Hey Lee, I had a friend of mine install an outdoor mesh network over fairly large high-end vacation park. The mesh was fine (operating on 11a). However, the entire park was trashed in the 2.4 channels. WiFi simply would not work anywhere (unless you were near the AP and behind a metal building).
Here are the notes: Rolling signal ranging for 1.9 (PSC) to 2.7 GHz. I was able to get an Agilent scanner and was able to pinpoint the general area of noise to be the tower located about a 1/8 mile from the property. The was a large parabolic dish point in the general direction of the property. We suspected a bad cable on antenna. We contacted [insert the name of the tower corporation here], and were told to prove it (yes they were not nice about it). After a month of testing, we obtained the services of an attorney. One well written letter, and the antenna disappeared. They did not tell us it was removed. We only found out after walking the property almost a month later. Informing us the antenna was removed would have indicated an issue on their side, which they still to this day will not admit. There are heavy fines associated with producing garbage, knowing it, and not doing anything to resolve it. This entire process took months to resolve!!!! If you have this issue, you will have to fight it tooth and nail!!!!! If you want more details, contact me directly. On a lighter note, I¹ve worked with mixed cell, pager, WiFi ³leaky coax² systems with good results providing you know your limitations. -Emerson On 10/16/09 2:44 PM, "Lee H Badman" <lhbad...@syr.edu> wrote: > A bit off the beaten path Knowing that carriers are operating in licensed > frequencies, and that the WLAN and anything else beyond radio that I can think > of in use on campus does not, I¹m wondering if anyone has any input on: > > - Cases where a new or existing cell site on campus interfered with > anything- lab equipment, etc. > - If it ever happened, how was the mitigation process, and it was > because of a carrier freq harmonic, I¹d guess- not the licensed freq band > itself? > > We¹re not experiencing anythingjust curious looking forward. > > -Lee > > Lee H.
