I have a wireless internet connection with the small dish on the roof because of where I live. I ave had the provider or years.I get notifications on my cell phone when the home network looses the internet connection.

Last night we were in Salt Lake watching the Harlem Globetrotter and the home network dropped the internet connection and came up 5 times between 3 and 9 PM. No biggie, we were not home. I just thought the provider had a problem (unusual). Today at about 3PM I lost internet connection. I called tech services and was told their system had detected radar and shut down. What the heck is that? She knew exactly how many minutes it would be before the system would be back up and it was. She also said SHE could not even connect to my dish to trouble shoot. It happened again around 4PM. I called again and got the same tech. She gave me the same excuse. I said BS I want to talk to a supervisor.

He said essentially the same thing, the system detected radar and the "GOVERNMENT REQUIRES US TO SHUT DOWN ND WE HAVE NO CONTROL OVER IT". He also told me how may minutes it would be before the system came up and he was right.

I have been a Ham radio operator for 40+ years so I understand RF band plans/allocations and who is primary and who is secondary in any given band and the no interference requirement of the secondary allocation. I have no idea what frequency my ISP operates on but I doubt it is in the radar spectrum. An harmonic maybe but I would think only the first harmonic would be a problem and that is highly unlikely.

Has anyone heard of this or know what could be going on?

Please, don't turn this into a "it's the government/Big Brother controlling your life" thread. I really would like to hear from anyone that knows what or thinks might be/have gone on.

Where yat Richard?

As a former isp provider he should have the straight answer.

Question to me is, where is that 'radar' signal coming from?

Exactly!!!

The first level tech said like things that if an airplane came too close to the tower. The tower is about 2 miles away and I can see it if I am on the roof. Huh!!!

The Ogden Hinkeley regional airport is about 5 miles east. The tower is 2 miles SE and both have been there for ever and the tower is not line of site to the airport which it would have to be to cause interference given the frequencies involved.

Just curious, what freq is typical for radar?

One of the conditions of opening up the radio spectrum for commercial and public use by the FCC is that all radios must auto-detect military radio equipment using adjacent frequencies and shut down for a certain period of time until the military use completes. This is the first time I've heard of anyone's home Wi-Fi being affected by this clause, but your ISP is probably giving you the straight story. Your only alternative is a wire- or fiber-based service.

Apparently quite broad!

Or a different isp using a different freq. Back to where dat come from?

I have no idea what is "typical". It really depends on the application. The radar band extends from about 200Mz to 110 GHz. The optimal frequency range for long range radar seems to be 8-12GHz. Dual band routers in your house are either 2.4 or 5 GHz. I do not know the frequency that my provider transmits the signal to my house but I doubt it interferes with any radar in the area.

During WWII the frequency was in the MHz spectrum.

The frequency of the signal will determine how far it can be received given the same amount of transmitting power and the same gain antenna.

Low frequency and high frequency signals bounce off the ionosphere and are reflected around the world. That is why I can talk to someone in Australia (eg.) on 14Mhz (eg.). If we are in a high sun spot cycle (every 11 years) signals as high as 50Mz or higher can be transmitted over longer than normal distances.

Sorry to get carried away.You asked.

Cue the theme from X files.

Sorry guys, I passed out when we won the Super Bowl and just woke up ....

The feds have determined to force wireless ISP's radios to shut themselves down when frequences are sensed that interfere with military and civilian aircraft frequencies. Frequencies that the feds are constantly adding. It is becoming a nightmare for us, and I am glad I am out of the business now.

Anyway, if you live out of the metro area and rely on wireless ISP's it is just part of the equation. I used to tell my customers, if you want 100 percent uptime, move to California LOL.

I hope that answers the question ....

Yeah Broncos!
