Chapter 4 - Operation and Administration
* The frequency 5725 MHz is illegal and cannot be used.
CAUTION
For units installed in the United States using FCC Country Code in the 5470-5600 and 5650-5725
MHz bands, the following guidelines must be followed:
The operating frequency of either a master or a client device installed within 22 miles (35
kilometers) of a Terminal Doppler Weather Radar (TDWR) location shall be separated by at least 30
MHz (center-to-center) from the TDWR operating frequency. For TDWRs location information refer
to FCC KDB 443999 or to http://www.spectrumbridge.com/udia/search.aspx).
The installers and the operators have to register the devices in the Wireless Internet Service
Providers Association (WISPA) UNII Device Interference Advisor (UDIA) sponsored database and
registry, with the appropriate information regarding the location and operation of the device as well
as the installer information; the registration form can be found at
http://www.spectrumbridge.com/udia/home.aspx.
The default frequency is always the minimum allowed frequency in the supported
range for a bandwidth of 10 MHz.
CAUTION
If due to either restrictions imposed by local regulations or any other reason you cannot use the
entire frequency band supported by the selected Country Code, you should disable the Random
Channel Selection option (see
define the frequencies manually
For example, when using the 5.4 GHz FCC Country Code, you may use either frequencies in the
5470-5600 MHz and 5650-5725 MHz bands (with FCC), or frequencies in the 5725-5850 MHz
band.

Tx Power
The sector's Tx Power in dBm.
In 3.65 GHz units the actually available range (using 1 dB resolution) is from 17
to 30 dBm. The default is 30 dBm.
In 3.6 GHz units the actually available range (using 1 dB resolution) is from 20 to
30 dBm. The default is 30 dBm.
The system administrator/installer is responsible for verifying compliance of the
power emitted from the antenna(s) with local regulations and license conditions, if
applicable.
In 4.9 GHz, 5.4 GHz and 5.4 GHz FCC units the HW supports a Tx Power range of
0 to 21 dBm. However, in units using certain Country Codes the actually available
Tx Power range depends also on the maximum allowed EIRP and Power Spectral
Density according to relevant regulations and on the configured Bandwidth and
Antenna Gain:
