and the operating frequency/bandwidth will be determined by the Best AU
mechanism (including the optional use of the Preferred AU feature). Otherwise the
SU will try to associate with the first AU it finds. If no AU is found, the SU will
start another scanning cycle.
4.2.6.2.3 Frequency Definition Submenu in AU
The Frequency Definition submenu in AU includes the following parameters:
4.2.6.2.3.1 Sub-Band Select
This parameter is available only if the country code supports two or more
Sub-Bands. For information on how to view the Sub-Bands supported by the unit
and the supported parameters' values and options, refer to section “Show Country
Dependent Parameters” on page 72.
The range depends on the number of Sub-Bands supported by the country code.
The default selection is Sub-Band 1.
4.2.6.2.3.2 Frequency
The Frequency parameter defines the transmit/receive frequency.
The range depends on the selected Sub-Band.
The default is the lowest frequency in the Sub-Band. In the current version, the
default frequency for both Sub-Bands is 4947.5 MHz.
In units operating in the 4.9 GHz Japan band with a 10 MHz bandwidth, the
following rules must be met for full compliance with regulations:
1 When operating at 4945 MHz, the Transmit Power parameter in the AU should
not be set to a value above 11 dBm. The Maximum Transmit Power of the SU
should not be set to a value above 10 dBm.
2 When operating at 5055 MHz, the Transmit Power parameter in the AU should
not be set to a value above 13 dBm. The Maximum Transmit power of the SU
should not be set to a value above 10 dBm.
This requirement, although not indicated in the certification document, is needed
following the tests performed in the certification lab.
