 | 
						||
<p>One of the truly valuable aspects of Reticulum is the ability to use it over
 | 
						||
almost any conceivable kind of communications medium. The <a class="reference internal" href="interfaces.html#interfaces-main"><span class="std std-ref">interface types</span></a>
 | 
						||
available for configuration in Reticulum are flexible enough to cover the use
 | 
						||
of most wired and wireless communications hardware available, from decades-old
 | 
						||
packet radio modems to modern millimeter-wave backhaul systems.</p>
 | 
						||
<p>If you already have or operate some kind of communications hardware, there is a
 | 
						||
very good chance that it will work with Reticulum out of the box. In case it does
 | 
						||
not, it is possible to provide the necessary glue with very little effort using
 | 
						||
for example the <a class="reference internal" href="interfaces.html#interfaces-pipe"><span class="std std-ref">PipeInterface</span></a> or the <a class="reference internal" href="interfaces.html#interfaces-tcpc"><span class="std std-ref">TCPClientInterface</span></a>
 | 
						||
in combination with code like <a class="reference external" href="https://github.com/simplyequipped/tcpkissserver">TCP KISS Server</a>
 | 
						||
by <a class="reference external" href="https://github.com/simplyequipped">simplyequipped</a>.</p>
 | 
						||
<p>While this broad support and flexibility is very useful, an abundance of options
 | 
						||
can sometimes make it difficult to know where to begin, especially when you are
 | 
						||
starting from scratch.</p>
 | 
						||
<p>This chapter will outline a few different sensible starting paths to get
 | 
						||
real-world functional wireless communications up and running with minimal cost
 | 
						||
and effort. Two fundamental devices categories will be covered, <em>RNodes</em> and
 | 
						||
<em>WiFi-based radios</em>.</p>
 | 
						||
<p>While there are many other device categories that are useful in building Reticulum
 | 
						||
networks, knowing how to employ just these two will make it possible to build
 | 
						||
a wide range of useful networks with little effort.</p>

<div class="section" id="rnode">

<span id="rnode-main"></span><h2>RNode<a class="headerlink" href="#rnode" title="Permalink to this headline">¶</a></h2>
 | 
						||
<p>Reliable and general-purpose long-range digital radio transceiver systems are
 | 
						||
commonly either very expensive, difficult to set up and operate, hard to source,
 | 
						||
power-hungry, or all of the above at the same time. In an attempt to alleviate
 | 
						||
this situation, the transceiver system <em>RNode</em> was designed. It is important to
 | 
						||
note that RNode is not one specific device, from one particular vendor, but
 | 
						||
<em>an open plaform</em> that anyone can use to build interoperable digital transceivers
 | 
						||
suited to their needs and particular situations.</p>
 | 
						||
<p>An RNode is a general purpose, interoperable, low-power and long-range, reliable,
 | 
						||
open and flexible radio communications device. Depending on its components, it can
 | 
						||
operate on many different frequency bands, and use many different modulation
 | 
						||
schemes, but most commonly, and for the purposes of this chapter, we will limit
 | 
						||
the discussion to RNodes using <em>LoRa</em> modulation in common ISM bands.</p>
 | 
						||
<p><strong>Avoid Confusion!</strong> RNodes can use LoRa as a <em>physical-layer modulation</em>, but it
 | 
						||
does not use, and has nothing to do with the <em>LoRaWAN</em> protocol and standard, commonly
 | 
						||
used for centrally controlled IoT devices. RNodes use <em>raw LoRa modulation</em>, without
 | 
						||
any additional protocol overhead. All high-level protocol funcionality is handled
 | 
						||
directly by Reticulum.</p>

