Bravo dude. Each update it makes it harder for me to decide what i should order from you
Accessories IP/Lora Mesh/ATAK/Off-grid encrypted comms device
- Thread starter Bilb0
- Start date
Thank you
These will have hardened 12gb galaxy s20+ smartphone ATAK option with zero kinks.
ATAK FDE version with External GPS and Bluetooth antenna. All high end certified parts and connectors.
Will soon have an upgrade for these that will have high power "encrypted" data; video, voice and text, off-grid maps.
These will push encrypted megabits not bytes being LoRa's limitations.
Streaming hd video, voice won't be over low power Lora/Meshtastic so the range and clarity will be excellent and range will not be limited. I would like to keep the Lora meshtastic setup, not necessary but for fun and redundancy. Theyll work simultaneously.
Range on the streaming video, voice, data etc will be typical range of previous devices but with 30-50 mile range do-able with clear line of and proper solar repeating nodes in place to alleviate interference from obstructions or foliage if need be. I'm working on a 100 mile setup currently. These will work in ATAK as usual. You could prob play games with each other on your smartphones during the apocalypse if you wanted.
650 per device for basic Lora Meshtastic setup as pictured. External GPS is an additional 100. The IP mesh upgrade with Streaming video, voice, chat etc will be additional $200. Obviously I could ask for way more but that's not my goal.
I have a USB connector option for the military grade Amphenol socaplex ratcheting USB setup for charging the EUD smartphone device; utilizing the 18650 power bank. But they run $200. Not necessary but an option for anyone wanting to go all out.
These radios are designed for the N type mil spec goosneck antennas but they do run around 250-$350 at a few places online. I can direct you to those sources if you want to purchase them. I can't afford to have many of those laying around at the moment.
I include a SMA gooseneck antenna and adapter that works perfectly fine. But know the option is there.
These will have an upgrade to the 18650 battery bank for quick change if you don't want to mess with swapping them out individually.
I do have them designed and setup for the expensive stuff. My goal is provide everyone with top knotch quality thats actually affordable but with the option to go all out like we do with our rifles.
These aren't cheap to make so I don't have tons of parts to have many of these on hand ready to sell. I currently have to fulfill requests until that's possible. Just shoot me a message if interested.

Blacked out Lora/Meshtastic version with External GPS and the Amphenol Socaplex USBFTV EUD 5v power hub, wired to power all Apple devices as well. Amphenol ip68 Switches etc. 14k mah Molicel p28a 18650 swappable power bank. Redundant Touchscreen. And Samsung S20 running meshtastic and ATAK connected to radio via Bluetooth.
I haven't the slightest idea what any of that is or does or how it works but it's damn awesome
Thank you
I appreciate your comment. This made me realize I need to sit down and think of a way to explain these; and show how simple they actually can be to use. Within the next week, the new boards should arrive; which will allow these to have streaming video, voice and chat capability. Fully encrypted. Off-grid. That will probably be the easiest time to do the full blown breakdown.
Beast mode top complete. Amphenol Type N Antenna Studs for the MIMO Video/Voice/Data comms.

Upgrade: Twist on battery flywheel assembly. Debating on allowing the radio to use off the variable voltage 6-24v off shelf prc-148/prc-152 batteries.
Yeah I'm pretty passionate with my developments they tend to escalate quick lol. I'm currently finishing up this latest device; which can be simplified but Ill send you a message to get which specific device you had in mind. I typically don't have parts on hand for the older device designs, they'd have to be ordered. Thank you for your complements and reaching out.
Could I get model/price breakdown. I have 2 base Lora boards I set up, but nothing to this scale and having access to equipment to make anything like this.
Did a little remix on the current version to tidy things up with the new upgrades.

Update:
When any smart device ( ATAK app installed) is connected to the encrypted network of these mesh radios; they will automatically sync with ATAK. ATAK will sense this and give full multicast functionality. I did not have to make a single settings change in ATAK , the GPS and device becons populated and I could instantly chat, send files and high res images. There is a push to talk plugin for ATAK to setup voice comms I haven't tinkered with.
I downloaded a simple offline communication app that allows the typical hd voice calling and messaging to any device that connected to mesh radio. Video calling would work the same. Literally takes zero user experience.
You can connect IP cameras to these radios, drones supplying video feed etc.
These have a built in Lora chipset /GPS/Meshtastic. Middle antenna. Same technology Ive described in all past posts of the previous Lora devices. It's a nice quality chipset for redundant low power encrypted communication.

Extra info:
The L3 Harris Prc-152a twist on battery; supplys power to Persistent systems 3 pin battery flywheel which supply's power to 6-21v variable voltage input of the 5 Ghz MIMO IP Mesh radio. The 915 mhz Rak Lora Module with GPS piggy backs off the power supply.
You can use off the shelf prc-148 or prc 152 battery's ranging from 6-21v. I'm using Harris batteries due to the quality of internal battery management system circuitry. Rebuilding them with 6x Molicel 18650s, which I've found to be the best rated for the type of discharge curve I desire.
Off the shelf L3 Harris, Thales, Bentronics prc-148 and 152 batterys are 4-8 amp hour, $350-1400 each. It may take two batteries to have the radio work all day depending on how many hours you look to run the radios. Some batteries are charger specific so keep that in mind.
I include a L3 Harris OEM charger with the one L3 Harris battery I supply per radio.
There are prc 148/152 batteries that have swappable Cr123 or AA options which is interesting. These radios can be powered by those as well.

