Hi, I've been working in the RF engineering space for over 15 years, some insights. There will be a limit to range due to the transmit power of the devices, this is something that is usually limited by region, hence the reason why you need to pick a region on the inital set up, this is usally called reglatory domain, and controlled by the FCC in the US, OfCom in the UK and ETSI in the EU. A larger antenna does not mean that you will be able to transmit further, however it does mean that the device can 'hear' more, as it has a larger capture surface. The antenna used in the video, both 'stubby' and 'whip' are known as omni-directional antenna, this is because they transmit their power in usually a 360 degree radius from the antenna, range is also liimited with this type of antenna as it is transmitting in all directions, think of the power being divided equally in a 360 degree circle around you, the target node is in one of those directions so would, for example, only be receiving 5% of the transmit power of the originating device. Range could be dramatically increased by using a directional antenna, for example a 20 degree one, as the transmit power would be divided over a much tighter space. This is quite simplified, mulitple other factors such as polarisation and attenuation come in to play as well, and this is a comment, not a white paper :) LoRa is not a 'illegal' technology, it was developed to fulfill a need in both urban and rural remote areas to transmit data, usually from autonamous nodes such as traffic lights, weather stations etc, where the data payload is low, its also used quite heavily in the farming industry to track wildlife, report on the health of crops and machinary. It also uses a lower frequency than traditional WiFi, which means the wave length is longer, and is able penetrate more dense materials, there for increasing its potential range. The one concerning thing highlighted in the video for myself, was the ability to track nodes, it seemed like you were able to determine the location natively on the device of a node without any kind of authentication. Another note to add would be SIGINT (Signal Intelligence), if someone is planning on using these devices in a situation such as a warzone or potential conflict zone (I'm thinking of civilian communications in Israel or Ukraine), as this creates a mesh network, meaning there will always be some level of RX/TX from these devices, by either relaying of messages, or attempting to discover new nodes in the mesh network, these devices would be quite easy to track down for an equipped force, potentially aiding in the capture or attack of the user. The equipment needed by people/govenments/militaries to track these types of signals is fairly ubiqutious now and rather cheap, something to keep in mind. SIGINT operators utilise 'listening posts' or devices (drones, AWACS etc) to 'listen' for RF, trianglate the signal and direct forces to that location (or order strikes), this has been used to great effect by the Ukraine military against the Russian Federation in the early part of the conflict for example.

I appreciate you sharing your knowledge, I’m new to Lora but have been messing with FPV drones for years now on 2.4 and 5.8 after reading I upgrade my DJI transmitter antenna that were basic folding bipolar to a square “patch” antenna I believe it was called and it was a huge ungraded for range and video quality but also very sensitive to facing the right direction. Is there similar “patch” antenas that will give similar results for these Lora devices. Line of sight is very important on our FPV stuff. Forgive my ignorance on the subject if I’m not comparing apples too apples.

​@@DimMakTen31 I imagine there is, although I imagine quite rare given the nature of LoRa - directional antenna's are somewhat counter to what the technology is trying to achieve. Try searching for the LoRa frequencey used in your region and antenna suppliers, you may get lucky. Its important to get the antenna that is for the correct frequency, else this can actually impact range and performance, and may even damage radio equipment through back reflections into the transmitter - as explained in the video. We often discribe 'listening' or 'hearing' signals, but its actually more accurate to say 'seeing' signals, the best way to think about the signals and their radiation/propagation, is to think of a lantern and a flashlight with the same luman output - the lantern lights up the area in all directions with itself in the centre, and the flashlight only lights up one specific area, what you will see is that the flashlight can light up the one direction brighter and further despite the output power being the same as the lantern.

You can detect things well enough if they are transmitting, but if you send a short encoded message and it is not long enough to brute-force attack it, then unless you just get crazily lucky, you can only DF where the signal is coming from, not actually decode it. One of the most amazing bugs was the one on the United States Seal - just a stunningly beautiful piece of presicion engineering which (I think) worked on a GDO basis where the audio in the room would alter the resonance of a little chamber - which then interferred with an RF beam squirted in from the building over the road. Depending on how the resultant signal was being affected (basically modulated), they could re-build it to get audio. Yet the device never really transmitted, it just "interferred" with an external signal. Clever little thing :)

You jest, but a pair (or single) copper wire from your house back to the exchange typically survived DECADES and just carried on working. Might get a bit crackly from time to time and so on, but ultra simple and ULTRA durable. Power cut? HomePhone still working just fine. Local mast damaged / maxed out - HomePhone still works. Dropped your handset - Homephone don't care. Drop it, stand on it, drive over it - probably still giving you a dialling tone. Good for about 60 years before you might want to replace it (for a nice new colour). The old stuff just worked - basically forever. Modern Phones with their "designed to fail", glass screens and microlife batteries are great while they work - but if you NEED to have a phone that is guaranteed to work - the old housephone probably won't let you down from one decade to the other. Can you say that about the latest plastic delight people pay over £1000 for ?

