The results of the testing showed that the WiMAX transmit signal could cause significant problems to a satellite digital signal well in excess of 7.45mi distance. At the extreme measurement distance, the video program was fully operational with the WiMAX carrier centered on the video carrier. However, the data BER was degraded from a nominal 10-8 to a BER of 10-4. This is an unacceptable quality of service in the digital telecommunications industry.

Subsequent calculations based on the initial measured data, and scaling with ITU criteria for WiMAX output power along with additional path loss, resulted in a required separation distance of 172mi to reduce the level of interference to meet the -10dB specification. Combining the two analyses, from a flat nonblocking terrain to a wooded hilly terrain, results show that the criteria whereby FSS antennas cannot co-exist with WiMAX systems ranges from 31mi to more than 124.25mi depending on the local terrain and the WiMAX output levels.

Did the FCC not see this coming, or have they closed down all their engineering operations in favor of lawyering and disbursement of lobbying funds?

well what we need to do is crank up a WiMAX network full wattage and see what happens.

what is C-Band still used for btw? i know that home owners no longer tune it as the big 1m dish is dead.
