Note: It may take several minutes for the WiMAX Modem to find a connection.
• The WiMAX Modem searches the DL Frequency (
頻率
) settings in ascending
numerical order, from [1] to [9].
• If you enter a 0 in a DL Frequency (
頻率
) field, the WiMAX Modem immediately
moves on to the next DL Frequency (
頻率
) field.
• When the WiMAX Modem connects to a base station, the values in this screen
are automatically set to the base station’s frequency. The next time the WiMAX
Modem searches for a connection, it searches only this frequency. If you want
the WiMAX Modem to search other frequencies, enter them in the DL
Frequency (
頻率
) fields.
The following table describes some examples of DL Frequency (
頻率
) 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.
1
In the DL Frequency [1]
( 頻率
[1]) field, enter 2510000 (2510000 kilohertz
(kHz) is equal to 2.51 gigahertz).
2
In the DL Frequency [2] (
頻率
[2]) field, enter 2525000.
3
In the DL Frequency [3]
( 頻率
[3]) field, enter 2600000.
4
In the DL Frequency [4]
( 頻率
[4]) field, enter 2625000.
Leave the rest of the DL Frequency (
頻率
) fields at zero.

The WiMAX Modem
searches at 2500000
kHz, and then searches
at 2550000 kHz if it has
not found a connection. The WiMAX Modem
searches at 2500000 kHz
and then at 2550000 kHz if
it has not found an
available connection. If it
still does not find an
available connection, it
searches at 2600000 kHz.