<span id="rnode-creating"></span><h3>Creating RNodes<a class="headerlink" href="#creating-rnodes" title="Permalink to this headline">¶</a></h3>
 | 
						||
<p>RNode has been designed as a system that is easy to replicate across time and
 | 
						||
space. You can put together a functioning transceiver using commonly available
 | 
						||
components, and a few open source software tools. While you can design and build RNodes
 | 
						||
completely from scratch, to your exact desired specifications, this chapter
 | 
						||
will explain the easiest possible approach to creating RNodes: Using common
 | 
						||
LoRa development boards. This approach can be boiled down to two simple steps:</p>
 | 
						||
<ol class="arabic simple">
 | 
						||
<li><p>Obtain one or more supported development boards</p></li>
 | 
						||
<li><p>Install the RNode firmware with the automated installer</p></li>
 | 
						||
</ol>
 | 
						||
<p>Once the firmware has been installed and provisioned by the install script, it
 | 
						||
is ready to use with any software that supports RNodes, including Reticulum.
 | 
						||
The device can be used with Reticulum by adding an <a class="reference internal" href="interfaces.html#interfaces-rnode"><span class="std std-ref">RNodeInterface</span></a>
 | 
						||
to the configuration.</p>

<p>To create one or more RNodes, you will need to obtain supported development

boards. The following boards are supported by the auto-installer.</p>

 | 
						||
using the <a class="reference external" href="https://github.com/markqvist/rnodeconfigutil">RNode Configuration Utility</a>.
 | 
						||
Make sure that <code class="docutils literal notranslate"><span class="pre">Python3</span></code> and <code class="docutils literal notranslate"><span class="pre">pip</span></code> is installed on your system, and then install
 | 
						||
the config utility with <code class="docutils literal notranslate"><span class="pre">pip</span></code>:</p>
 | 
						||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">pip3</span> <span class="n">install</span> <span class="n">rnodeconf</span>
 | 
						||
</pre></div>
 | 
						||
</div>
 | 
						||
<p>Once installation has completed, it is time to start installing the firmware on your
 | 
						||
devices. Run <code class="docutils literal notranslate"><span class="pre">rnodeconf</span></code> in auto-install mode like so:</p>
 | 
						||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">rnodeconf</span> <span class="o">--</span><span class="n">autoinstall</span>
 | 
						||
</pre></div>
 | 
						||
</div>
 | 
						||
<p>The utility will guide you through the installation process by asking a series of
 | 
						||
questions about your hardware. Simply follow the guide, and the utility will
 | 
						||
auto-install and configure your devices</p>
 | 
						||
<p><strong>Important Note!</strong> It is currently recommended to use the v1.x line of the RNode firmware,
 | 
						||
even though the v2.x line is available for early testing. The v2.x line should still be
 | 
						||
considered an experimental pre-release. Only use the v2.x firmware line if you want to test
 | 
						||
out the absolutely newest version, and don’t care about stability.</p>

<h2>WiFi-based Hardware<a class="headerlink" href="#wifi-based-hardware" title="Permalink to this headline">¶</a></h2>
 |

<p>It is possible to use all kinds of both short- and long-range Wifi-based hardware
 | 
						||
with Reticulum. Any kind of hardware that fully supports bridged ethernet over the
 | 
						||
WiFi interface will work with the <a class="reference internal" href="interfaces.html#interfaces-auto"><span class="std std-ref">AutoInterface</span></a> in Reticulum.
 | 
						||
Most devices will behave like this by default, or allow it via configuration options.</p>
 | 
						||
<p>This means that you can simply configure the physical links of the WiFi based devices,
 | 
						||
and start communicating over them using Reticulum. It is not necessary to enable any IP
 | 
						||
infrastructure such as DHCP servers, DNS or similar, as long as at least Ethernet is
 | 
						||
available, and packets are passed transparently over the physical WiFi-based devices.</p>

Reticulum links over long distances:</p>

<p>This list is by no means exhaustive, and only serves as a few examples of radio hardware
 | 
						||
that is relatively cheap while providing long range and high capacity for Reticulum

networks. As in all other cases, it is also possible for Reticulum to co-exist with IP

<p>It is useful to combine different link and hardware types when designing and

building a network. One useful design pattern is to employ high-capacity point-to-point
