Regions With Mandatory Radar Detection; Licenses And Region Codes - Motorola PTP 500 Series User Manual

•
Fixed Frequency: This method allows the installer to allocate fixed transmit and receive
frequencies on the units.

4.1.2 Regions With Mandatory Radar Detection

In regions that mandate DFS (Radar Detection), the frequency must always be symmetrical
(transmit and receive on the same frequency). The Spectrum Management Control options
are:
•
Dynamic Frequency Selection (DFS): This method detects interference from other
systems and avoids co-channel operation with these systems, notably radar systems.
•
DFS with i-DFS: This method is similar to i-DFS. It differs in the event that several
alternative channels are equally the best within the 1 dB measurement resolution. In i-
DFS, the ODU selects the lowest channel number out of the set of best channels. In DFS
with i-DFS, the ODU makes a random selection from the equal best channels.

Licenses and Region Codes

The PTP 500 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 10.5 "Regulatory Issues with Connectorized Units".
The license and region codes for each frequency variant are listed in:
•
Section 16.2.2 PTP 54500 Licenses and Region Codes
•
Section 16.3.2 PTP 58500 Licenses and Region Codes
