarantel's GeoHelix antennas.
Just discovered this today.. I am gonna try it before my country bans this!
CARTELS WILL BE VERY INTERESTED IN THIS
already using it for years. hahahahahah. together with encrypted satalite phones. Money is no issue there.
Awesome video. You need to save this video elsewhere as well and provide links .............just in case. Do you have a website?
Great video!!😀
Gool old spread spectrum....reminds me of the beginning of packet radio way back when....
And AT commands were used on modems back in the dialup days.....cool.
The amazing value of this....jeeeez... !!!
It's every video , click baits with the title then it's Long-range radio frequency technology that we are all familiar with. We are tech savvy people we know! You didn't just discover it like a secret .
It's baud pronounced like bod. The work baud comes from Baudot en.wikipedia.org/wiki/Baudot_code. It was shortened to just the first syllable in common usage.
Exactly! Thank you! I've always heard it as "BOD" like body. I had a BBS (Bulletin Board System - Pre-Internet) in 1986 at 1200 BAUD. I remember when I started using 2400 BAUD in 1990! Those were the days!
That´s kind of what we played around with back in the day when we started flying FPV with the copters and planes, it´s so much fun to come up with new antennas with different frequencies and that kind of stuff. But everything is prohibited now well you can still steal in New York without repercussion though xD
I'm more interested in this as a pager communication system than an iot management device
Can this device be used to allow cellphones without a sim to communicate with another one with the same device?
Yes the problem of those devices are that there are limits to their allotted data rates per time period. The way they seem to work is basically they set up an in line serial connection, which I guess you could use like modem point to point protocol at probably a horrible rate to literally get the internet. I was thinking of the IDEA, not even really starting, of how I could get internet from my parents where they are like 25 km away. All in all there is not a great way of doing it. I guess if there was a high point I could shoot 2 invisible lasers at a building and look for the other spot on the building for their signal. There is no socially nice way to do it. Today I just have a 110GB cell plan that costs about $110 Canadian a year.
Is the cell phone reception good at your location? If the reception is good then you probably have the best option atm. Cell phone towers have backup power during any electric outages which is a plus. However if your signal is bad, then you might consider a starlink system. The base price is $120 dollars per month unlimited data. The only catch is it does perform worse in stormy weather conditions. Average speed for canadian users are around 100 Mbps down and about 15 Mbps upload.
Ppl; have beamed wifi rf line of sight towers out over 100 miles. you can manually adjust antenna til best signal
Nische. It will be fine and tandy as long as parties understand the rate limit of any data traversing that type of connection.
1:25 transmits vibes of peace and love? Transmits?
Cool stuff!
Awesome, looks like they have even built a bottle opener into the design aha
FCC doesn’t want you to know about the spectrum they designated for LoRa 🤔
Great video! But basic opsec, please do not show the view outside of your window; it could be used maliciously.
What is the power consumption during transmission at full power? It cannot be 0.02A as you show, that is the quiescent idle power consumption.
Biggest problem is when everyone within 12 miles has one in a place like New York city with all the skyscrapers. We could have 1,000,000 people trying to send messages all at once. It would be all lag and messages colliding. Making the device useless. WIFI has limed number of channels. That's another reason why WIFI has limited range. If WIFI had a mile range it would also be unusable.
Do you know that some (maybe most) of glasses on windows has a electrically conductive layer coating from inside ? It normally do quite significant RF attenuation. So for such a range test could be much better to place antenna outside and little away from glass. Or keep window open if possible.
New sub. Found this interesting
AT commands over serial, takes me back to telephone modems.. the more things change the more they stay the same.
Can music be modulated over it, or is it TXT only?
lol, LoRa is ultra low datarate, 2.5KB/s best case, with 1% duty cycle maximum, that is, you can transmit 2.5KB once every 100 seconds, good luck for your audio. LoRa has never been intended for voice, it is a low power long range modulation designed for IoT and IIoT.
How long has Lora been available?
