5.7.1 Raster Considerations
The PTP 600 Series Bridge 5.8 GHz variant operates on a 10 MHz channel raster (for 30
MHz channel bandwidth) and 6 MHz for the variant channel bandwidths 5, 10 and 15 MHz.
The channel raster is set to even center frequencies. See
1010HFigure 22 to 1011HFigure 25.
5.7.2 Transmit Power Reduction at the Band Edges
Operation at or near the 5.8 GHz band edges can results in a lower maximum transmit power.
In some configurations the PTP 600 Series Bridge solution reduces the power when
operating at the edge channels. The amount of reduction, if any, is dependant on the region
code of the region of operation. This currently only affects systems configured with Region
Code 1.
The power reduction in the edge channels for 5 MHz, 10 MHz and 15 MHz is presented in
1012HTable 9 (for region code 1 ONLY).