Old Radio guy for the military. Radio waves can penetrate nonconducting materials, such as wood, bricks, and concrete, fairly well. They cannot pass through electrical conductors, such as water or metals. Above ν = 40 MHz. Ya I took this from Britannica because I didn't want to type it out, long story short that's why you can get though multitudes of buildings and dense woods but struggle on a lake or beach. Ground radio waves also project in a curve (this is why they bounce off the water so quickly) so no joke you grab a 6-20ft antenna to any of these or even build a permeant housing and this could be broadcasting for miles.

​@@killerdeamonking Ok so not all long range (lora) are tied to GPS modules they are the same as any other transceiver technology. They use a bandwidth that used to be used for analog television signals. As for encryption that happens before anything is transmitted it's not a VPN tunnel it's not being encrypted by the antenna. And sure you can triangulate any rf signal and you can capture or intercept it but if encrypted it's still just going to be a garbled mess without the proper encryption key.

It spent hours at around 105,000’ and provided a relay footprint of almost 400 miles. 3 channels of VHF and 4 channels of UHF. While I put our contact info on the payload it’s never been returned so there’s some cool tech probably hung up in a tree in Eastern Kentucky.

@Sky_Dave 24 дні тому
The orientation of the antennas is also a key factor often times overlooked in RF transmission from these sorts of projects. Radio Waves in a whip/stub antenna are polarized either horizontally or vertically depending on the direction the antenna is oriented in relation to the surface of the Earth. If the antenna is held upright and pointed skyward the direction of propagation of the radio waves with respect to the Earth's surface would be horizontal. If the orientation of the other antenna is laying flat as opposed to standing upright, there will be a signal loss of 20dB due to polarization mismatch. This is an almost total loss of signal strength. Maximum signal strength occurs when the transmitting antenna’s polarization matches the receiving antenna’s polarization. When a polarization mismatch occurs in a linearly polarized antenna the entire signal will be lost due to the misalignment. This is probably best demonstrated using the picket fence analogy. A signal passing through a linear polarizer is much like a rope passing through a picket fence. As long as the oscillations of the rope are in line with the fence pickets, the oscillations can pass through the fence to the other side. If however, the fence was rotated 90 degrees, the oscillations of the rope would impact against the pickets and the energy and motion of those oscillations could not pass through to the other side of the fence. Effectively the “signal” has been cut off. -20dB is a notional value. In theory, all power should be lost during this conversion. But we are not living in a perfect world and some power will always go through.

Esp32 just doesn't handle that much processing required for large data transfer. So you can have plenty of signal strength but the bandwidth is still rather limited by the hardware. I know because I did this exact thing by modifying vanilla ad hoc mesh network libraries about four years ago. I was able to get live video across five nodes at around 60 to 70fps reliably over about 600 meters open area. But I had to modify and shorten the data protocol and switch to hex basically shorthand UDP it otherwise it just wouldn't handle it. And it only works to increase bandwidth by making a master and a slave endpoint who's sole purpose is to break up shorthand address and reassemble data packets. And only then you get more bandwidth according to the amount of nodes used and data packets sent at once. But as you scale up you get to store those pipe addresses on each device. And it quickly becomes an issue of node redundancy from the master's max data packets released at once. Or if you prefer a matter of each devices routing processing time effectively it becomes not worth it to add anymore nodes. At that point it makes more sense to just go with a single industrial solution. Now if your expectations are to send or stream single videos text messages or an array of integer data from sensors sure this will be fine. But if you're expecting to send several large files and simultaneously receive another file with any haste then no it simply isn't worth the hassle.

The Heltec device has rather limited transmitting power. The LilyGo/TTGo and others with the Semtech SX1276 transceiver have much better output. Off course they drain the battery faster, but it's worth the trade-off as very little time is spent transmitting. A potential downside of using a mesh network is the increased radio traffic. The protocol has to be finely tuned and possibly coupled to a GPS to minimize unnecessary traffic, so it would make more sense to use peer-to-peer until the signal starts to get weak.

We travel in an RV and end up in remote areas with no cellular service. This device has some potential use but also has limitations compared to the competition used in our situation. We use Zoleo for emergency coverage in non-cellular conditions. It uses the satellite network. It has the same concept with a small device that has an app tied to it for messaging and sending an SOS. It's advantage is that it uses and established network (satellites) where these LoRa devices require a mesh of users within range. I suppose if you only wanted to communicate with a single person then these are a glorified 2-way system. The downside of the Zoleo system (and Motorola or Garmin has a similar system) is that they do have a subscription fee. WE only activate the Zoleo subscription when we need to use it on a month-to-month basis so the cost is not a deal breaker for us. For travelers to remote regions, I don't see this LoRa system taking hold until there was a saturation of devices in remote areas.... I don't see that happening.

