RTTT Avoidance and Other Channel Use Restrictions
Where regulatory restrictions apply to certain channels these channels are barred. The user should
note that the number of channels barred is dependent on the channel raster selected. For example
see the effect of the UK RTTT channel restrictions in
. Barred channels are indicated
by a “No Entry” symbol displayed on the “Spectrum Management” web page, see
“Spectrum Management Control - With Operational Restrictions”.
NOTE:
“Radar Avoidance Enabled” is only valid with 30 MHz channel bandwidth.

5.8 GHz UK RTTT Channel
Avoidance – 15 MHz Channel Bandwidth Only
5.3.3
Radar Avoidance, i-DFS and Variable (Narrow) Bandwidth Operation
Radar avoidance at 5.8 GHz is applicable to EU operation and the requirements are currently as
defined in EN 302 502 v1.1.1
5.4
Variable Channel Bandwidth Operation
Channel bandwidth of 15 MHz
is supported for Only Full versions of the PTP 500.
Configuration of the variable bandwidth operation must be symmetric, i.e. the Transmit and
receive channels must use identical channel bandwidths.
15MHz channel widths are available where allowed by local regulations and subject to some restrictions on channel
choice.
