Oxygen absorption peaks near the 60 GHz point at around 11 dB/km. Per NOAA in my area, we'll see a rain that is at least 4.76"/hr measured on a 5 minute interval every year. That's often enough for me. That's about 120 mm/hr. That's about 30 - 40 dB/km.
Yes, rain does have a significant impact on 60 GHz. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Adam Moffett" <[email protected]> To: [email protected] Sent: Thursday, October 19, 2017 3:17:51 PM Subject: Re: [AFMUG] IgniteNet Metrolinq Weird.

I just read an article claiming that the atmospheric attenuation at 60ghz is so great that at any range where 60ghz will operate the rain fade is insignificant. ------ Original Message ------ From: "Carl Peterson" < [email protected] > To: " [email protected] " < [email protected] > Sent: 10/19/2017 2:58:56 PM Subject: Re: [AFMUG] IgniteNet Metrolinq <blockquote> Yes, and the LR brackets.

Have any of you tried IgniteNet? Has it been reliable for you? I don't actually need a gigabit in this case, I just need it to be up. </blockquote> -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707 </blockquote> </blockquote>
