Compass Series HSPA USB Modem Installation Guide
Signal strength and service status. The
number of bars beside the antenna increases as
signal strength increases, to a maximum of five
bars. The ToolTip that displays when you
position the mouse pointer over this indicator
shows the numeric value of the RSSI (Received
Signal Strength Indication) in dBm.
An antenna with a line through it indicates no
service is available (Not in Service). You are
outside of the coverage area or have insufficient
signal strength to maintain a GSM data
connection.
