The "at any signal
strength" phrase has never been true (I color changed it to make it
stand out in your quote). It's C/I is only low when signals are much
higher than sensitivity. For links at the further distance
(when signal is near sensitivity) Canopy C/I is much like any other
technology.

I think its 3db for 1X mode at any
signal strength and 10db for 2X mode
and signal has to be -65 to achieve 2X mode.
