communicate with other Reticulum peers within your local broadcast domains.
To communicate further, you will have to add one or more interfaces. The default
configuration includes a number of examples, ranging from using TCP over the
internet, to LoRa and Packet Radio interfaces.
With Reticulum, you only need to configure what interfaces you want to communicate
over. There is no need to configure address spaces, subnets, routing tables,
or other things you might be used to from other network types.
Once Reticulums knows which interfaces it should use, it will automatically
discover topography and configure transport of data to any destinations it
knows about.
Possibly, the examples in the config file are enough to get you started. If

Adding Radio Interfaces

Once you have Reticulum installed and working, you can add radio interfaces with
any compatible hardware you have available. For information on how to configure
this, see the :ref:`Interfaces<interfaces-main>` section of this manual.

as interfaces with Reticulum. You can refer to the following external resources

implement the concept of *paths* that allow discovery of how to get information closer to a certain
destination. It is important to note that no single node in a Reticulum network knows the complete
path to a destination. Every Transport node participating in a Reticulum network will only
know what the most direct way to get a packet one hop closer to it's destination is.
.. _understanding-nodetypes:
Node Types
----------
Currently, Reticulum distinguishes between two types of network nodes. All nodes on a Reticulum network
are *Reticulum Instances*, and some are alo *Transport Nodes*. If a system running Reticulum is fixed in
one place, and is intended to be kept available most of the time, it can be a *Transport Node*, by enabling
it in the configuration.
This distinction is made by the user configuring the node, and is used to determine what nodes on the
network will help forward traffic, and what nodes rely on other nodes for wider connectivity.
If a node is a *Instance* it should be given the configuration directive ``enable_transport = No``, which
is the default setting.
If it is a *Transport Node*, it should be given the configuration directive ``enable_transport = Yes``.

As an example, in a network based only on radio transceivers with an average link distance of 15
kilometers, an announce will be able to propagate outwards over 12 hops, to a radius of 180

The design and constants of the decay and delay functionality in the announce propagation is subject
to change and optimisation as real-world usage is explored. The announce propagation speed can be
increased at the cost of increased bandwidth consumption.

Node Types

Currently Reticulum defines two node types, the *Station* and the *Peer*. A node is a *station* if it fixed
in one place, and if it is intended to be kept online most of the time. Otherwise the node is a *peer*.
This distinction is made by the user configuring the node, and is used to determine what nodes on the
network will help forward traffic, and what nodes rely on other nodes for connectivity.
If a node is a *Peer* it should be given the configuration directive ``enable_transport = No``.
If it is a *Station*, it should be given the configuration directive ``enable_transport = Yes``.

communicate with other Reticulum peers within your local broadcast domains.
To communicate further, you will have to add one or more interfaces. The default
configuration includes a number of examples, ranging from using TCP over the
internet, to LoRa and Packet Radio interfaces.
With Reticulum, you only need to configure what interfaces you want to communicate
over. There is no need to configure address spaces, subnets, routing tables,
or other things you might be used to from other network types.
Once Reticulums knows which interfaces it should use, it will automatically
discover topography and configure transport of data to any destinations it
knows about.
Possibly, the examples in the config file are enough to get you started. If
you want more information, you can read the :ref:`Building Networks<networks-main>`

Adding Radio Interfaces
==============================================
Once you have Reticulum installed and working, you can add radio interfaces with
any compatible hardware you have available. For information on how to configure
this, see the :ref:`Interfaces<interfaces-main>` section of this manual.
A range of common LoRa development boards and transceiver modules can be used
as interfaces with Reticulum. You can refer to the following external resources

path to a destination. Every Transport node participating in a Reticulum network will only

Node Types
----------
Currently, Reticulum distinguishes between two types of network nodes. All nodes on a Reticulum network
are *Reticulum Instances*, and some are alo *Transport Nodes*. If a system running Reticulum is fixed in
one place, and is intended to be kept available most of the time, it can be a *Transport Node*, by enabling
it in the configuration.
This distinction is made by the user configuring the node, and is used to determine what nodes on the
network will help forward traffic, and what nodes rely on other nodes for wider connectivity.
If a node is a *Instance* it should be given the configuration directive ``enable_transport = No``, which
is the default setting.
If it is a *Transport Node*, it should be given the configuration directive ``enable_transport = Yes``.

As an example, in a network based only on radio transceivers with an average link distance of 15

The design and constants of the decay and delay functionality in the announce propagation is subject
to change and optimisation as real-world usage is explored. The announce propagation speed can be
increased at the cost of increased bandwidth consumption.

Node Types
----------
Currently Reticulum defines two node types, the *Station* and the *Peer*. A node is a *station* if it fixed
in one place, and if it is intended to be kept online most of the time. Otherwise the node is a *peer*.
This distinction is made by the user configuring the node, and is used to determine what nodes on the
network will help forward traffic, and what nodes rely on other nodes for connectivity.
If a node is a *Peer* it should be given the configuration directive ``enable_transport = No``.
If it is a *Station*, it should be given the configuration directive ``enable_transport = Yes``.
