Link Harvest: Possible Problem w/3.65 GHz Band? But Inconsistencies Trouble Me.

Not yet ripe for Wetmachine, and makes me wish I were a journalist.

According to this piece, testing of WiMax equipment by a potential user of the 3.65 GHz band caused interference with the neighboring C-Block downlink used by television broadcasters and others for satellite downlink.

Maybe, but there are some things about this that make me wonder what's up.

1)Philadelphia is in an "exclusion zone" to protect Earth Receiver stations. There shouldn't have been anyone functioning in the Philly area on this band.

2) The article notes that the C-Band abuts the top part of the 3.65 GHz-3.70 part of the band, but WiMax operation is restricted to the bottom 25 MHz. It can't be an out-of-band emission or it should have caused serious problems for the neighboring power plants in the exclusion zone operating in the band below 3.65 as well.

Curious . . .
