5 General Considerations
5.1 Spectrum Planning
The PTP 600 Series Bridge has two frequency variants in its product range.

5.4 GHz ETSI 5 GHz band B, USA UNII Band 5470-5725 MHz 30 MHz 10 MHz
5.8 GHz USA ISM Band / ETSI 5 GHz band C 5725-5850 MHz 30 MHz 10 MHz

There are two distinct approaches to 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. I-
DFS 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.
