Click the icon to display the Signal Quality window. The window displays:
•
The active network: the network that is currently being used for your data
connection. For example: "3G (EVDO Rev A)".
•
3G or 4G status:
· Connection status. For example: "Connected".
· Brief description of the signal strength. For example: "Good signal (60%)".
· Tables that show the coverage type, RSSI, and Ec/Io (for 3G) or CINR (for
4G).
RSSI reflects the signal strength of the network.
Ec/Io is a dimensionless ratio of the average power of a channel, typically
the pilot channel, to the total signal power.
CINR stands for Carrier to Interference-plus-Noise Ratio, and is a
measurement of signal effectiveness.
The first table also shows the type(s) of 3G service you have: 1X, 1xEV-DO,
or both. (To determine whether you have EV-DO Rev. 0 or Rev. A service, use
the text near the 3G icon; see
on page
53.)
