C-Band and WiMax

[mbarnes]

Despite previous comments made by the wireless industry, C-band users are starting to get interference from new WiMax installations. The new WiMax Internet stuff is coming out with transmitters on 3650-3700. Most of the satellites I did a quick check for start at 3700 for TP 1.

It seems several CBS stations had their network feeds disrupted in the middle of prime time by what ultimately (allegedly) turned out to be new WiMax installations. These things run higher power and may be mounted 200 or more feet in the air. Some studies show the interference can extend up to 175 miles! Their signals can be thousands of times stronger than the satellite signal.

So, if you're watching something on TP1 on C-band, especially on a bird closer to the horizon, you may have problems.

One engineering firm who ran some studies said the Internet providers knew nothing of dBs, antenna patterns, etc. they only understood $$$.

don't see why not

I know wimax is a big thing in this area now. Yes they have there own freqency. But they still had interferance from something. On there system even though they had there own frequency. I tried to get it out of them what was interfering with there system. All they told me is they got it taken care of. NOw this was the wimax people.

This new frequency range around 3.5 ghz is supposed to be registered with the FCC but is still free to use to prevent interference. There are certain restricted areas in which they are not allowed to use internet in this frequency range.
