## Description

This interface provides access to extended signal quality information.

## Method Details

### The Setup() method

    Setup (IN  u rate);

Setup extended signal quality information retrieval.

`IN u rate`:

  refresh rate to set, in seconds. 0 to disable retrieval.

org.freedesktop.ModemManager1.Modem.Signal.Setup()

## Property Details

### The "Rate" property

    Rate  readable   u

Refresh rate for the extended signal quality information updates, in seconds. A value of 0 disables the retrieval of the values.
