From what I can gather, without paying for a new scientist subscription, the frequency that WiMax will be operating in the US will not interfere with C band satellite.
The interference was obtained when the WiMax radios were tested on the higher frequencys that C-Band uses, which they can run on but wont.

After reading the report, it more than likely sounds as if they are also trying to include other forms of terrestrial based systems in the mix.
But also according to the report BWA is operating on the same frequency range as the CB for it's satellite downlinks.
On Wikipedia:
"The 5.4GHz band (5.15–5.35/5.47–5.725/5.725–5.875 GHz) is used for IEEE 802.11a WIFI and cordless phone applications, leading to occasional interference with C band weather radars."
So it's clearly a frequency issue in other countries, as C-band operates here in a lower frequency, and the current set frequencies for WiMAX are 2.5GHZ and not 3.4-5.4Ghz which is what C-band operates.
In short, the terrestrial signal from the WBA is overpowering the CB signal and is causing the receiver to go apeshit because they are both operating on the same frequency range. |
