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.

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.

`"ecio"`	The CDMA1x Ec/Io, in dBm, given as a floating point value (signature `"d"`).

The "Evdo" property

Evdo  readable   a{sv}

Dictionary of available signal information for the CDMA EV-DO access technology.

This dictionary is composed of a string key, with an associated data which contains type-specific information.
