BSID This field displays the identification number of the wireless base station to which
the ZyXEL Device is connected. Every base station transmits a unique BSID,
which identifies it across the network.
Cell ID A base station ’ s coverage area can be divided into multiple cells. This field shows
the identification number of the cell in which the ZyXEL Device is connected.
Frequency This field displays the radio frequency of the ZyXEL Device ’ s wireless connection
to a base station.
MAC address This field displays the Media Access Control address of the ZyXEL Device. Every
network device has a unique MAC address which identifies it across the network.
WiMAX State This field displays the status of the ZyXEL Device ’ s current connection.
• NA : the ZyXEL Device is starting up.
• Fail : The ZyXEL Device is unable to connect to a base station.
• Initial Synchronization : the ZyXEL Device is attempting to locate a base
station.
• Initial DCD (Downlink Channel Descriptor): the ZyXEL Device has located a
base station and is receiving information about a possible downlink
connection.
• Initial UCD (Uplink Channel Descriptor): the ZyXEL Device is receiving
information from the base station about a possible uplink connection.
• Initial Ranging and Calibration : the ZyXEL Device and the base station are
transmitting and receiving information about the distance between them.
Ranging allows the ZyXEL Device 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.
• Initial Negotiation : the ZyXEL Device and the base station are exchanging
information about their capabilities.
• Initial PKM (Privacy Key Management): the ZyXEL Device and the base
station are exchanging security information.
• Initial Registration : the ZyXEL Device is registering with a RADIUS server.
• Running : the ZyXEL Device has successfully registered with the base station.
Traffic can now flow between the ZyXEL Device and the base station.
• Sleep : the ZyXEL Device is in power saving mode, but periodically checks
whether a base station has traffic waiting.
• Idle : the ZyXEL Device is in power saving mode, but can connect when a base
station alerts it that there is traffic waiting.
• Handover : the ZyXEL Device is moving from one coverage area to another,
and is connecting to the new base station.
Bandwidth This field shows the size of the bandwidth step the ZyXEL Device 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 ZyXEL Device to
the base station each second.
DL Data Rate This field shows the number of data packets downloaded to the ZyXEL Device
from the base station each second.