Information to help simplify the understanding of the technology being used.
These radios run two networks simultaneously; An encrypted 5ghz MIMO MANET IP Mesh Radio Network and 915Mhz Lora radio network
Description below:
Introduction to MANET
Stream voice, data and video via an “infrastructureless” network
Infrastructure-based systems that use as cellular or WiFi technology utilize a central ‘hub’ node to deliver high speed connectivity and good Quality of Service (QoS) to the user. Removing this infrastructure and adding mobility, coupled with time varying connectivity profile without adversely affecting the user’s QoS is the formidable challenge faced by developers of Wireless Mesh Networking (also called MANET, or Mobile Ad hoc Networking) systems.
A MANET system is a group of mobile (or temporarily stationary) devices which need to provide the ability to stream voice, data, and video between arbitrary pairs of devices utilizing the others as relays to avoid the need for infrastructure.
There are many techniques which are employed in order to provide robust MANET capability, including the following:
Self-Forming / Self-Healing
Self-Forming / Self-Healing is a crucial characteristic of MANET systems. In a true mesh network, radios can join or leave the network at any time, and the network will continuously adapt its topology as nodes move in relation to one another. This implies a decentralized architecture in that there are no central “master” hub radios required to administer control of the network, and communications will continue to persist even when one or more nodes are lost.
Link Adaptation
Link Adaptation is the ability for each radio to optimally configure its transmission parameters (constellation, FEC coding, and MIMO techniques) to maximize the data rate and robustness of the links to each of the other radios it is communicating with. A particular radio may communicate with another close by radio using a data rate of over 50 Mbps, while using a rate of only 2 Mbps to provide a robust link to a radio much further away. These are packet burst rates, where using a 50Mbps burst is very useful even for a much lower rate data stream because it leaves free channel airtime for other nodes in the network to use. Having high potential data burst rates is important because the less airtime is consumed for the shorter links, the more airtime is left to use slower and much more robust modulation and coding on the distant links.
Adaptive Routing
Adaptive Routing is a mechanism for determining which potential relay paths are used when a stream of data needs to be sent between a given pair of radios. It needs to support self-forming self-healing functionality by adapting dynamically to use all radios present as potential relays and be resilient to the loss of relaying radios. It must also work in conjunction with the link adaptation because determining the optimal route for a stream of data requires consideration of other data which is flowing through the network, as well as the dynamic capacity of each link within the network. This problem is complex and requires all radios to share information about the data traffic flowing through them and the link capacity from each to the other neighboring nodes. This sharing of information must be done in an intelligent manner so that it does not consume too much of the precious available network throughput.
Transparent IP Networking
Transparent IP Networking means that any number of standard computer, IP video camera or other devices may be connected to each of the mobile radios and communicate through the mesh network just as if all of the devices were in a single office with wired Ethernet. There are different ways this can be accomplished within the MANET. To enable the most flexibility and ease of use, the best choice is to have the entire MANET network appear as if it is a single Layer 2 networking switch. This means that without any reconfiguration of IP addresses or other settings, a group of IP-based devices that work together on a simple Ethernet switch can be connected to MANET radios and resume operations with the new freedom of wireless mobility.
Multicast Traffic
Multicast Traffic presents a set of unique challenges for MANET systems. The multicast support implemented in basic wired Layer 2 switches is to replicate multicast packets coming into one port on all of the other ports. For instance, if an IP video camera is connected to one port it would send its video using packets tagged as multicast. Then computers wired to any of the other ports of the switch can tap into the wireless video stream. This simplistic method turns out to not work very well in a wireless network acting as a Layer 2 switch because many devices within the network might not need to see a particular multicast, and blindly sending the multicast to all devices thus congests the limited throughput of the wireless network unnecessarily. More advanced MANET systems allow manual and/or automatic optimization, limiting the transmission of multicast to only those devices that need a particular multicast stream.
Multi-channel Networks
Multi-channel Networks is an advanced capability of some MANET systems which allows a network to utilize multiple RF channels or even multiple frequency bands within a network while still providing the plug and play functionality of a single Layer 2 switch. A simple example of the usefulness of this might be a scenario where soldiers have radios operating on one frequency while vehicles have radios not only operating on that frequency but also ones in a different band. This additional band might be with higher power or higher gain antennas to provide a high speed “backbone” layer between the vehicles. Any soldier’s radio device can communicate with any other soldier’s radio over the air, but the secondary layer on a different frequency can reduce congestion on the soldier frequency and increase to area covered by the network.
All of these MANET networking capabilities combine to provide robust high speed connectivity similar to what is offered by state of the art 3G/4G networking, but in mission critical operational scenarios where permanent wireless infrastructure is not available.
Added Lora Redundant network:
Lora Mesh Radio Technology Description:
LoRa operates in the US between 902-928 MHz.
