5 Radio Link Planning and Regulations
50
NOTE: For PTP 54600, PTP 58600 and PTP 59600, use of the product is allowed according
to local regulations.
There are two alternative methods of spectrum planning:
First an operator can utilize the default spectrum management mode i-DFS (intelligent
Dynamic Frequency Selection). This mode uses the PTP 600 Series Bridge ability to
measure the interference levels in all channels to build up a picture of the interference /
noise levels in all channels. The PTP 600 Series Bridge uses statistical techniques to
select the most appropriate transmit and receive channels. The i-DFS mode can be
influenced in its channel decision process by selectively barring channels from use. The
use of this functionality is described in detail in Section 8.3.7 “Spectrum Management”.
Second, when detailed control of the spectrum allocation is required, it is recommended
that the fixed frequency mode is used to statically allocate transmit and receive channels.
CAUTION: These methods are not allowed when Radar Detection is enabled.
5.2 Licenses and Region Codes
The PTP 600 Series Bridge uses a system of Region Codes to control the operation of the
radio link. The user must ensure the product is configured to conform to local regulatory
requirements by installing a License Key for the correct Region Code.
CAUTION: For the connectorized model, when using external antennas of higher gain than
the appropriate integrated antenna, the regulations may require the maximum Tx power to be
reduced. To ensure that regulatory requirements are met for connectorized installations, refer
to Section 13.6 “Regulatory Issues with Connectorized Units”.
