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 

•  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.