LoRa stands for “Long Range” and it is a mesh network that uses low power, and wide area networking protocols. LoRa does not require internet, wifi, or cellular and is OFF GRID.
What is LoRa MESH?
LoRa MESH is a self-organizing network communication protocol based on LoRa technology. It utilizes LoRa wireless communication technology to form a self-organizing network with multiple devices, creating a mesh topology to achieve interconnection between devices. It combines the advantages of LoRa technology with the characteristics of Mesh self-organizing networks.
Self-Organizing Network Features
LoRa MESH networks have self-organizing features, automatically building and maintaining networks. When devices join or leave the network, the network automatically adjusts its topology to ensure the stability of data transmission. This self-organizing feature provides LoRa MESH networks with high flexibility and scalability.
Multi-hop Transmission:
LoRa MESH networks use multi-hop transmission, where data can be relayed through multiple nodes before reaching the destination node. This multi-hop transmission effectively extends the communication distance, improves signal penetration, and reduces the communication pressure on individual nodes.
LoRa technology: low power consumption, long distance, anti-interference
LoRa is a linear frequency modulation spread spectrum IoT modulation technology, also known as broadband phenomenon FM (Chirp Modulation) technology. Compared with the traditional FSK technology, LoRa has a longer transmission distance under the same power consumption, and has strong anti-interference ability.
Wireless module with low power consumption
The application of the LoRa module is generally the Internet of Things devices, usually powered by batteries, and the use time is more than a few years, which requires the LoRa module to have extremely low power consumption. The low power consumption of the LoRa module is mainly determined by two aspects: The wireless module chip needs to have low power consumption; and the software communication protocol also needs to have low power consumption.
The power consumption of the Lora Module is very low.
In terms of software communication protocols, LoRa does not have complex communication protocols like other wireless technologies. The data packets are very simple, and there is no need to send a large amount of handshake data. In order to achieve the purpose of saving power, the industry widely uses the Wake on Radio (WOR) method.
The LoRa chip enters the receiving (RX) mode periodically to listen to whether there is a wake-up preamble, and is in the sleep (Sleep) mode at other times. Most of the time it is in sleep mode, and only a small part of the time is woken up in receiving mode, so its overall power consumption is very low.
Communication anti-jamming
The LoRa module can realize long-distance data transmission. In addition to the sensitivity advantage, another very important factor is the super anti-interference ability. LoRa can still communicate when the noise is lower than 20dB, which is not available in existing traditional communication technologies.
LoRa can normally demodulate the signal 20dB below the noise, while FSK theoretically needs to be 8dB above the noise to ensure demodulation. When the communication process encounters external electromagnetic signal interference, LoRa can continue to communicate stably, while traditional wireless technology cannot communicate. Therefore, in some areas with serious channel interference, customers will choose LoRa technology as the core technology for stable communication.
A new method of low power encrypted communication; unitizing LoRa hardware with Meshtastic firmware.
Meshtastic provides AES256-CTR encryption for the payload of each packet when sending via LoRa with a different key for each channel.
Alice and Bob can be individuals or groups, Alice and Bob can set up a Off-grid Mesh communication system for their use that has the following characteristics:
Allows both real-time and asynchronous communication between Alice and Bob.
Works completely independently of any infrastructure outside the control of Alice and Bob. Even if the Internet, cellular networks and the power grid fails, Alice and Bob must still be able to communicate.
Is completely private and outside the reach of automated surveillance, and does not reveal any identifying information about Alice or Bob, nor any contents of or information about their conversations.
The system can be expanded to provide these opportunities to an entire community or communities.
Drone repeaters or temp/stationary solar repeaters can be launched to provide extended range through a fresnal zone or obstructions from elevation.
Very stable Direct PTP links can be setup as a automatic bridge in the mesh network to get 50-100 mile range to another town or location. Powered by a simple solar setup to be consistently active during temp/indefinite power outage.
**Manet and IP Mesh explanation was pulled from _Silvus_Radios due to their excellent description.
Device networks pre-setup and auto configured. Simple power button, wait 60 seconds and connect smart device to the Mesh devices wireless encrypted Network.
Using Jami Android/iOS app to be downloaded for encrypted voice, video, file and messaging chat.
Use ATAK Android/iOS app for offline high res map or multicast abilities etc.
Use Meshtastic Android/iOS app for simple extended encrypted GPS/ Lora messaging ability.
Currently building per request until I have the ability to stock enough inventory.

Foxhunt or local POTA and home base testing of equipment.
Based on what I can see on the antennas, it could be either seeking a problem signal generator/annoying actor or simply POTA in his local area VHF/UHF.
And/or testing the range of his equipment back to his station a known distance away for various reasons.

This week I crafted an idea. Same hardware configuration in LoRa/GPS version. And SISO for the encrypted IP mesh/LoRa/GPS version; just small form factor, same power output. Have had a few inquiries pertaining to this, so I whipped one out. Believe it or not the small form factor is built like a TANK. At least Twice the density as the original form factor. Tough as nails. Will post the FDE version tomorrow.
Side note: A Mobile Starlink setup can be easily integrated into the network of the IP mesh radio version as well. Seamlessly
