8.3.1 Frequency Ranges

The following figure shows the WiMAX Modem searching a range of frequencies to
find a connection to a base station.

Figure 30 Frequency Ranges

In this figure, A is the WiMAX frequency range. "WiMAX frequency range" refers to
the entire range of frequencies the WiMAX Modem is capable of using to transmit
and receive (see the Product Specifications appendix for details).
In the figure, B shows the operator frequency range. This is the range of
frequencies within the WiMAX frequency range supported by your operator
(service provider).
The operator range is subdivided into bandwidth steps. In the figure, each C is a
bandwidth step.
The arrow D shows the WiMAX Modem searching for a connection.
Have the WiMAX Modem search only certain frequencies by configuring the
downlink frequencies. Your operator can give you information on the supported
frequencies.
The downlink frequencies are points of the frequency range your WiMAX Modem
searches for an available connection. Use the Site Survey screen to set these
bands. You can set the downlink frequencies anywhere within the WiMAX
frequency range. In this example, the downlink frequencies have been set to
search all of the operator range for a connection.

8.3.2 Configuring Frequency Settings

You need to set the WiMAX Modem to scan one or more specific radio frequencies
to find 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
using the WiMAX Frequency screen.
