7.3.2 Configuring Frequency Settings
You need to set the OX253P to scan one or more specific radio frequencies to find
an available connection to a WiMAX base station.
an available connection to a WiMAX base station.
Use the WiMAX Frequency screen to define the radio frequencies to be searched
for available wireless connections. See
for available wireless connections. See
Section 7.3.3 on page 73
for an example of
using the WiMAX Frequency screen.
Note: It may take several minutes for the OX253P to find a connection.
• The OX253P searches the DL Frequency settings in ascending numerical order,
from [1] to [9].
Note: The Bandwidth field is not user-configurable; when the OX253P finds a
WiMAX connection, its frequency is displayed in this field.
• If you enter a 0 in a DL Frequency field, the OX253P immediately moves on to
the next DL Frequency field.
• When the OX253P connects to a base station, the values in this screen are
automatically set to the base station’s frequency. The next time the OX253P
searches for a connection, it searches only this frequency. If you want the
OX253P to search other frequencies, enter them in the DL Frequency fields.
The following table describes some examples of DL Frequency settings.
7.3.3 Using the WiMAX Frequency Screen
In this example, your Internet service provider has given you a list of supported
frequencies: 2.51, 2.525, 2.6, and 2.625.
