Some unscrupulous operators also may use them "Tsunamis" to kill/squat on the spectrum to prevent new commers. This is a large part of the advantage of using sectorized, is you find out where the noise sources are and engineer around them. If you are in their direct path and close, it may mean changing cell site locations or frequency range. The good news is its probably a very directional antenna, and feasible that you could not interfere with them by moving your cell site location. There are several other brands other than Tsunmai that also allow use of all the channels. Its usually the outcome of older legacy gear that attempted 45mbps or higher links.

Subject: [WISPA] What the heck chews up 100mhz of 5.8ghz?!?

While installing a new canopy accesspoint today, in an unserved
community with no other wireless isps and little else, I discovered that
I have about a -56 avarage across the entire swath of 5750mhz thru
5845mhz... what the hell?!?!? It's a small area deployment and we had
planned on a simple low gain omni, but not now... I don't know who or
what but 100mhz, is that really necessary? I'm going to take an sm later
and see if I can get a better picture and determine the direction of
these signals and see if there's going to be any way to make this work.
Out in the middle of nowhere. But does anyone have any idea what in gods
name could occupy this much continuous spectrum in 5.8?
