It should be used as such: Encourage as many people as possible to install in their attic for low cost. A small solar panel and lithium battery will allow the network to remain in place in power outages. Joining the mesh will allow access to the mesh. The mesh will carry encrypted data from users on the network. Encryption keys will be used like phone numbers. Individuals may communicate outside normal networks, with strong encryption preventing the ability of government snooping or censorship. Yes government tyrants, I'm talking about YOU.

The great performance of LoRa in all these 3 features (good sensitivity, low path loss, good obstacle penetration) makes LoRa a disruptive technology enabling really long range links. This is specially important in urban scenarios, with very difficult transmission conditions. To sum up, LoRa can get long ranges in Smart Cities deployments, so it reduces dramatically the size of the backbone network (repeaters, gateways or concentrators).

[@richtaft3308]

I've worked with LoRa before in a master to multiple slave type scenario. The amazing thing is you're only transmitting about 20mW. This is a variation of DSSS and due to the orthogonal signal spreading, the receiver can pick the signal up below the noise floor. I have been able to get up to 2 miles with the Multitech module. With a 1 watt FHSS module on the same band, with the same antenna, I get about half that range. Not all modules get the same range with the same settings. The Atmel version I tried didn't go nearly as far with the same settings. Atmel didn't know why. A node up on the roof or a pole with a better antenna should go really far.

Really good basic review. These devises are quite interesting.

Being a 915 MHz, there shouldn't be many other radio devises to interfere with their use. More than one group can be in the same area and separate from what I hear. Lots of potential uses. Grid/cell phone down, these will keep you connected with others in your area as long as you have a way to keep the battery charged...think solar.

[@jakegarrett8109]

Time to buy some. I don't know how you've survived without basic tool like that (I use it more than a hammer, most people own hammers). Even a cheap 40-60w rated one for $5 will be plenty for this and lots of projects, just practice on some dead electronics first and this will be easy. You could spend more (like mine is a nice one, I've went through a few cheap $3 to $5 ones through my lifetime but since I use it often I spent the cash and got a really nice $70 one that has both the soldering as well as a hot air rework on it with diaphragm pumps so I can do more advanced things like GPU core repairs and tiny SMD parts 1/5 the size of a grain of rice if needed (which in that example was bypassing the stupid timer on a heated blanket that would shut it off every 3 hours so you'd wake up at least twice freezing cold every night and never get a good night's sleep, but disable it's timing circuit by removing one part and perfect! Saved about $40 compared to their "pro model" which is the exact same thing as what I did). Also helpful for other improvements, like a simple solder mod almost doubled the power on my ebike (shunt mod, I noticed the transistors we're rated for 70 amps so I bumped it from 20 amps up to 35 amps so I still have a huge safety factor but lots more performance). Or for computer parts I add voltage bypass controls or you can do shunt mods or other stuff if you're into performance gains. But even mundane stuff like soldering a battery pack or adding external devices or anything else (like my drill now uses my quadcopter and airplane batteries so one less battery to charge, or my shaver now uses higher power LiPo for faster shaving, or my calculator now uses cell phone batteries). Also may need to solder the solar panel to the LoRa (I've also made my own solar panels from raw cells). I also use soldering a lot for fixing vehicle wiring, and really I don't know how you've survived this long without one, lol!

It sounds very low bandwidth, but I too was hoping to hear this info :/

[@DJ_Megahertz]

Very little. Just enough to send a few messages.

Been waiting for a device like this.

I can see a lot of potential for this type of mesh capabilities.

[@freedog632]

This could be good on the long trails like AT. A hiker that gets lost, and has something like this, could greatly increase their chances of rescue.

[@isaacfulton7731]

Probably not better than an emergency beacon radio. But cool for communication with a group

[@blagsreport4763]

Thought the same!! If hikers all grabbed one it would create a usable mesh on busy trails. Save a fortune on subscriptions to emergency GPS systems that are never used and provide hiker to hiker warning system for trail issues... ie. blocked trails or bear sightings 🐻

For a Prepper neighborhood for SHTF, this technology might be very important when the grid goes dark. With God's help maybe we will not see the need but just in case a family of the close neighborhood, possibly coming together in a rural location this could be a key? Of course, Ham and CB could be there to use but still simple text messages to the community might be well served. Being Solar is also a great benefit.

indeed. just tested similar system, had no problems reaching all five receiver stations and all were at least 10 miles apart from central node. will upped the range and test again in a week or so. love the concept.

This is awesome. Thank you.

“that would give away my location” Isn’t your call sign, that you have publicly available on discord, tied to your address?

[@cdorcey1735]

That's the address that the FCC can send official communications to. Not necessarily where he currently lives.

[@Jody_VE5SAR]

I think both your tablet and phone were both associated with the same device (node 954c), no? So the test message was sent just by bouncing through 954c, and not over LoRa. The fact that the T-Beam's both showed the message indicates they were paired though, so it did have a mesh, you just weren't passing your message over it.

[@HamRadioCrashCourse]

Nope. They were connected to their own tbeam.
