Radio frequency is measured in Hertz (Hz).

Table 14 Radio Frequency Conversion

1 kHz = 1000 Hz
1 MHz = 1000 kHz (1000000 Hz)
1 GHz = 1000 MHz (1000000 kHz)

7.4.1 Frequency Ranges

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

Figure 41 Frequency Ranges

In this figure, A is the WiMAX frequency range. "WiMAX frequency range" refers to the
entire range of frequencies the ZyXEL Device 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 ZyXEL Device searching for a connection.
Have the ZyXEL Device 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 ZyXEL Device 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.

7.4.2 Configuring Frequency Settings

You need to set the ZyXEL Device to scan one or more specific radio frequencies to find an
available connection to a WiMAX base station.
