# Application settings… - Transmission groups
Normally, the requests for measurements sent over radio using S2 PC nodes are transmitted one after the other. For big systems, with multiple radio PC nodes and many radio sensor nodes the whole polling procedure may take long time to perform, and to shorten that time, transmission groups can be used.
If transmission groups are enabled, the system may send radio requests via its radio PC nodes in parallel so radio nets from separate groups are polled at the same time.
This function can only be used if radio nodes from the separate groups are set in such a way that their radio nets don’t interfere over radio.
To enable the transmission groups select ‘Enable’ box.
## Create/edit transmission groups.
Click ‘New group…’, enter group name and click OK. To edit select the group and click ‘Edit…’.
## Assigning radio PC nodes to transmission groups
After the groups are created, drag the PC nodes to the groups of your choice. Please remember the PC nodes which may interfere over radio must be in the same group.
Click ‘Apply’ and sign to save the new settings.
Please note you have to restart the Boomerang service on the server to apply the changes.

## 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/boomerang-2-system-administrator-manual/menu_-_administration/application_settings_-_transmission_groups.md?ask=&goal=
```
`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.
