CHAPTER 3: SYSTEM PLANNING

Where regulatory restrictions apply to certain channels, these channels are barred automatically by the
use of the correct country code. For example, at 5.8 GHz in some European countries, the RTTT band
5795 MHz to 5815 MHz is barred. With the appropriate country code configured for this region, the
ePMP will not operate on channels within this band.
The number and identity of channels barred by the license key and country code is dependent on the
channel bandwidth.
Channel bandwidth
Select the required channel bandwidth for the link. The selection depends upon the ePMP frequency
variant and country code, as specified on page 6-86.
The wider a channel bandwidth the greater is its capacity. As narrower channel bandwidths take up less
spectrum, selecting a narrow channel bandwidth may be a better choice when operating in locations
where the spectrum is very busy.
Both ends of the link must be configured to operate on the same channel bandwidth.