The current configurations are excellent demonstrations for introducing the use of a separate mesh node network through the integration and use of two standalone handheld devices. The appropriate next step from a hardware and software and utility perspective would be tighter integration. I also believe that one of the key value propositions is that the hardware is not fully integrated with existing mobile communications systems. A sleeve concept maintains the benefit of keeping hardware separate while improving handheld efficiencies.

On receive end, once you have enough gain to raise the signal above the receiver’s internal noise floor, there is no improvement. The only way good antennas help on receive is if they are directional, so they don’t include interference from all directions….of course you then have to know where to aim. Of course if you are running duplex or half duplex, then both ends will want good antennae…though if one direction is just handshakes you could maybe lower data rate on the acknowledgement replies to compensate for a wimpier antenna.

By the way, with a gmrs, a cellphone no longer in use but still sitting around and a downloaded program you can do the same thing and send it further over repeaters. No, it's not encrypted but it's the same concept and you don't need a cellphone that is connected. I have my "old" 5 to 6 year old smartphone that I HAD (now THAT'S a scam) to replace and it's VERY useful untethered to the cell providers.

With some tweaking this is a very interesting bit of tech. I imagine it would be put to better use in a larger form factor that has more signal power output and some kind of ATAK phone board depending on use case. As is it looks great for shorter distance comms where you don’t want to yell and FRS handhelds aren’t reliable. Nodes could also be discreetly placed ahead of time to build a temporary local network.

@Data Slayer If you can get your node outside of your apts tinted windows you will probably pick up more range. Its pretty common for commercial tinted windows to have a metalucized coating in the tint to reduce infrared & uv penetration into buildings. It does a pretty good job of attenuating radio signals, Also nano vna are pretty cheap check your antennas to make sure they are as advertised. AFAIK those stubby antennas ship for every country but I think they are better for 400 mhz which means you are wasting precious power heating up your heltec with a mismatched antenna. These radios use low power so having a matched dipole or yagi is going to give the best results. Whips are compact but best results with a balanced antenna and same polarization for both antennas.

although the problem is unknown, it makes it more efficient to solve that unknown problem. I do not know of a comm's problem that hasn't been solved using RF or industrial comm's technology........ PLC's/computers communicating thru spread spectrum transceivers, 'shortwave' for long distance comm's. I note that this is for a personal radio system in the 94x Mhz area.... they are inherently a short distance product anyway. But it is interesting to experiment with them and see what is possible. The aerial makes a lot of difference with that frequency. But it depends on the application if you can take advantage of directional aerials. If you are on the move... well you can't. Any application requiring mobile comm's is inefficient as normally an omnidirectional aerial is used, unless you go to Satellite repeaters (Starlink etc) , but then you still need a fixed dish somewhere close to do that....

That's not going to work very well you can't just ospf it like regular router protocol. Because to essentially ping nodes of these devices constantly for availability eats up more time and resources. And keeping track of available nodes in real time is more difficult because you're essentially using the same single resources to do so. It's much easier to just use the exact same pipe address for nodes within a distance range and transmit to all and any available nodes. Then you repeat in whatever direction you are going. You program the endpoint to reassemble packets based off however many packets you programmed to be distributed by the master. And numbered in a rolling integer based on your estimated network size, data transfer size, and average hop between distance segments. When it's broken up by the master it's assigned a rolling number as a bit, a direction bit, a segment bit, and a max segment bit. You can reprogram the transfer protocol to use hex to tokenize or compress those values into half as many. Creating essentially the address header and reassembly instructions in one. At each distance segment only the direction bit is overwritten according to it's opposite. If you were going to incorporate an omnidirectional mesh network then you might want to assign each node an integer index as a replacement to direction bit with some incrementing or cartesian organization. At the endpoint it discards the direction bit reads the rolling number the segment and max segment bits. The rolling number assigns the overall data being sent the segment assigns the data packet number and max segments assigns the total packets. It's then programmed to assign that data to a stored variable (if then) to organize and also drop any redundant incoming packets from the same rolling number. Ie. read max segment read segment assign 1 to variable segment 1, 2 to segment 2 ect. If equals to packet number received then increment to a received variable or sent variable depending on which is happening. If sent or received variable does not match close pipe drop packets. Print or store segment variables.

@@CharltonJude - The FCC, federal communication commission regulates what frequencies can be transmitted on, with what power, and by whom. For example, you can't just start a radio station in your backyard by hoisting up an antenna and broadcasting. There are certain transmissions that are allowed without approval, such as citizen's band radio and the devices listed here. Anyone can grab one and start transmitting. HOWEVER, those devices are limited in the power they can transmit with on those approved frequencies. If you turn the power up, the devices can interfere with other signals or electronics. A boosted CB radio will actually bleed over into a TV or a radio that's close enough, for example. In order to boost the range of this device, you'd need to increase the transmit power. Increasing the signal power will boost range. That's the "broadcasting range" I mentioned. Increasing the transmit power isn't allowed and could draw complaints from people nearby because it's a violation of the FCC rules and could end up in fines and orders to stop using the equipment. That's the "FCC issues".
