All in for a Huawei RTN-380 including brackets, antennas, software, licensing,
cables, accessories, etc. comes out between about $22k-30k per link depending
on which options you pick.
Also, if 4Gbps isn't good enough, there is the RTN-380H that does 10G wireless.
The specs on this are insane.
* 10Gbps throughput
* 2000 Mhz channel spacing, 128QAM modulation
* SFP+ interfaces

It is definitely a VERY narrow beam width. Particularly with 60cm antennas. I
wouldn't do it on anything that sways.

You cannot directly compare 11 to 80 GHz. Totally different market. I can't do
beyond 2.5 km at real five to six nines uptime with 80 GHz (even with +18 Tx
power radios).
I can do 60 km with 11 if the link will tolerate some ACM.

It's obviously pricier than the B11, but if you want true symmetrical and a ton
of throughput, you could look at the Huawei RTN-380 radios. These will do 4Gbps
(2Gbps symmetrical) at full licensing, or there are 1, 2, 3Gbps licensing
options. They use 71-76 GHz and 81-86 GHz and so are super easy and cheap to
get (lightly) licensed. These are very popular with carriers outside the US,
but not so much in the US because of all the Huawei/Ciscolobby disputes, but
that has largely been resolved and they have been getting traction here. Let me
know if you want more info, we are Huawei VAR.

Gino,
That seems to be the only configuration that meets the requirement. The way I
see it, in a traditional FDD system you would license an XPIC pair of
frequencies, say 11075 H/V at point A and 11565 H/V at point B. Assuming an 820
running 256QAM you might get 500mbps per polarity per direction, for a two-way
aggregate of 2gpbs. You would have licensed 160MHz at each end of the system,
for a system efficiency of 2gbps/320MHz = 6 b/s/hz.
If you operate a B11 on the same pair of frequencies, you have to use their FD
mode which a typical PCN claims will deliver 736mbps. It would seem that this
can be viewed as a two-way aggregate rate, because the radios still take turns
transmitting as in a true TDMA system. So, the system efficiency here is
736mbps/320MHz = 2.3 b/s/hz -- below the requirement of 3 b/s/hz.
If you switch the B11 to the normal TDMA mode you will need to transmit on the
same frequency from each end of the link. So, in addition to licensing 11075 H
and V transmitting from point A, you also need to license 11075 H and V
transmitting from point B, which adds another 160MHz at each end. The PCNs show
this configuration giving 1.47gbps (again assumed to be an aggregate figure due
to the TDMA mode). This is an efficiency of 1.47gbps/640MHz = 2.3 b/s/hz again.
However, because you have licensed two frequency pairs, each site can also
transmit and receive on the unused 11565 H and V frequencies. If you do this
then you get 2*1.47gbps/640MHz = 4.6 b/s/hz. This seems to be the only valid
configuration, but does this take two radios at each end, or just one?
