Radar Avoidance, i-DFS and Variable (Narrow) Bandwidth Operation

PTP 600 Series bridges do not support operation with 5, 10 or 15 MHz channel bandwidth in
regions where radar avoidance is enabled.
NOTE: Radar avoidance requirements in the 5.4GHz band in the EU is detailed in
specification EN 301-893 version 1.4.1 and in the US in the specification FCC part 15.437.
Radar avoidance at 5.8GHz is applicable to EU operation and the requirements are currently
as defined in EN 302 502.
5.4

Variable Channel Bandwidth Operation

The selection of Channel Bandwidth depends upon the PTP bridge variant:
x
For PTP 25600, PTP 54600, PTP 58600 and PTP 59600, Channel Bandwidth may be 30,
15, 10 or 5 MHz.
x
For PTP 48600 and PTP 49600, Channel Bandwidth may be 20, 10 or 5 MHz.
The 30MHz channel widths are available where allowed by local regulations and subject to
some restrictions on channel choice.
Lite versions of the PTP 600 products do not support a Channel Bandwidths of 5 MHz.
Configuration of the variable bandwidth operation must be symmetric, that is, the Transmit
and receive channels must use identical Channel Bandwidths.

PTP 25600 Specific Frequency Planning Considerations

The supported 2.5GHz frequency range is split into three bands, according to the bands
specified in the FCC BRS-EBS Post-Transition Band plan (only for PTP 25600 and Region
Code 16):
x
Lower: 2496 MHz to 2572 MHz with a 5.5MHz channel raster (76 MHz total).
x
Middle: 2572 MHz to 2614 MHz with a 6 MHz channel raster (42 MHz total).
x
Upper: 2618 MHz to 2690 MHz with a 5.5 MHz channel raster (76 MHz total).
NOTE: For the PTP 25600 product variant, the unit will only operate in Fixed Frequency
mode, and the user is unable to select i-DFS.
