General Considerations

5.1

Spectrum Planning

The PTP 600 Series Bridge has two frequency variants in its product range. The 5.8 GHz
variant operates between 5.725 to 5.850 GHz (defined as the USA ISM band and the ETSI 5
GHz band C), The 5.4 GHz variant operates between 5.470 to 5.725 GHz (defined as the
ETSI 5 GHz band B). Both product variants operate using a 30 MHz wide channel, with a
channel raster of 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".
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.
