7.3.1 Frequency Ranges
The following figure shows the WiMAX Modem searching a range of frequencies to find a
connection to a base station.
Figure 35 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.
User's Guide
DESCRIPTION

available channels in ascending numerical order.
Note: The Bandwidth field is not user-configurable; when the
WiMAX Modem finds a WiMAX connection, its frequency
is displayed in this field.
Contact your service provider for details of supported frequencies.
