<p class="MsoNormal"><span style="mso-fareast-language:EN-US">We are seeing a similar thing. We have taken that into account within our fade margin. Only seeing 2-3dbm difference on the one or two 5ghz links we have. We have notice more of a hit on the 18ghz
links but it only seems to be at night. I think its more related with humidity and temperature inversions added with smoke worse then last year. Noise floor has not changed.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Nothing too substantial during the day on any of our 5GHz, 24GHz or 80GHz links. Plenty of early AM thermal ducting events that seem worse than usual on 5GHz. Not sure how bad the smoke is there,
but our visibility was down to ~4km at the worst.<o:p></o:p></span></p>
