It’s Been a Good Run, Phone Providers.

[@MrCharlieUK]

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.

[@DimMakTen]

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.

[@nolga3569]

great explanation, thank you for taking the time to write it up.

[@MrCharlieUK]

​@@DimMakTen 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.

[@marcogenovesi8570]

the low cost of these devices allows to deploy a ton of nodes though so yeah they can be tracked but it can become a pretty time-consuming job to root out hundreds of those hidden around or literally thrown off a plane/drone at regular intervals to maintain the network

[@fireandiron4181]

As a former Marine who did some pretty high tech training exercises that simulated Peer-on-Peer warfare, I will tell you that there is no way of radio or cellular communication that cannot be tracked. It can be encrypted, but there is no way to keep it from being tracked. That's why we practiced radio silence, and only turned them on as a last resort. If we used radios to communicate, we immediately abandoned our position, because within an hour there would be helos and jets circling where the transmission was detected.

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]

100% agree with you, Its not as secure as people claim to be or at all, It can be a good way to communicate in emergency situations for off grid uses or when networks are congested , but can easily be tracked because the Lora pings your GPS location when you communicate which you would know that can be traced through RF as well. Its amazing that people swear that its encrypted and is " Safe" , although still good to have for emergency uses.

[@fireteamomega2343]

​@@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.

[@Sky_Dave]

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.

[@kaiboshvanhortonsnort359]

Thanks, one would hope that an enthusiast that gets into radio communication of any kind will do the legwork - which most certainly needs to include a layman's understanding of how the physical size/length/orientation of antennas is absolutely critical to the process.

[@targetdreamer257]

How to you figure out which way your antenna is polarized?

[@fireteamomega2343]

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.

"Radio Frequency Propagation" is what many people need to study. It seems new to many people here, but these properties of radio propagation have been researched and known about for well over 100 years. Why does 934 Mhz work? Why doesn't it work? Learning about radio signal transmission (or Radio Frequency Propagation) will help if you're in this for the long haul. The software, the mesh etc are different topics. There are several layers to get thru with those higher frequencies .

Neat little solution. I'm having difficulty locating the problem it solves.

[@reedbender1179]

🤔🤣🤫

[@colonelfustercluck486]

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....

Thanks for sharing this information. Very well done and helpful. A couple things to consider. Refactor 3d printed mobile computing device plus mesh node housing in the form of various "sleeve" concepts to introduce the idea of more efficient integration and use of space. 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.

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 :)

[@baladithyabalamurugan3070]

how about this? use a Distributed Hashtable to keep track of network participants, then if the participant is on the network then estimate the fastest pathway of nodes and yeet the packets that way. if the participant is not on the network then yeet through a LORA/Internet Gateway bridge. architect the p2p connections similar to how a IPFS system is set up but with encrypted communication rather than data transfer. might provide better flexibility.

[@MilkyToucan]

Please expand on this

[@bsharper]

Not sure there would be much benefit, most DHT implementations would max out the throughput in Meshtastic most configurations. A big part of these devices as they are currently used is ephemerality.

[@fireteamomega2343]

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.

Or you could just, I don't know, push the transmit button on a walkie talkie or CB radio and be done with the whole thing. RF signals are pretty easy to encrypt as well if you really need it. You're just trying to re-invent the wheel and over complicating it. If it's not broken, don't fix it.

Gotta love the 21th century rediscovery of amateur radio. The modernised idea is cute, and the encryption is a solid upgrade, but the rest is like WW1-era technology at best.

Hezbollah was an unserious organization, which is why they never had defensive capabilities to protect all their missiles and installations from a clearly advanced foe. Very bizzare.

So it's like, a modern day pager?

[@JohnMcAfee-se9ms]

Without paying the telecom companies which always rate as one of the worst in customer support and satisfaction. More like an SMS device than pager.

[@JohnHPixelMD]

@@JohnMcAfee-se9ms More like a modern day text pager that you don't pay to use but instead have to pay for a bunch of devices to have a network setup that you can access and so can your family and friends...after you teach them how to make their own devices and setup their own networks and make sure their network and your network mesh together and service each device when components need replacing and repair devices that get damaged from weather and normal people walking by it and teach them how to connect it to their phones and then remind and re-teach them all of that again because they forget everything you taught them before a week after you taught them. Or you can pay a company to use their massive network which makes anything you could ever dream of engineering look like a child's toy in comparison and you don't even have to fix it or teach anyone how to use it! It's almost like paying for a service provides you with a easy to use simple service that anyone can figure out and use. Worried about big brother listening? Too bad, they've been listening for decades and know all about you already and if you think this is the only attack surface they are using to spy with then you are even more foolish than I initially thought.

People don't understand that the prices of things are never going back down, This inflation is deeper than we think. Those buying groceries are well aware that the real inflation is mych over l0%, The increments don't match our income, yet certain investors still earn over $365,000 in stocks and assets, Wish I could accomplish that.
