3.8 WiMAX Technical Reference
Frequency Settings
In a WiMAX network, a mobile or subscriber station must use a radio frequency supported by
the base station to communicate. When the MAX-706 looks for a connection to a base station,
it can search a range of frequencies.
Radio frequency is measured in Hertz (Hz).
Table 9 Radio Frequency Conversion
1 kHz = 1000 Hz
1 MHz = 1000 kHz (1000000 Hz)
1 GHz = 1000 MHz (1000000 kHz)
Frequency Ranges
The following figure shows the MAX-706 searching a range of frequencies to find a
connection to a base station.
Figure 14 Frequency Ranges
In this figure, A is the WiMAX frequency range. "WiMAX frequency range" refers to the
entire range of frequencies the MAX-706 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 MAX-706 searching for a connection.
Have the MAX-706 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 MAX-706 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.
