5.4.3 Transmit Power Reduction at the Band Edges

The 4.9 GHz variant does not apply any band edge power reduction.

5.5 5.4 GHz Specific Frequency Planning Considerations

To fully utilize the 5.470 to 5.725 GHz of allocated spectrum the operator must adjust the

lower center frequency attribute in the installation wizard, described in detail in 8.3.5 “Install

Wizard Pages” Adjustment of the lower center frequency allows the operator to slide the

available frequency settings up and down the 5.4 GHz band. See Figure 13.

5.5.1 Raster Considerations

The PTP 400 Series bridge 5.4 GHz variant operates on a 12 MHz channel raster that is set

to odd center frequencies. See Figure 13.

5.5.2 Fixed Frequency Operation

When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the

operator can set the operating frequency independently in both directions to any of the center

frequencies available in i-DFS mode using the ‘Default Raster’ setting. For the expert user

further granularity can be obtained by turning off the ‘Default Raster’. In this mode the

operator is able to select any odd frequency that sets the channel in-band.

5.5.3 Transmit Power Reduction at the Band Edges

The 5.4 GHz variant does not apply any band edge power reduction.
