7.3.1 Frequency Ranges
The following figure shows the OX253P searching a range of frequencies to find a
connection to a base station.
Figure 22 Frequency Ranges
In this figure, A is the WiMAX frequency range. “ WiMAX frequency range ” refers to
the entire range of frequencies the OX253P 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 OX253P searching for a connection.
Have the OX253P 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 OX253P 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.
