Mode
Select a connect mode:
• Auto Connect Mode - This allows the BM2022w to connect to any of the
base stations on the list automatically.
• Network Search Mode - This allows the BM2022w to connect to a user-
specified base station. Select this option, choose a base station, click
Connect.
• NSP Mode - This allows the BM2022w 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 BM2022w will automatically connect to a base station
with the same NSP ID, and the best CINR or RSSI.
• NSP/NAP Mode - This allows the BM2022w 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 BM2022w 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 BM2022w 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
BM2022w will automatically connect to a base station with the same NSP ID,
NAP ID and BSID, and the best CINR or RSSI.
Connect Click this to connect to the selected base station.
Disconnect Click this to disconnect from the selected base station.
BSID This field displays the base station MAC address.
NSP This field displays the NSP ID.
NAP This field displays the NAP ID.
Network Type This field displays the network type.
Preamble ID This field displays the 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 center frequency the base station uses in kilohertz (KHz).
Bandwidth
(MHz)
This field displays the frequency band bandwidth the base station uses 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.
Search Click this to have the BM2022w scan for base stations in the frequency band(s)
listed in the Applied Frequency Information table.
