WiMAX State This field displays the status of the WiMAX Modem’s current connection.
• INIT: the WiMAX Modem is starting up.
• DL_SYN: The WiMAX Modem is unable to connect to a base station.
• RANGING: the WiMAX Modem and the base station are transmitting
and receiving information about the distance between them.
Ranging allows the WiMAX Modem to use a lower transmission
power level when communicating with a nearby base station, and a
higher transmission power level when communicating with a distant
base station.
• CAP_NEGO: the WiMAX Modem and the base station are
exchanging information about their capabilities.
• AUTH: the WiMAX Modem and the base station are exchanging
security information.
• REGIST: the WiMAX Modem is registering with a RADIUS server.
• OPERATIONAL: the WiMAX Modem has successfully registered with
the base station. Traffic can now flow between the WiMAX Modem
and the base station.
• IDLE: the WiMAX Modem is in power saving mode, but can connect
when a base station alerts it that there is traffic waiting.
Bandwidth This field shows the size of the bandwidth step the WiMAX Modem uses
to connect to a base station in megahertz (MHz).
CINR mean This field shows the average Carrier to Interference plus Noise Ratio of
the current connection. This value is an indication of overall radio signal
quality. A higher value indicates a higher signal quality, and a lower
value indicates a lower signal quality.
CINR deviation This field shows the amount of change in the CINR level. This value is
an indication of radio signal stability. A lower number indicates a more
stable signal, and a higher number indicates a less stable signal.
RSSI This field shows the Received Signal Strength Indication. This value is a
measurement of overall radio signal strength. A higher RSSI level
indicates a stronger signal, and a lower RSSI level indicates a weaker
signal.
A strong signal does not necessarily indicate a good signal: a strong
signal may have a low signal-to-noise ratio (SNR).
UL Data Rate This field shows the number of data packets uploaded from the WiMAX
Modem to the base station each second.
DL Data Rate This field shows the number of data packets downloaded to the WiMAX
Modem from the base station each second.
Tx Power This field shows the output transmission (Tx) level of the WiMAX
Modem.
System Status
System Uptime
This field displays how long the WiMAX Modem has been running since
it last started up. The WiMAX Modem starts up when you plug it in,
when you restart it (ADVANCED > System Configuration >
Restart), or when you reset it.
Current Date/
Time This field displays the current date and time in the WiMAX Modem. You
can change this in SETUP > Time Setting.
