6.3 Frequency Settings
Use this screen to have the WiMAX Device to scan one or more specific radio frequencies (given by
your WiMAX service provider) to find available connections to base stations.
Note: The frequency band varies for different models. See Section 1.1 on page 17 for
more information.
Mode Select Select how the WiMAX Device connects to the base station.
• Auto Connect Mode - The device connects automatically to the first base
station in range.
• Network Search Mode - The device scans for available base stations then
connects to the best one it can.
• NSP Mode - This allows the WiMAX Device to connect to a base station with
a user-specified NSP ID. To specify the NSP ID, select a result in the list and
click Connect. The WiMAX Device will automatically connect to a base
station with the same NSP ID, and the best CINR or RSSI.
• NSP/NAP Mode - This allows the WiMAX Device to connect to a base station
with a user-specified NSP ID and NAP ID. To specify the NSP ID and NAP ID,
select a result in the list and click Connect. The WiMAX Device will
automatically connect to a base station with the same NSP ID and NAP ID,
and the best CINR or RSSI.
• NSP/NAP/BSID Mode - This allows the WiMAX Device to connect to a base
station with a user-specified NSP ID, NAP ID and BSID. To specify the NSP
ID, NAP ID and BSID, select a result in the list and click Connect. The
WiMAX Device will automatically connect to a base station with the same NSP
ID, NAP ID and BSID, and the best CINR or RSSI.
BSID This displays the MAC address of a base station within range of the WiMAX
Device.
NSP This field displays the NSP ID.
NAP This field displays the NAP ID.
Preamble ID The preamble ID is the index identifier in the header of the base station’s
broadcast messages. In the beginning of a mobile stations’s network entry
process, it searches for the preamble and uses it to additional channel
information.
The preamble ID is used to synchronize the upstream and downstream
transmission timing with the base station.
Frequency
(MHz)
This field displays the radio frequency of the WiMAX Device’s connection to the
base station.
Bandwidth
(MHz)
This field displays the bandwidth of the base station in megahertz (MHz).
RSSI (dBm) This field displays the Received Signal Strength Indication (RSSI), which is an
overall measurement of radio signal strength. A higher RSSI level indicates a
stronger signal.
CINR (dB) R3/
R1
This field displays the average Carrier to Interference plus Noise Ratio for the
current connection. This value is an indication of overall radio signal quality,
where a higher value means a better quality signal.
