Figure 12 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.
3.5 The Site Survey Screen
Click the Site Survey tab. Use these screens to configure wireless connection settings.
When you want to have the ZyXEL Device search for a connection to a base station, you have
the following options.
• Use the Manual site survey screen to type in settings yourself. Do this if you want to
configure the ZyXEL Device to scan frequencies that are not in a range (for example,
2.55 GHz, 2.525 GHz, 2.65GHz and 2.675 GHz). See
Section 2.1 on page 23 for an
example of using the Manual screen.
