# Planning the system

The first step is to define the [S2 node types](/s2-radio-system-manual/s2-system-description/s2-node/s2-node-types.md) depending on the parameters and devices to be monitored. Then a list of all the nodes shall be created with their respective firmware versions, interfaces, sensor types and[Radio Net ID and Node ID](/s2-radio-system-manual/s2-system-description/network-structure/radio-net-id-and-node-id.md) parameters.

Then the map of the network shall be created taking into account the fact that the maximum distance of radio communication is about 30 m and it can be smaller in case of thick walls or other obstacles on the way of transmission. 

The PC node shall be located in the middle of the network.

For the nodes which are far away from the PC node [Linking](/s2-radio-system-manual/s2-system-description/s2-node/s2-communication-protocol/linking.md)may be used. It is not recommended to use more than 2 linking nodes on the path especially in the networks with more than 20 measuring nodes because linking increases the time of communication with a node as it includes multiple radio communications. If linking is used, it may be necessary to increase the PC node timeout

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.boomerang3.com/s2-radio-system-manual/installation/planning-the-system.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
