DESCRIPTION
This field displays the radio frequency of the OX253P's wireless
connection to a base station.
This field displays the Media Access Control address of the OX253P.
Every network device has a unique MAC address which identifies it
across the network.
This field displays the status of the OX253P's current connection.
•
INIT: the OX253P is starting up.
•
DL_SYN: The OX253P is unable to connect to a base station.
•
RANGING: the OX253P and the base station are transmitting and
receiving information about the distance between them. Ranging
allows the OX253P 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 OX253P and the base station are exchanging
information about their capabilities.
•
AUTH: the OX253P and the base station are exchanging security
information.
•
REGIST: the OX253P is registering with a RADIUS server.
•
OPERATIONAL: the OX253P has successfully registered with the
base station. Traffic can now flow between the OX253P and the base
station.
•
IDLE: the OX253P is in power saving mode, but can connect when a
base station alerts it that there is traffic waiting.
This field shows the size of the bandwidth step the OX253P uses to
connect to a base station in megahertz (MHz).
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.
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.
This field shows the WiMAX signal quality when the OX253P is
transmitting data to the base station. A higher value indicates a higher
signal quality, and a lower value indicates a lower signal quality. The
base station determines downlink (DL) and uplink (UL) modulations
based on this value.
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).
This field shows the number of data packets uploaded from the OX253P
to the base station each second.
