The interference observed in
Figure 239 for the channel at 5740 MHz during the recent two
hour period is not compatible with satisfactory operation a PTP 670 link.
The situation is, if anything, even worse in the channel at 5780 MHz, as shown in
Figure 240 ,
where the interference level was historically worse, and in the recent period was consistently in
the range -52 dBm to -58 dBm.
Figure 241 shows the recent history of the channel at 5835 MHz. In this case, the peak
interference is less than -80 dBm. This channel is likely to support satisfactory operation at a
receive signal level of -60 dBm or greater.
