Or thereabouts.  Our newest link was engineered for -43.  No smoke.

What do ya engineer it for? Most of the licensed stuff I've dealt with has been engineered to be hotter than -40.

yeah, 2048QAM, but what is your fade margin from the threshold required to run at 2048QAM vs. when it will step down to 256QAM and no longer be a 1 Gbps radio?

If I recall right an IP20C requires an RSSI of something like -57.5 to operate at 2048QAM and will become a 256QAM radio at -63 or thereabouts. Not much fade margin. Not something you can reliably predict as a five nines true 1Gbps link pretending to be a fiber patch cable between two routers.

Unless you're running it at sub-4km distances with 60cm size antennas and the normal RSL is -35.0....

    We just put up a Ceragon IP20c link last week, 3.5 miles, one 60Mhz
    frequency pair, 1030Mbps full duplex using 2048QAM, uses two cores
    (same frequency) in a single FODU chasis and a combiner on the
    antenna.  Looks like any other single FODU install, very clean.  Not
    inexpensive however.
