It's line of sight so say you mount it 6 ft in the air the horizon is 5km away. You could get a lot of range if both modules were on very high points with nothing between them to block the signal but in a normal setting the range would be very, very limited.

It's interesting tech but this video is a little misleading.
@@yottakm3764 yes that's exactly how it works. That's why when a radio goes wrong magic smoke comes out 😆. If you want to learn more about radio communication I make videos about it.
Keep seeing comments about the limited range for LoRa. Yeah it is limited. So what? For its design and function, it works. Use it for weather monitoring for now and simple texting when other mediums are not available. Adapt, overcome and quit complaining or go use another radio that is a better fit for your plans.
Everybody’s talking about the range, but no one is talking about that razor-sharp cutout on the PCB that could tear you clean open if your handled it wrong
Simple. Create and install mesh repeaters. On towers. Would be equally great if cell/ data communications wasn't a greedy monopoly that overcharges, limits max data, and also throttles speed. Knows what increase a 28.k modem to 31.6k is, IRL.
@@jensv874 Right now it's very useful for sensor data. It's very useful for low power devices with sensors to measure things like temperature, humidity, pH levels, water levels, pollution, brightness, loudness etc. It's being used a lot in agriculture, power grids, water management and city management.
Also great for off grid devices. In many applications a single small solar panel with a buffer battery is more than enough for 24/7, all year long operation.
@@sporqist Ooh. Just some classic IoT. The helium network is doing this for almost 5 years now. I thought you were talking about something else as use case as you said it is still at its infancy.
10 km in reality won't be possible, but if you want to communicate within a building across multiple floors, it's possible based on the power rating of these modules. I was able to send and receive packets across 4 floors and 30 rooms in between with 2 diagonally opposite rooms with two 1W LORA modules at 434MHz, which is much better compared to a Wi-Fi module like ESP32 but the only drawback is encrypting the signals being sent.
I would compare it rather with BLE class 1 devices which are also very power efficient. Wifi is hugely inefficient for IoT kind of things like sensors having limited batteries only.
yeah clearly, even in the best case scenario, a 160Mhz transciever at 4 watts and a decent antenna would be required. and the board would be full of coils and stuff, not a bluetooth like package.
True i was able to tx and rx upto 7km with 100mW rf power sx1278 at lower bandwidth and higher spreading factor with homebrew dipole antenna on receiver and directional yagi antenna on transmission side ! It was not line of sight though
Rooftop droppable repeaters? Delivered by drone. In fact, activated & droped if range exceeds thresholds. Repeaters, definately. Will they run off a solar cell?
There is more to it than just radio. LoRa stands for long range and includes communication protocols to create low power wide area networks for the Internet of things. Think of sensors that monitor temperature or whatever. They are engineered to run on a single battery for years
Also don't forget that you need to license RF spectrums to commercialize a product. If you're using the public spectrums, which I bet these modules would be using, it would be so crowded that it would most definitely interfere with other devices causing the range to substantially reduce from what is claimed on a data sheet
I’ve done some tests using the SX1268 and SX1278 modules, I can get about 1-3 km using 433Mhz in a semi-urban environment with radios at ‘pocket’ level. Not bad I would say.
Nonway it is gonna be 10-14km even in a straight line without any obstacles due the antenna freq and size these antenna's are used mainly in sim800l modules etc and not for such a long distance but only for short distances like a 1-3km you cannot expect more than that
Imagine the audacity you have to have to decide to regulate, permit, and license part of the EM. Next we'll need to pay for licenses and inspections for proper bandwidth and intensity of headlights.
@@ObservationofLimitsyou do understand that we need some kind of regulating body right? It would be pure chaos if suddenly airplane communications got interfered with by a kids toy that just so happens to be using the same frequency.
@@ObservationofLimits No regulation on certain frequencies, what could possibly go wrong? It's not like the lives of tens of thousands are constantly dependant on the stability of transmissions as they fly through the sky at 500mph or other crazy shit.
Eventually the big mobile networks will become a shadow of what they are now as mesh networks built into phones will allow phones to reroute data through neighbouring phones up to 14 miles away, routing through 10 phones would enable 140 miles data connections and 100 devices would enable calls over 1400 miles. Mesh networking will make mobile networks irrelevant
Mesh and cellular will never be interchangable. They are used for different circumstances. Even if you could somehow scale mesh up to even come close to meeting current cellular needs in terms of the data bandwidth, it would consume far more power by the phone and network hardware to operate. Wifi bleeds phone batteries bad enough at 100 ft. Imagine that power usage scaled up potentially a hundred times. Also, someone would still have to manage the mesh hardware and networks. Mesh would be another big mobile network, just using a different protocol with a much lower battery life.
And if you connect this device to the data connection of you caffe machine, you will be able to make caffe from a distance of 2000 km without internet or mobile connection and with the speed of light. Moreover no need of electricity.
even imagining this glorified wifi thing transmit over 200m would be a success, 2KM is a lot, idk if americans undersand what it is. no it's bigger than three football fields.
